If you’ve ever spent hours deciphering someone else’s cryptic configuration, or frantically tried to recall that one crucial step you performed months ago, you’ll understand the silent agony of poor (or non-existent) documentation. Just like overthinking can stall our progress, the lack of clear documentation can cripple our teams and hinder our individual growth.
In the world of IT, whether we’re on the front lines of helpdesk support, managing critical infrastructure, building automation pipelines, or writing integrations, it’s easy to prioritise doing over explaining. We troubleshoot, we fix, we deploy, and we move on. Documentation often feels like red tape, a slowdown we can’t afford.
But what if documentation isn’t a burden? What if it’s a force multiplier i.e, a way to increase the value of the work we’ve already done?
Good documentation isn’t about writing War and Peace for every single task. It’s about creating clear, concise, and easily accessible resources that help ourselves and our colleagues understand:
What was done: The exact steps taken to configure a system, resolve an issue, or implement a change.
Why it was done: The reasoning behind decisions, the context of the problem, and the intended outcome.
How it was done: The specific tools, commands, and configurations used.
Where to find it: A centralised and organised system for storing and retrieving information.
Creating documentation isn’t about perfection, it’s more about clarity, consistency, and actionability. The flow below outlines a practical approach I use to create high-impact, team-friendly documentation.
Documentation can take many forms:
Knowledge base articles.
How-to guides.
Workflows.
Troubleshooting guides.
Release notes.
Onboarding/Off-boarding processes.
User manuals.
Infrastructure diagrams and playbooks for operations teams.
The key is to tailor the format and depth to suit the audience and purpose without compromising clarity.
Just as analysis paralysis can stem from a desire to “get it right,” the reluctance to document can sometimes come from a feeling that “it’s faster if I just do it myself.” While this might be true in the short term, it creates significant long-term risks.
One of the most critical benefits of thorough documentation is its ability to mitigate the risk of a single point of failure. Imagine a scenario where only one person on your team knows how to troubleshoot a critical system or perform a key deployment. What happens when that person is unavailable due to illness, vacation, or a change in employment?
Suddenly, the team is scrambling, productivity grinds to a halt, and stress levels skyrocket. This is where documentation acts as a vital safety net. By clearly outlining processes and solutions, we empower the entire team to:
Troubleshoot independently: When issues arise, well-documented procedures allow other team members to diagnose and resolve problems without relying solely on the “expert.”
Onboard new team members efficiently: Comprehensive documentation provides a valuable resource for new hires to quickly get up to speed on systems and processes.
Maintain consistency: Documented standards and procedures ensure that tasks are performed consistently, reducing errors and improving reliability.
Share knowledge and learn from each other: Documentation becomes a living repository of team knowledge, fostering collaboration and continuous learning.
Reduce reliance on tribal knowledge: Tacit knowledge held only by individuals is a significant risk. Documentation helps to codify this knowledge and make it accessible to everyone.
Like many, I used to view documentation as a necessary evil. It felt time-consuming and often got pushed to the bottom of the priority list. However, after experiencing firsthand the chaos and frustration caused by a lack of documentation, I’ve come to see it as an indispensable part of effective IT practice.
I’ve started making a conscious effort to document as I go, even for seemingly small tasks. I’ve also championed the creation of a centralised knowledge base for my team. The initial investment of time has already paid dividends in terms of reduced support requests, faster troubleshooting, and a more resilient team.
It’s time we shift our perspective on documentation because it’s an investment in our collective knowledge, our team’s resilience, and our own future success.
Just as we challenged ourselves to embrace “comfortable incompletion” in the pursuit of progress, let’s commit to embracing consistent and clear documentation. It’s a simple yet powerful way to prevent bottlenecks, empower our colleagues, and ensure that the knowledge we gain doesn’t walk out the door with any single individual.
Start small. Document one key process this week. Share your knowledge. You’ll be surprised by the positive impact it has on yourself and your team.🙂
