ACE distinguishes three purposes that often become tangled. Appreciation says that effort, value, or impact is seen and helps people remain engaged. Coaching supplies information intended to improve the work or the person. Evaluation rates or ranks performance against expectations or standards and answers questions such as whether someone is on track. People need all three over time, but not necessarily at the same moment. A giver should clarify what would be useful at the current stage rather than responding to a broad request for “feedback.” A receiver can likewise specify the type wanted, reducing the risk that coaching is heard as condemnation or that encouragement arrives when a decision is required.
Origin
Heen presented ACE—appreciation, coaching, and evaluation—as a memorable framework from her feedback work on The Tim Ferriss Show.
Core principles
- 01People need all three feedback types over time
- 02Different stages call for different feedback
- 03Appreciation sustains engagement
- 04Coaching drives improvement
- 05Evaluation locates performance against a standard
How to run it
- 1
Diagnose the need
Ask what would be helpful at this stage. Determine whether the person needs encouragement, improvement guidance, or a judgment against standards.
Pro tip Do not assume a request for feedback means all three types.
- 2
Name the type
Make explicit whether the exchange is appreciation, coaching, or evaluation so the parties share the same purpose.
Watch out Coaching contains an implicit evaluation that something could improve, so identity reactions may still arise.
- 3
Deliver for that purpose
Offer specific recognition, actionable guidance, or a clear comparison with expectations according to the selected type.
Pro tip Specific appreciation sounds more genuine than a generic compliment.
- 4
Balance over time
Notice which feedback types the relationship or team has been short on and deliberately restore them.
Watch out A steady diet of evaluation without appreciation or coaching can make feedback feel like constant judgment.
In the wild
Tim Ferriss asked Steven Pressfield to tear apart very early fiction. Pressfield instead said he had read it, wanted more, and told Ferriss to keep going. Ferriss inferred that detailed coaching and evaluation were premature; appreciation was what would sustain progress at that stage.
→ The writer continued rather than becoming stalled by premature critique.
Common mistakes
Asking only for feedback
The broad request leaves the giver guessing about honesty, preparation, purpose, and the receiver's current need.
Confusing coaching with evaluation
Improvement guidance and judgment against a standard are related but produce different emotional reactions and answer different questions.
Is it for you?
Best for
Managers, collaborators, teachers, and creators asking for or providing feedback.
Not ideal for
Conversations where the parties are unwilling to clarify the purpose of the exchange.
From the transcript
“Easy way to remember them is ACE, A-C-E, appreciation, coaching and evaluation. We need all three.”
“Coaching is anything designed to help it be better, help me be better.”
“So yes, evaluation is rating or ranking against some set of expectations or standards how you measure up.”
