Every day more industries and governments are taking the tollgate approach to perform projects with excellence, and one of the reasons is that it was developed specifically to help organizations to choose the right projects, and to perform them right.

The tollgate methodology ensures the organizations the proper translation of business opportunities into successful projects; that is, aligning project objectives with the business needs, and then executing the projects in the most efficient way.

The gates methodology is a process of progressive definition of the project. This process is based on a planned and standardized series of reviews (gates) at the end of each phase. This breakdown in phases or stages, and the normalized control points at each end, is an improvement of the classic approach, where the organizations may have points of control but they are not as standardized as the ones that this technique offers.
