Field Notes / The semester notebook

Go out curious.
Come back with
better questions.

A starting chapter, with seven semesters still ahead. This notebook is where I want to connect the people I learn from, the places I explore, and the ideas I test as I learn the whole journey from product to business.

A starting point. Seven semesters ahead.
Room for multiple projects and learnings in each chapter.

Semester 01.

Projects, experiments, conversations, and lessons from this semester stay together here. Each entry has its own image, question, analysis, evidence, and next step.

0 published entries · 3 example formats

Example format · Founder conversation

The decision behind the first customer.

This is an example format, not a completed project or a claim of a real meeting.

Example format: follow a founder’s reasoning, the constraints around a decision, and the answer that deserves a second look.

The question

What changed between the original idea and something a customer chose?

The learning in brief

  • What was the founder trying to understand or solve?
  • Which decision changed after contact with a customer?
  • What did the conversation clarify, and what would need further evidence?

Evidence and supporting work

A dated conversation note, a public source, and any quote or photograph approved for sharing.

Understand the problem

Identify the customer, the task they were trying to complete, and the workaround they used. Separate the founder’s interpretation from what customers actually said or did.

Break it into decisions

Trace the original assumption, the evidence that challenged it, and the sequence of decisions that followed. Ask which constraint mattered most: time, trust, cost, capability, or access.

Test the solution

Record what was offered first, what was deliberately left out, and how the founder checked whether it solved the customer’s real problem.

Examine the business

Ask who used it, who paid, how the first customer found it, what it cost to deliver, and what would make someone return.

Reflect and continue

Write down what the conversation changed, what remains uncertain, and the next person, observation, or small test that could resolve it.

Example format · Company visit

The work behind the experience.

This is an example format, not a completed project or a claim of a real meeting.

Example format: connect an observation from a company visit to the people, systems, and trade-offs that make the business work.

The question

What has to happen behind the scenes for a customer promise to hold?

The learning in brief

  • Which process or part of the business was visible?
  • What did I directly observe, and what did someone explain?
  • Which detail changed my understanding of the customer experience?

Evidence and supporting work

A dated observation, a process sketch, or a public reference, with confidential details left out.

Understand the problem

Start with the promise made to a customer. Identify where the customer could experience delay, confusion, cost, or disappointment.

Map the work

Break the process into steps: request, decision, handoff, delivery, and follow-up. Note who is responsible and where information or work can get stuck.

Consider a solution

Choose one observed bottleneck. Compare a simpler process change with a tool or AI-assisted approach before assuming that new software is needed.

Examine the business

Connect the process to delivery cost, quality, capacity, and the reason a customer would choose this business again.

Reflect and continue

Distinguish what was directly observed from what was explained. Identify the evidence needed before recommending a change.

Example format · Applied learning

When the idea meets a test.

This is an example format, not a completed project or a claim of a real meeting.

Example format: record the starting assumption, the thing made or tested, the evidence, and the next decision.

The question

What did the attempt reveal that the original explanation could not?

The learning in brief

  • What question did this attempt set out to answer?
  • What did I make or contribute, and what happened?
  • Which assumption changed, and what would I try next?

Evidence and supporting work

A prototype or demonstration, a short evidence record, and a clear account of the work’s limits.

Understand the problem

Name a specific person and the outcome they need. Record the current workaround, how often the problem occurs, and the cost of leaving it unresolved.

Break it into a sequence

Map the task step by step. Separate symptoms from possible causes, list constraints and unknowns, and choose the assumption most likely to change the decision.

Build the smallest useful test

Compare possible approaches, including doing the task manually. Build only enough to test the riskiest assumption; use AI where its output can be checked.

Test business viability

Ask who would pay, why they would choose this solution, how they would find it, and whether price can cover acquisition, delivery, and support.

Learn and decide

Keep the result, including a disappointing one. Decide whether to improve, change direction, or stop, and explain the evidence behind that choice.
