# Category Definition & Modeling

## Purpose

Models a product or business relative to market categories: either
associating it with an existing category, expanding or redefining an
existing category, or assessing the creation of an entirely new category.
A category decision isn't just branding — it directly shapes what the
customer compares the product to, who is perceived as a competitor, and
how large a share of the market's value can accrue to the category leader.

## Anchored in research

- Ramadan, A., Peterson, D., Lochhead, C. & Maney, K. (2016), *Play Bigger:
  How Pirates, Dreamers, and Innovators Create and Dominate Markets* — the
  Category Design school of thought: category kingship (the Category King)
  — the company that builds and owns a new category captures a
  disproportionate share of the category's value; the "Lightning Strike"
  concept for launching a category; the flywheel effect that reinforces
  category leadership over time.
- Kim, W. C. & Mauborgne, R. (2005), *Blue Ocean Strategy* — creating
  uncontested market space by separating value innovation from existing
  category boundaries; the four-action grid (eliminate/reduce/raise/create).
- Ries, A. & Trout, J., positioning theory — how a category shapes the
  customer's mental image and frame of comparison before the product's
  features are even evaluated.

## Method

1. **Map the existing categories** the product or business could plausibly
   be associated with — what would the customer already intuitively
   compare this to?
2. **Assess three alternative category strategies**, following Play
   Bigger's framing of the category-design spectrum:
   - **(a) Associate with an existing category.** Leverage ready-made
     customer understanding and buying logic, but compete directly against
     established players on the category's own terms. The fastest and
     cheapest route — and the default unless there's a specific reason to
     leave it.
   - **(b) Expand or redefine an existing category.** Introduce a new
     dimension or sub-category that partially shifts the frame of
     comparison in your favor. A medium resource commitment; often the
     right move when the existing category's terms structurally favor an
     incumbent.
   - **(c) Create an entirely new category.** Detach the product from
     existing frames of comparison. High risk and a long cycle (requires
     significant market education), but a successful "Category King," per
     Play Bigger, captures a disproportionately large share of the
     category's economic value compared to the #2 and #3 players — which
     is the core argument for accepting the higher cost and risk.
3. **If you're considering a new or expanded category, run the Lightning
   Strike test.** Play Bigger's launch concept asks: is there a single,
   concentrated moment (a launch event, a category-naming announcement, a
   flagship customer story) that can establish the category point of view
   in the market's mind at once, rather than trickling it out gradually?
   A category strategy with no plausible Lightning Strike moment is harder
   to pull off than the resource estimate in step 4 alone would suggest.
4. **Stress-test the category point of view with Blue Ocean's four-action
   grid** — what industry givens can be **eliminated**, what can be
   **reduced** clearly below the industry standard, what can be **raised**
   clearly above it, and what entirely **new** factor can be **created**?
   The pattern of answers should read as a coherent story, not a random
   list — that story is the category's point of view.
5. **Assess the resource requirement of the category decision honestly:**
   associating with an existing category is fastest and cheapest,
   expansion is medium-effort, creating a new category requires sustained
   market education and significant communication investment over multiple
   years, not quarters.
6. **Define a category name and description** that crystallizes the chosen
   position in the customer's mind — the category name is part of the
   strategy, not just branding.
7. **Identify the category's flywheel** — per Play Bigger, what mechanism
   reinforces category leadership over time (network effects, accumulating
   data, brand recall, breadth of distribution)? A category strategy
   without an identifiable flywheel risks winning the launch and losing
   the category to a fast follower.
8. **Keep the category decision a living hypothesis** — the market's
   reaction (competitors' positioning, customer language, analyst
   classification) validates or challenges the chosen category strategy
   over time; don't lock in a category too early without a market signal.

## What this skill does NOT do

- Doesn't guarantee the success of a new category — creating a new category
  is a high-risk strategy whose success requires significant resources and
  sustained commitment (Play Bigger's own examples are survivorship-biased
  toward winners; most category creation attempts don't reach Category King
  status).
- Doesn't make the final category decision for you — it structures the
  alternatives and their risk/resource profile to support a human decision.
- Doesn't replace market research into the customer's current mental
  associations — the decision needs to be validated with real customer
  understanding, not internal deliberation alone.

## Refinement notes

Areas to keep deepening with real practice:

- your own rules of thumb for when creating a new category is worthwhile
  for research-based/deep-tech opportunities vs. when it isn't
- concrete templates (into `../../references/`)
- reference cases / your own examples of a successful or failed category
  decision
- what this skill deliberately does *not* do (guardrails, common mistakes) —
  add to the list above

Once this section is filled in and validated in practice, update the
`maturity` field in `skills_index.json` to `draft`, `validated`, or
`canonical` (see `../../../meta/maturity_levels.md`). **Don't add new
fields to the frontmatter** — `name` and `description` are the only ones
allowed (see `../../../meta/frontmatter_schema.md`).
