Meaning
Uncontrolled expansion of requirements occurs when the boundaries of a task extend without a corresponding increase in resources. This scope creep usually happens through the addition of small features or secondary goals that were not part of the initial plan. The expansion continues until the project either fails or a new boundary is firmly established.
It stops when the project is delivered or canceled.
Goal Drift
Minor changes in direction gradually move the project away from its original purpose. While scope creep may seem harmless at first, the cumulative effect of these additions is a large increase in the complexity of the work.
Resource Exhaustion
Adding new tasks without increasing the budget or the team size drains the available capacity. The cost of scope creep is felt in the dilution of focus and the exhaustion of the people trying to meet the expanded requirements. Each new demand reduces the hours available for the core objectives, which puts the entire timeline at risk.
Boundary Maintenance
Protecting the original definition of the work is a continuous administrative task. The prevention of drift depends on the rejection of any requirement that lacks a corresponding increase in resources or a reduction in existing tasks.
