The MECE principle suggests that to understand and fix any large problem, you need to understand your options by sorting them into categories that are:
Mutually Exclusive – Items can only fit into one category at a time and
Collectively Exhaustive – All items can fit into one of the categories.
MECE helps to break down the complex problem into smaller, non-overlapping units which overall constitutes the complete problem. We can then proceed with the analysis of the individual subproblems and further apply MECE if possible.
