Drag to orbit
The honest starting point
Enterprises do not lack diagrams. They lack agreement.
Meridian is built around the model, not the picture. That means the same structure can be reviewed, traced and exported — and it stays true when the next person opens it.
The portfolio is in five places
Capabilities in a spreadsheet, applications in a CMDB, standards in a wiki and the argument in a slide deck. None of them agree.
Review is theatre
A diagram is circulated, comments arrive in three formats, and the decision is made in a meeting nobody can reconstruct later.
Evidence is assembled after the fact
When audit or procurement asks why a system exists, the answer is rebuilt by hand from whoever still remembers.
Governance, without the drag
Controls that look like the work.
Business and Enterprise
Shared libraries
A single capability, application and data library that every map draws from. Change it once, see it everywhere.
Roles and review
Editors propose, reviewers comment, admins publish. The state of every model is visible without a meeting.
SSO and provisioning
SAML and OIDC on Business and Enterprise, with SCIM provisioning and group-based access.
Audit and traceability
Every node, edit and export is attributable. Trace a brief back to the model it came from.
Evidence packs
Export the map, the PlantUML source, the brief and the revision history as one decision record.
Retention controls
Set how long workspaces, comments and exports are kept. Regional tenancy available on Enterprise.
Merge requests for models
Propose a change without editing the published version.
Reviewer sign-off
A named reviewer accepts or returns the model with comments attached.
Decision record
The map, model, brief and history exported as one evidence pack.
