5. Our advice
As you will have gathered, the number of parameters taken into account in the study correlates with the number of contradictions that will result. In this example, only three contradictions are highlighted, whereas an exhaustive study could have produced around fifty. So be aware that the time you decide to allocate to the problem formulation phase will be correlated to the number of parameters included in the study. It's up to you to choose the parameters involved in the contradictions with care.
The syntax used to express the parameter is important, as it will determine the equivalence with the matrix's generic parameters (see Solving a problem using the Technical Contradiction Resolution Matrix
