To do this, BASSETTI has developed TEEXMA® Design Guide. True reference system of rules, good practices, returns of experiences. It makes it possible to simply recycle and structure your knowledge of scattered references, in order to facilitate access by multiple entry points: know what to do by navigating your processes; Know what is known about your products, navigating visually in their decomposition; Knowledge of deficiencies to be avoided, requirements to be met and means of verification.
