Process where delivery of a product results from repeated cycle of development activity.

Each execution of the cycle yields a result successively closer to desired outcome.

• Identify what they need to achiever in this iteration
• Plan how they are going to do it
• Evolve the products in question in accordance with their plan
• Review the outcome with a view to determining whether another iteration is required

Control needs to demonstrated, & recommends using:

• Timebox control; recommends  three iterations: Investigation, Refinement, Consolidation
• Timebox Review Records; which should be kept under formal configuration management to provide audit trail of how product evolved
• Daily standups. Brief. Discuss progress & what to do if anything is blocking progress
• Solution Review Records (optional), form basis for tracking issues, also need CM 

• SDT, provided they can demonstrate control,  are expected to left to get on with their work.
• Management by exception
• Solution Foundations with agreed scope & priorities, & properly defined Acceptance Criteria should form basis for control
