I hope it is of interest for architecture students and professionals who always likes to work in an organized manner, and with a scientific method. We will reflect the revision of some of the following criteria-based: Central Idea of what is a (weighted) functional compatibility matrix: means compatibility matrix functional, to the set of activities, that analyzed with each other can be determined that relate between them form:-very strong. -Strong. -Weak. Other architects considered that these activities are correlated as:-very strong.

-Strong. -Moderately strong – weak. According to this type of comparison, you can establish a relationship of each activity, to see with which relates: very strong, strong, moderately strong or weak. To thus get to apply the formula of Kussan which States that: R + V = A + 2. If we get by experience in the realization of this type of matrix, it would be good to explain some of our forms of analysis to undertake a project. Primary: for us it is the work itself, or the repertoire, which may well be: a housing, a hotel, a cafeteria, etc., but that we know first of all answer these questions: u what kind of work is? u what to do within its walls, and what was being done outside its walls? u How can I vary those activities inside of its walls, and the outside? u what the main activity that is done in it, and what or which activities other activities generated me to your around, to declare them hierarchical – activities poles most important activities? u how each of these activities within the premises, as work there your operators, and how you want to operate the premises? Only after knowing the essence of what we want to project, and above all its operation, it is that we will be able to carry out an array of functional compatibility.
