PRINCE2 (Projects in Controlled Environments) sets out project management guidance for all types and sizes of projects, and it has become a de facto standard used extensively by the UK government as well as widely recognised throughout the private sector both in the UK and internationally. This publication explains the PRINCE2 methodology, with practical guidance on project management designed to ensure projects are managed effectively to achieve business benefits within budget, within time and to the required quality, and which offers a flexible approach to suit all projects. This publication can also be used as a study guide for the theory requirements of the PRINCE2 Foundation examination.
