Every workplace has that one person who “just knows how things work.”
Need to deploy a feature? Ask them.
Need access to a system? Ask them.
Need to understand why a process was set up a certain way three years ago? Ask them.
At first, this seems efficient. The team relies on experience and informal knowledge. People help each other when questions come up.
But the moment that person goes on vacation, changes roles, or leaves the company, things suddenly slow down.
Questions pile up.
Processes become unclear.
And small tasks start taking much longer than they should.
What looked like efficiency was actually a lack of documentation quietly waiting to cause problem.
When New Team Members Have to “Figure Things Out”
Poor documentation becomes especially visible when someone new joins the team.
Imagine a new analyst starting their first week. They’re excited, motivated, and ready to contribute.
They open a project folder expecting to find a guide explaining how reports are generated or how data flows through the system.
Instead, they find scattered files and outdated notes.
So they start asking around.
One colleague explains part of the process. Another remembers something slightly different. Eventually, the new hire pieces things together through trial and error.
What should have been a smooth onboarding experience turns into several days of guesswork.
This is not a competence issue. It’s a documentation issue.
The Hidden Productivity Drain
The biggest problem with poor documentation is not the occasional confusion. It’s the time that disappears every week because information isn’t written down.
Think about how often teams answer the same questions repeatedly:
“How do we run this report again?”
“Where is the latest version of that document?”
“Who approved this workflow originally?”
Each question might take only five minutes to answer.
But multiply that across a team and across weeks, and suddenly hours of productivity are lost simply because knowledge was never captured.
Documentation Is Not Busy Work
Some teams treat documentation as optional or something to do “later.”
But well-written documentation is actually a time-saving tool.
A simple guide explaining how a process works can prevent dozens of repeated explanations. A clear project note can help future team members understand decisions instantly.
Good documentation turns tribal knowledge into shared knowledge.
Final Thoughts
Documentation may not feel exciting, but its absence is often felt immediately.
When processes are clearly written down, teams move faster. New employees onboard smoothly. Questions decrease. Work becomes easier to maintain.
In the long run, documentation isn’t extra work.
It’s the quiet system that keeps everything running smoothly.
