How do I write a dashed line?

Write -.- instead of --- for a dashed line without an arrowhead, and -.-> for one with an arrowhead.

The lines cross a lot.

A matrix always has crossings. Drag members in the preview to bring people on the same project closer together.

How do I draw a functional or projectized structure?

For functional, delete the project manager and the dashed lines. For projectized, connect members only to the project manager and delete the functional managers.

Matrix project organizational chart template

Previewed in the “Ink Teal” theme; you can switch themes in the editor

When to use it

Use it in a project management course, in the organization section of a project plan, or when a company introduces project-based work. In a matrix each person has two bosses: a solid line to the functional manager and a dashed line to the project manager, and this chart draws both.

Make it yours

Replace the members with the roles on your project; a function can supply several people.
Strong and weak matrix differ in how much authority the project manager has; say which in a sentence under the chart.
With several projects, add another project manager with dashed lines to that project's members.

Draw a matrix project organizational chart with Mermaid flowchart TB syntax. The general manager is at the top, with the project management office and the engineering, QA, design and marketing managers below. The project manager sits under the project management office. Members sit under their functional managers, connected with solid lines using --- for line reporting. The project manager is also connected to every member with dashed lines using -.- for project reporting. Use no parentheses in node text. Output only the mermaid code block.
