How to define job titles in a small business using a three-level matrix

Executive overview

Small teams can't rely on seniority tiers to signal hierarchy — one support person can't be junior and senior. A simple three-level matrix clarifies who is responsible for what, at what scope.

The framework assigns each role a level (coordinator, manager, lead) based on how far their ownership extends across five dimensions: when, how, what, who, and why.

Ownership scope — not seniority — defines the title.

The three levels and what they own

• Coordinator — owns their own execution: their deadlines, working hours, and how they do their specific tasks
• Manager — owns themselves plus everyone involved in a process or project; shapes what steps exist in that process
• Lead — owns the full function: all stakeholders, future planning, team composition, and the organisational "why"

Building the full title

• Combine the level with the functional area: marketing coordinator, customer support manager, operations lead
• The function label comes from what the person is actually responsible for, not a generic department name
• The same matrix works as the team grows — titles stay accurate without needing a redesign

The five dimensions of ownership

1. When — coordinator owns their own deadlines; manager owns project timelines across contributors; lead owns broad initiative sequencing
2. How — all three levels own how they execute, but scope expands upward; leads own process quality across the whole function
3. What — coordinators execute pre-scoped work; managers define and refine the steps in their process; leads set priorities across areas
4. Who — coordinators are self-responsible only; managers influence who is involved in their process; leads control team composition overall
5. Why — everyone should understand why their work matters, but leads carry responsibility for setting and cascading that clarity

Applying the matrix

• Choose three level names that fit your culture — coordinator/manager/lead is one option; assistant/specialist/head-of is another
• Fill out the full matrix for your chosen titles so the definitions are explicit, not assumed
• "Head of marketing" means different things at different companies — the matrix makes your definition concrete
