Software Design for Flexibility How to Avoid Programming Yourself into a Corner

Strategies for building large systems that can be easily adapted for new situations with only minor programming modifications.

Time pressures encourage programmers to write code that works well for a narrow purpose, with no room to grow. But the best systems are evolvable; they can be adapted for new situations by adding code, rather than changing the existing code. The authors describe techniques they have found effective--over their combined 100-plus years of programming experience--that will help programmers avoid programming themselves into corners.

The authors explore ways to enhance flexibility by:
