Module III. Software Design

8

A. Software Design Concepts - 3

The Problem with Software Design

Software requirements are frequently incomplete, incorrect, and inconsistent

Requirements change over time during development

Is a "Wicked Problem”:

Cannot be easily defined so that all stakeholders agree on the problem to solve

Require complex judgements about the level of abstraction at which to define the problem

Have no clear stopping rules

Have better or worse solutions, not right and wrong ones

Have no objective measure of success

Require iteration-every trial counts

Have no given alternative solutions-these must be discovered

Often have strong moral, political or professional dimensions
