Assurance, not audit

Surface schedule quality signals with clear concern levels — so reviewers spend time on what matters, not hunting through raw data.

Review priorities, not data dumps

High and moderate concern items are surfaced first. Detailed evidence is one click away when you need to go deeper.

Built for PMOs and project managers

Plain-language findings. Designed for the people who need to act on schedule quality, not just analyse it.
