They cannot shorten those two months, as it is contractually required by their client, and that amount of time is often necessary to check for hardware failures. This team works in four-week iterations, and apart from running this two-month MTBF test, their product is at a truly releasable state at the end of each iteration. Because a single iteration does not usually provide sufficient time to complete enough new functionality to satisfy user or customer desires, the broader concept of a release is introduced.

Or they may discover that a certain type of work is more time consuming than previously thought. The value of the plan may be altered by knowledge the product owner has gained about the desires of likely users. Perhaps, based on feedback from seeing the software from an earlier iteration, the product owner has learned that users would like to see more of one type of feature and that they don’t value another feature as much as was previously thought. The value of the plan could be increased in this case by moving more of the desired features into the release at the expense of some of the lesser-valued features.

Remember that ¤ is the universal, generic currency symbol. 1 shows Boehm’s initial ranges of uncertainty at different points in a sequential development (“waterfall”) process. The cone of uncertainty shows that during the feasibility phase of a project a schedule estimate is typically as far off as 60% to 160%. That is, a project expected to take 20 weeks could take anywhere from 12 to 32 weeks. After the requirements are written, the estimate might still be off +/- 15% in either direction. So an estimate of 20 weeks means work that takes 17 to 23 weeks.
