Mutually Exclusive Collectively Exhaustive. – Barbara Minto
MECE is the way to break down a work item into several more detailed tasks. It has two main principles: the first is integrity, which means that one item should not be left out in the process of decomposition, and the second is independence, which emphasizes the independence of each work. There should be no overlap between each task.
Deficiencies:
- Reticular structure
- dynamic analysis
