Structuring Engineering Documentation

If You Don’t Write It Down, It Doesn’t Exist If someone solves a production issue and no one can find the fix later, was it ever really solved? That’s the problem. Engineering teams are full of solved problems with no paper trail. Someone fixed it. Someone probably explained it in a meeting. Someone might have even dropped a brilliant note in Slack. And now it’s gone. ⸻ Here’s what “write it down” actually means: • A runbook that says do this, not that, with timestamps, alerts, and real outcomes • A postmortem that includes what broke, what fixed it, and what you’d never do again • A PR comment that explains the why, not just the diff • A dashboard saved with a name like “CPU spike on bad deploy,” not “test123finalfinal” • A searchable place to put it all that people can actually find when they’re tired and paged at 2 AM If it’s not searchable, it’s not documentation. It’s trivia. ⸻ Why does this matter? Because production doesn’t care who solved it last time. • If it’s not written down, the next engineer starts from zero • If it’s buried in a random channel or Notion page 14 clicks deep, it doesn’t help • If the title is “debug_notes_final_(copy)_v3,” no one’s opening it • If it lives only in one person’s brain, that person just became the team’s single point of failure Meanwhile, searchable, useful documentation: • Cuts incident resolution time • Keeps on-call engineers sane • Prevents Slack archaeology • Builds shared understanding across time zones and roles • Turns one solved problem into 10 avoided ones ⸻ Good documentation is like a GPS during an outage. Bad documentation is like a pirate map written in invisible ink. Make it short. Make it useful. Give it a name someone would Google. Documentation should reduce pain, not require a scavenger hunt. If the problem was worth solving, it’s worth writing down. If it’s written down, make sure it’s findable. If it’s not findable, guess who’s getting paged again?

The difference between a good design doc and a great one is usually clarity. Technical writing should be crisp and to the point. So, it is always better to treat every sentence like it has a cost. After writing, cut aggressively. Remove extra words. Then check if a line can go. Sometimes even a full paragraph is unnecessary. One thing I always do is to start the doc with the conclusion; this way, the reader/reviewer knows where we are heading. This is contrary to how most engineers write docs - listing every approach first and only concluding at the end. That slows readers down. I avoid this because long explanations make people lose track; most readers want the conclusion quickly. So, always start with the answer and why it matters. Then add details and alternatives below for those who want depth. A habit that helps is a quick editing pass like this: - Remove filler words and repeated ideas. - Break long sentences into smaller ones. - Prefer bullets when listing options or steps. - Check if the first section clearly states the outcome. - Add a link or short explanation where a reader may pause. Empathy matters more than most people realize. Try to read your document as someone new to the topic. Ask yourself what might confuse them. Add the missing context. Add the helpful link. Let the ideas evolve naturally from problem to solution. This skill develops over time. Use simple language and fewer buzzwords. The goal is to communicate, not impress. Simple documents get read more. More readers means better alignment and better visibility for the work. Finally, always provide enough context. A short setup about the problem, constraints, and prior decisions goes a long way. It helps readers understand why the decision exists, and, of course, it prevents unnecessary back and forth later. Hope this helps.

The Medical Device Iceberg: What’s hidden beneath your product is what matters most. Your technical documentation isn’t "surface work". It’s the foundation that the Notified Body look at first. Let’s break it down ⬇ 1/ What is TD really about? Your Technical Documentation is your device’s identity card. It proves conformity with MDR 2017/745. It’s not a binder of loose files. It’s a structured, coherent, evolving system. Annexes II & III of the MDR guide your structure. Use them. But make it your own. 2/ The 7 essential pillars of TD: → Device description & specification → Information to be supplied by the manufacturer → Design & manufacturing information → GSPR (General Safety & Performance Requirements) → Benefit-risk analysis & risk management → Product verification & validation (including clinical evaluation) → Post-market surveillance Each one matters. Each one connects to the rest. Your TD is not linear. It’s a living ecosystem. Change one thing → It impacts everything. That’s why consistency and traceability are key. 3/ Tips for compiling TD: → Use one “intended purpose” across all documents → Apply the 3Cs: ↳ Clarity (write for reviewers) ↳ Consistency (same terms, same logic) ↳ Connectivity (cross-reference clearly) → Manage it like a project: ↳ Involve all teams ↳ Follow MDR structure ↳ Trace everything → Use “one-sheet conclusions” ↳ Especially in risk, clinical, V&V docs ↳ Simple, precise summaries → Avoid infinite feedback loops: ↳ One doc, one checklist, one deadline ↳ Define “final” clearly 4/ Best practices to apply: → Add a summary doc for reviewers → Update documentation regularly → Create a V&V matrix → Maintain URS → FRS traceability → Hyperlink related docs → Provide objective evidence → Use searchable digital formats → Map design & mfg with flowcharts Clear TD = faster reviews = safer time to market. Save this for your next compilation session. You don't want to start from scratch? Use our templates to get started: → GSPR, which gives you a predefined list of standards, documents and methods.

𝐒𝐭𝐚𝐤𝐞𝐡𝐨𝐥𝐝𝐞𝐫𝐬 𝐚𝐬𝐤𝐞𝐝 𝐲𝐨𝐮 𝐭𝐨 𝐝𝐨𝐜𝐮𝐦𝐞𝐧𝐭 𝐫𝐞𝐪𝐮𝐢𝐫𝐞𝐦𝐞𝐧𝐭𝐬. 𝐍𝐨𝐰 𝐰𝐡𝐚𝐭? As a Business Analyst, this may sound simple, but it’s where clarity and alignment are absolutely critical. Before diving into documentation, remember: 📌 Not all requirement documents are created equal. Each organization—and often each project—has its own format, naming conventions, and compliance needs. So instead of rushing to create a BRD, SRS, or FRD, pause and follow this structured approach: ✅ 1. Clarify the Purpose First Ask: – Who is going to use this document? – Why do they need it? (e.g., approval, development, testing, audit) – Is it for business, technical, or regulatory use? ✅ 2. Confirm the Document Type & Template – Does the organization follow any format? – Is there a repository of approved templates (Confluence, SharePoint, Jira, etc.)? – Should it be a Business Requirement Document, Functional Spec, User Story format, or Use Case model? 💡 Don’t assume—always ask the stakeholders. ✅ 3. Align with the Audience – Use business language for business stakeholders – Use structured, testable formats for QA & developers – Include traceability for auditors and compliance ✅ 4. Structure the Requirements Clearly A good structure usually includes: 🧩 Business Objective 📊 Scope (In/Out) 👥 Stakeholders 🔧 Functional Requirements 🛠 Non-Functional Requirements 🔗 Dependencies & Constraints 📎 Assumptions 🧪 Acceptance Criteria ✅ 5. Get Buy-in and Iterate Don’t treat documentation as a one-time task. 🎯 Share drafts early 🔁 Gather feedback in rounds ✍️ Keep versions controlled 📣 Great documentation doesn't just record what’s needed—it drives clarity, collaboration, and confident delivery.

MDR Annex II: Ultimate Guide for Organizing Your Technical Documentation Missing crucial regulatory strategies is like building a skyscraper out of paper. There will be a result, but it will not meet expectations. Here is one of my paper-skyscraper experiences: I underestimated how important it is to properly organize a Technical Documentation. Back then, my folders were chaotic—mixing risk management files, clinical data, and product descriptions without a clear structure. This is where Annex II of the EU MDR comes into play. It provides a clear structure for your technical documentation, breaking it into 6 key chapters. Here’s a breakdown of Annex II and how to use it effectively: 1. Device Description and Specification ↳ Define the device’s intended purpose and classification. ↳ Include key design features and technical characteristics. ↳ Think of this as your product’s “business card.” 2. Information to Be Supplied by the Manufacturer ↳ Includes all device labels for single-unit, sales, and transport packaging. ↳ Labels must be provided in the languages accepted by Member States. ↳ Instructions for use (IFU) must also comply with language requirements. 3. Design and Manufacturing Information ↳ Describe development and manufacturing processes ↳ Use flowcharts for clarity and simplicity. ↳ Show alignment between production and quality standards. 4. General Safety and Performance Requirements (GSPRs) ↳ Create a checklist linking evidence to Annex I requirements. ↳ Use a matrix to map compliance for each GSPR. ↳ Highlight key tests and documents supporting each claim. 5. Benefit-Risk Analysis and Risk Management ↳ Follow ISO 14971 principles for risk management. ↳ Show links between risks, mitigations, and residual risks. ↳ Document how benefit outweighs any residual risk. 6. Verification and Validation Data ↳ Provide clinical evaluations and performance testing results. ↳ Include usability studies to show real-world safety. ↳ Prove the device works as intended for its purpose. Why Follow Annex II? When a Technical Documentation is well-organized: → Auditors can quickly find what they need. → Your team works more efficiently during submission preparation. → Regulatory delays are minimized, and certification is faster. For my first project, I learned the hard way. Today, I always organize a Technical Documentation based on Annex II’s chapters—and it’s made all the difference. P.S. Are you organizing your Technical Documentation according to Annex II? Or do you follow a different structure? ---------------------------------- MedTech regulatory challenges can be complex, but smart strategies, cutting-edge tools, and expert insights can make all the difference.

A 60 page doc tripled this engineering team's velocity, I've been talking to engineering leaders for weeks, and there's a pattern nobody's discussing yet: teams aren't optimising for better code anymore. They're optimising for better documentation. They went from "we barely document anything" to maintaining a 60-page AGENTS.md file in just 3 months. Not user docs. Not API specs. Business logic documentation specifically for AI agents. These files include coding conventions, business logic, good vs bad examples, testing workflows, and architecture reasoning. What changed? They started using Cursor and Claude Code heavily. They realized something: when AI writes your code, the quality of what it produces correlates DIRECTLY with how well you explain your business logic. The shift is fundamental: Old way: Write code, document later (maybe) New way: Document first, let AI write the code Another team I spoke with now tracks "context quality" as a KPI. They're not measuring lines of code anymore , they're measuring how well their documentation helps AI understand what they're building. The bottleneck isn't coding speed anymore. It's context clarity. For engineering leaders using AI tools: are you seeing this pattern? How are you handling documentation? PS: if you’re a CTO/Engineering leader facing testing bottleneck and interested in shipping 10x faster, let's chat - https://lnkd.in/gJJUET-S

Writing Effective Technical Documents (Part 3): The Four Layers of a Good Technical Document I think about a technical document in four layers. Each layer has a purpose and together they tell the full story. 1. Decision or Executive Summary: Start with the decision or key takeaway. Busy readers should be able to stop here and understand the direction. 2. Context: Give the business and technical background. Business context covers the problem, goals, and success criteria. Technical context covers the current state, key constraints, and assumptions. 3. Implementation Details: Explain the alternatives considered, tradeoffs, and reasoning. Include diagrams or examples if they help. 4. Open Questions and Concerns: List what is still unresolved. Invite input. This makes the document a place for collaboration, not just information. A good document lets readers go as deep as they need without getting lost.

Software Architecture Documentation Good architecture is as much about communication as it is about code. A well-documented architecture bridges the gap between vision and implementation, aligning teams and ensuring longevity for your systems. Software architecture docs are the blueprint for understanding, talking about, and changing a system’s design. It helps teams work together better by keeping track of important decisions and details. Good docs make it easier to scale, debug, and improve the system, plus everyone understands what’s going on. Keep your docs short, useful, and organized (like using ADRs, RFCs, etc.). Think of them as code—always updating. Here are a few ways of writing and managing one: 1️⃣ Architecture Decision Records (ADRs) Every choice in architecture has consequences—technical, operational, and cultural. ADRs provide a lightweight, structured way to document why decisions were made, the trade-offs considered, and the context at the time. They’re invaluable for future teams to understand the why behind the how. 2️⃣ Request for Comments (RFCs) Collaboration is key for a sound architecture. RFCs enable open dialogue by inviting feedback on proposed changes before implementation. They create a culture of shared ownership, making the architecture a living, evolving entity rather than a rigid blueprint. 3️⃣ Event Storming When designing complex systems, especially those using event-driven architectures, event storming helps. By focusing on business events, you uncover hidden domain knowledge, identify bottlenecks, and align stakeholders—technical and non-technical alike. 4️⃣ The C4 Model Clarity is king. The C4 model—Context, Containers, Components, and Code—provides a zoom-in/zoom-out approach to documentation that scales with your audience. Whether you’re talking to a developer or a CEO, the C4 model ensures they see what they need to see. To summarize Architecture documentation is significantly more than mere paperwork; it serves as the crucial bedrock upon which resilient, scalable, reliable and maintainable systems are built and sustained. The proper execution of this process will significantly enhance your team’s ability to work at an accelerated pace, all while ensuring the maintenance of high standards and minimizing the potential for errors.
