Writing Technical Manuals For Maintenance Procedures

Klaus has been with the company for 31 years. He designed the original control system. He knows why every design decision was made. He knows which tolerances matter and which ones are just legacy numbers nobody questioned. Klaus retires in April. When I asked the engineering manager what they’d done to capture Klaus’s knowledge, she said: “He’s been meaning to write some things down.” “Some things.” 31 years of institutional knowledge. “Some things.” This is the most expensive knowledge loss in manufacturing, and it happens every single quarter at companies across Germany. The documentation team’s role isn’t just writing manuals. It’s being the institutional memory of the organization. Here’s the framework we use for proactive knowledge capture: → Structured interviews (not “tell me everything”—specific questions about specific decisions) → Decision logs (why was this designed this way? what alternatives were considered?) → Process documentation (not just what to do, but what to watch for and why) → Video walkthroughs of complex procedures (30-minute sessions, not Hollywood productions) → Validation sessions (have the departing expert review what was captured) Start 6 months before the retirement date. Not 6 weeks. The knowledge walking out the door is worth more than the pension walking in. #KnowledgeManagement #TechnicalWriting #Manufacturing #Documentation

Documentation that ships today needs to work tomorrow. But complete docs can become unmaintainable when they're built without a maintenance plan. Here are 6 ways technical writers build for the long term: 1. Write Modular Content That Updates Independently → Break docs into standalone topics → One update fixes all instances → Future writers don't need full system knowledge 2. Document the "Why" Behind Decisions, Not Just the "How" → Future writers understand what to preserve → Decisions get questioned when they no longer make sense → Documentation evolves with product 3. Build Reusable Components Instead of Duplicating Content → Change once, update everywhere → No hunting for duplicated content → Reduces conflicting information risk 4. Create Update Triggers Tied to Product Changes → Writers know exactly what needs updating → Changes get caught before users notice → New writers know what to check 5. Design Information Architecture That Scales With Growth → New content fits without restructuring → Users find information as system expands → Avoids expensive reorganization later 6. Establish Version Control That Tracks What Changed and Why → Mistakes can be undone → Change history shows patterns → Compliance requirements met automatically Completion gets docs shipped. Maintainability keeps them working. That's not perfectionism. That's sustainable documentation. Which approach saves you the most maintenance time?

Firms waste money when they hire technical writers and then use them like formatting support. Yes, formatting matters. Grammar matters. Professional presentation matters. But that is not the strategic value of a technical writer. A good technical writer is looking for the place where the reader is going to misunderstand the instruction, skip the warning, choose the wrong form, miss the deadline, abandon the process, or call three people for an answer that should have been in the document. That is not cleanup work. It is risk reduction. Aviation and aerospace figured this out a long time ago. Those industries became so concerned about misunderstanding, maintenance errors, and translation problems that they developed controlled technical language standards for documentation. One of them—ASD-STE100 Simplified Technical English—restricts vocabulary, sentence structure, and ambiguity in technical instructions. Not because pilots, mechanics, or engineers are incapable of understanding complexity. Because people under pressure misread things. They skip steps. They interpret wording differently. They work while tired, distracted, overloaded, or translating information across languages. At some point, the industry realized unclear writing was not just an inconvenience. It was operational risk. That is the part many organizations still miss. A procedure is not successful because it exists. It is successful when someone can use it correctly at the moment it matters. In healthcare, unclear discharge or medication instructions can send someone home with the wrong understanding of what to do next. In accessibility work, I see this constantly. A form can be “available” and still unusable. Instructions can be present and still fail. A PDF can look finished while the tag structure makes it miserable—or impossible—for someone using assistive technology. None of that is just formatting. It is what happens when information was published before anyone asked, “Can a real person complete the task with this?” Technical writers ask that question. They test the logic. They find the missing context. They catch the buried assumption. They notice when the structure does not match the way the work actually happens. If your technical writer spends all day fixing fonts, spacing, and commas, your organization is wasting a strategic role. Because good technical writing is not cleanup after the work. It is part of how the work becomes usable. Caption: Good documentation assumes humans will be human.

Most maintenance work instructions are written poorly. They’re too long, too complex, unclear, lacking detail, and written by engineers who never have to use them. As a result, technicians can't find the information they need to effectively and efficiently do a job. Worse, they do the job without following the work instructions. One way to make sure your work instructions are clear and effective is by using Simplified Technical English (STE). Here are some rules from the STE that you can apply: 1. Avoid long noun clusters ❌ Remove the engine transmission housing attachment bolts. ✅ Remove the bolts that attach the transmission housing to the engine. The second version is a little longer but much clearer. 2. Use clear, specific verbs ❌ Test the equipment. → Test how? What exactly should they do? ✅ Do a resistance test on the equipment. The more specific you are, the less room for error. 3. Keep sentences short ❌ If there is excessive wear on the brake pads, replace them with new ones that match the manufacturer's specifications before reinstalling the assembly and torquing to the correct value. ✅ Check the brake pads for wear. If they are worn, replace them. Use the correct specification. Torque to the correct value. Shorter sentences results to faster comprehension and fewer mistakes. 4. Be consistent with terminology Replace = install a new part of the same type. Change = install a different type of part. Different words mean different things, and inconsistency can lead to errors. That means you don’t “change” an oil filter—you replace it. Better Work Instructions = Better Maintenance When work instructions are clear, concise, and easy to follow, maintenance gets done faster and with fewer errors. A lot of organisations struggle with this. But you don’t have to. Watch our free lesson video on creating work instructions that work! Link in the first comment. #maintenance #reliability
