Decision-Making Framework: The PRISM Framework Explained

The PRISM
Framework
A better way to make better decisions — when the answer isn’t
obvious.
“The obvious answer is rarely the whole answer.”

Why good decisions go wrong
Intelligence helps us solve problems. Judgement
helps us decide which problems are worth
solving in the first place.
Poor judgement rarely comes from a lack of intelligence. More
often it comes from believing we’ve seen enough — and acting
on the first, most obvious answer.

Confirmation · Anchoring · Overconfidence · Recency · Status quo
· Groupthink
“Most problems arrive wearing
someone else’s clothes.”
An employee resigns looks like pay — may be
trust
Sales fall looks like price — may be relevance
Deliveries run late looks like logistics — may be
planning

Judgement is now a strategic capability
Leaders today operate amid data abundance, compressed
timeframes and rising scrutiny. The challenge is no longer
access to information — it is interpreting competing signals,
testing assumptions and making choices that stay sound
beyond the next quarter.
~40
%
of executives’ time goes on making decisions
— much of it felt to be poorly used.
McKinsey
Even capable leaders are pulled off course by bias — quietly and
systematically.
Harvard Business School
T H E S H I F T
Decision quality has become a core
organisational capability — not
merely a personal leadership trait.
PRISM doesn’t slow decisions down. It stops
leaders accelerating in the wrong direction.

T H E A P P R O A C H
Pause. Split the light. Then decide.
Every decision begins as white light — it arrives looking complete, convincing and urgent. A prism doesn’t change the
light; it reveals the colours already hidden inside it. Good judgement does the same for a decision.
01
Receive
Information arrives — a report, a
complaint, a request. Receiving it is
not the same as understanding it.
›
02
Reveal
Place the prism. Ask PRISM’s five
questions, challenge assumptions
and look for what’s missing.
›
03
Resolve
Decide with clarity, not certainty.
The goal is readiness — enough
understanding to act well.
PRISM’s five questions all live inside the middle stage — Reveal.

T H E C O R E I D E A
The White Light Principle
Shine white light through a prism and hidden colours appear.
The prism doesn’t change the light; it reveals what was
already there. Every significant choice behaves the same way
— it looks obvious only because we haven’t yet examined it
closely.
Most organisations debate solutions. Far fewer spend
time understanding the problem — and excellent
execution applied to poor judgement rarely ends well.
PRISM is the prism: it separates what we know from what we assume,
and expands understanding before narrowing the options.

P R I S M A T A G L A N C E
Five questions that reveal what you miss
P Purpose What am I really trying to achieve?
R Reality What do I know to be true?
I Insight What might I be missing?
S Stakeholders Who or what is affected?
M Maturity How will this decision age?
PRISM is not a decision-making framework — it is a thinking framework. It doesn’t replace your judgement. It
strengthens it.

P R I S M · 0 1 O F 0 5
P
Purpose
T H E F I R S T Q U E S T I O N
“What am I really trying to achieve?”
Refuse to confuse the visible problem with the real one. Targets — cut
cost, lift sales — are rarely the whole reason a decision matters.
I N P R A C T I C E
Keep asking “So that what?” until you reach the real purpose beneath the
target.
“
Purpose is the compass
for judgement. Point it
wrong, and perfect
execution only takes you
further from where you
meant to go.
A S K Y O U R S E L F
If I solved this perfectly, what would
actually improve?

P R I S M · 0 2 O F 0 5
R
Reality
T H E E V I D E N C E
“What do I know to be true?”
Separate facts from stories. Facts are observable; stories are created.
Know what you know, what you think, and what you’ve assumed — only
one is evidence.
I N P R A C T I C E
When you hear a confident claim, ask: “Is that a fact, or is that a story?” —
then, “How do we know?”
“
Consensus can feel
remarkably similar to
certainty. The two are
not the same.
“Revenue has fallen” is a fact. “Our
strategy isn’t working” is a story.

P R I S M · 0 3 O F 0 5
I
Insight
T H E C H A L L E N G E
“What might I be missing?”
Experience doesn’t automatically improve judgement — perspective
does. And perspective is something you deliberately collect.
I N P R A C T I C E
Ask the quietest person in the room. Seek the view that contradicts your own.
Call the customer no one wants to call.
“
Poor leaders collect
agreement. Good leaders
collect perspectives.
What do you see that I don’t?

P R I S M · 0 4 O F 0 5
S
Stakeholders
T H E C O N S E Q U E N C E S
“Who or what is affected?”
Every decision creates consequences beyond the problem it was meant
to solve. Empathy is part of judgement — not keeping everyone happy,
but understanding the impact.
I N P R A C T I C E
Map who is affected — customers, employees, suppliers, shareholders,
distributors, communities — then ask whose perspective you’ve missed.
“
The aim isn’t to give
everyone the same vote.
It’s to ensure no
important perspective is
ignored.
Who loses if we do this? Who else
has to live with this decision?

P R I S M · 0 5 O F 0 5
M
Maturity
T H E L O N G V I E W
“How will this decision age?”
Some decisions look sensible in the moment but age badly.
Consequences have half-lives — match your thinking to how long they
last, not to the size of the decision.
I N P R A C T I C E
Borrow tomorrow’s eyes. Picture the room in five years and ask: “What decision
do you hope we made?”
“
The future has no vote in
today’s meetings. Good
judgement gives it one
anyway.
How long will the consequences of
this decision continue to matter?

F R O M P R I N C I P L E T O P R A C T I C E
Applying PRISM in six steps
Use PRISM as a deliberate pause before commitment — a structured discipline for material choices, completed in twenty to
thirty minutes.
01
Define the decision
State the issue in one clear sentence.
A good frame invites exploration.
02
Purpose
What outcome are we genuinely
trying to achieve?
03
Reality
Separate facts, assumptions and
unknowns.
04
Insight
Invite disagreement and voices from
outside the room.
05
Stakeholders
Map who benefits, who bears the
cost, whose voice is absent.
06
Maturity
Will this still look like good judgement
in two years?

P R I S M I N P R A C T I C E
The answer behind the obvious answer
A manufacturer’s sales fell 14%. Within minutes the room reached for the usual answers — cut prices, run a promotion,
chase competitors. PRISM changed the conversation.
W H AT T H E F A C T S S H O W E D
−14% Sales
+32% Complaints
doubled Service turnover
delivering faster Competitors
W H AT P R I S M R E V E A L E D
Customers weren’t leaving over price. Unreliable delivery
had eroded their confidence — the problem was
operational and reputational, not commercial.
The decision: invest in service and reliability, not price. Sales
recovered, margins held, satisfaction rose.

W H E R E P R I S M B R E A K S D O W N
Five ways good thinking goes wrong
Each failure mode is a symptom of weak practice — and each has a discipline that restores it.
01 Starting with solutions
Discipline Clarify the choice and purpose before any solution is
debated.
02 Treating assumptions as facts Discipline Separate facts, assumptions and unknowns, visibly.
03 Confusing activity with progress Discipline Tie every initiative back to the agreed purpose.
04 Ignoring uncomfortable evidence Discipline Assign someone to argue the opposite case.
05 Forgetting time
Discipline Reserve PRISM for decisions of scale, reversibility and
lasting impact.

T H E Q U I C K R E F E R E N C E
The PRISM decision canvas
Run these five questions before the final recommendation is approved.
PRISM lens Core question In the room
Purpose What are we genuinely trying to achieve? Objectives, or solutions?
Reality What evidence supports our thinking? Which assumptions are untested?
Insight What perspectives are missing? Who sees this differently?
Stakeholders Who benefits and who bears the cost? Whose voice is absent?
Maturity How will this decision age? What precedent does this set?
Made a habit, these questions make assumptions visible and turn better judgement into a lasting competitive advantage.
