01

Prerequisite

What needs to be finished first

Complete firstBounded subject

The scope and purpose of Design Charrette are stated as a concrete question.

Without scope, charrette design package becomes arbitrary.
Complete firstAccess to relevant perspectives

Design brief, user and domain requirements, evaluation criteria and domain decision makers are available.

Without these perspectives, central claims in charrette design package remain unsupported.
02

Preparation

What needs to be ready before start

Materials

Design brief, user and domain requirements, evaluation criteria, shared workspace, source links, and decision log.

People / roles

Sponsor · facilitator · multidisciplinary designers · affected users

Pre-read

Collect Design brief, user and domain requirements, evaluation criteria in advance and mark open assumptions.

Time needed

3 hours to 2 days

Setup

Prepare parallel sketches, criteria-based critique, and iterative synthesis in timeboxes visibly and calibrate assessment terms before starting.

03

Core question

The one question this method answers

Which integrated design option best satisfies the agreed criteria?

04

Flow

Phases with goal, actions, output and pitfall

A charrette combines a compact brief, parallel designs, structured critique, and revision. Criteria and decision authority are clarified before rounds.

charrette design package

Fictional worked example

parallel sketches, criteria-based critique, and iterative synthesis in timeboxes as a precise working structure with a fictional example.

Brief

Service hand-off: case summary

Service-centre hand-off.

Criteria

Measure: under two minutes

<2 min; audit trail; no duplicate entry.

Option/Critique

Option B: timeline with audit trail

B audits but duplicates entry.

Synthesis

Synthesis AB: timeline plus case data

B timeline + A case data; prototype test.

  1. 1

    Brief

    Brief

    Goal

    Produce working brief so the core question “Which integrated design option best satisfies the agreed criteria?” can be answered with stronger support.

    Inputs for this step

    • Design brief
    • user and domain requirements
    • evaluation criteria

    Actions

    • Confirm problem, users, boundaries, and criteria.
    • Record source, rationale, and open uncertainty directly in working brief.

    Output

    working brief

    working brief · source · uncertainty · next decision

    Quality check

    Are conflicting criteria explicit?

    Pitfall

    Critique judges taste rather than criteria, or the sponsor decides during ideation. Keep criteria visible, frame critique as observation and effect, and separate the decision phase.

    Timing: 10–20 minutes

  2. 2

    Design

    Design

    Goal

    Produce design options so the core question “Which integrated design option best satisfies the agreed criteria?” can be answered with stronger support.

    Inputs for this step

    • working brief
    • user and domain requirements
    • evaluation criteria

    Actions

    • Develop several rough options in parallel.
    • Record source, rationale, and open uncertainty directly in design options.

    Output

    design options

    design options · source · uncertainty · next decision

    Quality check

    Are options comparable and sufficiently distinct?

    Pitfall

    Critique judges taste rather than criteria, or the sponsor decides during ideation. Keep criteria visible, frame critique as observation and effect, and separate the decision phase.

    Timing: 10–20 minutes

  3. 3

    Critique

    Critique

    Goal

    Produce critique record so the core question “Which integrated design option best satisfies the agreed criteria?” can be answered with stronger support.

    Inputs for this step

    • design options
    • user and domain requirements
    • evaluation criteria

    Actions

    • Review options silently against criteria.
    • Record source, rationale, and open uncertainty directly in critique record.

    Output

    critique record

    critique record · source · uncertainty · next decision

    Quality check

    Does feedback link observation and effect?

    Pitfall

    Critique judges taste rather than criteria, or the sponsor decides during ideation. Keep criteria visible, frame critique as observation and effect, and separate the decision phase.

    Timing: 10–20 minutes

  4. 4

    Synthesize

    Synthesize

    Goal

    Produce design package so the core question “Which integrated design option best satisfies the agreed criteria?” can be answered with stronger support.

    Inputs for this step

    • critique record
    • user and domain requirements
    • evaluation criteria

    Actions

    • Combine strengths, resolve conflicts, and plan an open test.
    • Record source, rationale, and open uncertainty directly in design package.

    Output

    design package

    design package · source · uncertainty · next decision

    Quality check

    Are decision and open risks documented?

    Pitfall

    Critique judges taste rather than criteria, or the sponsor decides during ideation. Keep criteria visible, frame critique as observation and effect, and separate the decision phase.

    Timing: 10–20 minutes

Example output

Concrete filled scenario, fictional example

Fictional example for orientation. Counts and timings describe this case and are not universal requirements.

design-charrette-beispiel.md

Concrete filled scenario, fictional example

Criteria: hand-off under two minutes, audit trail, no duplicate entry. Three teams sketch separately. Critique finds option B supports audit but duplicates entry. Synthesis combines B's timeline with A's shared case data.
