Control
There are several methods to control feature creep, including: strict limits for allowable features, multiple variations, and pruning excess features.
Temptation of later feature creep may be avoided to some degree by basing initial design on strong software fundamentals, such as logical separation of functionality and data access. It can be actively controlled with rigorous change management and by delaying changes to later delivery phases of a project.
Another method of controlling feature creep is to maintain multiple variations of products, where features are kept limited in some variations. Because the ever-growing, ever-expanding addition of new features might exceed available resources, a minimal core "basic" version of a product can be maintained separately, to ensure operation in smaller operating environments. Using the "80/20 Rule" the more basic product variations might support the needs of about "80%" of the users, so they would not be subjected to the complexity (or extra expense) of features requested by the other 20% of users. The extra features are still available, but they have not crept into all versions of the products.
At some point, the cost of maintaining a particular subset of features might become prohibitive, and pruning can be used. A new product version could simply omit the extra features, or perhaps a transition period would be used, where old features were deprecated before eventual removal from the system. If there are multiple variations of products, then some of them might be phased out of use.

Famous quotes containing the word control:
“For the mother who has opted to stay home, the question remains: Having perfected her role as a caretaker, can she abdicate control to less practiced individuals? Having put all her identity eggs in one basket, can she hand over the basket freely? Having put aside her own ambitions, can she resist imposing them on her children? And having set one example, can she teach another?”
—Melinda M. Marshall (20th century)
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
“Have we any control over being born?, my friend asked in despair. No, the job is done for us while were sleeping, so to speak, and when we wake up everything is all set. We merely appear, like an ornate celebrity wheeled out in a wheelchair. I dont remember, my friend claimed. No need to, I said: what need have us free-loaders for any special alertness? Were done for.”
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
