A progression of questions
SPIN stands for Situation, Problem, Implication and Need-payoff, translated here as Situation, Problem, Implication and utility of a solution. Huthwaite is the source of the method. Situation questions establish the useful context. Problem questions explore a perceived difficulty, without inventing it. Implication questions seek the concrete consequences of that difficulty. Need-payoff questions invite the client to express what an improvement would bring them. The method does not impose four questions on every exchange nor a mechanical order. Prepare what you already know to limit unnecessary situation questions. A simple request for floor plans deserves an immediate answer first, not an imposed full interview.
Fictional example
Situation: "How do you use your home today?" Problem: "What is bothering you?" Implication: "What impact does that have on your daily routine?" Need-payoff: "What would a separate space change for you?"
A question must serve the understanding of the project.
Explore consequences without amplifying fear
An implication is not a threat. It helps understand the frequency, effects, and importance of a problem expressed by the client. If commutes are tiring, ask about their impact on schedules or organisation, without predicting deteriorating health or dramatising the issue. Allow for a response that minimises the problem as well. Rephrase the consequences and check their accuracy. The difference with a problem question lies in the level: "What is bothering you?" identifies the difficulty; "What does it prevent you from doing?" explores its impact. If the topic becomes sensitive or irrelevant to the project, return to the necessary information. Do not exploit a vulnerability to accelerate commitment.
Fictional example
"The commute takes longer than you would like. Which parts of your week does this affect?" allows the person to describe the actual impact.
The importance of the problem is expressed by the client.
Have the value articulated and summarise
The need-payoff question seeks the value of an improvement before pitching a specific property. "If you could entertain guests without moving your workspace, what difference would that make?" helps define a benefit. It is neither a promise that the available property solves everything, nor a request for a signature. Then link the answers to selection criteria and evidence to obtain. Conclude with a summary that the client can correct: context, difficulty, consequences, desired outcome, unknowns, and next action. Combine SPIN with SONCAS as a hypothesis framework and CAP/CAB to present a documented response. The methods complement each other, but replace neither listening nor thorough checking of the file.
Fictional example
The client wishes to reduce interruptions while working from home. The summary becomes a criterion for a separate space and a verification of actual usage, not simply "wants something bigger".
Transform the conversation into criteria and actions.
Your practical application work
In Meknes, a client works from home and regularly hosts family. He says he lacks peace and quiet but has not yet defined what he wishes to change.

- An implication question without dramatisation
