Organizations that implement ITIL practices can do much more than increase the efficiency of release processes; they can also realize financial gains and increase the business value of the services they offer. Enterprise release management ERM manages the big picture of releases at the organizational level of entities with large or complex software, such as healthcare systems, big companies, universities, and the like. Why is this important? Imagine an organization that develops complex systems of software.
Multiple development groups work on different components of these large systems. This structure makes sense internally because it allows developers to specialize, increase focus, and build components piece by piece. But, ultimately, the pieces must converge in a single, seamlessly integrated system.
ERM enables organizations to roll out large software products that work well as an integrated whole, and it helps them to do this efficiently. ERM efforts typically call for many release managers to work in tandem, so they can synchronize their respective releases. In a paper presented at the Project Management Institute Annual Seminars and Symposium, Franck Aguilh discussed the emerging realization among software development companies that there was a need for a specialized discipline that focuses exclusively on managing releases.
The release manager rather than the project manager would play this role, as the project manager has much more expansive priorities. Aguilh said that successful release management is a process that attains four main objectives: deploying on time, deploying on budget, having negligible impact on existing customers, and meeting the requirements of new customers, all while keeping in mind competitive pressures and technological advancements.
Release management calls for coordination between many departments within an organization, each of which fulfills a specialized role. QA must perform checks. Operations must manage branches and get the build ready for deployment. But those are just the technical components. Each organization has different communication preferences. Meetings, a chat channel, a Wiki page, or just email are all good ways to keep people in the loop. These include the main project management process areas: initiating, planning, executing, controlling, and closing.
However, Aguilh also posited nine processes that are specific to release management. Following are descriptions of these nine processes as well as the order in which they occur:. Aguilh suggested that the processes of release management correspond quite closely to those of project management. For example, FPR and release packaging are basically a consideration of scope and planning, while quality corresponds to documentation, development, change control, and training.
Executing and controlling, in turn, correspond to training, customer testing, customer notification, and deployment. Closing, of course, maps to deployment. It becomes evident, therefore, that useful parallels can be drawn between project management and release management and that an effective release manager needs to possess the same skills as a project manager.
You have seen how release management processes align with core project management processes. There are typically six phases in the SDLC:. During development, managers lay out a release policy , a document that defines the scope, principles, and end goals for the release management process.
To see an example, take a look at the release policies of the Apache Software Foundation, which promotes open source software projects for public good. Release managers draw up release plans based on the release policy. These plans are broad guidelines for deploying multiple releases. During the design phase, the release manager makes sure the hardware and software assets that will support the release are designed and configured.
Then, coding begins. During implementation, the developers build and configure the code. During testing, testers try out the code in an operational environment. During deployment, the staff rolls out a live version of the software, and the quality assurance team conducts a quality review to see that the release meets its stipulated requirements.
If the release passes the quality review, it is validated and slated for production; this seal of approval is referred to as release accepted. If bugs remain, the team will reject the release. An accepted release has a rollout plan that covers the details of deployment, and the company informs clients and end users about the upcoming release.
Training may be necessary. The release units are deployed to production for full launch. Some organizations choose to verify the implementation at this stage in order to ascertain whether the release will run smoothly when live. In the maintenance stage, developers conduct a review of the release and log issues to be resolved for the next release. To make the timeline clear for all your release activities, create a release management schedule. Use this template to track key deliverables and deadlines to keep everyone on the same page.

It is intended for an audience beyond developers, either others in the organization or customers. A release generally carries a version number. When a customer deploys a release, it is generally described as an installation of the software. Shipping describes the process of getting code through the entire building, testing, and deployment loop. Deployment is a crucial juncture in both the software development life cycle and the release management cycle. Deployment marks the moment when the new software version is available for use and the new release goes live.
Jackson notes that deployment is often problematic: More than 50 percent of commissioned software is not used, mostly because it fails at deployment. Jackson also reports that 80 percent of the spending on commissioned software occurs at and after deployment. But sometimes, deployment is the problem.
Relying on best practices in release management makes these solutions standard operating procedure. The release deployment process is focused on making the software operational in a live environment. For this to occur, the software must go through testing and be officially accepted by the product owner or another business stakeholder. During the deployment process, users receive training on the software update, and team members conduct an assessment or review of how it is performing and how deployment went.
In release management, best practices are the guidelines created and refined by companies that have already implemented ITIL with success. The guidelines are owned and published by the British Cabinet Office. ITIL release management processes have been used with good outcomes by space programs, health services, banks, and entertainment companies. The guidelines must be modified by organizations to meet their own requirements and capacities. Remember, though: These are a starting framework, not a gospel.
Although release management matters most during the transition from development to production, it starts with the planning of releases during development. Similarly, creating a release process checklist encourages transparency as well as shared understanding of the release management process and how it creates business value. In addition, it helps to have an active senior sponsor. In the medical community, checklists save lives. To keep track of all your release activities, consider using a checklist.

Continuous integration, for example, improves the quality of the eventual release by catching errors quickly. Another option is a staged rollout in which features are made available only to a small number of users at a time. And, of course, databases need to be backed up before releases. Lastly, remember that implementing a release management process is a process in itself.
Release management can be iterated and automation achieved a little bit at a time. After a release is triggered and completed, you may want to email the summary to stakeholders. Use the Send Email option on the menu that opens from the ellipses In the Send release summary mail window, you can further customize the information sent in the email by selecting only certain sections of the release summary.
The names of releases for a release pipeline are, by default, sequentially numbered. The first release is named Release-1 , the next release is Release-2 , and so on. You can change this naming scheme by editing the release name format mask. In the Options tab of a release pipeline, edit the Release name format property in the General page. DefinitionName creates releases with names such as Release for build You can customize how long releases of this pipeline must be retained.
For more information, see release retention. Every time you save a release pipeline, Azure Pipelines keeps a copy of the changes. This copy allows you to compare the changes at a later point, especially when you're debugging a deployment failure. The computation for the first bullet is as follows for a build: Let's say, for example, that you started a new build.
Whatever the setting, we compute a list of new commits for the build. We do the following tasks:. It could happen that there's no last known successful build on the same branch. For example, when you run a build for the first time on a branch, or when all the previous builds on a branch have been deleted possibly through retention policies. The list could be long in these cases.
Once we have the list of commits, we enumerate all the work items associated with each of those commits.
This is the list that you see in a build. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Is this page helpful?

Note This article covers classic release pipelines. Ever wondered, why softwares generally have a 4 decimal identification number in their About dialogs. What do these 4 decimal digits signify? Lets have a look, closely. Generally, the Version number is a 4 decimal number something like 7.
These numbers signify :. Major: The first part of the 4 decimal number of the version, represents the number of Major releases a sofware has gone through. The first ever release of any software to the world will have the Major number 1 no candies for guessing. This will only be incremented in case of a Major overhaul to the product like:.
