Practice: Risk-Value Lifecycle
The Risk-Value Lifecycle practice supplements the Iterative Development and Two-Level Planning Practices with the Unified Process Lifecycle. This lifecycle identifies four phases, each of which attempts to balance value provided against risk mitigation appropriate to the phase.

Purpose

Why Adopt this Practice?

Project stakeholders look for ways to understand and control project funding, scope, risk exposure, value provided, and other aspects of the project. While project iterations deliver product increments that show value delivered and show progress at a fine-grained level (i.e., work items being addressed), they do not provide the necessary project oversight, transparency and steering mechanisms at a coarse-grained level that allow stakeholders to make informed business decisions about the project.

The organization of iterations into a set of phases - with a well defined milestone at the end of each phase - provides the structure stakeholders and management need to assess if the objectives of the phase have been met, and if the project should move on to the next phase or not. See Phase Milestones for more details. 

By addressing the goals and risks of each phase, the team has the opportunity to find the right balance between risk reduction and immediate value creation, which are two major stakeholders' drivers. See Project Lifecycle for more information.

How to read this practice

How to Read this Practice

The best way to read this practice is to first familiarize yourself with its overall structure - what it is in it and how it is organized. 

Start with understanding what phases are and how they relate to iterations. Understand what phase milestones mean, and the questions they help answer. See Phase Milestones for more information. You may also read the definition for each phase for more detailed information: Inception Phase, Elaboration Phase, Construction Phase, and Transition Phase.

Then, understand the importance of a structured lifecycle in driving two main stakeholders' concerns: risk reduction and value creation. See Project Lifecycle for more information.

For instructions on how to adopt this practice, see How to Adopt the Risk-Value Lifecycle Practice.
