Requirements and design

Key concepts
 
Client requirements are a notorious problem in many fields. There's a widespread view that the problem is due to clients not making their mind up, or being disorganised. The real reasons run deeper; fortunately, there are effective methods for fixing the problem, which are not as widely known as they should be.
