- Exploring the classification structure — Understanding how divisions break down into groups, groups into sections, and sections into more specific classifications.
- Discovering related sections — Browsing adjacent sections to ensure you have captured the full scope of work for a specification or bid package.
- Learning the standards — New team members can use it to understand how MasterFormat is organized.
