Product Development – planning a minor / dot release – Challenges

In the last post, I had talked about why a minor (dot) release is needed, as well as some of the reasons as to why doing a dot release is an inconvenience. However, if the decision has been made to do a dot release, then it is necessary to understand the process of planning and executing a dot release, including some of the difficulties (challenges) that emerge in such a minor release.
What are some of the activities that need to be done ?
1. You need to finalize the changes that need to be a dot release. If this release is because of some known changes, then the changes need to be analysed, and the engineering response (and design) needs to be worked out.
2. If the changes are still unknown, for example, if your release is failing some security tests or some certification, then you need to figure out what can be done. If you take an example where the earlier release is failing some new certification norms (and for those who know how certification works, it can be a lot of effort to prepare the infrastructure and execute all the cases. As an example, you may need to take the help of tools for certification, and those tools may need an upgrade of memory. In other cases, the amount of testing required may be huge, and the actual calendar time needed may stretch the schedule of the dot release.
3. For companies where a lot of work is handled by support teams (configuration, build, release, internationalization, etc), the required overhead of handling all those teams and getting their support takes both budget allocation and time.
4. Too many minor releases causes cynicism in the market about the initial stability of the software release. For example, Microsoft releases many service packs for its software, and there are many people who do not migrate onto a newer version until they see 1 or 2 service packs because they would rather wait for some of the important bug fixes.
5. You run into issues where there are multiple releases for around the same version (with say versions 8.0, 8.1, 8.2, etc for a product). Once you have multiple versions, you get into support issues whereby issues are different for these versions, and support may be a nightmare.
6. Newer dot versions, in many cases need to be deployed to the retail channel (replacing the software already in the retail channel), and to the web store (including to many online software sellers who resell the software). All of these steps involve huge logistical nightmares and / or costs.
7. Branching strategies. Getting a dot (minor release) in process needs major configuration issues (getting branches in place, especially when work is also going for the next release), and takes a fair amount of explanation to both the Development and Quality teams.

Of course, if you folks can suggest more issues that make minor releases a challenge, please add comments.
