English session plan

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

Preparation: More preparation. Facilitation team: Three operating roles.

What this session can decide

Create a future vision as a hypothesis and actions for checking it. Do not use this as a forecast, budget commitment, or approval of a business plan.

Outside its scope

  • Do not predict the future.
  • Do not treat one future vision as inevitable.
  • Do not promise unapproved investment.

Primary caution: Do not predict the future.

Before starting

Question and scope
Make a desired future concrete, then work backwards to the conditions for reaching it and actions to start now. Before starting, state the subject and time period in one sentence.
What this session decides
Create a future vision as a hypothesis and actions for checking it. Do not use this as a forecast, budget commitment, or approval of a business plan.
Output recipient
The Recorder stores the final checking actions with owners and deadlines to test future hypotheses on a small scale.
Participation and information boundaries
Offer speaking, writing, or passing as participation choices. Keep personal information, confidential information, and attribute-based evaluation off the record surface.
Operating roles
Assign Lead facilitator, Recorder, and Timekeeper before starting, and confirm who announces switching and stopping.
Next review
Set a review date, viewers, and the person responsible for the next decision on the checking actions with owners and deadlines.

Who takes responsibility

Lead facilitator

Keep Backcast from a Desired Future within its purpose and exclusions, and announce the start and end of each stage.

From before the start through the end

Recorder

Record the concrete future vision and observation indicators, backcast map of milestones, prerequisites, and actions, and checking actions with owners and deadlines at each stage, then hand them to the recipient at the end.

From preparing record surfaces before the start through storage after the end

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

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. 0–93 minutes

    Describe the desired future state

    Method: Desired-Future Image Workshop · 0–90 minutes. Transition: 90–93 minutes (3 minutes).

    Define the target year and stakeholders, then write what happens, what decreases, and who experiences what. Separate aspirations, assumptions, and observable signs.

    Responsible: Lead facilitator; Recorder; Timekeeper

    Output: Concrete future vision and observation indicators

    Handoff: Pass the future vision and signs to the backcasting work.

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

  2. 93–186 minutes

    Work backwards from the destination conditions to the present

    Method: Backcasting · 93–183 minutes. Transition: 183–186 minutes (3 minutes).

    Place necessary milestones and prerequisites from the future vision back towards the present. Add actors, checking indicators, and branches in case of failure to each milestone.

    Responsible: Lead facilitator; Recorder; Timekeeper

    Output: Backcast map of milestones, prerequisites, and actions

    Handoff: Pass actions that can begin now to the smallest commitments.

    This stage is not marked as shortenable.

  3. 196–224 minutes

    Choose the smallest action to begin checking

    Method: Smallest Commitment Chain · 196–221 minutes. Transition: 221–224 minutes (3 minutes).

    Choose checking actions that can begin without additional authority or a large budget. Record the owner, deadline, evidence sought, and date for deciding whether to continue.

    Responsible: Lead facilitator; Recorder; Timekeeper

    Output: Checking actions with owners and deadlines

    Handoff: Pass the future vision, backcast map, and checking actions to the responsible person.

    This stage is not marked as shortenable.

What is retained and who receives it

Concrete future vision and observation indicators

Owner: Recorder

Turn abstract aspirations into states that can be checked.

Backcast map of milestones, prerequisites, and actions

Owner: Recorder

Connect the long-term vision to immediate decisions.

Checking actions with owners and deadlines

Owner: Recorder

Test future hypotheses on a small scale.

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

Writing implements

Quantity: 1 per person

Format: Dark broad-tip pens or whiteboard markers

Check that ink flows and place them within participants' reach. Avoid pale-coloured pens.

Connecting tape

Quantity: 1 roll per group

Format: Low-tack masking tape

Check removability on an inconspicuous part of the floor or wall. Keep edges flat and do not obstruct routes.

Dark writing implements

Quantity: 1 per person

Format: Dark broad-tip pens or whiteboard markers

Check that ink flows and place them within participants' reach. Avoid pale-coloured pens.

Sheets to prepare by hand

Future-window sheet

Write Evidence at the top, with a Seen or heard field below it. Leave room for one entry per card.

Difference cards

Quantity: 3 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Do not buy special cards; write Difference at the top of paper pieces. If participants fill them in, put one entry on each card and handwrite the necessary headings before starting.

Observation sheets

Quantity: 3 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Write Observation at the top, with an Owner field below it. Leave room for one entry per sheet.

Future completion-state cards

Quantity: 1 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Write Future completion state at the top, with an Evidence field below it. Leave room for one entry per card.

Cards for the gap from the present

Quantity: 4 per person

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Create Present and Future fields on one sheet. Write a heading for each field rather than relying on colour alone.

Condition cards

Quantity: 6 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Arrows connecting preceding and subsequent conditions, with an owner field

Quantity: 8 per group

Format: Masking tape or A4 copy paper cut into long strips

Draw an arrow from the preceding condition to the next and write Prerequisite for this connection and Person responsible for checking that prerequisite.

Markers showing the scope for influencing conditions

Quantity: 18 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

Write We can influence this ourselves, We can influence this with others, and An external decision is needed on separate pieces of paper, preparing enough of each type. Distinguish them by written headings even when using the same colour.

First-action sheets

Quantity: 2 per group

Format: Sticky notes about 75 × 75 mm, or A4 copy paper cut into 4 pieces

When to switch or stop

Fallbacks

There are more than 6 future visions.

Bundle the states they share and retain two conflicting visions separately.

Method guide: Desired-Future Image Workshop

Stop conditions

A future hypothesis is treated as a confirmed forecast or investment guarantee.
Return to labelling it as a hypothesis and define the additional evidence needed for a decision.
A plan imposes serious burdens on absent affected parties.
Stop turning it into a plan and check with those parties first.
