Process discovery interview to process map

Business analysts and consultants learn most processes in stakeholder interviews. Wavelength turns the interview into a process map while the stakeholder talks. The stakeholder sees the map on screen and confirms it before the interview ends.

Wavelength is a voice to diagram tool. This page shows how to use it in process discovery interviews.

Why map during the interview

When you draw the map after the interview, you find gaps. The stakeholder is not there to answer them. You must book a second meeting. When you map during the interview, the stakeholder sees each gap and fills it in the same meeting.

A map on screen also gives the stakeholder something to correct. A stakeholder who reads "Finance approves" can say "no, the controller approves." A stakeholder who reads your notes later rarely does this.

How it works

Hold the mic. The map builds while you hold the mic. If the stakeholder sits near your microphone, hold it while they talk. If not, repeat each step aloud in your own words.
Share your screen. The stakeholder sees each actor, system, and decision when it appears.
Ask about the dashed amber lines. Each one is a link that the AI inferred. Ask the stakeholder to confirm it or correct it.
Fix the map in the meeting. Drag a node, rename it, or say the change in plain English.
Upload when live mapping is not possible. After the interview, upload the recording or the transcript. Wavelength builds the map from the file.

Interview questions that give a good map

What starts this process?
Who does the first step, and in which system?
What happens next, and who does it?
Where does someone make a decision? What is the rule?
What happens on each branch of that decision?
Where is the data kept between steps?
What happens when something goes wrong?
How do you know the process is finished?

Ask one question at a time. Let the stakeholder answer in full before the next question. Each answer adds nodes to the map.

A worked example: one interview segment

Analyst: What starts the process? Stakeholder: A customer emails a change request to the support inbox. Analyst: Who picks it up? Stakeholder: A support agent logs it in Jira. If it is a billing change, it goes to the billing team. If not, the product owner reviews it. Analyst: Where does the approved change go? Stakeholder: Engineering builds it, and the release notes go on a Confluence page.

The map from this segment has these parts:

Actors: Customer, Support Agent, Billing Team, Product Owner, Engineering.
System: Jira.
Data stores: Support Inbox, Confluence Release Notes.
Decision: Billing change? with a "yes" branch and a "no" branch.

The stakeholder did not say what the billing team does next. The map stops at the billing team. That gap is your next interview question.

Merge several interviews

One stakeholder rarely knows the full process. Sales knows the start. Finance knows the end. IT knows the systems. Map each interview as its own flow first.

Then compare the flows. Take the confirmed steps from each flow and talk through one combined walkthrough. Map it as a new flow. When two stakeholders describe the same step in different ways, record both versions and take the question back to them. Three interviews and one combined map fit in the 5 saved flows of the Free plan.

By hand or with Wavelength

Task	By hand	With Wavelength
Capture the interview	You type notes and listen at the same time.	The map builds while you hold the mic.
Confirm the process	You send a drawing days later and wait for comments.	The stakeholder confirms the map on screen in the meeting.
Find gaps	You find them after the meeting.	Dashed amber lines and dead ends show them during the meeting.
Combine interviews	You redraw one large map from many notes.	You map each interview, then map one combined walkthrough.
Deliver the result	You redraw the map for the client deck.	Export PowerPoint, PDF, BPMN, or draw.io.

After discovery

Export the confirmed map for the readout. Use BPMN or draw.io when the client team continues to model the process. Use the free SOP generator to write the procedure for each process. For calls that are already recorded, follow the transcript to flowchart method. For a quick map from a written description, use the AI diagram generator from text.

Common questions

Can Wavelength map an interview live?

Yes. Hold the mic and the map builds while you hold it. Share your screen so the stakeholder can confirm each step.

What if I cannot map during the interview?

Upload the recording or the transcript after the interview. Wavelength takes .mp3, .m4a, .wav, .mp4, .mov, .txt, .md, .vtt, .srt, .json, .pdf, and .docx files.

How do I combine several interviews?

Map each interview as its own flow. Then map one combined walkthrough from the confirmed steps in each flow.

Does the stakeholder need an account?

No. The stakeholder watches your shared screen. Only the person who builds the map needs an account.

What can I give the client after discovery?

Export the map as PNG, PDF, PowerPoint, draw.io, Mermaid, BPMN, n8n, or Make.
