A focused week for the behavior behind your retention problem.
The Retention Sprint helps a digital-health team agree on what people need to do, why they are getting stuck, and which product experiment is worth running next.
What you leave with
The output is meant to survive the meeting. Your team should know what was decided and be able to act on it without me in the room.
Target behavior statement
A precise description of who needs to do what, when, and in which context. This becomes the shared problem definition.
Behavior diagnosis
A COM-B map of the capability, opportunity, and motivation barriers supported by the evidence you already have.
Ranked intervention directions
A short list of product moves connected to the diagnosed barriers, with the tradeoffs written down.
Experiment plan
One selected idea with a hypothesis, prototype scope, success measure, and the next decision your team will make.
Decision document
A concise record your team can share after the sprint instead of trying to reconstruct the workshop from sticky notes.
How the five days work
Before day 1
You send the current flow, research, analytics, support themes, and the decisions your team is stuck on.
Day 1
I review the evidence and write the first target-behavior draft.
Day 2
We run a 90-minute working session with the people who own the product decision.
Days 3–4
I complete the diagnosis, build the intervention shortlist, and shape the recommended experiment.
Day 5
We review the decision document together. I make one round of focused revisions afterward.
A good fit
- Your product depends on a patient, member, caregiver, or clinician doing something more than once.
- The team can point to one moment where behavior breaks down.
- You have some research, analytics, support evidence, or subject-matter knowledge to work from.
- Someone on the call can decide what gets prototyped or tested next.
Probably not a fit
- You need a full redesign, a large research study, or production interface work inside one week.
- The challenge is still “improve the whole product” and nobody can narrow it yet.
- You want a workshop that produces lots of ideas but no owner for the next decision.
- You need a promise that one intervention will create a clinical outcome. Behavioral science cannot honestly make that promise.
I’m Jameson Daines.
My background spans product design, pharmaceutical human factors at AstraZeneca, health-tech work on Samsung Galaxy Watch, and an MSc in Behaviour Change from UCL. I built the BehaviorUX Canvas because product teams needed a practical way to use the research while making decisions.
Questions I’d ask too
What kind of problem fits?
A narrow behavior with a visible product moment works best: finishing onboarding, returning after week one, following a treatment task, responding to a reminder, or completing a health action. “Fix retention” is too broad until we choose the behavior underneath it.
How many people join?
Usually three to six people. I want the product owner and the person closest to the research or data in the room. Design, clinical, behavior science, or engineering can join when they own part of the decision.
Do you design the final screens?
The sprint ends with an experiment direction and enough detail for your team to prototype it. Final interface production is outside this fixed scope, but I can quote that separately if it is useful.
What if the evidence is thin?
I will separate what the evidence supports from what we are assuming. If the missing information blocks a useful diagnosis, I will recommend the smallest research step instead of pretending the answer is already there.
Why is the first price lower?
BehaviorUX has strong methods and relevant experience, but this exact packaged sprint is new. The first three teams get the lower price in exchange for helping me tighten the format. I will only publish a case study or quote with written permission.
Tell me where the behavior breaks down.
You don’t need a polished brief. Bring the product moment, the evidence you have, and the decision that keeps circling.
