Initiation and Planning activities occur at the beginning of a project.
A project may be for the creation of a new product, or the enhancement of an existing product. It may even involve the merging of capabilities from multiple products into a new, more capable product. It is always necessary to have an understanding of what the outcome of the project is. This is often called the High Level Requirements. These requirements set direction for the project. Once the direction is set, an early activity is the Make, Buy or Reuse decision.
