3.5Combining methods by context
The essentials in 30 seconds
- No universal tool: each method has its favorite ground (frame, generate, decide…).
- Cues: frame (5W1H, 5 whys), generate (brainstorming, SCAMPER), group (6 hats), sort (level 4).
- Sequence: frame → diverge → converge → prototype → test; maturity = the right tool at the right moment.
Running case — Sara sequences on satisfaction
Falling reception satisfaction: Sara refuses to brainstorm right away. She sequences: 5W1H + 5 whys (frame the real cause), a How-might-we question, brainstorming + SCAMPER (generate), impact/feasibility matrix (decide, level 4), prototype tested with users. Each phase mobilizes the fitting tool — never the reverse.
Last episode of cases 3.1-3.4 — Sara assembles methods into a complete approach.
1. No universal tool
You now know many methods. A central question arises: which method when? There is no universal tool: each method has its favorite ground.
Expertise is choosing the right one by context and often sequencing them. A technical problem, an open creative challenge, a team block or a hard decision do not call for the same tools.
2. Cues by need
To frame: 5W1H (describe), 5 whys (single cause), Ishikawa (multiple causes), HMW restating. To generate: brainstorming/brainwriting, SCAMPER (transform), associations (breakthrough), mind map (explore).
To think as a group: the six hats. To innovate around the user: Design Thinking. To sort and decide: grouping and matrices (level 4).
3. A complete approach
Above all, methods combine and sequence: first frame (understand the real problem), then diverge (generate widely), then converge (sort, decide), then prototype and test.
Creative maturity is not knowing a thousand methods, but mobilizing the right one at the right moment. With experience, you feel which tool fits — like a craftsperson choosing the right tool for each task.
🔎 Concrete example — Sequencing on a real problem
Falling customer satisfaction: a complete approach.
1. Frame: 5W1H + 5 whys (real cause).
2. Restate: How might we…?
3. Generate: brainstorming + SCAMPER.
4. Decide: impact/feasibility matrix.
5. Test: prototype with customers.Result: each phase mobilizes the fitting tool.
Reflex: always frame before generating.
Section vocabulary
- Method choice
- Selecting the tool fitting the problem type (technical, creative, organizational) and context.
Simple example: Sara picks the 6 hats because the block is a group debate.
What it is not: applying your favorite tool to every problem.
Reflex: name the need (frame? generate? decide?) before the tool.
- Method sequencing
- Articulating several tools into a complete approach (frame → diverge → converge → prototype → test).
Simple example: 5W1H → HMW → brainstorming → matrix → prototype.
What it is not: an isolated brainstorming on an unframed problem.
Reflex: write the chain before starting: phases + tools.
- Favorite ground
- The type of situation where a given method is most effective.
Simple example: The 5 whys on a single cause; Ishikawa on multiple causes.
What it is not: wanting to do everything with SCAMPER, even framing.
Reflex: for each tool you know: it excels when…
- Complete approach
- A process linking problem understanding, idea generation, decision and test.
Simple example: Sara's end-to-end path on satisfaction.
What it is not: stopping at ideas without deciding or testing.
Reflex: no finished approach without a tested prototype.
- Creative judgment
- The ability, gained with experience, to mobilize the right tool at the right moment.
Simple example: Sara feels lateral is needed, not a 6th brainstorming.
What it is not: collecting methods without practicing any.
Reflex: after each case: which tool helped, and why?
In practice — Combining methods by context
- Identify the type of need: frame, generate, structure group thinking, or decide.
- Pick the fitting tool (5W1H/5 whys/Ishikawa to frame; brainstorming/SCAMPER/analogies to generate; 6 hats to think as a group…).
- Sequence: frame → diverge (generate) → converge (sort/decide) → prototype → test.
- Develop your judgment with practice: feel which tool fits which problem.
Ready-to-say script — announcing the sequence (30 s)
We do not generate right away: first we frame the real cause in 20 minutes (5W1H + whys), restate as a how-might-we, then generate widely, sort with the matrix and test a prototype. Each phase has its tool — we start by framing.
To say at the start of a session: phases, tools and the frame-first rule displayed.
Copy-paste template — sequencing plan
PROBLEM: _______________
FRAME (tool + 20 min): _______________
HMW RESTATING: _______________
GENERATE (tool + time): _______________
DECIDE (matrix / vote): _______________
TEST (prototype + who + when): _______________Urgent (1h)
Express version: 15 min frame, 20 min generate, 15 min sort, 10 min prototype — one tool per phase.
User topic
Add Design Thinking + empathy map first: without a real need, the chain starts wrong.
Group decision
Insert the 6 hats before the matrix: they calm things down, then the matrix decides rationally.
Hard block
Insert a lateral detour (reversal, chance) between framing and generating to break the rut.
✓ Best practices
- Always start by framing, before seeking solutions.
- Think in phases (frame / generate / decide / test) rather than in THE method.
- Master a few tools well rather than skimming a thousand.
✗ Common pitfalls
- Jumping to generation on a poorly understood problem.
- Applying a method outside its favorite ground.
- Collecting methods without truly practicing any.
Key takeaways
- There is no universal tool: each method has its favorite ground.
- Cues: frame (5W1H, 5 whys, Ishikawa, HMW), generate (brainstorming, SCAMPER, analogies), think as a group (6 hats), innovate (Design Thinking), decide (matrices).
- Methods combine and sequence: frame → diverge → converge → prototype → test.
- Creative maturity = mobilizing the right tool at the right moment (judgment gained with practice).
48h challenge — apply tomorrow
On 1 real problem, write your frame → generate → decide → test chain (template above) and launch at least the 20-min framing phase.
- I can cite 1 tool per phase (frame, generate, decide, test).
- I wrote 1 complete chain on a real case.
- I framed (or planned) before any generation.
Frequently asked questions
Which method to start with facing a problem?
Almost always start by FRAMING the problem before seeking solutions. Describe the situation (5W1H), target the real problem, seek causes (5 whys, Ishikawa), restate as a How might we…? question. Then choose next by nature: generate, innovate around a user, group decision.
Must you master all these methods?
No. Creative maturity is not knowing a thousand methods, but mastering a few well and mobilizing the right one at the right moment: one to frame, one to generate, HMW, one matrix, and the Design Thinking idea as a framework.
