Chapter 11 Technical Design and Project ... > Mapping to IID Methodologies

Mapping to IID Methodologies

Although the BPM life cycle has been described as an iterative cycle of continuous process improvement, applying the 11 steps of the engineering method sequentially to produce a single automated business process unfortunately still constitutes a waterfall project approach. To make a single pass through the engineering life-cycle activities in one project (or even one iteration of process improvement) is not iterative in the true sense of Iterative and Incremental Development (IID).

IID requires that a complete work product be developed in a number of passes (iterations) through each of the engineering project disciplines, each time producing a testable, tangible increment of the complete deliverable. The weaknesses of the waterfall project approach are well understood: a one-off, up-front requirements specification (followed by sequential application of engineering disciplines) fails because the sponsors cannot be expected to completely foresee all the nuances of the resulting application. Each software project is a new product development so the manufacturing-style production line sequence of treatments doesn’t work.
