The Three Main Chart Types
Before you can read an org chart, you need to know which type you are looking at. The same company might produce two very different charts depending on which structure it is trying to show.
Hierarchical (Top-Down)
The classic pyramid. CEO at the top, direct reports below, and so on down to individual contributors. Each person has exactly one manager. Lines are solid. This is the default for most companies and the easiest chart to read — just follow the lines upward to find the chain of command.
Matrix
Employees have two managers: a functional manager (their department head) and a project or product manager. Matrix charts use dotted lines to show the secondary relationship. Common in consulting firms, agencies, and large tech companies. Harder to read, but more honest about how cross-functional work actually happens.
Flat
Very few layers between the CEO and individual contributors. Common in early-stage startups and deliberately non-hierarchical companies. When you see a flat chart with a wide first tier directly under the founder, it usually means the company has not yet formalised management — not that everyone genuinely has equal authority.
What Solid vs Dotted Lines Mean
Lines are the grammar of org charts. Getting this wrong leads to real confusion about who actually manages whom.
Solid line
Direct reporting relationship. The manager below the line is responsible for this person's performance reviews, compensation decisions, and day-to-day oversight. If someone asks “who is your manager?”, the answer follows the solid line.
Dotted line
Secondary or influence relationship. This manager has some authority over the person's work — often project delivery, functional standards, or strategic direction — but does not own their career development or compensation. Common for shared services, legal, finance, and compliance roles embedded in business units.
A dotted line is not a weak relationship. In some matrix organisations, the dotted-line manager has more day-to-day influence than the formal manager. Context matters: a finance business partner with a dotted line to the CFO may functionally answer to the CFO on all substantive matters.
How to Read Department Groupings
Most org charts colour-code or visually group people by department or function. When you see a cluster of boxes in the same colour or enclosed in a boundary, that represents a team or department that shares a reporting line, a budget owner, or a functional identity.
Reading groupings tells you several things at once:
- Budget ownershipEach department cluster typically has a single budget holder at its apex — the person all costs roll up to.
- Functional alignmentPeople in the same cluster usually share tools, processes, and professional development paths, even if they work on different projects.
- Political territoryIn resource allocation decisions, departments compete. Seeing where the boundaries are drawn tells you where resource tension is likely to exist.
- Headcount signalsA large cluster relative to others signals company priorities. A 40-person engineering department vs a 5-person sales team tells you something about the growth model.
Span of Control and What It Signals
Span of control is the number of direct reports a manager has. It is one of the most diagnostic signals in an org chart — not just a number.
2–3 reports
Narrow span
High specialisation, close supervision, or the manager is still in growth mode. Common in early exec hires where one person owns a new function.
4–7 reports
Standard span
The most common configuration for middle management. Allows meaningful 1:1 time while keeping teams small enough to coordinate effectively.
8–15 reports
Wide span
Signals a flat, delegating management style or a function where work is highly independent. Common in engineering, customer support, and mature sales teams.
When span of control is inconsistent across an org chart — one manager with 12 reports next to another with 2 — it often signals an organisation in transition: recent reorgs, departures, or roles that have not yet been properly staffed. Spotting these anomalies is one of the most useful things a recruiter or consultant can do when reviewing a client's chart.
Common Misconceptions About Org Charts
Org charts are formal documents. They represent the intended structure, not the lived reality. Here is what they routinely get wrong — or deliberately omit.
Myth: “The org chart shows who has power”
Reality: Formal authority and informal influence are different things. The most politically powerful person in a company often has a title two levels down from where you would expect. Org charts show reporting lines, not influence maps.
Myth: “A flat chart means a non-hierarchical culture”
Reality: Many "flat" companies have strong informal pecking orders. A founder with ten direct reports and no C-suite is still running a hierarchy — it is just implicit rather than documented.
Myth: “Titles indicate seniority consistently”
Reality: A "Director" at a 20-person startup has almost nothing in common with a "Director" at a FTSE 100. Org charts without headcount, scope, or budget context can be deeply misleading across company sizes.
Myth: “The org chart is current”
Reality: Most org charts are out of date by the time they are shared. People leave, teams restructure, and interim arrangements become permanent. Always ask when the chart was last updated — and expect the honest answer to be "longer ago than it should have been."
Frequently Asked Questions
What does a dotted line mean on an org chart?
A dotted line represents a secondary or indirect reporting relationship — sometimes called a "dotted-line authority". The person does not directly report to that manager day-to-day, but that manager has some influence, oversight, or shared accountability over their work. It is common in matrix organisations where an employee has both a functional manager and a project or business unit manager.
What does an org chart show?
An org chart shows the formal reporting structure of an organisation: who reports to whom, how teams are grouped, and how authority flows from top to bottom. It does not show informal influence, communication patterns, or actual decision-making power — those require a network analysis or influence map, which is a different tool.
What is span of control in an org chart?
Span of control refers to the number of direct reports a manager has. A wide span (8–12 reports) signals a flat, autonomous culture where managers delegate heavily. A narrow span (2–4 reports) suggests close supervision, specialised work, or a team that is still being built. Reading span of control across a chart tells you a lot about how the organisation actually operates — not just how it is named.
How is a matrix org chart different from a hierarchical one?
A hierarchical org chart has a single chain of command — each person reports to exactly one manager. A matrix org chart reflects dual reporting lines: employees have both a functional manager (their department head) and a project or product manager. Matrix structures are common in consulting firms, tech companies, and large multinationals where cross-functional teams need to work across departments without changing the formal hierarchy.
