Right on. I just won a Best Buy drawing worth $1000. Either that or I won a shiny new virus by clicking the link. Hmm...what to do. 2012-08-29
The opinions expressed on this site are my own, and not necessarily those of my employer.
Developing enterprise software is hard work. Bureaucracy. Large teams. Legacy systems. The list of challenges is immense. But enterprise development can also offer tremendous opportunity and reward. It can even be fun! I hope that at some point, you have the opportunity to experience this feeling.
I worked here once. In the exciting enterprise. Working here was different. It was actually exciting. What made it different? Well, it was the process. Exciting process? What’s that? It’s the process that makes software development fun again, productive, meaningful, and satisfying.
So what kind of process is this, you ask? Iterative? Agile? RUP? XP? Scrum? Kanban? Hell no! We never talked process lingo. We didn’t care how agile people thought we were. We didn’t want to get caught up in the bureaucracy and political mayhem surrounding software process improvement. There was work to be done. That’s what we talked about. And then we did what we needed to do to get it done.
Working in the exciting enterprise wasn’t always easy though. It required stamina, determination, and discipline. There were lots of people who didn’t appreciate how we went about our business. We didn’t submit weekly status reports. We didn’t have the Gantt chart. Actually, we didn’t have a lot of things. But we had what we needed. To us, it all seemed like common sense. Of course, we had a very experienced team, and we knew what worked and what didn’t.
Plan driven? Predictive? Estimates? Models? Oh yeah…we had it all. We had a 18 month project road map. It was quite a plan. Took a small group of us about 1.5 days to develop. All on a single spreadsheet. Showed all the major systems that we’d retire right along with the new functionality that was going to come online. Probably could have gotten another three months of project time if we wanted to do more planning. But we had code to write.
Code? But what about the requirements? Yep. Gathered them as we went. And when developers had questions, they asked them. Right to the customers face too. Blasphemy! The business analyst working with the developers. Those BAs were awesome too. They worked real hard to clear any confusion. Made sure developers always had what they needed. And we got ‘em as quickly as we could handle them. A steady stream of requirements flowing in and right back out as an executable piece of software.
Oh sure, it wasn’t always easy. We had lots of important checkpoints along the way to make sure we were on the right track. Weekly checkpoints. Daily checkpoints. Hourly checkpoints. Developers and customers sitting in a room together to see what we’d gotten done the past week. Continuous deployment to an environment where folks could actually use the software. Hourly builds that made sure we never strayed too far from a working system.
I still think about that build. Actually, it was more than a build. It was a piece of frickin’ art. That build was the coolest piece of process I’ve ever seen. It was staged. It was fast. It did pretty much anything we asked it to do. It never got in our way. It just went on it’s merry way, building our system. Hourly. Every hour. Automatically. It was the glue that held the team together as we grew in size from a fledgling crew of six developers to upwards of 100 at times.
We protected that build. When somebody cause it to fail, they’d feel the wrath. Eventually, they all grew to love what it could do. Honestly, what choice did we have if we wanted to ensure we could have weekly checkpoints throughout the process? The only way to pull it off was to emphasize software that works. It always had to work. ALWAYS! Guard the source. The prime directive - software that works!
Now don’t get me wrong. We had documentation. We had lots of documentation. Some of it was pretty nice looking stuff too. But we weren’t afraid to let it go. Let it serve it’s purpose and then move onto what was real important…the source code. What else really matters, anyway? All the pretty documents, models and plans don’t amount to a hill of beans if the source code isn’t provably correct. That was our focus. It was the teams focus. And we guarded that source code very closely.
I look back now. An 18 month project. A team that clicked. Not just a development team. A team. Including the customers. Honestly, we didn’t just build a piece of software, though. We improved the process. We automated it. We optimized it. No, I’m not talking about the software process. I mean the business process! That’s what made it so cool…
