Within chapter 1 of the PMBOX Guide, it states that within a project life cycle, there are generally one or more phases that are associated with the development of the product, service, or result. These are called a development life cycle. Development life cycles can be predictive, iterative, incremental, adaptive, or a hybrid model. 

In my experience with medical device development, I have worked on projects mainly with a predictive developmental cycle. However, due to its poor project management, it ended up having more of a poorly planned hybrid lifestyle.

What are your experiences with the different types of developmental life cycles? How have they worked -or not worked- for you, teams you have led, or teams you have been on?
