The pairing session we were engaged in wasn't yielding positive results. We were attempting to resolve a complex bug but were met with frustration at our lack of success. The most disheartening part for me wasn't the stagnation itself but the underlying cause of our struggle.
During my time as an observer, I noticed that my teammates were having significant difficulty getting their code to run locally. They lacked a reproducible method to debug the application within their IDEs and had resorted to scattering print statements throughout the code. Their tests were unreliable, often failing without warning, which exacerbated the situation. To complicate matters, they were grappling with a chaotic array of Docker containers and managing four terminal windows, each overflowing with text.
Our inability to progress stemmed from our struggles to run or debug the application effectively in isolation. The code was accessible yet felt out of reach.
This scenario highlights a critical issue: the codebase had not received adequate attention towards enhancing the developer experience.
In this discussion, I aim to explore the concept of Kaizen and how we can consistently enhance our developer experience. I won't introduce any groundbreaking techniques, as many already exist. Instead, I wish to emphasize the importance of prioritizing daily work improvements and provide actionable steps to begin this journey.
Chapter 2: The Vital Nature of Daily Improvements
I was captivated the first time I read The Phoenix Project. I finished the book in under a week, which is impressive for someone like me who reads slowly. The characters and situations felt incredibly relatable, to the point where some passages were hard to digest.
Upon reading The Unicorn Project, I experienced a similar yet even more intense reaction. Author Gene Kim masterfully articulated every challenge I had faced throughout my development career! I found myself cheering (perhaps vocally) as Maxine skillfully navigated the intricate landscape of code and organizational politics.
These books, among others, have profoundly influenced my perspectives on organizational dynamics, experimentation, and various developer-centric concepts. However, the most significant takeaway for me was the understanding that the most crucial task for developers is the enhancement of daily work.
Gene's "Three Ways" and "Five Ideals" encapsulate much of this message more eloquently than I could. My interpretation is that any improvement made to the ease of contributing code to a team's codebase will yield cumulative benefits over time.
For instance, a mere 5% enhancement in your ability to contribute code today results in a 5% improvement for the entire team tomorrow. This 5% boost paves the way for further advancements in developer experience in the coming weeks and beyond.
Whether it's addressing technical debt or automating environment setup through tools like Make or Ansible, every improvement accumulates quickly.
Improved Developer Experience Leads to Superior Code
When developers encounter challenges in contributing code swiftly and safely, a series of negative outcomes can unfold. Tests may be skipped due to their complexity, teams may find themselves repeatedly rewriting similar code because of poor structure, and individuals may hesitate to make even minor changes for fear of introducing bugs. Over time, these patterns create a downward spiral: the team struggles to contribute effectively, leading to stagnation in improvements. The code deteriorates as no one actively maintains or enhances it, making subsequent changes even more daunting.
Conversely, investing in the enhancement of daily work yields a positive cycle. When tests are straightforward to create, teams can focus on writing reliable tests and executing them regularly. Reusable patterns are recognized and abstracted, allowing for efficient coding. Confidence in making changes grows as developers trust the tests and the code, knowing it will highlight any oversights.
This virtuous cycle results in easier daily modifications, better code, quicker product delivery, and often fewer bugs in production.
However, facilitating a simpler code contribution process doesn't only benefit the code itself; it significantly boosts team morale.
Improved Developer Experience Leads to Enhanced Morale
The ability to contribute code swiftly and safely extends beyond mere code quality or delivery speed; it enhances team morale. Research, including the SPACE framework, indicates that developers perform best when they find joy in their work. Joy, in this context, refers to a genuine sense of satisfaction and happiness in daily tasks.
When developers take pleasure in their work, it fosters a positive and confident atmosphere within the team.
Consider the all-too-frequent scenario where a team is assigned to deliver a feature within a challenging codebase. With brittle tests, convoluted local environment setups, and minimal documentation, the team may spend the initial weeks merely getting everyone operational.
As the project moves forward and deadlines approach, the difficulties of working within this codebase take their toll. Frustration builds, the pressure of impending deadlines escalates, and soon, the team experiences heightened stress. Developers may become disengaged, exhibit impatience, and adopt a negative outlook. Even the most cohesive teams can struggle under such stress.
Now, imagine how the team might feel if they had been afforded time to enhance the codebase before diving into feature development. They could have addressed brittle tests, automated environment setups, or refactored tightly coupled code sections—perhaps even a combination of these efforts.
In this situation, prioritizing daily work improvements would leave the team feeling empowered and optimistic. They would feel a sense of ownership over the codebase, riding a wave of positive momentum, which in turn elevates overall morale. This positive mindset further reinforces the push for daily work enhancements.
We can fundamentally change how our teams function by bolstering their capacity to write exemplary code.
Chapter 3: Strategies for Improvement
If you recognize the importance of this concept, you may be wondering: "How can I improve daily work?" This is a valid query. Assessing a codebase for potential enhancements can be daunting, particularly when considering where to begin.
Here are some strategies that have assisted me in refining the codebases I've encountered:
Be Observant
Before implementing any improvements, it's crucial to identify the areas in need of enhancement. While the phrase "if it ain't broke, don't fix it" is too extreme, it’s easy to become overly enthusiastic in your quest for positive change. Not every module, class, or command requires refactoring, nor does every step need immediate automation.
You need to pinpoint the leverage points within the code that warrant attention. Observe how you interact with the code: How do you run tests? How do you review automated test results? Are there sections of the code that seem off-limits? Do certain abstractions pose challenges in understanding and utilization?
These observations will guide you toward areas that merit your time and effort. Keep mental notes (or jot them down) about your experiences to identify the most critical focus points.
Reserve Judgment
It’s easy to be a critic when you’re distanced from the matter at hand. Whether it’s politics or sports, it’s simple to voice opinions from a safe space. This tendency can extend to codebases as well. When examining the code, we may quickly spot flaws and criticize the developers behind them, thinking, "Why would they do it this way?"
To foster progress in improving the developer experience, we must withhold judgment, especially when joining a new team. Instead of criticizing the current state, strive to understand the decisions and forces that shaped the code's evolution. Codebases undergo numerous transformations as the products they support change; these transitions can be abrupt or rapid, compelling teams to adapt swiftly.
Such transformations may create peculiar "gaps" in the code that need bridging to ensure functionality. It's akin to a house with too many hasty additions, resulting in a disjointed layout filled with gaps and cracks.
Gaining context helps us appreciate that while the code may exhibit issues, it once served a purpose. Approaching the code with this mindset enables us to ask better questions about its future direction rather than making arbitrary changes to address immediate problems. Ironically, those ad-hoc changes often contribute to the very issues we encounter.
By withholding judgment, we can gain a clearer understanding of how to enact meaningful changes.
Start Small
Once you've identified areas for improvement, you may be eager to jump in. However, caution is essential. Large-scale refactors and comprehensive rewrites often lead to failure, frequently due to their sheer size.
Instead, focus on making incremental changes. Even creating an npm script for a commonly performed task can yield significant benefits (no more sifting through terminal history). Although these adjustments may seem minor in the grand scheme, small victories accumulate, producing a compounding effect.
By concentrating on smaller enhancements, you can seamlessly integrate these efforts with your regular tasks. This way, you won’t require special permissions to address something that only takes a few hours to implement. Additionally, as you weave improvements into your daily work, you'll uncover further areas for enhancement. You might only discover an unusual API for a class through regular engagement with the code.
Of course, some changes will demand more deliberation, planning, and time. In these instances, estimate the impact of your proposed enhancement on the code and the developer experience. Aim to articulate a clear rationale for "Why this?" and "Why now?" While you may not provide a precise dollar value or time estimate, pointing to delayed projects, outages, or ongoing on-call stress can serve as compelling justifications.
Involve Others
Lastly, ensure you bring others into the fold. Invite your teammates to envision the potential of a transformed environment. Engage them in your initiatives and exchange ideas collectively. Assist them in visualizing the benefits of collective effort.
When approached correctly, this collaboration will reveal additional areas for improvement and generate offers of assistance. People are motivated to contribute when they perceive a meaningful impact. Discover what your team values and collaborate to bring those ideas to fruition.
Not everyone will be on board, of course. Skeptics and cynics exist in every team and can pose challenges to progress. While it's crucial not to dismiss them outright, you also don't want them to hinder the team's enthusiasm.
From my own experiences, I've discovered several effective approaches:
- Do Not Dismiss Them: Avoid ignoring dissenting voices. Neglecting this behavior can foster tension within the team.
- Find Common Ground: Even if they disagree with the majority of your proposals, focus on areas of agreement. By building rapport, you’ll understand each other's positions better and find opportunities for collaboration.
- No Need for Consensus: It’s unnecessary to achieve consensus on every change. If one person consistently disagrees while the rest support an idea, proceed with it. This should not be done spitefully; rather, it’s about making progress despite differing opinions.
The key takeaway is clear: integrate the enhancement of daily work into your routine.
It may require some experimentation to find the right approach, and you may need to persuade other developers to participate, but this work is critical for teams striving for success.
Ultimately, it’s the most vital contribution we can make as developers: empowering our peers to become more effective.
