What Is a Change?
A change is any deviation from the previously approved baseline plan. It can impact the project’s key constraints: schedule, scope, and cost, as well as quality and stakeholder satisfaction. Ideally, a change affects only one of these elements, but in reality, it often influences all of them.
For example, consider a project with a two-month timeline and a budget of $10,000. The client requests an additional task, which extends the project by two weeks and increases the cost by $3,000.
Once the new timeline and budget are approved, the project's baselines are updated, incorporating the additional work into the scope. As a result, the schedule extends to 2.5 months, and the cost baseline increases to $13,000. In this case, all three baselines—scope, schedule, and cost—have changed.
This is why change management is called integrated: modifying one baseline often leads to adjustments in the others. Modern project management software, such as Microsoft Project, links these baselines together, ensuring that a change in one automatically updates the others. This functionality makes change management much more efficient.
