National Institute of Industrial Engineering (NITIE), Mumbai, India Abstract Purpose – The purpose of this paper is to empirically examine the organizational culture (OC) of the competing values framework (CVF) on quality management (QM) practices. Specifically, it tests OC on two views, QM practices, i.e. the infrastructure quality and core QM practices. Design/methodology/approach – The proposed hypotheses were tested using empirical data drawn from 262 manufacturing organizations in India. The research model developed was analyzed using structural equation modeling technique. Findings – The findings of this study revealed that the hierarchical and rational cultures are the dominant types of culture, and top management commitment and Six Sigma structure are the most important aspects of the infrastructure and core QM practices in Indian manufacturing organizations. Further, the results of the study showed that group culture and development culture are the most supportive culture types for both infrastructure and core QM practices. On the contrary, hierarchical and rational culture types are the least supportive for infrastructure and core QM practices. The study proposes the need for the mixed culture approach that facilitates the adoption of business strategies Practical implications – Before implementing infrastructure and core QM practices, managers must understand the importance of cultural values in their organization to facilitate effective implementation of QM. Originality/value – This paper contributes to the existing literature by providing empirical evidence leading to the relationship between OC and QM practices. This is the first study that empirically examined the Indian cultural context using CVF, thus contributing to the scarce body of literature particularly in the developing countries.

1. Introduction In the present scenario, organizations are gradually looking into innovative methods to improve products and processes to enhance customer satisfaction and competitive performance. Organizations need to continuously increase the productivity of manufacturing operations, while being flexible for future environmental fluctuations (Gibson and Birkinshaw, 2004; Gorane and Kant, 2016). Numerous studies show that a large number of organizations have adopted quality management (QM) practices to improve the quality and other indicators of performance (Gambi et al., 2015; Patyal and Koilakuntla, 2017; Uluskan, et al., 2016). The International Organization for Standardization (ISO) 9000, which is a widely used QM system across the globe, addresses numerous aspects of QM. It provides standard operating procedures for organizations to produce the best quality products and services and to meet customer requirements (Basir and Davies, 2018). However, Chiarini (2015) reported that ISO 9001 QMS does not eliminate the cost of poor quality and needs to be integrated with total quality management (TQM) or Six Sigma. TQM and Six Sigma have their own separate identities (Chiarini, 2013).TQM results in

employee motivation and operational efficiency, whereas Six Sigma may lead to organizational success and performance (Yizhong and Liping, 2011).TQM has been described in numerous publications as a management philosophy that aims at continuous improvement in all business functions across the organization and improves business performance(Kaynak, 2003; Maroofi, 2012; Patyal and Koilakuntla, 2016).Six Sigma is an organized and systematic methodology for strategic process improvement and new product and service development (Linderman et al., 2003). Moreover, it helps in reducing costs and achieving financial targets (Chiarini, 2013). Although there are numerous proven benefits of TQM implementation, there are some research studies that describe the patterns of failure in its execution process (Gijo and Rao, 2005; Sila, 2007; Abdolshah and Abdolshah, 2011; Zu, 2009; Maroofi, 2012). The key reasons for these failures are partial deployment and lack of understanding of organizational culture (OC) (Cameron and Quinn, 2005). OC is one of the most important variables in the success or failure of TQM implementation (Dean and Bowen, 1994; De Cock, 1998; Kujala and Lillrank, 2004; Metri, 2005; Powell, 1995). Additionally, Six Sigma also recognizes OC as an important factor for its successful implementation (Kwak andAnbari, 2006; Zu et al., 2010). Moreover, to understand how QM practices affect performance, it is essential to understand the organizational contexts in which these practices are implemented (Maroofi, 2012; Sousa and Voss, 2002). Therefore, OC is seen as one of the important contextual factors that faciliatate the effective implementation of QM practices (Gambi et al., 2015; Sinha et al., 2016). The objective of this study is to empirically determine the links between different types of OC on two dimensions of QM practices, namely, infrastructure and core. The past studies have examined the influence of OC on TQM in the developed countries (Zu et al., 2010; Gimenez-Espin et al., 2013; Haffar et al., 2013a, b; Naor et al., 2008; Gambi et al., 2015; Green, 2012). However, the research testing the impact of OC on QM implementation in the developing countries, specifically in India, is relatively rare. Moreover, there is a very limited research investigating the linkages between OC and infrastructure and core QM practices. The study attempts to answer the following research questions. RQ1. What is the degree of emphasis of Indian manufacturing organizations on each of the four OCs? RQ2. What is the degree of development of Indian manufacturing organizations due to infrastructure and core QM practices? This study adopts the competing values framework (CVF) of OC to capture its value orientations. Further, a research model is developed to determine the causal linkages between OC and QM (infrastructure and core) practices. The model is examined at organizational level. The data were collected from 262 Indian manufacturing organizations, and the model was tested using the structural equation modeling (SEM). The remainder of this paper is organized as follows. Section 2 presents the literature review and describes hypotheses development. Section 3 discusses the research methodology, and Section 4 presents results and data analysis. Section 5 highlights the findings and discussion followed by research contributions and implications. Finally, the conclusions and possible directions for future research are summarized in Section 6. 2. Theoretical background and hypotheses development 2.1 QM practices The concept of QM construct differs across many studies; some authors refer as “practices” whereas others call it “critical success factors” or “principles,” but the meaning of constructs is same (Sinha et al., 2016). Practices are the observable aspects of quality which helps in achieving organizational objectives through continuous improvement (Sousa and Voss, 2002).

QM practices are deployed as a means of creating competencies in organizations (Patyal and Koilakuntla, 2015). QM practices have been classified into two major dimensions, namely, infrastructure QM practices and core QM practices (Flynn et al., 1995; Zu et al., 2010; Patyal and Koilakuntla, 2017). The infrastructure practices accord importance to the behavioral characteristics of QM which are people- and culture-oriented, and are related to organizational change and development in the areas of management commitment and leadership, relationships with external customers and suppliers, and the management of human resources. On the other hand, the core practices accentuate on technical aspects which are technique- and methodology-oriented practices, including the use of quality data and information, product design process, use of statistical process control and other process improvement techniques (Wilkinson, 1992; Naor et al., 2008; Yazdani et al., 2016; Zu et al., 2008, 2010). This study has adopted Patyal and Koilakuntla’s (2017) classification of infrastructure and core QM practices. 2.2 Organizational culture OC is defined as “a pattern of shared basic assumptions that the group learned as it solved its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, to be taught to new members the correct way to perceive, think, and feel in relation to those problems” (Schein, 1992, p. 12). OC may be seen as an element that differs from organization to organization and affects the way in which the organization operates (Denison and Mishra, 1995; McDermott and Stock, 1999). This study adopted the well-known CVF developed by Quinn and his/her associate peers (Quinn and Kimberly, 1984; Quinn and Rohrbaugh, 1981, 1983; Quinn and McGrath, 1985) as a tool to evaluate the OC. CVF has been viewed as an important element to measure OC (Shortell et al., 1995). The CVF is built upon two axes: the horizontal axis represents an organizational orientation that divides the organizations into two categories, namely, external and internal operation, and the vertical axis represents the governing structure that shows the organizational tendency of control or flexibility. Based on these two dimensions, four sub-cultures of OC are developed as group, developmental, hierarchal and rational (Denison and Spreitzer, 1991; Cameron and Quinn, 2005). Group culture defines success in terms of sensitivity to people and considers that the organization is an extended family, highlighting it as a friendly place to work with high commitment. Developmental culture defines success in terms of gaining unique products or services and considers that the organization is to be entrepreneurially dynamic and risky place to work with a leading edge. Rational culture defines success in terms of remaining competitive toward market share and penetration, and considers that the organization is meant for results and is goal-focused. Hierarchal culture defines success in terms of dependable delivery, smooth scheduling and low cost, and considers that the organization is a formalized and structured place to work with good efficiency. 2.3 OC and QM practices Culture has been viewed as a vital element in successful implementation of quality improvement programs across organizations (Sinha et al., 2016). Numerous studies examined the impact of OC on QM implementation (Fu et al., 2015; Gimenez-Espin et al., 2013; Sinha et al., 2016; Zu et al., 2011). OC is seen as a differentiating factor that influences the QM practices’ implementation among the organizations (Zu et al., 2011). A large number of organizations are unsuccessful in QM implementation due to the lack of knowledge about cultural dimensions, which underlines the emerging need for studying the role of culture (Prajogo and McDermott, 2005; Patyal and Koilakuntla, 2016). The organization’s values and beliefs help in policy framing, which may affect the implementation of QM practices (Waldman, 1993). For organizations to realize the benefits of QM practices, it is necessary to develop a cultural

environment that supports its implementation (Sousa-Poza et al., 2001; Škerlavaj et al., 2007). Culture is viewed as one of the most influential change agents that helps in QM deployment in an organization (Antony and Banuelas, 2002). Also, for effective implementation of Six Sigma, it is essential to understand the OC (Laureani and Antony, 2016; Zu et al., 2010). 2.4 Hypotheses development 2.4.1 Relationship between OC and Infrastructure QM practices. The flexible OC is positively related with quality improvement program (Shortell et al., 1995). The adoption of quality improvement programs results in a large number of satisfied and loyal customers (Ahire and Dreyfus, 2000; Kaynak, 2003; Patyal and Koilakuntla, 2017). Fulfilling the customer demand every time helps to increase the market share of the organization (Craig and Douglas, 1982; Maroofi, 2012). Further, the quality of an organization’s products and services is influenced by internal and external processes (Flynn et al., 1995; Kaynak, 2003; Prajogo et al., 2016). Suppliers play a vital role in contributing to the buying firm’s produce/service design and process management projects (Kaynak and Hartley, 2008; Gorane and Kant, 2016). Suppliers are the strategic partners that help in building specialized capabilities of the buyer’s organization (Holcomb and Hitt, 2007). Customer relationship and supplier relationship management highlights the need of OC (Naveh and Erez, 2004). The group culture improves the participation of customers and suppliers in organizational activities (Naor et al., 2008). Further, Haffar et al. (2013a, b) state that the group culture is the most conducive culture for the implementation of QM practices. The Six Sigma role structure helps the organization to develop quality problem-solving skills (Zu et al., 2010). The Six Sigma champions provide expert assistance for the improvement of teams and assist the teams in effective decision-making processes (Pande et al., 2002; Zu et al., 2010). The compensation policies include quality-based incentives, compensation based on breadth of skills and incentives for group performance for both TQM and Six Sigma practices (Henderson and Evans, 2000; Raja Sreedharan et al., 2017). These incentives and rewards provided by the management enhance employee motivation and participation in the organization’s continuous improvement activities (Naor et al., 2008). Moreover, incentives are used as an essential element to motivate the workforce for higher performance (Naor et al., 2008). In sync with the CVF theory, the group and development culture represents flexibility and spontaneity orientation. Since the core practices represent the hard practices, the authors propose that flexible and spontaneity orientations have a more significant impact on infrastructure practices as compared to stability/control-oriented organizations. Thus, the following hypotheses are proposed: H1. Group culture has a more significant impact on infrastructure practices as compared to stability/control-oriented organizations. H1a. Group culture has a more significant impact on infrastructure practices as compared to hierarchical culture-oriented organizations. H1b. Group culture has a more significant impact on infrastructure practices as compared to rational culture-oriented organizations. H2. Developmental culture has a more significant impact on infrastructure practices as compared to stability/control-oriented organizations. H2a. Developmental culture has a more significant impact on infrastructure practices as compared to hierarchical culture-oriented organizations. H2b. Developmental culture has a more significant impact on infrastructure practices as compared to rational culture-oriented organizations.

2.4.2 Relationship between OC and core QM practices. A large number of studies revealed that the cultural attributes are linked with core quality improvement practices which assist in developing suitable actions for continuous improvement in products, services and processes (Forza and Filippini, 1998; Hackman and Wageman, 1995; Kaynak, 2003; Rahman and Bullock, 2005; Patyal and Koilakuntla, 2017). Further, the Six Sigma methodology also favors continuous improvement activities through the Six Sigma structured improvement procedure and Six Sigma metrics approach (Zu et al., 2010; Shafer and Moeller, 2012). The implementation of TQM practices like quality information, product/service design, and process management complements the rational culture (Zammuto and O’Connor, 1992). Rational culture facilitates process management by linking each activity to the similar end point (Linderman et al., 2003). Further, group culture facilitates an organizational member’s participation through teamwork, empowerment and open communication which streamline the decision-making process (Naor et al., 2008; Zu et al., 2010). The hierarchical culture promotes standardization of products and services to facilitate the effective implementation of QM (Gimenez-Espin et al., 2013). The low hierarchy facilitates new product development through the contribution of different ideas and efforts from persons (Nakata and Sivakumar, 1996). A hierarchical culture follows the process management techniques like efficiency, stability and error detection and measurement that help in improving the internal processes through preventive maintenance and statistical process control techniques (Maroofi, 2012). The hierarchical and rational culture represents stability and control orientation in the CVF framework. Also, since the infrastructure practices represent the soft practices, this study proposes that the organizations with control orientations have a more significant impact on core practices as compared to the flexibility-oriented organizations. Overall, the above discussion suggests the following hypotheses: H3. Hierarchical culture has a more significant impact on core practices as compared to the flexibility-oriented organizations. H3a. Hierarchical culture has a more significant impact on core practices as compared to the group culture-oriented organizations. H3b. Hierarchical culture has a more significant impact on core practices as compared to the developmental culture-oriented organizations. H4. Rational culture has a more significant impact on core practices as compared to the flexibility-oriented organizations. H4a. Rational culture has a more significant impact on core practices as compared to the group culture-oriented organizations. H4b. Rational culture has a more significant impact on core practices as compared to the developmental culture-oriented organizations. The theoretical discussions and proposed hypothesized relationships have led to the development of the proposed model, for explaining the relationship among OC types, and infrastructure and core QM practices implementation, as shown in Figure 1. 3. Research methodology 3.1 Sampling and data collection A cross-sectional questionnaire survey method was used to collect data for this study. The survey items were grouped into sets, and each set was labeled to help the respondent for easily understanding the content of the survey. The sample of participant organizations

was drawn through a combination of purposive and snowball sampling technique. The purposive sampling technique is used “when the researcher decides what needs to be known and sets out to find people who can and are willing to provide information by virtue of knowledge or experience” (Lewis and Sheppard, 2006). Snowball sampling, which involves asking an informant to suggest another informant, follows purposive sampling (Patyal and Koilakuntla, 2017). The target respondents were plant managers, quality heads and Six Sigma Master Black Belts and Black Belts. A total of 500 respondents from the Indian manufacturing organizations were approached through e-mail and personal visits for data collection. These respondents were requested to complete the designed questionnaire. Out of these 500 respondents approached, 284 respondents agreed and responded, yielding a response rate of 56.8 percent. Out of 284, 22 responses were incomplete. Hence, the data collected from 262 manufacturing organizations were used for the analysis. The detailed profile of the respondents is shown in Figure 2. 3.2 Measures of OC and QM practices The OC is measured using the instrument originally established by Quinn and Spreitzer (1991). The measures for OC types were taken from the empirical studies which have tested OC in the QM context (Naor et al., 2008; Zu et al., 2010) (see Tables AI and AII). The study utilized both TQM and Six Sigma practices while considering infrastructure and core QM practices. The five infrastructure QM practices, namely, “top management support,” “workforce management,” “customer relationship,” “supplier relationship” and “Six Sigma role” are measured using an instrument (Zu et al., 2010). Correspondingly, the five practices are utilized to assess core QM practices, namely, “quality information and analysis,” “process control,” and “product design,” “Six Sigma structure,” “Six Sigma metric” (Zu et al., 2010). Recently, Patyal and Koilakuntla (2017) tested these scales in the Indian manufacturing organizations’ context. This study adopted the validated scale from Patyal and Koilakuntla (2017) for the assessment of QM practices (see Tables AI and AII). The measurement items are measured through perceptual questions on a seven-point Likert scale with the end points of “strongly disagree ( ¼ 1)” and “strongly agree ( ¼ 7).”

4. Results and data analysis 4.1 Tests for reliability and validity analysis This study used Cronbach’s α for measuring the reliability of the instrument. The threshold value of Cronbach’s α should be at least 0.60 and is considered highly reliable beyond 0.70 (Nunnally et al., 1994). The reliability test was performed on QM practices and OC types; all 14 factors’ α value exceeded the threshold limit by a substantial margin, indicating a good reliability of the measurement scales (see Table III). A systematic review of literature was conducted to ensure content validity. Further, the study calculated both the convergent and the discriminant validity. For convergent validity, the composite reliability of all the measures must be above 0.70 (Hair et al., 2010). The QM practices and OC types are above the minimum threshold limits (see Table I). Further, the average variance extracted (AVE) should be above 0.50 (Hair et al., 2010). All the factors of QM practices, OC, the value of AVE, are 0.50 above the minimum threshold value (see Table I). The discriminant validity can be examined by comparing the shared variance between measures with the AVEs of the individual measures (Fornell and Larcker, 1981). Additionally, the maximum shared variance (MSV) should be less than AVE, i.e. (MSVoAVE) and average shared variance (ASV) less than AVE, i.e. ASVoAVE (Fornell and Larcker, 1981). The comparison between the AVEs and shared variance of QM practices, and OC is presented in Table I. Also, the square root of AVE must be greater than the inter-construct correlations (see Table II). The results showed that the shared variance between the measures was less than the AVEs of the individual measures of QM practices, and OC, which, in turn, confirms good construct validity.

4.2 Test for structural model The hypotheses have been tested by using the SEM technique and using the maximum likelihood method (Hair et al., 2010; Maruyama, 1997). The testing confirms a model’s goodness of fit (GOF) and the hypothesized paths between constructs. First, the loading estimates were examined to make sure that they have not changed substantially from the measurement model indicating parameter stability among the measured items, which further supports the measurement model validity (Hair et al., 2010). The structural model is found to fit the data well, as supported by the GOF indices: normed χ2 ( χ2/df ¼ 2.37) is also below the cut-off value of 5 (Hair et al., 2010), RMSEA ¼ 0.072, SRMR ¼ 0.98, CFI ¼ 0.87, TLI ¼ 0.86, IFI ¼ 0.87). Even RMSEA, SRMR are below the cut-off value of 0.10 (Hair et al., 2010). The GOF indices indicates high parameter stability among the measured items in the model. Overall, the model demonstrates a good model fit to the real-world data. The results showed that group culture ( β ¼ 0.36) has a more significant impact, and so does development culture ( β ¼ 0.37) on infrastructure practices as compared to hierarchical culture ( β ¼ 0.23) and rational culture ( β ¼ 0.10), thus accepting H1 and H2. However, the hierarchical culture has a less significant ( β ¼ 0.32) impact on the core practices as compared to the group culture ( β ¼ 0.54) and development culture ( β ¼ 0.32), thus rejecting H3. Rational culture’s impact on the core practices is non-significant thus automatically rejecting H4. The variance explained by structural relationships was 75percent for the core QM practices, and 53percent for infrastructure QM practices. These values indicate a high predictive power of the model. The standardized parameter estimates, t- and p-values, and GOF indices for the proposed model are reported in Table III. 5. Findings and discussion OC is a unique intangible element that can distinguish the organizations from its competitors and also help them to be competitive (Barney, 1986). The manufacturing organizations across the globe necessitate the incorporation of culture types in operations management studies due to the globalization and outsourcing (Zhao et al., 2006). The discussion on research questions and hypotheses is presented in the following sections.

5.1 Answers to research questions RQ1. What is the emphasis degree of Indian manufacturing organization on each of the four OC types? To identify the OC of Indian manufacturing organization (RQ1), the standardized factor loadings of OC have been used to plot the cultural profile (see Figure 3).The number of points on a specific culture determines its strength; the higher score represents the dominant particular culture (Cameron and Quinn, 2005; Valmohammadi and Roshanzamir, 2015). The maximum factor loading on hierarchical culture shows that OC is best explained by this dimension. The results showed the hierarchical and rational cultures as the dominant types of OC. Hierarchical culture (0.61) and rational culture (0.56) had the highest values (see Figure 3). Flexibility and Spontaneity

The Indian manufacturing organizations stress on stability and control, more than flexibility or spontaneity. The organizations must determine their cultural strength to be successful in this competitive environment (Valmohammadi and Roshanzamir, 2015): RQ2. What is the degree of development of Indian manufacturing organizations on each infrastructure QM practices and core QM practices?

The standardized factor loadings of the five first-order infrastructure and core QM practices respectively helped us to investigate the development degree of the Indian manufacturing organization on each of these QM practices (see Figures 4 and 5). In the case of infrastructure QM practices, the maximum factor loading on “top management commitment” was (0.80) while the minimum factor loading on “Six Sigma role” was (0.37). Similarly, core QM practices emphasized “Six Sigma structure” (0.74) more, while the minimum factor loading on “Process management” was (0.06). The results showed the top management commitment and Six Sigma structure as the most developed aspects of infrastructure QM and core QM practices, respectively, in the Indian manufacturing organization. 5.2 Test of research hypotheses The well-known CVF was used to evaluate an organization’s culture. This framework comprises four cultural orientations, which are group culture, developmental culture, hierarchical culture and rational culture. This study tested the relevance of these cultural types and validated them in the Indian context. The results of this study are in agreement with the prior studies (Ambroz, 2004; Buch and Rivers, 2001; Chu, 2003; Irani et al., 2004; Naor et al., 2008, 2013; Zu et al., 2010) regarding the importance of OC to QM. Also, this study calculated the impact of these four culture orientations on infrastructure quality practices and core quality practices: H1. Group culture has a more significant impact on infrastructure QM practices as compared to stability/control-oriented organizations. Infrastructure QM Practices Six Sigma Role

In this study, the proposed model revealed that the group culture is more significantly related to the infrastructure QM practices as compared to the stability/control-oriented organizations (support for H1). More precisely, group culture has shown more significant impact on infrastructure QM practices as compared to the hierarchical and rational cultures (support for H1a and H1b). This result confirms the prominence of the group culture for QM (Prajogo and McDermott, 2005; Naor et al., 2008; Zu et al., 2010). The group culture includes trust, loyalty, attachment and human resources as core values (Zu, 2005). It also facilitates the effective deployment of infrastructure QM practices comprises customer relationship, supplier relationship and workforce management, as these practices emphasize creating internal and external cooperation for continuous improvement (Anderson et al., 1994). Employees in organizations that accentuate the group culture possibly work together with external customers and suppliers, as they draw from the mutual bond of trust in a relationship. For building a solid link with customers and suppliers, it is essential for organizations to involve them in product design or process improvement activities and share information with them, which, in turn, improves quality (Zu, 2005). Also, the group culture must support workforce management through encouraging communication, learning and activities (Cameron and Quinn, 2005). Organizations that give importance to human resources usually emphasize policies that are constructive for developing a competent workforce and employees’ loyalty and commitment to the organization (Zeitz et al., 1997; Zu, 2005). This finding supports prior studies (Zeitz et al., 1997; Klein et al., 1995; Chu, 2003; Naor et al., 2008).These studies have concluded that the cultural characteristics supporting QM implementation result in employee empowerment, human resources and open communication: H2. Developmental culture has a more significant impact on infrastructure QM practices as compared to stability/control-oriented organizations. These results show that the developmental culture is more significantly related to the infrastructure QM practices as compared to the stability/control-oriented organizations (support for H2), which means the developmental culture has a more significant impact on infrastructure QM practices as compared to the hierarchical and rational culture (support for H2a and H2b). These results corroborate with the findings of Page and Curry (2000). For the effective implementation of TQM, an OC that encourages customer focus is desirable (Lakhe and Mohanty, 1994). This has been further proved by several other studies (Bou-Llusar et al., 2009; Kumar and Sankaran, 2007; Prajogo and McDermott, 2005; Naor et al., 2008; Yeo and Neal, 2004; Zu et al., 2010; Gimenez-Espin et al., 2013). Developmental culture demonstrates the tolerance for flexibility (Cameron and Quinn, 2005). Also, this culture supports the approach of Six Sigma that provides training and assigns different roles and responsibilities (Linderman et al., 2003; Zu et al., 2010): H3. Hierarchical culture has a more significant impact on core QM practices as compared to flexibility-oriented organizations. Correspondingly, this study shows less significant impact of the hierarchal culture upon the core QM practices as compared to the flexibility-oriented organizations (rejection for H3). Also, the hierarchical culture has a less significant impact on core practices as compared to the group and development culture-oriented organizations (rejection for H3a and H3b). These findings are in line with Douglas and Judge (2001), who reported that a strong focus on structural control of procedures, operations and work activities helped in improving the organization’s effectiveness and efficiency. The values and beliefs associated with the hierarchical culture are consistent and reliable with the supervisory control of the organization, using a clear line of structure and communication (Quinn and Spreitzer, 1991). However, the past studies mentioned about the lack of significance of the hierarchical

culture for organizational effectiveness (Zu et al., 2010). Agus and Sagir (2001) reported that there were no significant links of hierarchical management with process management. The organizations that stressed the hierarchical culture were the worst performers and their employees reported a low quality of work life (Quinn and Spreitzer, 1991; Yeung et al., 1991). Remarkably, the results of this study showed that a large number of organizations in India were characterized by hierarchical characteristics. Kumar and Sankaran (2007) argued that there need not be a conflicting impact of hierarchy and collectivism on TQM implementation. Further, these authors mentioned that in the Indian context, hierarchy operationalized through the teacher-student relationship between the boss and the subordinate can develop a learning orientation among the organizational members and facilitate TQM implementation. It appears that organizations with an emphasis on the hierarchical culture are more likely to comply with rigorous problem-solving procedures of Six Sigma and to install a Six Sigma role structure to formalize employees’ roles and responsibilities in continuous improvement. Further, the findings recommend that for achieving a premier position in quality levels, organizations must use tools such as Pareto chart, fish bone diagram, affinity chart, and variance plots for improving measurement, process control and systematic problem solving (Cameron and Quinn, 2005): H4. Rational culture has a more significant impact on core QM practices as compared to flexibility-oriented organizations. The results of this study suggest that there is no significant impact of the rational culture on the core QM practices as compared to the flexibility-oriented organizations (rejection for H4). In totality, the rational culture has no significant effect on the core QM practices as compared to the group and development cultures (rejection for H4a and H4b). The infrastructure practices require people- and culture-oriented practices that aim at satisfying customer needs and expectations, improving product and service quality, and enhancing the operational performance (Wilkinson, 1992; Zu et al., 2008). The rational culture stresses on achieving productivity, efficiency and performance, encouraging employees to follow the organizational goals of superior quality using the infrastructure quality practices. Also, employees tend to have less resistance to committing to challenging quality goals and are ready to utilize quality tools and metrics in the routine work. Moreover, for attaining world-class quality, the application of rational culture is desirable (Cameron and Quinn, 2005). The final structural model has been shown in Figure 6. 6. Research contributions and implications The research contributes significantly to the body of knowledge of QM literature in a number of ways. First, this study improved the understanding of the impact of OC on QM. Past studies highlighted the significant impact of OC on the effectiveness of QM programs (Lewis, 1996). Though past studies (Zeitz et al., 1997; Corbett and Cutler, 2000; Kujala and Lillrank, 2004) repeatedly emphasize the magnitude of cultural characteristics that are related to communication, trust and employee participation in QM, the studies ignored the potential effect of culture on the application of the quality methods and tools, which are essential components of QM. This study examined the impact of individual cultural orientations on the two dimensions of QM practices. Second, the SEM used in this study provided a perfect means to analyze the model fit indices. This contribution is essential as the investigation of OC and QM practices helps in advancing the current knowledge concerning the interrelationships between these factors. This study has some key managerial implications. Before implementing infrastructure and core QM practices, managers must understand the cultural values emphasized in their organization to facilitate the effective implementation of QM practices. The group and development cultures appear to be strongly affecting infrastructure and core QM practices;

therefore, managers need to be competent in managing teams, interpersonal relationships and look for innovation and new resources. Further, managers should favor teamwork and help individuals improve their performance, expand their competencies and get rewarded for their contribution to better quality. Therefore, managers must transform their existing culture and move their emphasis toward the values and characteristics of the group and development culture. Also, managers must build a competitive advantage through culture-driven organizational capability based on the characteristics of multiple culture types; they will make it more difficult for competitors to replicate processes and routines. Further, organizations must innovate and frame policies for a perfect work-life balance which makes employees happy and satisfied. Organizations should emphasize supportive OC; this will not only enhance the quality of work life of employees but also help in the increased organizational commitment, job involvement, empowerment, job satisfaction and enhanced productivity level of the organization. 7. Conclusion In a nutshell, the findings of this study are very useful for taking positive steps for improving the quality of products thereby maintaining the healthy industrial growth. The findings of this study revealed the hierarchical and rational cultures as the dominant types of culture and top management commitment and Six Sigma structure as the most important aspects of infrastructure and core QM practices, respectively, in the Indian manufacturing organizations. Also, the study revealed that the group culture and development culture are the most supportive cultures for both infrastructure and core QM practices. On the contrary, hierarchical and rational cultures are the least supportive for infrastructure and core QM practices. The study proposes the need for building a comprehensive culture environment, i.e. the mixed culture approach, that facilitates the adoption of business strategies.

7.1 Limitations and future scope There are some limitations of this research that lead to ways for future research. First, the study is limited to the organizations of a developing country but owing to the cultural dissimilarities, the results of the study may differ in case of other developing countries. Second, the results of the study are limited to manufacturing organizations, predominantly focusing on the automobile sector. However, further research should be carried out on other sectors. Third, the instrument used to measure OC assumes that there is a single culture throughout the organization. However, different departments in the same organization usually maintain an internal culture distinct from the rest of the organization. Fourth, this study used a cross-sectional design for data collection. This study has considered only QM practices; however, the future studies may include supply chain management, lean, Kaizen and sustainability dimension in the measurement model to get more concrete results. Further research is needed to examine the effect of the national culture on QM implementation and the resulting effect on organizational performance. References Abdolshah, M. and Abdolshah, S.
