Documenting System Requirements

Let’s be honest — most Business Requirement Documents (BRDs) are boring to read. From my experience, what I have learned is - a good BRD is not about length, it’s about clarity. Here are a few practical lessons (and battle scars) that helped me write BRDs: 1️⃣ 𝐒𝐭𝐚𝐫𝐭 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 “𝐖𝐡𝐲”, 𝐧𝐨𝐭 𝐭𝐡𝐞 “𝐖𝐡𝐚𝐭” Before listing requirements, make sure you’ve answered one thing clearly — 👉 Why does this project even exist? Example: Instead of saying “We need a new payment module”, write — “Customers are dropping off at checkout due to failed card transactions. The new payment module aims to reduce failure rate by 25%.” Now the reader knows the purpose, not just the feature. 2️⃣ 𝐓𝐞𝐥𝐥 𝐚 𝐒𝐭𝐨𝐫𝐲, 𝐍𝐨𝐭 𝐚 𝐃𝐮𝐦𝐩 𝐨𝐟 𝐑𝐞𝐪𝐮𝐢𝐫𝐞𝐦𝐞𝐧𝐭𝐬 Use simple sections that flow logically: 👉 Business Problem 👉 Objectives 👉 Stakeholders 👉 Scope (In and Out) 👉 Functional & Non-Functional Requirements 👉 Dependencies 👉 Risks Each section should answer a stakeholder’s question. For example, “Scope” answers — what are we building (and what are we not)? Keep your reader oriented. 3️⃣ 𝐊𝐞𝐞𝐩 𝐑𝐞𝐪𝐮𝐢𝐫𝐞𝐦𝐞𝐧𝐭𝐬 𝐓𝐞𝐬𝐭𝐚𝐛𝐥𝐞 Never write vague requirements like — ❌ “The system should be user-friendly.” ✅ “The system should allow users to submit a form in less than 3 clicks.” If QA can’t test it, it’s not a good requirement. 4️⃣ 𝐔𝐬𝐞 𝐑𝐞𝐚𝐥-𝐋𝐢𝐟𝐞 𝐄𝐱𝐚𝐦𝐩𝐥𝐞𝐬 𝐚𝐧𝐝 𝐒𝐜𝐫𝐞𝐞𝐧𝐬𝐡𝐨𝐭𝐬 If you’re describing a workflow, include a small diagram or wireframe. If you’re defining data, include a field table. A visual breaks monotony and builds shared understanding instantly. 5️⃣ 𝐀𝐯𝐨𝐢𝐝 𝐂𝐨𝐩𝐲-𝐏𝐚𝐬𝐭𝐞 𝐒𝐲𝐧𝐝𝐫𝐨𝐦𝐞 Every BRD should reflect the voice of that business — not the last project you worked on. Change the language, the examples, and the KPIs to suit your stakeholder’s context. 6️⃣ 𝐕𝐞𝐫𝐬𝐢𝐨𝐧 𝐄𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 You’ll thank yourself later when you have to compare V1.2 with V1.4. A simple version control and approval table saves chaos when sign-offs start flying around. 7️⃣ 𝐄𝐧𝐝 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 𝐈𝐦𝐩𝐚𝐜𝐭 End your BRD with a crisp statement like — “Once implemented, this feature will reduce manual effort by 30%, improve data accuracy, and cut processing time from 2 days to 4 hours.” That’s the line that gets executives to nod. If your BRD can’t be understood by someone outside the project in 10 minutes, rewrite it. Because clarity is the ultimate sign of good business analysis.

Still using BRDs in 2025? Not always. But in the right projects — absolutely. In Agile environments, we often hear: “We don’t do BRDs. We use user stories and product backlogs.” And that’s valid for fast-paced product teams, that works. But here’s the reality: * Not every project is a product. * Not every stakeholder thinks in sprints. * Not every team runs pure Agile. When working on cross-functional projects, enterprise implementations, or compliance heavy initiatives, I still find Business Requirements Documents (BRDs) incredibly useful — not as red tape, but as alignment tools. Here’s how I typically structure one: 1. Executive Summary – The “why now?” snapshot 2. Business Objectives – Outcomes that matter 3. Scope – What’s included, what’s excluded 4. Stakeholders & Roles – Who’s doing what 5. Functional & Non-Functional Requirements – What the system should do and how well it should perform 6. Assumptions, Constraints, Dependencies – Because projects don’t happen in isolation 7. Proposed System Overview – High-level solution view 8. KPIs & Success Criteria – So we know we’re not just delivering, but delivering value And let’s be clear: BRDs aren’t one-size-fits-all. They vary by company, methodology and even the maturity of the team. Sometimes it’s a full document. Sometimes, it’s a lean version that feeds directly into a product backlog. ✨ The goal isn’t formality. The goal is clarity. Whether you call it a BRD, a vision doc or something else what matters is shared understanding. #BusinessAnalysis #BRD #AgileProjects #ProjectManagement #BAcommunity #RequirementsEngineering #StakeholderAlignment #DeliverySuccess

How I Elicit requirements as a Business Analyst (for a brand new project in the planning phase) When a new project kicks off, I’m not diving straight into the details. Instead I start by setting the right foundation. Get clarity and structure first, and then move into documentation. Here’s my approach → Understand the business context. What are we trying to solve? Why now? If you skip this, you’ll end up capturing requirements with no real direction. → Map out key stakeholders. And don’t just talk to the usual suspects… bring in Legal, Compliance, Security, etc., early. Cross-functional input now = less rework later. → Break the project into logical categories. Before jumping into process maps or detail, I define the bones - the high-level steps or categories of the process or journey that your project is implementing. This structure helps guide future workshops and gives everyone a clear mental model of the scope. → Capture high-level requirements. Meet with stakeholders and start gathering their inputs. Use the categories above to guide discussions… and where it helps, co-design the high-level process to elicit requirements. I then use user stories at this stage; it keeps things outcome-focused, even when we’re still defining the “what.” → Document just enough. No 50-page BRDs here. I use Jira, Confluence and lightweight templates that the whole team can actually engage with. → Engage stakeholders to validate. Don’t assume your documentation speaks for itself. Walk stakeholders through what’s been captured… clarify assumptions, confirm priorities, and bring them along the journey. It’s the easiest way to spot gaps early and avoid those “wait… that’s not what I meant” moments later. → Baseline and prepare for the next phase. Once validated, baseline the high-level requirements and identify any dependencies or open items. This creates a clear handover point; setting you up for detailed requirements, solution design, or sprint planning in the next phase. → The goal at this stage? Clarity, alignment, and momentum - not perfection. If you follow these steps, I promise: → Your stakeholders are going to be happy → Requirements higher quality → Reduce risks of missed requirements → Much higher chance of project success If this resonated with you → that’s exactly what we teach in our BA Mentoring sessions in BA Bootcamp. We focus on practical skills that make your work clearer, your stakeholders happier, and your value stand out.

I wish I knew these 5 Requirements Engineering basics when I started my career 10 years ago, I was a fresh-faced engineer struggling with the basics of Requirements Engineering. If only I knew then what I know now... Here are 5 Requirements Engineering basics I wish someone had told me when I started my career: 1. Requirements are about WHAT, not HOW I used to dive straight into solutions, eager to show off my technical skills. Big mistake. The best Requirements Engineers focus on capturing WHAT the system needs to do, not HOW it should do it. Leave the implementation details to the developers. 2. Stakeholders are your best friends (and worst enemies) I once spent weeks perfecting a requirements document, only to have it torn apart in the first stakeholder review. Lesson learned: Engage stakeholders early and often. Their input is invaluable, but their expectations can derail your project if not managed properly. 3. Ambiguity is the enemy of good requirements "The system should be fast." What does that even mean? 🤔 I learned the hard way that vague requirements lead to misunderstandings, scope creep, and unhappy clients. Now, I always aim for SMART requirements: Specific, Measurable, Achievable, Relevant, and Time-bound. 4. Requirements traceability isn't optional I used to think traceability matrices were a waste of time. Until I had to explain why we built a feature that wasn't in the original requirements. Traceability isn't just bureaucracy – it's your lifeline when scope changes, priorities shift, or stakeholders question your decisions. 5. User stories ≠ requirements When Agile methodologies gained popularity, I thought user stories would replace traditional requirements. I was wrong. User stories are a great tool for capturing user needs, but they're not a substitute for detailed, testable requirements. The best approach? Use both. Let user stories drive the conversation, then flesh them out with specific requirements. → Here's the kicker: According to a study by IAG Consulting, companies with poor requirements practices waste an average of 41.5% of their project development resources. That's nearly half of your budget down the drain because of poor requirements! Mastering these basics isn't just about being a better engineer – it's about delivering real value to your organization.

A senior engineer joined a team I was advising. First week, he spotted a weird workaround in the payment flow. He cleaned it up. Payments broke on a Friday at 4:55 PM. $47K in failed transactions before anyone caught it. The workaround existed because the payment provider times out on large carts. The retry logic caused double charges. The workaround prevented duplicates. Nobody had written that down anywhere. The team learned the same lesson twice. Once in production. Once in the postmortem. Here's the documentation problem most teams don't see: Skip it → institutional knowledge disappears the moment someone leaves. Document everything → shipping slows to a crawl. Docs drift. Reality moves faster than Confluence. The fix is a 3-part minimum documentation standard: The decision — What did we choose? What did we rule out? "We kept the workaround in the payment flow." The reason — Why does this exist? What constraint forced it? "Provider times out on large carts. Retry logic caused duplicate charges." The consequences — What breaks if someone removes this? When to revisit? "If removed, duplicates return. Revisit when provider supports idempotency keys." Three parts. One page. One link in the PR. What to document every time: ✓ Architecture decisions that change the shape of the system ✓ Weird workarounds that look wrong but are right ✓ External constraints — vendors, compliance, rate limits ✓ Public contracts — APIs, events, schemas What to stop documenting: ✗ UI screenshots of interfaces that change weekly ✗ "How to set up the repo" essays nobody updates ✗ Meeting notes with no decisions ✗ Anything that duplicates what the code already says Ship the software. Document the why. Skip the rest.

After two decades heading Professional Services in SaaS, I've noticed something: requirements gathering is where most projects fall apart before they begin. The pattern repeats constantly. We send documentation. We schedule discovery calls. We ask about workflows and business rules. Then we wait. The truth? Customer contacts are swamped with daily operations. Even with a dedicated project manager, getting clear requirements is an uphill battle. Why Traditional Requirements Gathering Fails → The "Lift and Shift" Approach - Replicating old configurations sounds straightforward. Reality check: if your new platform mirrors the old one exactly, why switch? You'd still need detailed access to every workflow, automation rule, and custom field. → The Observation Method - Watching teams in action works on paper. Scheduling it? Nearly impossible. → The Top-Down Strategy - High-level leadership goals sound great until you need granular implementation details. The Real Problem The core issue isn't tools or templates. It's asking busy people to document processes they've never explained before.Like asking someone to write their exact coffee-making routine. They do it daily, but explaining every step? Completely different task. 3 Strategies That Actually Work → Start with Pain Points, Not Wish Lists Focus on current frustrations, not future wants. People describe pain easier than ideal workflows. Ask questions like: -"What happened when your system crashed during month-end close?" -"What manual task do you hate doing weekly?" → Explore Worst-Case Scenarios Edge cases reveal real requirements. Try: -"What happened when your CEO needed urgent approval but three approvers were out?" -"What happens when customers see conflicting information?" → Focus on Existing Metrics Current metrics reveal what matters. Ask about outcomes they already measure, not imagined features. →The Bottom Line The best requirements sessions feel like conversations where customers finally discuss what's not working. What's worked for you in gathering requirements effectively?

Requirement Gathering is not a step. It’s an art. 🎯 Early in my career, I thought requirement gathering meant one thing: 👉 Schedule a meeting 👉 Ask questions 👉 Write everything in a document Simple, right? Not really. Over time, I realized that the real requirements are rarely spoken directly. They are hidden in workflows, frustrations, and sometimes even in what stakeholders don’t say. That’s when I started using a mix of techniques instead of relying on just conversations 👇 🔹 Stakeholder Interviews To understand expectations, goals, and business pain points in depth 🔹 Workshops / JAD Sessions To bring multiple stakeholders together and align different perspectives 🔹 Observation (Job Shadowing) Because what users do is often very different from what they say 🔹 Surveys / Questionnaires To gather inputs at scale, especially from distributed teams 🔹 Document Analysis To decode legacy systems, existing workflows, and hidden dependencies 🔹 Prototyping / Wireframing To convert abstract ideas into something visual and testable 🔹 Brainstorming Sessions To explore possibilities and uncover innovative solutions 🔹 Interface Analysis (API / System Thinking) To understand how systems interact and where data truly flows ⸻ 💡 The biggest lesson? There is no “one-size-fits-all” technique. Great Business Analysts don’t just gather requirements, they choose the right technique at the right time. Because: ✔️ Stakeholders may not articulate the real problem ✔️ Documentation may be outdated ✔️ Assumptions can lead to costly mistakes ⸻ 🚀 In today’s world (AI, fast delivery, complex systems) Requirement gathering is no longer about writing BRDs… It’s about: ✨ Asking better questions ✨ Connecting the dots ✨ Challenging assumptions ✨ And delivering clarity in chaos ⸻ The best BAs don’t just document requirements… They uncover what truly needs to be built. ⸻ Curious to know 👇 👉 Which technique do you rely on the most in your projects? #BusinessAnalyst #RequirementGathering #ProductManagement #Agile #AI #CareerGrowth #Analytics #BACommunite

“That’s not what the requirement says!” Have you ever been in this type of argument? Product requirements (and other design requirements) are crucial for medical device development but are difficult to write and often difficult to understand. And misunderstandings can lead to expensive mistakes and delays. Which is ironic since requirements are supposed to enhance communication in a product team and with all the stakeholders.   Here are some recommendations, learned over years of painful experience, to improve your product requirements and minimize confusion. 1 - Make it a team effort: make one person responsible for the completion of the requirements document but make sure many people from different functional groups are involved in reviewing and commenting on the drafts. This helps in identifying missing requirements and correcting confusing wording. 2 - Use standardized terminology and syntax: requirements are not literature—save the creativity and innovation for designing the product, not for the wording of the requirements. Establish a product glossary and use those terms religiously in the requirements (don’t invent three different names for the “Axial Controller Module”). Adopt a standardized syntax such as EARS (https://lnkd.in/dTHWSwjb), which forces requirements to be written with a standard structure. This reduces the chances of misinterpretation of the requirements. 3 - Define the testing with the requirements: make sure every requirement is testable or otherwise verifiable by writing down alongside it how you plan to test it or otherwise verify it. This simple exercise highlights poorly written requirements and will also give the team a head start on V&V planning. 4 - Manage drafts carefully: during product development the latest rev of the requirements document in Doc Control is not what everyone wants to see—they want to find the latest draft of the next rev of requirements. In other words, it’s crucial that everyone can see all the changes being made to the requirements. If the latest draft is an Excel spreadsheet being emailed around, then there’s likely to be confusion. Make sure there’s one place where everyone can see the latest draft of the requirements. A good requirements management tool will automatically avoid this problem by providing a single source of truth at all times, regardless of how fast the requirements are changing.   What tips do you have to help improve requirements for medical devices?

If your requirements live outside the tools your teams use to design and validate, you’re managing blind. That’s when change sneaks in, spreadsheets drift, and decisions get made on stale context. I’ve watched capable teams burn weeks on late change notices and heroic integrations because the requirements weren’t connected to the work.     The cost of ignoring this is well documented. A landmark study by Texas Instruments found runaway costs 7 out of 10 times when teams failed to keep requirements current. Projects that relied on documents or databases alone still saw high runaway rates. Add that test and integration often consume 50 to 60 percent of the lifecycle, and you can see why linking each requirement to test cases and design items is non‑negotiable. Another lesson from that research. Nearly all of your cost is locked in by the time you hit development. Decisions made early, with live requirements, decide whether your program will be late or lean.     Here’s the practice that consistently stabilizes complex, multi‑site programs. Treat requirements as a living system. Map each requirement to a specific design item, a test case, and a program constraint. Make the system web‑accessible and usable from common desktop tools so every entitled person can read, edit, and trace without a learning curve. Use notifications to flag parts and schedules at risk when a requirement changes.     The payoff for energy and utilities teams is concrete. Faster change assessment because every requirement has a home. Shorter test cycles because reruns automatically verify compliance. Better supplier conversations because requirements arrive early enough to adjust parts or propose alternatives. Most important, quality is designed in upstream, not inspected downstream.
