How can you optimize a large PractiTest project's filter structure for cross-project reporting?

As a project's requirements, tests, and issues grow into the thousands, an unstructured filter tree becomes as hard to navigate as no filters at all, and cross-project reporting only compounds that if different projects organize things inconsistently.

• Standardize a common set of custom fields and filter categories across projects, so a Cross-Project Report can meaningfully group data from each one
• Use Auto Filters for high-cardinality fields, like Component or Owner, instead of manually maintaining a branch per value
• Rely on Cross Filters to keep shared groupings, like Sprint or Release, consistent across Requirements, Tests, and Issues within each project
• Periodically prune or archive stale filters that no longer map to active work, so the tree doesn't accumulate clutter over multiple release cycles

The underlying principle is that Cross-Project Reporting is only as useful as the consistency of the filter and field structure feeding it, a report spanning ten projects with ten different ad hoc field naming conventions won't roll up cleanly.
