Context-Awareness on Software Artifacts in Distributed Software Development: A Systematic Review

02

Introduction ●

●

Distributed Software Development (DSD) has brought new challenges to software projects caused by physical dispersion and temporal distance Awareness techniques combined with contextual information of the environment improve communication among individuals involved in collaborative work


03

Introduction ●

●

Awareness mechanisms are essential to offer individuals contextual information about the actions that occur on the entities such as software artifacts Physical dispersion and temporal distance among collaborative teams hinder awareness of contextual information about the creation and maintenance of software artifacts


04

Introduction ●

The objective of the research was to identify awareness studies featuring techniques of acquire and present contextual information on software artifacts generated in Distributed Software Development


05

Method ●

●

We made a systematic review to identify aspects upon which researchers have focused about sources of information and visual resources on the development of software artifacts in DSD Also, the systematic review allowed us to analyze and identify current challenges and opportunities for future works


06

Method ●

●

A systematic review aims to evaluate and interpret all available research related to a research question or topic of interest through a rigorous and reliable methodology [Kitchenham, 2007] The systematic review consists of three stages: – – –

Review Planning Review Conduction Review Analysis

Kitchenham, B.A.: Guidelines for performing systematic literature reviews in software engineering. Technical report, EBSE-2007-001, UK (2007) Context-Awareness on Software Artifacts in Distributed Software Development: A Systematic Review

07

Method ●

Research Questions: –

– –

RQ1: What sources of information and visual resources have been used to implement, respectively, the acquisition and presentation of contextual information on the development of software artifacts in DSD? RQ2: What types of software artifacts are addressed by research concerning context-awareness? RQ3: What contextual information and properties are important for context-awareness on software artifacts in DSD?


08

Method ●

Search Strategy: – –

–

Stage 1: manual search in conferences, workshops and journals Stage 2: electronic databases were searched using the keywords “distributed software development” and “context-awareness” Papers written in English and Portuguese, published between 2000 and 2010


09

Method ●

Search Strategy: –

The databases searched were: - IEEE Xplore - ACM Digital Library - EI Compendex - ScienceDirect - Scirus

Discussion ●

Other research topics that can be explored: –

– –

Awareness to overcome issues related to indication of which artifacts have consumed most effort among development teams Context-awareness on the software artifacts of project to the automatic generation of new artifacts Obtain contextual information from sources as tools for Software Configuration Management


25

Discussion ●

●

The merge of previously discussed features could be an interesting research topic, once the acquisition of contextual information from tools such as Software Configuration Management and their presentation to development teams members would increase their awareness about the project Keeping a change history and the relationship among software artifacts could increase the chances of traceability and, thus, propagate the communication in distributed teams through the context-awareness on software artifacts


26

Conclusion ●

●

●

Systematic review of techniques for acquisition and presentation of contextual information on generating software artifacts in DSD The proposals found (57.6%) concerned with the exploration of contextual information on software artifacts from central repository and the own local workspace of developer Version control systems, bug tracking and continuous integration also store contextual information on the creation and maintenance of software artifacts


27

Conclusion ●

●

Timeline and visual resources as graphs and colors are interesting alternative to visualize the evolution of artifact during the software development cycle Change history with information of relationship among artifacts become an important factor increasing productivity and understanding among the team members in collaborative work


28

Conclusion ●

Limitations: – –

–

The search was reduced to a limited number of search engines The studies on the subject of DSD and contextawareness but not contributed with any significant method or technique in the research context were excluded Some studies, mainly related to tools which are not included in the context of DSD, but are useful in areas related to communication and collaboration, were included as well
