How I work with AI

From brief to prototype.

I use ChatGPT to structure observations and compare options. With Codex, I make the chosen option testable. I prepare the context, decide with the team and check the result.

Try the prototype

Research · ChatGPT

I tie each finding to a source.

I prepare anonymised notes and the constraints of the application. ChatGPT proposes a grouping. I go back to the notes to check the links and decide what to tackle.

I prioritise resuming the application. A document already received needs to stay visible.

See the prompt

Using notes N1 to N3, identify the difficulties, cite the relevant notes and distinguish observations from assumptions.

Example research notes
  1. N1Someone uploaded a document again after it had already been received.
  2. N2The missing document went unnoticed.
  3. N3On returning to the application, the person was unsure what to do next.

Decide · ChatGPT

I choose what people see first.

I ask ChatGPT for two ways to organise the same application. With the product owner, I clarify the priority. With engineering, I check which states the system can retain after a file is rejected.

In this example, I put the missing document first and keep the received documents visible below.

See the prompt

Propose two screens with the same data. Compare a list of all documents with a screen that opens with the next action.

All documents

  • CertificateReceived
  • Proof of addressRequired
The customer has to find the missing document in the list.
Selected direction

Next action

  • Proof of addressRequired
  • CertificateReceived
Try adding the document
The customer sees what to send as soon as they open the application.

Prototype · Codex

I test what happens when an upload fails.

I ask Codex to build the flow and its states. Here, I set up an oversized file and an accepted PDF. Try both and see what happens to the certificate.

See the prompt

Build a prototype with sample files. If the new document is rejected, keep the certificate marked as received. Make it possible to retry with a keyboard.

Interactive prototype

Your application

  • CertificateReceived
  • Proof of addressRequired

I share what the team needs to decide and build.

  • For the product owner

    The decision and what to track after release. Here, the number of documents uploaded again after they were already received.

  • For engineering

    Application states, error copy, the 8 MB limit and how a customer resumes the flow.

  • For acceptance testing

    Two scenarios to run in the prototype. A rejected upload keeps the first document. A valid PDF completes the application.

I share only the context the task needs and work in the environment approved by the client.
