Infrastructure Refactoring


the change per a standard Agile iteration. At the end of the iteration, the project team and product owner decides if the infrastructure change is acceptable and ready to go live into the working infrastructure and start being used by the project team. If not the change can be bundled with the deliverables of next iteration(s) and then released together.


Work the IPAIR Loop

The next strategy in approaching the changes is to consider the steps that will help you through an iteration focused on establishing or changing infrastructure. Because it is less likely that there will be a fully dedicated infrastructure team assigned due to the multi-tasking nature of infrastructure work, we want to keep the steps fairly simple and consistent. Also infrastructure professionals may not be into Agile as much as the project team, so a simpler variant of the traditional iteration is suggested. In this case, consider an IPAIR approach or something similar:

·         Identify changes and place in infrastructure backlog

·         Prioritize changes

·         Assess impact of changes

·         Iteratively make the changes

·         Re-assess impact of change seeking approve and release of changes

·         Begin the loop again (e.g., rinse, then repeat)

The steps within the iteration should be brief and simply enough to follow. The changes that are identified should be small enough that they can be made within the 1 week iteration. If you encounter a situation where you need more than one week, be flexible enough to expand the iteration timeframe. Also, you may find that if it is a larger change, that there may be a way to break up the change into smaller chunks of work to fit a short iteration.
