Book excerpt: INTRODUCTION Whether we are the apprentice, an ambulant vendor, in the market or on a proximity display, we are nourished with the same intention to earn what we need to afford a meal, the maintenance of an individual, a couple or of a family. Everything begins with the need of household income that lead to informal entrepreneurship. At the favor of historic influences and heritages, external economic models were imposed to Africa and in numerous third world countries. This is done not taking into account the popular realities, if it is not acknowledging the powerlessness to integrate the dynamism of the informal economy into the schemas of the governance of states. The two systems have been coexisting for long now without really seeing the transition of the informal to be an alternative to the dominant and oppressing model of the market economy which serves as an actual reference. Can we however envision that this transition is done by the autonomous development of the informal to become a quality revenue sharing framework? The first step is without a doubt to familiarize yourself with the characteristics of this sector and then to identify its dynamic to finally present a model accessible to all and simply applicable without necessitating a real academic curriculum. The present analysis therefore permits to have a first look from the outside, as much as possible, by taking a step back.
