Business tool with Codex
How to prototype a business tool with Codex?
- Codex
1250 € per session, excl. VAT
In short
For professionals seeking a specific application, this training allows participants to describe user journeys and request a first local interface. Participants build with Codex a local calculator or form prototype, complete with tests and documented limitations. This helps verify calculations and entries, resulting in a tool ready to evolve for your specific business needs.
Why this training?
- The problem
- Fragmented uses and results that are hard to verify.
- What it costs today
- Manual rework and decisions based on incomplete information.
- Why this skill
- A demonstration business prototype with tests, review and documented limitations.
- What you gain
- A demonstration business prototype with tests, review and documented limitations.
Objectives of this training
- Describe users and their flow.
- Request an initial local interface.
- Check calculations, inputs and failures.
- A demonstration business prototype with tests, review and documented limitations.
Who is it for and what are the prerequisites?
Roles and tasks concerned
- Professionals seeking hands-on practice with a specific use case
Prior skills
- AI Fundamentals and AI Prompting completed, or equivalent experience (a learning prerequisite, not a registration condition).
- Have practised: How to have a change reviewed and tested by Codex before validating it?, or have equivalent skills. Compatible Codex account and authorised demonstration environment; verify repository, terminal, tests and connectors with least privilege. No secrets or live deployment; human review is required, with no automatic production validation.
- A paid subscription to an AI solution offering the features used, the organisation’s authorisation for third-party tools, and the actual accounts and access rights.
To prepare before the session
- Compatible Codex account and authorised demonstration environment; verify repository, terminal, tests and connectors with least privilege. No secrets or live deployment; human review is required, with no automatic production validation.
What you will work on
Specify
Describe users and their flow.
Build
Request an initial local interface.
Test
Check calculations, inputs and failures.
Prepare next steps
Fix observed defects.
Adapt the prototype to a second test set
Change one business rule in the demonstration prototype, request a bounded Codex plan and compare the diff against original criteria.
Prepare the business prototype review
Have a colleague reproduce a scenario and its tests; inspect the diff, dependencies and uncovered risks together.
What you take away
- A local calculator or form prototype with tests and documented limits.
Method and assessment
- Demonstration of available features, guided exercises and an independent case.
- Peer review of the deliverable and correction against original sources.
The participant presents the stated deliverable, justifies sources and permissions, identifies and corrects an error and explains limitations. Assessment rubric: accuracy, traceability, access control and handover to a colleague.
