Why documentation is worth the effort
Writing instructions often feels like a distraction from the real work. In practice, a clear article can answer the same question dozens of times without anyone’s time being spent. It also protects the team: when the one person who knows how something works is away, good notes keep things running.
Documentation has a cost, though. A poor article that is wrong, vague or out of date can be worse than none, because people trust it and follow it. The goal is a small number of accurate, readable pages that people actually use.
Start with the reader
Before you write, decide who the article is for and what they are trying to do. A guide for end users who want to connect to wireless networking needs plain words and screenshots. A runbook for an administrator restoring a service can assume more background but must be exact.
Ask:
- What will the reader already know?
- What problem brings them to this page?
- What should they be able to do when they finish?
Write for someone who is a little stressed and in a hurry, because that is often the case when people reach for documentation. Take the guidance on technical communication seriously: short sentences, familiar words and no unexplained acronyms.
Pick one purpose per article
An article that tries to explain a concept, give a procedure and cover every exception is hard to follow. Keep each page to one job. Common types include:
- How-to: steps to complete a task.
- Troubleshooting: symptoms and likely fixes.
- Reference: facts people look up, such as settings or contact details.
- Explanation: background on why something is done a certain way.
- Policy or standard: what is required; these often belong with formal IT policies instead.
Linking between related pages is better than merging them into a long document.
Use a consistent structure
Consistency helps readers find things quickly. A simple structure for a how-to article might be:
- Title that states the task, such as “Set up email on a phone,” not “Mobile email information.”
- Summary: one or two sentences on what the article covers and who it is for.
- Before you start: requirements, permissions, and anything the reader should have ready.
- Steps: numbered, in order.
- Expected result: how the reader knows it worked.
- If something goes wrong: the most common problems and what to do.
- Who to contact and when the page was last reviewed.
Reusing the same template across pages means readers know where to look and writers do not have to reinvent the layout.
Write good steps
Steps are the heart of a how-to. A few rules improve them dramatically:
- One action per step. “Open Settings and select Network and then choose Wi-Fi” is three actions. Splitting it reduces mistakes.
- Start with a verb. “Click Save,” “Type your username,” “Restart the computer.”
- Name things exactly as they appear on screen, in bold or a distinct style, and mention where to find them.
- State the result of a step when it is not obvious. “A confirmation message appears” lets readers check they are on track.
- Put warnings before the risky step, not after. If a step deletes data, say so first.
- Avoid unexplained shortcuts like “configure as usual.” What is usual to you is not usual to the reader.
Screenshots help but go out of date quickly when software changes. Use them where they clarify something difficult, crop them to the relevant area, and keep the text clear enough to work without them. For longer processes, a short training video may help, but it needs the same maintenance, and written text is easier to search and update.
Be careful with sensitive information
Documentation is often widely accessible. Do not paste passwords, keys or personal data into articles. Point to where credentials are held, for example in an approved password manager, and describe how to request access. Mark internal-only pages clearly and restrict access to sensitive ones. If a page describes security procedures, share it only with those who need it.
Make it findable
A perfect article nobody can find is no use. Choose titles that match the words people use, which may differ from your internal names. Include common synonyms in the text, and add tags or categories if your system supports them. Look at the search terms users actually try in the help desk or portal, and check that they bring up the right articles. Where an organization offers self-service portals, a well-organized knowledge base is a large part of what makes them work.
Test the instructions
The most reliable way to find problems is to follow the article exactly as written, ideally on a clean device or test account. Better still, ask someone unfamiliar with the task to try it while you watch silently. Every place they hesitate or ask a question is a place to improve the text.
Common faults found this way include missing prerequisites, steps in the wrong order, assumed knowledge, and instructions that differ from what the software now does.
Keep it current
Out-of-date documentation is a common failure. A few practices help:
- Assign an owner to each article or group of articles.
- Show the review date and set a regular reminder to check.
- Update after changes. When a system or procedure changes, updating the related pages should be part of finishing the work. Linking this to change management helps make it routine.
- Archive or delete articles that are no longer true, rather than leaving them to mislead.
- Invite feedback. A simple “Was this helpful?” or a comment option shows where problems are.
Resolved tickets are a good source of new material. If you solve something and it is likely to recur, spend ten minutes turning it into an article. The same applies to the help desk, where the pattern of repeat questions shows what to write next.
A short before-and-after
Weak: “Set up the VPN as normal and connect. If it fails, check your settings.”
Better:
- Open the VPN app from the Start menu.
- In the Server box, type the address provided in your welcome email.
- Sign in with your work username and password.
- Select Connect. The status should change to “Connected.”
If you see “Connection failed,” check that you are online, then try again. If the message remains, contact the help desk and mention the exact text shown.
The second version names the starting point, gives each action separately, states what success looks like and says what to do next. That is most of what good documentation consists of.
