We can see that scope creep leads to the problems with the customer.
Next, it impacts the project scope, budget and in many cases even a timeline. It impacts all the tree general project KPIs.
As a result it puts a shade on your relationships with the client. What is more, you could be considered as a not reliable and not professional manager.
It could be even worse if the scope creep was not caught by the project manager during the scope verification and was addressed by the client as a product error.
Definitely, scope creep is something we do not welcome on projects.
To sum it up, scope creep is something that was implemented on the top of the project scope without approval and that is passing by the change management process.
