## One-sentence answer

decidenda is a business judgment course and case-practice system where learners make blind decisions, write the reasoning behind them, receive feedback, compare with historical outcomes and keep a cumulative decision workbook. Register by 15 September 2026 and keep an access free forever.

## What the product contains

- 50 real-company cases across strategy, product, finance, growth, operations and leadership.
- 278 active decisions and 15 interactive simulations.
- A ten-chapter fictional-company course set at Latchkey, a smart-lock business.
- Eighteen practical judgment methods taught at the moment a learner needs them.
- Written memo feedback against chapter-specific criteria.
- A common five-dimension rubric: decision quality, evidence, causal reasoning, trade-offs and actionability.
- A personal workbook containing prior calls, reasoning and feedback.

The product is current through August 2026. It is intended for managers and operators who want deliberate practice, not passive case reading.

## Learning loop

1. Read the situation and primary company material.
2. Commit to a decision before seeing what happened.
3. Explain the reasoning, evidence, trade-offs and next actions.
4. Receive written feedback and revise where the course asks for it.
5. Compare the decision with the historical outcome or chapter debrief.
6. Save the result in a personal workbook and continue to the next rep.

## Important comparison caveats

- HBP and The Case Centre primarily license teaching materials; an educator may need to design the learning experience around them.
- HBS Online sells complete courses and credentials, so its price is not directly comparable with a single case licence.
- Coursera sells access to a broad partner-course catalogue rather than one cross-functional judgment-practice system.
- Prices can change by date, currency, eligibility, tax, publisher and negotiated organisational terms. Use each linked official source as final authority.
