Title: IS Implementation Risk


1
Chapter 10
  • IS Implementation Risk

2
Risk Components
  • Magnitude of loss
  • Likelihood of loss
  • Exposure to loss

3
Management of Risk
  • Control
  • Information
  • Time

4
IT Project Risk
  • What is loss with respect to IT projects?
  • Failure to gain anticipated benefits because of
    implementation difficulties
  • Higher than expected implementation costs
  • Longer than expected implementation time
  • Technical performance below expectation
  • System incompatibility

5
Project Dimensions Influencing Risk
  • Project size
  • Experience with technology
  • Project structure

6
Mythical Man Month
  • IBM 360 Operating System Brooks
  • Adding people to a late project only makes it
    later
  • partitionable tasks
  • communication and coordination costs

7
Low Structure/Information Requirements
  • The problem of communicating requirements
  • Exponentially greater cost of fixing errors that
    occur early in the system life cycle

8
Contingency Approach to Project Management
  • External integration
  • Internal integration
  • Formal planning
  • Formal control

9
External Integration Techniques
  • Aimed at resolving requirements uncertainty
  • User project manager
  • User steering committee
  • User approval process
  • Joint Application Design (JAD)
  • Prototyping for requirements determination

10
Internal Integration Techniques
  • Aimed at resolving technical design uncertainty
  • Selection of experienced IT team leadership
  • Frequent team meetings
  • Co-location
  • Technical status reviews and updates
  • Maintain low team turnover
  • Import outside technical expertise

11
Formal Planning Tools
  • Project Management Software
  • PERT CPM
  • CMM process conformity
  • Use of defined development methodology
  • Project Office

12
Formal Control Tools
  • Status-versus plan reports
  • Change control and configuration management
  • Milestone reviews

13
Portfolio Risk
  • Consequences of no risky projects
  • Consequences of a majority of risky projects
  • Strategic quadrant - Support, Factory,
    Turn-around, Strategic

14
New IS Effects
  • How do new Information Systems change work?
  • New tasks, new processes
  • New communication patterns
  • New political relationships
  • New technology to learn
  • New skills valued
  • Others?
  • People in an organization may resist the
    implementation of a new IS

15
Cost of Implementation Failure
  • Standish Group study (1995) found that
  • 16.2 of IT projects successful
  • 52.7 of IT projects challenged
  • 31.1 of IT projects impaired.
  • Numerous projects resisted after having been
    declared successful (Krasner 2000).
  • Apparent belief among MIS researchers that user
    resistance contributes to project failure.

16
Conceptualization of Resistance in Acceptance
Studies
17
Definitions of Acceptance and Resistance
  • Acceptance the act of receiving IT use
    willingly (Saga and Zmud 1994).
  • Resistance action or intentional inaction that
    opposes or sidesteps the implementation of new
    information technology.

18
Resistance Tactics
19
Mandatory vs. Voluntary Usage
  • Degree of acceptance makes sense for voluntary
    systems. Does resistance to voluntary systems
    make sense?
  • For mandatory systems, how would grudging
    acceptance be classified?

20
Change in Resistance over Time
  • As alternative forms of resistance are
    prohibited, different forms may be tried
  • Voice ? Work around ? Sabotage or Exit
  • Voice ? Work around ? Grudging acceptance.
  • Resistance may be constructive and disappear if
    reasonable suggestions are heeded.

21
Passive Resistance
  • How frequently do passive forms of resistance
    manifest?
  • Problem of passive resistance and using intention
    to accept as the definition of system success.
  • Effectiveness of passive resistance.
  • Passive resistance and plausible deniability.

Resistance Type
23
Definitions of Acceptance and Resistance
  • Acceptance the act of receiving IT use
    willingly (Saga and Zmud 1994).
  • Resistance action or intentional inaction that
    opposes or sidesteps the implementation of new
    information technology.

24
Some Interpretations of Resistance
  • Resistance is pathological.
  • Resistance as an impediment to legitimate
    management initiatives.
  • Resistance is a risky activity for the resistor.
  • Resistance is a means to preserve personal
    integrity and self-esteem.
