MIS

Objectives

Efficient transaction

Effective problem resolution & decision making support

Information sources

Internal & external transaction

Internal & external transaction + research data

Information time frame

Recent history, current & near future

Historical data, current & future

Process

Algorithmic (very predefined)

Sometimes need human intervention (esp. for decision making)

Users

Operators

Professionals & middle managers

Technology

Mainframe/mini computers

Local processing linked to information resources

Lessons from DP era z z z z z z

Lessons from MIS era z

z

z z

IS/IT investment cannot be justified only in financial means The need for organizational policy (not just DP methodology) From producing data to serving users Data integration is important: using very large database

DP ERA

MIS ERA

SIS ERA

Nature of technology

Computers Fragmented HW limitation

Distributed Process Interconnected SW limitation

Networks Integrated People/Vision limitation

Nature of Operations

Remote from users controlled by DP

Regulated by management services

Available and supportive to users

Issues in systems development

Technical issues

Support business users needs

Relate to business strategy?

Reasons for using the technology

Reducing costs (technology driven)

Support the business (user driven)

Enabling the business (business driven)

Characteristics of systems

Regimented / Operational (internal)

Accommodating / Control

Flexible / Strategic

Relationship Between the Three Eras (Wiseman, 1985) z z

z

Good MIS rely on good DP systems, likewise, good SIS rely on good DP or MIS SIS are not essentially different systems, SIS functions are the same as DP and MIS; SIS differ in their impact on the business SIS may make DP and MIS to be redeveloped when they inhibit potential benefits of the SIS.

Success factors in strategic IS z z z

z z z z

External, not just internal focus Adding value, not cost reduction Sharing the benefits: internally, with supplier & customer Understanding customer Business driven not technology driven Incremental development Use information to develop business

z

Pressures of the market-place often interpreted by IS/IT user

Incremental development z z z
