You want to release all the time inside your building. You need the feedback, to watch the product grow.
Some of my clients have said, “But my customers don’t want the software that often.” That might be true. You may have product constraints, also. If you are working on a hardware/software product, you can’t integrate the software with the hardware either until the hardware is ready or that often.
I’m not talking about releasing the product to the customers. I’m not talking about integrating the software with the hardware. I’m talking about small, frequent, fully functional releases that help you know that your software is actually done.
You don’t need hardening sprints. Or, if you do, you know it early. You know you have that technical debt now, not later. You can fix things when the problem is small. You see, I don’t believe in hardening sprints.
Hardening sprints mean you are not getting to done on your features. They might be too big. Your developers are not finishing the code, so the testers can’t finish the tests. Your testers might not be automating enough. Let’s not forget architectural debt. It could be any number of things. Hardening sprints are a sign that “the software is not done.” Wouldn’t you like to know that every three or four weeks, not every ten or twelve? You could fix it when the problem is small and easier to fix.
Here’s an example. I have a number of clients who develop software for the education market. One of them said to me, “We can’t release all the time.”
I said, “Sure, you can’t release the grading software in the middle of the semester. You don’t want to upset the teachers. I get that. What about the how-to-buy-books module? Can you update that module?”
“Of course. That’s independent. We’re not sure anyone uses that in the middle of the semester anyway.”
I was pretty sure I knew better. Teachers are always asking students to buy books. Students procrastinate. Why do you think they call it “Student syndrome”? But I decided to keep my mouth shut. Maybe I didn’t know better. The client decided to try just updating the buy-the-book module as they fixed things.
The client cleaned up the UI and fixed irritating defects. They released internally every two weeks for about six weeks. They finally had the courage to release mid-semester. A couple of schools sent emails, asking why they waited so long to install these fixes. “Please fix the rest of these problems, as soon as you can. Please don’t wait.”
The client had never released this often before. It scared them. It didn’t scare their customers. Their customers were quite happy. And, the customers didn’t have all the interim releases; they had the planned mini-releases that the Product Owner planned.
My client still doesn’t release every day. They still have an internal process where they review their fixes for a couple of weeks before the fixes go live. They like that. But, they have a schedule of internal releases that is much shorter than what they used to have. They also release more often to their customers. The customers feel as if they have a “tighter” relationship with my client. Everyone is happier.
My client no longer has big-bang external releases. They have many small internal releases. They have happier customers.
That is what I invite you to consider.
Release externally whenever you want. That is a business decision. Separate that business decision from your ability to release internally all the time.
Consider moving to a continuous delivery model internally, or as close as you can get to continuous delivery internally. Now, you can decide what you release externally. That is a business decision.
What do you need to do to your planning, your stories, your technical practices to do so?
