Evolutionary delivery has many benefits:

• It solves the requirements paradoxes.
  Requirements must be stable to develop reliable results. However, the requirements always change. This is the requirements paradox. Even if you did your utmost best to get complete and stable requirements, they will change. Not only because your customers change their mind when they see results emerging from your developments. Also the developers themselves will get new insights, new ideas about what the requirements should really be. So, requirements change is a known risk. Better that ignoring the requirements paradox, use a development process that is designed to cope with it: Evolutionary delivery.
• It allows us to cope with changing idea's, concepts, market developments, suddenly emerging circumstances, overlooked or unforeseen.
• It provides rapid feedback of the results of decisions, estimations en planning, providing quick learning by project management and developers on better estimations, better planning, better tracking and better delivering results in time.
• It provides customers with a choice of Time to Market. The product under development is always a working, functional product, with the most important functionality in. The customer can choose to delete or add less important functionality at any time and thus tune his functionality/time-to-market opportunities.
• The result is solid control of development projects, faster results, better quality, less stressed developers and happy customers, providing maximised economy.
