Enjoying technical debt
2022-05-08
Introduction
I've found a method to help me enjoy working on technical debt. This method helps me to be more productive and motivates me to do my other work. I'll share it with you here.
Where does technical debt come from?
Technical debt can come in many forms. You will commonly hear that technical debt comes as a result of taking shortcuts when building software. This is certainly one place where technical debt comes from.
Shortcuts
In a perfect world we will never take shortcuts when designing software. Unfortunately time is a valuable resource! Sometimes shortcuts when building software can be necessary to quickly demonstrate concepts. After the concept is demonstrated to stakeholders we need to make a decision: continue using the concept code (ignore the tech debt), or replace the concept code with a long-term solution (pay down the debt).
The software industry has no shortage of euphemisms for shortcuts: proof of concept and 'demo code' are common. We even have a name for engineers who do this type of work often: rockstars!
Sometimes shortcuts are necessary. The organization you find yourself in may dictate how often you take shortcuts. For example, an organization where there is a strong vision and agreement between parties may not require many shortcuts - the emphasis is on delivering a good solution to customers. In an organization that doesn't value being thorough or one that isn't as focused on a shared vision you may find yourself taking more shortcuts to convince others of your idea.
Technical debt can be used as leverage. We only have a finite amount of time to build software. Choosing to take on technical debt by taking a shortcut means we are essentially borrowing time from the future to achieve our goals sooner. This can be incredibly valuable! After all, there is an infinite amount of time in the future that we can use as leverage, and the time before the next demo is certainly finite!
Low priority tasks
Some work just isn't a priority, so it ends up languishing in the backlog. Every software project I have seen has an infinitely growing backlog. Software can always be improved! This is another popular place for tech debt to grow.
This form of tech debt is what we will discuss in this blog post. I see the growing backlog as a pile of pleasure, not a mountain of pain!
Addressing technical debt
Participants in a software project tend to see technical debt as a weeping sore. It's something that bothers us and makes it harder to make progress. Many of us have participated in discussions with product owner explaining that progress is slowing down because of tech debt.
Common methods
I've experience a number of ways that organizations attempt to pay down tech debt:
- Tech debt sprints. All feature work is paused for two weeks while tech debt is addressed.
- Tech debt hackathons. Feature work is paused for a day while tech debt is addressed. This might happen between sprints, on a quarterly basis, or on some other interval.
- Allocating time to address high priority tech debt. During sprint planning some tasks are taken by the team to pay down tech debt.
- Rewriting the software. In one organization all of the software was rewritten every few years. Can't have tech debt if the software ceases to exist!
My recent attempts
Recently I have been trying something else: dedicating up to an hour per day to unprioritized work of my choosing. This provides many benefits to me and the team.
Autonomy
I choose which tasks I take on. Nobody asked me to do this work, so I feel that it is a great opportunity to choose how and when I perform these tasks.
Mastery
I use this time to learn new things. Rather than taking on work that is familiar to me I will take on a task that will allow me to learn a new tool or learn a new area of the system.
Purpose
Taking on this work not only makes me feel good due to the previous two points, but it helps me to make others on my team more productive. This pays dividends! The best way to succeed is to make sure your project succeeds, and one way to do this is to enable your coworkers to do good work.
Increased productivity
When I am working on a difficult problem I often find it benefitial to stop and focus on something else for a short time. This allows my subconcious to continue chewing on the problem while I do something else. Paying tech debt is a productive break from critical work.
The playbook
Choose the work
I prefer to choose small tasks. Preferably the task can be completed in a few hours of work. Taking an hour per day to work on this means that I have submitted one 'bonus' change each week. This is a great motivator that makes me feel even more productive.
If the work you want to take is large, see if you can break it up into small pieces that each deliver value. For example, if you've always wanted to make a version of your service that relies on no external dependencies (maybe useful to make testing easeir), see if you can start by adding a trait/interface for interacting with one external dependency. If you lose motivation for your long term goal at least you have made testing one module easier.
Make the time
I start some mornings by dedicating an hour to this type of work. Starting my morning with learning something new of my choosing helps me to look forward to work each day. Dedicating mornings to this work makes it easier to allocate the time. Let's think about the opposite case: you crunch through critical work for most of the day and then try to jump to non-critical work. This is not a good model for me. I find that my brain is still intensely focused on the high priority work and I cannot concentrate on learning the necessary concepts to accomplish the low priority task.
Strictly time box
It is important to strictly time box this work, both in the micro (up to one hour each day) and in the macro (if your one-hour increments add up to 40 hours you should consider if the task can be made smaller). This is unprioritized work, after all. We should always be focused on helping our team succeed. Often this means spending your time working on high priority tasks.
Conclusion
I've had great success following this model recently. I may go a month without doing this work, or I may dedicate an hour each day for a month to unprioritized work! I am happiest when I make the time to do what I outlined here.
