A baseline can involve data sets from multiple sources that measure different types of data such as Scope, Schedule, Cost, and Performance:
- Scope Baseline: Used to manage work to ensure proper delivery of the product, service, or result. The Scope Statement and the WBS are used to define the Scope Baseline values.
- Schedule Baseline: Used to measure project pace. It uses the dates and/or durations established by the approved schedule to ensure timely delivery.
- Cost Baseline: Used to determine profitability. This is found by creating a cost estimate for each piece of work in the project, then totaling these estimates at the project level to compare against the actual cost of the work and of the project.
- Performance Baseline: Used to evaluate resources. It pulls together information from scope, schedule, and cost to manage, measure, and evaluate resource performance.
- Change in scope will either impact schedule or cost.
- Change in schedule will either impact cost or scope
- Change in cost will either image scope or schedule
