70. What can be done if requirements are changing continuously?

Answer: Work with management early on to understand how requirements might change, so that alternate test plans and strategies can be worked out in advance. It is helpful if the application’s initial design allows for some adaptability, so that later changes do not require redoing the application from scratch. Additionally, try to… · Ensure the code is well commented and well documented; this makes changes easier

for the developers.

· Use rapid prototyping whenever possible; this will help customers feel sure of their

requirements and minimize changes.

· In the project’s initial schedule, allow for some extra time to commensurate with

probable changes.

· Move new requirements to a ‘Phase 2′ version of an application and use the original

requirements for the ‘Phase 1′ version.
