English session plan

Original program status: draft. Source safety category: Medium; this is not a guarantee of safety.

Preparation: High preparation. Facilitation team: Four roles, including an experienced facilitator.

What this session can decide

Propose trial candidates, evidence needed and conditions for reversing course. Refer large investments and regulatory judgements for formal review.

Outside its scope

  • Do not assert future probabilities as established.
  • Do not approve irreversible investments.
  • Do not judge regulatory compliance.

Primary caution: Do not assert future probabilities as established.

Before starting

Question and scope
Examine strategic proposals under multiple external situations and clarify evidence gaps and withdrawal conditions. Before the session starts, state the subject and period to be covered in one sentence.
What is decided here
Propose trial candidates, evidence needed and conditions for reversing course. Refer large investments and regulatory judgements for formal review.
Output recipient
At the end, the Recorder retains “Comparison of options that can be tested and reversed”. Show decision-makers the trial scope, observation indicators and conditions for reversing course.
Participation and information boundaries
Explain that people may pass, rest or leave, and keep personal information, confidential information and judgements about attributes off the recording surface. Assign Participant support separately.
Operating team
Assign the Lead facilitator, Recorder, Timekeeper and Participant support before starting, and confirm who announces transitions and stops.
Next check
Decide the review date for “Comparison of options that can be tested and reversed”, who may view it and who is responsible for the next decision.

Who takes responsibility

Lead facilitator

Keep “Turn Uncertain Strategy into Reversible Choices” within its purpose and stated exclusions, and announce the start and end of each stage.

From before the start until the session ends.

Recorder

Record “Four scenarios”, “List of evidence gaps”, “Comparison of options that can be tested and reversed” at each stage and hand the records to their recipients at the end.

From preparation of recording surfaces before the start through storage after the session.

Timekeeper

Notify the Lead facilitator 3 minutes before each stage ends and when switching to breaks or buffer time.

At the start of every stage and 3 minutes before its end.

Participant support

Receive requests to pass, rest, leave or check individually, and decide with the Lead facilitator whether resumption is possible.

From before the start until the session ends.

Session flow

Minutes are measured from the session start. Method time, transition time, breaks and buffer are shown separately; they are not additional overlapping activities.

  1. 0–123 minutes

    Develop different external situations

    Method: Scenario Matrix · 0–120 minutes. Transition: 120–123 minutes (3 minutes).

    Select 2 uncertain axes with high impact and describe 4 situations. Add observable signs for each situation and distinguish desirability from prediction.

    Responsible: Lead facilitator; Recorder; Participant support

    Output: Four scenarios

    Handoff: Pass hypotheses that determine success or failure in each scenario to the stage that organises evidence gaps and checking methods.

    This stage may be shortened only in accordance with the stated conditions.

  2. 123–156 minutes

    Separate evidence gaps

    Method: Evidence Gap Board · 123–153 minutes. Transition: 153–156 minutes (3 minutes).

    Write strategic assumptions one at a time and classify them as known, assumed or unknown. For unknowns, record information sources, responsibility and a checking deadline.

    Responsible: Lead facilitator; Recorder; Participant support

    Output: List of evidence gaps

    Handoff: Pass important unknowns to the stage that sets trial scope and withdrawal conditions.

    This stage is not marked as shortenable.

  3. 166–194 minutes

    Set trial and withdrawal conditions

    Method: Reversible Choice Board · 166–191 minutes. Transition: 191–194 minutes (3 minutes).

    Separate options into reversible and difficult to reverse. For reversible options, set a minimum trial and withdrawal conditions; send difficult-to-reverse options for specialist review.

    Responsible: Lead facilitator; Recorder; Participant support

    Output: Comparison of options that can be tested and reversed

    Handoff: Pass the comparison of options that can be tested and reversed to strategic decision-makers and the people responsible for evidence collection.

    This stage is not marked as shortenable.

What is retained and who receives it

Four scenarios

Owner: Recorder

Provide a framework for comparing strategic proposals under different conditions.

List of evidence gaps

Owner: Recorder

Record what is known, assumed and unknown, and how to check it, for each strategic proposal.

Comparison of options that can be tested and reversed

Owner: Recorder

Show decision-makers the trial scope, observation indicators and conditions for reversing course.

Materials and setup

Material names, quantities, groups and handling instructions retain the fixed draft's original helper-derived guidance. Where a format is marked “Source material specification”, the entire bound English source material entry takes precedence over the old helper-derived format guidance. This format-only correction does not resolve other instruction or safety concerns. English names are not substituted into a Japanese-keyed lookup.

Everyday tools

Pens

Quantity: 1 per person

Format: Dark broad-tip pens or whiteboard markers

Check that the ink flows and place the pens where participants can reach them. Avoid pale-coloured pens.

Judgement-item sticky notes

Quantity: 4 per person

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised notes. Write “Judgement item” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Selection sticky notes

Quantity: 3 per person

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised notes. Write “Selection” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Sheets to prepare by hand

Uncertainty cards

Quantity: 6 per person

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Write a factor whose future is uncertain in the centre. Below it, create two endpoint fields: “Observable state at one end” and “Observable state at the opposite end”. Describe states that can actually be distinguished, rather than good and bad.

Surface for creating four futures from two uncertainties

Quantity: 1 sheet per group

Format: Source material specification: One two-axis cross sheet per group, approximately A2 size

Source-bound format display correction; the other fixed helper-derived guidance is unchanged.

Draw vertical and horizontal axes that cross in the centre. Write the two poles of the selected uncertainty A at the ends of the horizontal axis and the two poles of uncertainty B at the ends of the vertical axis. Leave room in the four quadrants for future descriptions and signs.

Sticky notes describing how life, decisions and resources change in four futures

Quantity: 12 per group

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

For each of the four futures, prepare one note each for “Life”, “Decisions” and “Resources”, for a total of 12 notes. At the top, identify the future and perspective; below, write only one specific observable state.

Disconfirming-evidence slips

Quantity: 4 per group

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised slips. Write “Disconfirming evidence” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Sign slips

Quantity: 4 per group

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised slips. Write “Sign” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Table for checking evidence gaps

Quantity: 1 sheet per group plus 1 for whole-group consolidation

Format: Source material specification: A3 evidence-gap boards: one per group and one for whole-group consolidation

Source-bound format display correction; the other fixed helper-derived guidance is unchanged.

For each claim to check, create fields headed “What is known”, “Missing evidence”, “Where to check” and “Deadline”.

Evidence-type cards

Quantity: 4 per group

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised cards. Write “Evidence type” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Surface for comparing options’ reversibility and cost

Quantity: 1 sheet per group plus 1 for whole-group consolidation

Format: Source material specification: A3 reversible/irreversible choice boards: one per group and one for whole-group consolidation

Source-bound format display correction; the other fixed helper-derived guidance is unchanged.

Label the vertical axis “Ease of reversal” and the horizontal axis “Cost of returning to the original state”, marking high and low at the ends of each axis. Place the options and leave room to add trial deadlines and withdrawal conditions.

Trial-deadline cards

Quantity: 1 per selected option

Format: Sticky notes around 75 × 75 mm, or A4 copy paper cut into four pieces.

Do not buy specialised cards. Write “Trial deadline” at the top of each paper slip. If participants write on them, use one item per slip and handwrite the necessary headings before the session starts.

Setup for each method

Scenario Matrix

  1. Groups of 3–5, with at least 3 people in each
  2. One island table per group for the two-axis cross sheet
  3. One whole-group surface collecting signals from all 4 futures

Evidence Gap Board

  1. One surface per group with existing evidence and missing evidence side by side, without a dividing line
  2. Space outside each group’s surface for items not needed this time, equal to 30% of that surface
  3. One wall surface for ordering gaps by the nearest decision deadline

Reversible Choice Board

  2. Space along the bottom edge for a strip showing trial order, at least 10 cm wide per group
  3. One wall surface where trial deadlines can be arranged by week to reveal concentrations

When to switch or stop

Fallbacks

3 or more uncertainty axes remain.

Narrow them to 2 based on impact and independence, and record the others as supporting factors.
