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:
““Have we any control over being born?,” my friend asked in despair. “No, the job is done for us while we’re 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 don’t remember,” my friend claimed. “No need to,” I said: “what need have us free-loaders for any special alertness? We’re done for.””
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
“Time in the hand is not control of time,
Nor shattered fragments of an instrument
A proof against the wind; the wind will rise,
We can only close the shutters.”
—Adrienne Rich (b. 1929)
“All industries are brought under the control of such people [film producers] by Capitalism. If the capitalists let themselves be seduced from their pursuit of profits to the enchantments of art, they would be bankrupt before they knew where they were. You cannot combine the pursuit of money with the pursuit of art.”
—George Bernard Shaw (1856–1950)
