In short
Your capstone begins with research: a theme narrow enough to make, a reading plan, material studies and market notes, all in a dated evidence file that distinguishes what you found, what others say and what you have smelled yourself. Level 12 takes one fragrance from idea to documented case study. It is a personal learning project. Completing it shows what you did and does not confer a qualification.
What you will learn
- Choose a capstone theme you can research and make
- Build a dated evidence file with sources
- Separate evidence, opinion and your own observation

How the capstone runs
| Stage | Output |
|---|---|
| Research (this lesson) | Evidence file |
| Concept | Concept statement and its tests |
| Formula and log | A traceable sequence of versions |
| Evaluation | A plan and its results |
| Cost and regulatory review | A costing and a marked-up review |
| Documentation | A standard formula file |
| Portfolio and case study | A work others can read |
Choosing the theme
A good theme has three properties: it interests you enough to keep going through a dull stage, you can reach the materials, and you can tell whether you have succeeded. Compare:
- Too broad: "The history of rose."
- Better: "A rose heart without a heavy honeyed effect, at a stated cost, for daytime wear."
- Too dependent: "A formula using a captive I cannot buy."
What goes in the evidence file
- Reading. Sources, each with a date, a one-line summary and how much you trust it.
- Reference fragrances. Those you have actually smelled, with your notes.
- Material studies. Cards for your main materials, following evaluating a material.
- Technical notes. Restrictions on likely materials, recorded with amendment and date.
- Practical limits. Budget, equipment, time and who can help you evaluate.
- Open questions. What you don't know yet, and how you would find out.
Grading your evidence
Label each statement so you can tell later what it rests on.
| Label | Meaning | Example |
|---|---|---|
| Primary | Law, standard, supplier document or published study you have read | A dated IFRA Standard |
| Secondary | Someone's summary | A blog or book |
| Observed | You smelled or measured it | Your time course |
| Opinion | A judgment, yours or another's | "This reads as old-fashioned" |
Do not upgrade one label to another by repetition. You can use the Research and Innovation track's critical reading lesson if your theme depends on published science.
Stopping
Research can become a way to avoid composing. Set a limit: for example, two weeks or twenty sources, whichever comes first. Stop when you can write a concept and a first draft plan. You will come back with better questions once something exists on a strip.
Practical exercise: Capstone evidence file
- Write your theme in one sentence, with a way to tell if you have succeeded.
- Build the file: at least ten sources with labels, five reference fragrances you have smelled, and cards for five materials.
- Write your practical limits honestly.
- List your top five open questions, and say how you plan to answer them.
- Ask someone to read the theme, and tell you what they think you are making.
You have done this well if every statement has a label and a date, you know what you cannot reach, and the theme is small enough to complete.
Common mistakes
- Choosing an impressive theme you can't test. Choose what you can make.
- Reading without smelling. You need both.
- Researching for ever. Set a stopping date.
