CDE — common data environment

Short answer
Common Data Environment: a single agreed-upon place for storing and sharing project documentation, with control over versions, statuses, and permissions. Not the same thing as a shared drive.

A CDE is often confused with a folder in the cloud. The difference is single but fundamental: in a CDE, every document has a status and a version, not just a file name. As long as the binding version is recognized by a suffix in the file name ("_final_v3_ost"), the environment is not common — it is merely commonly accessible.

The minimum feature set

Step 1.Status
Draft / under review / approved / archived.
Step 2.Version
Assigned by the system, not by whoever names the file.
Step 3.Permissions
Who can view, who can comment, who approves.
Step 4.Audit trail
Who changed what, and when — reconstructible years later.

When a CDE does not solve the problem

A CDE brings order to documents. It does not bring order to operational data — quantities, acceptance statuses, assignment to work fronts. Deploying a CDE where the real problem is a missing register of quantities and statuses ends with a tidy archive sitting next to a still-unknown state of the works.
