Defining roles and responsibilities in a small business: a three-step framework

Executive overview

Copying generic job descriptions from the internet produces roles that don't match what your business actually needs. The result: new hires lack clear direction, and tasks fall through the cracks.

Start from what your business does, not from what other businesses call their roles. Map every process first, then cluster them into roles — you can't miss anything if you work backwards from the full picture.

The process org chart is the foundation: define all business processes first, then assign ownership.

Step 1: Map every process in a process org chart

• List everything your business needs to do — every task, every recurring activity.
• Organise these into an org-style chart, with the overall business goal at the top and increasing specificity below.
• Each box represents a process, which is also an area of responsibility.
• Some areas are broad (e.g. "get clients"); others are granular (e.g. "edit YouTube video").
• This chart is a one-time build; once done, it becomes a reusable reference for every future hire.

Step 2: Circle and cluster processes into roles

• Use colour-coded markers to group processes that belong to the same person.
• One colour = one role. The boxes inside that colour = the responsibilities for that role.
• Grouping logic: which tasks would you want owned by the same human?
• In small businesses, people own multiple processes; colours reflect that multi-role reality.
• This method guarantees full coverage — no tasks left unassigned and no gaps discovered after hiring.

Step 3: Maintain two companion charts

Job role org chart

• Extracts all colour-coded roles from the process org chart into a standalone chart.
• Shows every role, who it reports to, and how roles relate to each other.
• In small businesses, one person often holds multiple roles — this chart makes that visible.
• More useful day-to-day than a traditional org chart because it reflects what people actually do.

Human (HR) org chart

• Traditional chart: each person appears once, showing their primary title and reporting line.
• Useful for performance reviews, one-on-ones, and HR structure.
• Less accurate for small teams but necessary for formal people management.

Bonus: how to identify your next hire

• Look at a team member carrying four job roles — consider splitting them.
• They keep two roles; the other two become a new job title you hire for.
• Ask existing team members which of their current responsibilities they like least or struggle with most.
• Those answers identify which roles to remove from their plate and recruit separately.
• Job roles (what someone does) matter more than job titles (what someone is called).
