Scope statements define the boundaries of a project, specifying what is within and outside the scope. Completion Criteria outline what constitutes successful phase completion and deliverable characteristics. Constraints are limitations such as resource limits, time constraints, and budget restrictions. Dependency Linkages highlight inter-project dependencies and information gathering processes. Impacts describe organizational changes, retraining, and operating budget fluctuations. Measures of Project Success identify metrics to measure success. Assumptions outline circumstances and events that must occur for the project's success. The Work Breakdown Structure (WBS) is a hierarchical chart that breaks down work into small, manageable tasks. Project Controls encompass data gathering, management, and analytical processes to predict, understand, and constructively influence time and cost outcomes.
