Managing Stage Boundaries is one of seven processes that make up PRINCE2, a systematic approach to project management developed by the UK's Office of Government Commerce and used widely in UK government and industry.
The fundamental principle of Managing Stage Boundaries (SB) is to ensure that, at the end of each stage, the project stays focused on delivering business benefit.
Managing Stage Boundaries (SB) is one of seven processes outlined by PRINCE2.
The process involves reviewing the current stage (is the business case still valid, should we proceed to the next stage[1]), preparing for the next one, and selecting information which can be of use later in the project.
If the Project Board is satisfied with the current stage end and the next stage plan, the project is permitted to continue.
