'''Adaptive software development''' ('''ASD''') is a [[software development process]] that grew out of [[rapid application development]]the work by [[Jim Highsmith]] and Sam Bayer on [[rapid application development|rapid application development (]]RAD). It embodies the principle that continuous adaptation of the process to the work at hand is the normal state of affairs.

Adaptive software development replaces the traditional [[waterfall model|waterfall]] cycle with a repeating series of ''speculate'', ''collaborate'', and ''learn'' cycles. This dynamic cycle provides for continuous learning and adaptation to the emergent state of the project. The characteristics of an ASD life cycle are that it is mission focused, feature based, [[Iterative and incremental development|iterative]], [[Timeboxing|timeboxed]], risk driven, and change tolerant. As with RAD, ASD is also an antecedent to [[agile software development]].

The word ''speculate'' refers to the [[paradox]] of planning – it is more likely to assume that all stakeholders are comparably wrong for certain aspects of the project’s mission, while trying to define it. During speculation, the project is initiated and adaptive cycle planning is conducted.
