When developing large systems a specialist project manager or even a team of project managers will be appointed to perform project management tasks. All projects require project managers; for small projects a single individual may develop the system and also take on the role of project manager.

Successful project managers possess excellent communication and planning skills. They must motivate the development team, negotiate with all stakeholders, resolve conflict and at the same time ensure the project progresses within budget and time constraints. A variety of different project management tools are available to describe and document the various techniques that will be used to manage the project.
