Stakeholder Walkthroughs That Reveal Hidden Issues
One small but powerful decision separates modelers who build trusted, executable processes from those who deliver diagrams that mislead. It’s not about tools or complexity — it’s about who you involve in the review. Too many models are validated only by peers or technical architects, leaving business logic, assumptions, and handoffs unchallenged. I’ve seen teams ship processes that ran perfectly in simulation but failed in production — not because of modeling errors, but because a critical path was never discussed with the actual users.
BPMN stakeholder walkthroughs are the bridge between theory and execution. They’re not meetings to present diagrams — they’re collaborative sessions to test understanding, surface gaps, and validate assumptions in real time. When done right, they uncover contradictions, clarify responsibilities, and reveal missing exceptions long before automation begins.
Consider this: a modeler once showed a mortgage approval process with a single “Review Application” task. The business user paused, then said, “We don’t review the application — we check credit, verify income, and validate documents.” That moment exposed a fundamental disconnect: the model used the wrong task type, ignored parallel checks, and assumed a single approval gate. A simple walkthrough changed everything.
Why Walkthroughs Work Better Than Static Reviews
Static reviews catch syntax errors, but only walkthroughs expose semantic flaws. A diagram may be technically correct — all flows are connected, gateways are paired, events are properly placed — yet still represent a process that doesn’t reflect reality.
Think of a walkthrough as a “dry run” with people, not software. You simulate the process step by step, using real-world scenarios. You ask: “What happens next?” “Who does this?” “Is this how it actually works?”
These are not rhetorical questions. They’re invitations to reflect, correct, and confirm.
Preparation: Set the Stage for Success
Walkthroughs fail when unstructured or rushed. Preparation is key. Before starting, ensure:
- The diagram is complete and has passed a preliminary peer review.
- Key stakeholders — process owners, frontline workers, and subject matter experts — are invited.
- You’ve selected 2–3 representative scenarios: one normal flow, one exception, and one edge case (e.g., late payment, incomplete documents).
- A facilitator is assigned — someone neutral who guides the session, not the modeler.
Share the diagram in advance. Don’t assume everyone has the same level of familiarity.
How to Conduct a BPMN Stakeholder Walkthrough
This isn’t a presentation. It’s a conversation. Use a structured approach:
1. Start with the Big Picture
Begin by showing the overall scope: what the process does, who’s involved, and what triggers it. Use plain language. Avoid jargon.
Ask: “What do you expect this process to accomplish?”
Listen for mismatched expectations. If the modeler says “We process loan applications,” but the user says “We close loans,” you’ve already found a scope issue.
2. Walk Through Scenarios Step by Step
Use the scenarios you prepared. For each, follow the flow from start to end.
At each step, pause and ask:
- “What happens here?”
- “Who owns this activity?”
- “Is this how you do it?”
- “What if this condition isn’t met?”
These questions force the user to engage, not just nod along.
3. Challenge Hidden Assumptions
Assumptions are the silent killers of BPMN quality. They live in things like:
- “The system sends an email” — but who sends it? Is it automated or manual?
- “The customer confirms” — but what if they don’t? Is there a timeout?
- “We review the form” — but is this one review or multiple checks?
Ask: “What happens if the customer doesn’t respond in 48 hours?” or “If the data is invalid, who fixes it?”
These questions expose missing exception paths, unhandled decisions, and unclear ownership.
4. Capture Feedback Clearly
Use a whiteboard, shared document, or sticky notes to track feedback. Don’t let discussions drift.
Write down each issue as:
- Issue: “No timeout is defined for customer confirmation.”
- Impact: “Could lead to indefinite delays.”
- Suggested Fix: “Add a 48-hour timeout with escalation to supervisor.”
Label each item: “Fix in next version.” “Needs clarification.” “Document for reference.”
Proven Questions to Uncover Flaws
Not every question needs to be deep. Some simple ones reveal the most.
- “Can you walk me through how this step actually happens?”
- “Who is responsible for this task — and how do they know it’s their turn?”
- “What would make this task fail? Where does it go then?”
- “Is this process the same for all customers, or does it change based on loan type?”
- “What happens if two people do the same task at once?”
These aren’t tricks. They’re invitations to reflect. If a user hesitates or says “Well, it depends,” you’ve found an ambiguity — and a model gap.
Common Patterns of Hidden Issues
| Issue Type | Typical Sign | How to Test |
|---|---|---|
| Unrealistic timelines | “We do this in 1 day” — but the user says “We can’t start until Monday.” | Ask: “When can this actually start?” |
| Missing exception paths | “No email sent” — but the user says “We call the customer if it’s not resolved.” | Ask: “What if the email fails?” |
| Overlapping responsibilities | “The customer provides data, and the clerk verifies it” — but both roles are in the same lane. | Ask: “Who signs off? What if the data is wrong?” |
| Incorrect task ownership | “The system sends a notification” — but user says “I have to do that manually.” | Ask: “When does this happen? Is it automated?” |
Best Practices for Effective Walkthroughs
Even the best questions fail without the right setting.
- Keep it small: 3–5 stakeholders max. More leads to noise.
- Time-box: 45–60 minutes. Long sessions lose focus.
- Assign a note-taker: Someone not involved in the model can capture feedback objectively.
- Use real tools: Show the diagram in the modeling tool, not a static image.
- Document everything: Share a summary post-session — decisions made, changes requested, open questions.
When to Avoid Walkthroughs
Not every diagram needs a walkthrough. Consider skipping if:
- The process is well-understood and stable.
- The model is for internal documentation only (e.g., system flow).
- The audience has already validated the model in a prior session.
But if the process involves new users, new roles, or complex handoffs — run a walkthrough.
Frequently Asked Questions
How do I get business users to participate in walkthroughs?
Invite them directly. Frame it as “Help us get it right” — not “We’re showing you a diagram.” Emphasize their input is essential. Offer a clear agenda and respect their time. If they’re skeptical, start small: pick one task, walk through it together, and show the value of their feedback.
What if stakeholders disagree during a walkthrough?
That’s normal. Document the conflict. Note: “User A says X, User B says Y.” Flag it for follow-up with the process owner. Don’t force consensus — clarify who has final authority. The goal is visibility, not agreement.
Can I use walkthroughs for complex or large processes?
Yes — but break them down. Focus on high-risk lanes, exception paths, or handoffs. Use a “high-level walkthrough” first, then drill into sub-processes. Avoid trying to walk through every detail in one session.
Is a walkthrough the same as a peer review?
No. Peer reviews focus on notation, syntax, and consistency. Walkthroughs focus on meaning, logic, and reality. Use both. A peer review catches errors. A walkthrough uncovers flaws.
What if the stakeholder says “This is how we do it” but it’s not efficient?
That’s the point. Your job isn’t to fix it — it’s to document how it is. Flag it. Note: “Process reflects current practice, but may not be optimal.” Then, recommend a separate optimization session.
How often should I run walkthroughs?
For new models, always. For updates, run one if the change affects logic, roles, or handoffs. For stable processes, every 6–12 months — or when a major business change occurs.
