We’re Doing More Less Development

My roots are in software development. I’ve written tax software, SmartGrid firmware and servers, enterprise integration code for many developed and purchased servers, mapping software, cell phone firmware—the list goes on. The point is development is in my blood. When I look at something that impacts software development, I look at it through a practitioner’s lens as much as an analyst’s. And there is a lot of change going on in the realm of software development.

For a very long time, there have been options out there that reduce the amount of software we develop. And those options are often popular. There was a time where the most common phrase in enterprise IT was “Develop core systems, purchase support systems,” and the message sank in enough that we don’t need to say it anymore. There was a time when enterprises cobbled together systems as essential as email–some developing their own systems, but most working hard to integrate available offerings. We have completely flipped that equation, and now almost no one would consider spending significant IT resources on email. Not on development, not on integration. There are of course corner cases that do have to–our industry could be defined as a collection of sharp-corner cases we haven’t yet smoothed out–but few, if any of those reading this blog have had to worry about those corners. So, change number one: Purchasing IT solutions is massively successful at reducing our time. From CRM to email to security, we’re using far more tools written by others.

There have also been code-generation tools forever. While the most well-known ones have historically been UI-focused, 4GLs generally tried to address development with less code. Again, time, failures and iterations have given us useful code-reduction techniques. From pre-formatted ‘if’ statements that we just plug in variables to API generation through (sometimes AI-powered) initial program generation engines that give us code to start a project. The requirements for writing code are less per-project.

And the big one: Open source. There are entire software markets for which it isn’t worth developing solutions because there are good open source solutions on the market. If it is popular but even vendors cannot afford to make solutions because everyone is using the OSS solution—well, that reduces the amount of code developed. There are several companies whose entire business model is simply offering enterprises service and support on OSS. No development required, even for the “vendor.” Large portions of any given application we develop these days are based on open source that we include to solve one piece of the problem. We’ve had some spectacular hacks and failures based upon that model, but it is undeniably an enabler for more solutions.

With all of these (and arguably more–like API-first and API standardization) reducing the amount of code we’re developing, you would think developers would be less busy, right?

DevOps and Agile streamlined our development and shortened delivery timelines for subsets of a given project, but haven’t—and weren’t designed to—reduce the amount of software developed. Indeed, quite the opposite. With faster iterations, more could be tried out.

But it is wrong to think there is less development effort. There are several reasons for this, but I’m going to focus on the big one. People invested in the company—business leaders, etc—have always had a massive pent-up desire to improve software to increase efficiency, competitiveness, etc. And IT was the bottleneck. Agile/DevOps are by no means perfect, but they offered a pressure release valve for that pent-up demand. And we’ve been at it long enough to know that rapid iterations in response to those demands inspire more new ideas, creating another iteration… So it will be unlikely to stop. Indeed, we all know what technical debt is, but there seems to be a disconnect between knowing intuitively that more code means more debt in the form of maintenance overhead. So developers are doing more because the organization has good ideas that need implementation, even though we have plenty of tools to reduce development effort. Some organizations have reduced developer headcount, but not many. And that might slow, but that’s unlikely. In the coming highly competitive environment, more features and solutions will be desired, not less.

And you’ll be there, continuing to rock it. Pay attention to ways you can further reduce code effort. This is a long-term process, but the goal should be to reduce the growth rate in staff time. It is unlikely to go down overall–because maintenance overhead plus new projects is a constantly growing number–but slowing growth helps developers and working managers stay sane and take the time to find good hires.

And just keep doing more less development.
