# Custom fields

Use custom fields to add properties that provide helpful insights for scheduling, planning, and reporting.

You can use custom fields for people or projects.

- People: Add properties, including skills, certifications, managers, and organization structure.

- Projects: Add business-specific criteria to specify properties such as Portfolio Editor, project priority, the likelihood of closing, business unit, project IDs, and location.

You can add multiple custom fields to projects and people and use them as filters on the schedule page, project portfolio page, or reports.
