Acceptance criteria are essential for defining what success looks like for a project. They should include not only the traditional measures of success such as being on time, on budget, and within scope but also the specific benefits and performance improvements expected by the sponsor and stakeholders, such as cost reduction and system response time improvements. If these criteria were not accurately defined or documented, it can lead to misunderstandings about what constitutes a successful project completion. Properly defined acceptance criteria ensure that there is alignment between the project team and stakeholders (including the sponsor) regarding project outcomes. If these criteria were not clear or comprehensive, the project team might believe they have met their objectives based on scope, time, and budget, while missing critical performance or benefit targets important to the sponsor.
