Chapter 10: Approaches to System Building

Traditional Systems Lifecycle (aka The Waterfall)

project definition
systems study
design
programming
installation
post-installation

Limitations of LifeCycle Approach: costly, time consuming, inflexible. Will persist in large complex technical projects (Anecdote: FAA AAS)

Alternatives to Systems Lifecycle Approach

Prototyping (aka The Fountain)
- iterative process
- heavy user involvement
- potentially better change to manage
- when does it end?
Application Software Package (aka ShrinkWrap)
- faster, maybe cheaper
- custom suits vs off-the-shelf
- customization available
- RFP: Request for Proposal sometimes: fishing by another name
End-User Development
- faster, quicker, better for users
- risk: may not be rigorous, may not scale, may not be strategic
- great fun
Outsourcing
- to reduce costs
- when existing IT is limited / inferior
- to improve contribution of info sys to bottom lines
- to create new sources of revenue
- risk: hollow corporation

System Building Methodologies

Structured:
- Structured Analysis
- Structured Design
- Structured Programming
- Flowcharts
- limitations: big, inflexible, time consuming
Object Oriented Software Development
- the promise of re-usability
CASE: Computer Aided Software Engineering
RAD: Rapid Application Development
Software Re-Engineering
- reverse engineering
- forward engineering

Chapter 11: Managing Knowledge

If knowledge is a strategic asset (and it is), how do we account for it, invest in it, and keep it locked up at night?
