I agree with jb678. I feel that it’s easier to control creep in some projects rather than others. For example, mirroring a manufacturing facility is easier than building one from scratch. Yet, there are always going to be issues that arise. Having strong plans and documentation to ensure that what needs to get done, and only what needs to get done, happens is the best way to stay in control. No more no less. In your case, your organizational structure may help or hurt. I have no idea what it’s like for you. Proper planning should be the best way to counteract creep.
