Deploy Your Current Build

At the end of a successful iteration you should consider deploying your final working build for the iteration into one or more environments. For the sake of simplicity we call this your iteration build. As described in Chapter 15 there are several environments that you will consider deploying your working builds into. Note that you may have chosen to deploy into some of these environments during the iteration too. These environments are as follows:

  • Demonstration. Most teams deploy their iteration build to their demonstration environment in time for the iteration demo.

  • Pre-production testing. Some DAD teams, particularly those in regulatory or complex situations, have a parallel independent test team supporting them. A common practice is to make your iteration build available to this team.

  • Production. You may decide to deploy into production at this point. This decision may be made as the result of a specific milestone review, because the release date for your solution has come up (some DAD teams work under hard deadlines), or because it’s common practice to release regularly into production. The appropriate milestone—milestones are described in greater detail in Chapter 20, “Governing Disciplined Agile Teams”—would be the “Sufficient Functionality” milestone. In lean parlance this is often referred to as the Minimally Marketable Release (MRR) decision point, which we find to be quite a mouthful. The purpose of the milestone is to determine whether the additional value provided by this release exceeds the costs of deployment and that the new functionality in the release is sufficiently consumable by the end users. There are several approaches, described in the next section, for coming to this decision.
