Project management processes. These processes ensure the effective flow of the project throughout its life cycle. These processes encompass the tools and techniques involved in applying the skills and capabilities described in the Knowledge Areas.
Product-oriented processes. These processes specify and create the project’s product. Product oriented processes are typically defined by the project life cycle and vary by application area as well as the phase of the product life cycle. The scope of the project cannot be defined without some basic understanding of how to create the specified product. For example, various construction techniques and tools need to be considered when determining the overall complexity of the house to be built.
The PMBOK® Guide describes only the project management processes. Although product-oriented processes
are outside the scope of this document, they should not be ignored by the project manager and project team. Project
management processes and product-oriented processes overlap and interact throughout the life of a project.
For instance, in software development projects, the product-oriented processes may include requirements gathering, analysis, design, coding, integration, testing, implementation and training. These are unique to the software development projects type and the methodology used (RUP, SCRUM, Agile, XP, Waterfall).
