7. EDGE™ Clarify the Problem Decompose or divide a complex problem into simpler problems that can more easily be solved in a focused manner.Decompose or divide a complex problem into simpler problems that can more easily be solved in a focused manner. Several “decomposition” methods available, such as:Several “decomposition” methods available, such as: –Sequence of User Actions –Key Customer Needs –FUNCTIONS, known as Functional Decomposition Division process occurs until sub-functions can be worked on easily Function diagram useful for documenting but they are not unique; several decompositions may be found for a given problem A simple list of sub-functions (without connections shown) is also acceptable
