All activities, work packages, subtasks and events with their respective planned dates are combined into an implementation plan which, after all the usual coordination and approval processes, forms the legal basis for the implementation of the project. All persons involved in the project must be familiar with the plan in its entirety or, if the scope is too large, with the relevant parts of it. The further planning documents of the project should be developed from this implementation plan, e.g. the time-related cost, expenditure, financing documents, as well as the resource planning.
