5 raisons d'inclure les cas d'usage dans l'analyse business ?
Avant de proposer un business model (BMC) innovant, il faut une "analyse business innovante" (new business analysis) s'appuyant sur les cas d'usage (use case).
Les cas d'usage ont de nombreux autres avantages : participation, engagement, innovation, concensuel, rapide, itératif...
5 raisons d'inclure les cas d'usage dans l'analyse business ?
Nous vous proposons de réflechir et de faire l'analyse business avec un framework rapide qui permet d'aboutir à des solutions globales.
Il y a beaucoup de manière de réflechir, beaucoup de cadre de réflexion... nous avons choisi les USE CASE qui permettent d'aboutir à une MVS (minimum viable strategy). Car avant de proposer un business model (BMC) innovant, il faut une "analyse business innovante" (new business analysis).
Pour arriver rapidement à des solutions utilisables nous nous appuyons sur certains outils déjà bien connus, comme VUCA, Design Thinking, Scrum, TESTandLEARN ...
