Illustrative project · Independent coffee subscription
Start with customers, value and revenue to shape a coffee subscription model.
Why would a customer choose you?
One customer group, a useful offer, a revenue assumption. Start with concrete questions and choose a model that helps you answer them.
Explore all modelsOne conversation. Five specialist perspectives.
Work with your general assistant and draw on five specialist perspectives. Your model and project material give the discussion context.
A question from the coffee project
Which customer group should we serve first?
Compare home drinkers and small offices. Examine what each choice changes in your offer, distribution and costs.
These are example questions. You review the suggestions and decide what belongs in the project.
A working decision
Test home coffee drinkers first
Find out whether they need regular delivery. If the reason to reorder is weak, revisit the customer group.
Prepare interviews
Keep the evidence and the open questions alongside the decision.
A decision. Then the work.
Record why you chose a direction and set the next task. Return to that decision when new evidence arrives.
What are you working on?
A new business, a team project, or an important review. Start with the work in front of you.
For project leads
Move a team project forward
Bring project material, decisions and tasks together so everyone can see what is happening and why.
For investors and reviewers
Structure a project review
Review customers, value, delivery and revenue. Separate the evidence you have from the questions still open.
