The foundation for a successful project implementation is good planning. Typically, in a planning process, elements will emerge that can either be categorized as decisions, activities or risk. The planning work should be structured around the decisions that are necessary for the project to reach its goal. Decisions are the driving force of any project. Decisions drive the project forward. A decision will depend on other decisions. These dependencies must be documented as part of the planning process. Decisions are made at different levels in the project organization. Some decisions are made by the project employee alone, others are made by the project manager and others must be made by the project owner / customer. Identifying who will make which decision is therefore an important part of planning. For each decision, the decision basis must be described. The decision basis will be one or more data objects (notes, spreadsheets, presentations and drawings) that will be made available to the decision maker.
