Ask any project manager the reasons why projects fail and one of the reasons cited will definitely be scope creep. But is scope creep really that bad? I don’t think so. Your view of the scope creep will depend on how you manage projects. You can manage projects as a contract or you can collaborate.
I think there will be a scope creep when there is a contract between the solution provider and the consumer. For example, it is notorious in the construction industry. In fact, some contractors want the consumer to change the scope in the middle of the project. That’s their way of making money; it is not like you are going to change contractors in the middle of the project. But if both parties collaborate, then scope creep as a reason for project failure just melts away.
