Tools & workshops

A room full of opinions goes in. One plan comes out.

DEFINE is two weeks of focused workshops. These are the four I run most, the tools we put on the wall, and the question each one settles.

  1. 01 Persona interviewsWho are we building for?
  2. 02 Value Impact MapWhat is each piece worth?
  3. 03 Story mappingWhat could we build, and what first?
  4. 04 RoadmapIn what order, and why?
Day 1, 9:00
A ROOM FULL OF OPINIONS
01 Persona interviews · Days 1–3

Listen before anyone draws a box.

What you getYou build for the people who actually do the work, not just the people in the meeting, so you stop paying for features nobody asked for.

I interview the people who use the work and the people who do it, not only the people who manage it. That’s where the hidden workarounds are. Then, in a persona workshop, we turn what we heard into a few people everyone in the room can picture.

Ask for stories, not opinions

“What would you want from a new system?”

John · line operator

“Hmm… a dashboard, maybe? Something faster. And it should work like the old one.”

Polite, vague, and no use for design.

You leave with personas built from evidence: who they are, the tools they use today, their pain points, and what they do not want.

02 Value Impact Map · Days 3–5

Put a number on every box.

What you getEvery decision gets a number. Priorities are settled by value, not by whoever argues loudest, and you can show leadership exactly what each feature is worth.

Once we know who the users are, we start the Value Impact Map, before anyone talks about features. It reads left to right: the business objective, the impacts it needs on people’s behaviour, the features that cause them, and the success metrics that prove it worked. It becomes the project’s North Star.

Every level carries a number, and every number gets a baseline before we build anything. Without a “before”, nobody can prove the “after”. When two features compete for the same slot, the one that moves the North Star further wins, not the one argued for loudest.

03 Story mapping · Days 4–7

Map everything. Then draw the line.

What you getA first version that delivers the most value within your budget, plus a written list of what waits and why, so the scope stops creeping.

With the North Star in place, we go wide. Every story anyone can think of goes on a sticky note, written from a persona’s point of view, and lined up along the journey from left to right. Then we draw one line across the whole wall.

Everything above the line is the MVP: the thinnest slice that still works from start to finish. Everything below it waits, with a reason. That “Not now” list is what protects the first version from creeping.

04 Roadmap · Days 8–10

A plan your team can start on the next morning.

What you getA plan your leadership and your engineers read the same way, which your team can start on the next morning.

We place the features on a timeline that respects what depends on what. Process flows and mockups for each feature are where those dependencies come to light, before anyone writes code.

Each item keeps its number from the Value Impact Map, so the team always sees why it’s building it. For leadership, the same plan reads as Now, Next and Later: clear direction, without promising dates for work that’s still uncertain.
