How to Build an Effective Multi-Vendor Coordination Framework for Industrial Projects

This prevents the common situation where two vendors each assume that the other is responsible for an interface.

A package boundary should be specific enough to answer a simple question: Who owns the work between these two systems?

2. Create an Interface Register

The interface register should become the central working document for coordination.

Instead of recording only vendor names, record every significant interaction between packages.

The register should also capture technical queries, affected drawings, required decisions and closure evidence.

This approach changes coordination from a reactive activity into a measurable process. Research published by PMI on engineering interfaces similarly identifies clear interface definition, information exchange and timely resolution of interface issues as important controls against rework and schedule disruption.

3. Establish a RACI Responsibility Matrix

Every important activity should have a defined responsibility structure.

A RACI matrix can identify who is:

• Responsible for performing the work
• Accountable for the outcome
• Consulted before decisions are made
• Informed about progress or changes
