Run one case in a short multiplayer room, or launch a prepared FRAME programme for a new cohort.

Choose by the time you have.

Both formats use the same FRAME language. The difference is whether the team needs one useful conversation or a full learning journey.

30–90 minutes

Solve one case together.

Use a live room for an offsite, class, leadership meeting or one-hour workshop. Everyone commits before the room can influence them.

Create a case room

Host sign-in required · the invitation itself is public

  1. 01

    Choose one case

    The host gives everyone the same evidence and decision.

  2. 02

    Share one public link

    People can open the invitation before they sign in.

  3. 03

    Everyone answers first

    No one sees another memo or the choice split before submitting.

  4. 04

    Reveal when ready

    The host stops answers and opens the room for discussion.

3–8 weeks

Run a programme for a new cohort.

Give L&D a prepared path made from the current Business Judgement Course and real-company cases. No new content build is required.

Public preview · no sign-in

  1. 01

    Choose 3, 6 or 8 weeks

    Use a prepared sequence from the existing course and case library.

  2. 02

    Add the cohort

    Paste emails, choose a start date and send the public invitation.

  3. 03

    Run the weekly rhythm

    Course chapter, private decision, FRAME feedback and a fresh case.

  4. 04

    Close with cohort evidence

    Compare baseline and final patterns without exposing individual work.

One FRAME language inside both formats.

A short room and a cohort programme should feel like the same product. FRAME gives every case, review and debrief the same five questions.

F

Frame

Name the decision and its limits.

R

Relevant evidence

Use facts that could change the call.

A

Alternatives

Compare a serious second path.

M

Manage uncertainty

Name the risk, trigger and fallback.

E

Execute and learn

Commit and say when to revisit.

Private for the person. Useful for the cohort.

Individual memoranda and scores stay private. The organiser gets enough information to run the experience and, in programmes, a group-level report.

Each participant keeps

  • Written memoranda
  • Individual FRAME scores
  • Evidence behind feedback
  • Personal next practice

The organiser sees

  • Invited, joined and submitted
  • Reminder controls
  • Choice split after reveal
  • Cohort movement from five pairs

No individual ranking. No use for hiring, promotion, dismissal or compensation.

Fit the format to the team you already serve.

Open a one-case room for a short session, or use a prepared programme where the audience needs repeated practice and cohort evidence.

Questions about multiplayer.

01What is the difference between a room and a programme?+

A room is one case for one short team session. A programme runs for 3–8 weeks and combines the existing Business Judgement Course with a prepared sequence of real-company cases, invitations, reminders and a closing cohort report.

02Can the host decide when a room starts and ends?+

Yes. A room can start with the host alone and accepts up to 50 players. The host decides when to close joining, start answers and reveal the results. Team licensing is based on named seats.

03What can the organiser see?+

The organiser sees participation states and reminder controls. Individual memoranda and individual FRAME scores remain private. Programme aggregates appear only after at least five people complete both baseline and final decisions.

04Are individual accounts free?+

Yes. Register by 15 September 2026 and both personal access and team access stay free forever for that account. No card is required.

05Is this an employee assessment?+

No. decidenda is for development and deliberate practice. Learning signals must not be used for hiring, promotion, dismissal or compensation decisions.
