The problem has been declared, the team must now describe it. This can be an opportunity for initial brainstorming. The objective: not to be short of details. It’s time to release our first tool: the 5W2H. We must absolutely ask ourselves the following questions: Who is involved, What (what happened), Where did it happen, When, How (in what context, at what point in the process, following what procedure), How much (how much involved) and finally Why (what failure generated the problem).
