All the teams are fully independent and they work separately on the different projects. The
structure is quite simple and all the employees reports to one person
In this model there are dedicated managers/leaders for each main specialization, "renting" their people for particular projects led by product/project managers, who formally or informally buy the people and pay for their time. This leads to each private employee having two bosses – the product/project manager and the specialized "resource" manager. On one hand it optimizes the usage of human resources, on the other hand it may give rise to conflicts about which one manager has priority in the structure.
There are also a number of variants of these structures, and a number of organizations have this structure spread and split within various departments and units.
