Definition
The GROW model is the most widely used coaching framework in the world. Developed by John Whitmore, Graham Alexander, and others in the 1980s, it organizes a coaching conversation into four stages: Goal (clarify the session objective and the ultimate goal), Reality (explore the current situation honestly), Options (generate the greatest possible number of alternatives without judging), and Will (commit to concrete actions before leaving the session). GROW provides structure without rigidity — it is a map, not a script.
How it's used
The Goal stage is more complex than it appears. There are two levels: the session goal ("What do you want to achieve in this conversation?") and the ultimate goal ("What outcome do you want to achieve in your life or work?"). A well-formulated goal is specific, measurable, and belongs to the client — not the coach.
In the Reality stage, the coach helps the client see their current situation accurately, without softening or dramatizing it. Useful questions: "What is happening exactly?", "What have you tried so far?", "What has worked, even partially?"
Options is the most creative stage: the coach invites the client to generate all possible options before evaluating them. Quantity matters — when the client says "I have no options," the coach's work is to demonstrate that there are more.
Will closes the session with specific commitments: What are you going to do? When? How will you know you did it? On a scale of 1-10, how likely are you to do it? If the probability is low, explore what obstacles exist.
When to apply
GROW works in individual coaching, in manager-report development conversations, in 1-on-1s, and in team coaching. It is especially effective when the client already has the necessary skills and what they lack is clarity or a plan.
Historical origin
John Whitmore developed the GROW model in the 1980s from his work in sports and business coaching, influenced by Tim Gallwey's work on the "Inner Game." His book Coaching for Performance (1992) was the first systematic treatment of the model and remains a central reference in the field.
How CauceOS supports it
CauceOS includes a GROW note template that records the client's responses at each stage and the commitments agreed at the end of the session. Alerts can be configured to signal when the conversation is stuck in a stage (for example, repeatedly returning to Reality without advancing to Options).
