1. Teams or individuals working on creating something new
2. Initial stages of unstructured or complex work
Deadlines work best when
1. Individual pieces of work are almost complete and integration is required to give product complete shape
2. Repetitive & well understood tasks that require that extra push to reach the finish line
Summary - When the path is clear deadlines help to reach the finish line fast, on the other hand, if one is discovering the path, deadlines are best avoided.
