Iterative Project Management Module 0 – History and Motivation Prepared by Bob Roggio From Forward and Preface of Textbook: Managing Iterative Software Development Projects By Bittner and Spence.

© 2005 Ivar Jacobson International 2 Iterative Project Management / 01 - Iterative and Incremental Development Objectives Understand some of the shortcomings of the traditional software project management process Understand the notion of change and how an iterative / incremental approach to project management favorable affects project development / management, and Understand why an iterative / incremental approach produces a better product using a better process.

How so? We will discuss in Chapter 1 in considerable detail…

© 2005 Ivar Jacobson International 4 Iterative Project Management / 01 - Iterative and Incremental Development Some Root Causes Culprit is the overall Software Management Process –Flawed process – rigid and inflexible in activities; sequential in form and unresponsive to change –Risk not identified until late –Little chance for Change –Big Bang Approach after long time development. Culprit was Change –During development, change takes place. –Even if / when initial requirements fully understood, time  Change.

But the problem is much more far reaching! We will identify and deal with the developer’s perspective in more detail than we did in the past. We will further delve into the –Customer / User perspective and the –Management Perspective As we collectively work toward developing software with real value to the Customer.

Expect Change; Plan for it; Adapt to it. But our emphasis here will be to embrace change from a Customer, Developer, and Management perspective. Developers must deliver systems that have real business value – whatever the business is. We must learn to manage and develop products while dealing with a moving target! We need an overall software management process that acknowledges, accepts, and embraces change. We must realize fully well that developers, customers, and management view development very differently at times!

Appendix C contains more examples of detailed presentation of example ‘plans’ taken from throughout the book.
