Definition according to DIN 69900: The detailed network plan is a network plan whose structure allows an insight into many details of the project sequence. It is developed from the general network plan by increasing the roughly executed events, activities and their relationships while retaining the process structure, e.g. by refining several activities of the general network plan on the basis of a subnetwork plan. The early activities are considered first, followed by the later ones as the project progresses. A detailed network plan can replace or supplement the general network plan. In the latter case, the two plans must also be coordinated during the project. (Source: GPM)
