The always bigger specialization of the companies increases the decline of the general-purpose know-how.

To solve problems which are not of their competences, companies are more and more using study offices, themselves always more specialized and thus called to subcontract the ancillary know-how of their speciality.

The Aissor concept is born from this growing demand of the companies as well as local governments that are subcontracting a lot today.

Aissor is neither a client nor a subcontractor, but it partially substitutes itself to each.
Aissor is a general-purpose know-how, the ideal project manager to create an effective link between the need of some and the means of others.
