In short
At the highest level a perfumer's work includes other people's work: briefing perfumers, running critique that makes their trials better, keeping decisions reviewable, and presenting the result as a submission a client can trust. Each is a skill with a method. A good brief states intent and criteria and leaves the method to the maker; good critique is specific and testable; a decision log makes choices answerable; a submission dossier shows its evidence and its limits.
What you will learn
- Brief another perfumer so that their work answers your intent without copying your method
- Run a critique session that improves work and keeps people willing to bring it
- Keep a decision log that makes a project's choices reviewable
- Assemble a professional submission dossier with rationale, evidence and constraints

Before you start
This builds on evaluation in development, your mod tree project and Level 12's case study.
Briefing others
Write the brief you would want: the intent in a sentence, the fixed constraints, the benchmarks, how the work will be judged and when. Leave out your own solution. A perfumer given your method produces your perfume, worse; given your intent, they may produce something better.
Critique that improves work
- Separate observation from preference. "At one hour the heart arrives before the citrus has gone" is an observation; "I'd like it warmer" is a preference, labeled as one.
- Tie it to the brief. Critique against what was asked, not against what you would have done.
- Propose a test. "Try halving the bridge and see if the gap closes" gives the maker something to do.
- Protect the room. People bring unfinished work only where it is safe to; critique the trial, never the person.
The decision log
For each significant choice — which direction to pursue, which submission to send, which material to replace — record the date, the options, the evidence and who decided. It turns "why did we do that?" from memory into record, and it is the professional form of the hypothesis log and mod tree.
The submission dossier
- The brief as you understood it, with your questions and the answers.
- The rationale: architecture, differentiation, how it answers the open territory.
- Evidence: what was tested, how, with what result and what panel size.
- Constraints met: cost in use, concentration, and the regulatory review status — stated as what a qualified assessor has or has not confirmed.
- Open questions and what the next round would test.
Limitations
No method replaces taste or the client's judgment, and leadership in large organizations involves much that a course cannot teach. What can be taught is the discipline that makes creative decisions reviewable.
Research application
Does structured critique produce better outcomes than open discussion, by blind evaluation of the resulting trials? A small, repeated comparison within a working group would test it.
Practical exercise: Lead one small creative round
- Write a brief and give it to at least one other perfumer (or to yourself, set aside for a fortnight, if no one is available, and say so).
- Run a critique session on the trials using the four rules above, and record it.
- Keep a decision log from brief to selection.
- Assemble the submission dossier for the selected trial.
You have done this well if the brief contains no formula, the critique record separates observation from preference and proposes tests, the log covers every significant choice with its evidence, and the dossier states its open questions and its regulatory status honestly.
Common mistakes
- Briefing with your own solution.
- Critique as rewriting.
- A dossier with no limits. It will not be believed.
Key terms
- Decision log
- A dated record of each significant choice in a project, the options considered, the evidence used and who decided, so the reasoning can be reviewed later.
- Submission dossier
- The package that accompanies a fragrance submission: the brief's interpretation, the rationale, the evidence of testing, the constraints met and the open questions.
