The construction industry has for a long time had lower productivity growth than other industries. In addition, many construction projects are characterised by technical systems that don't function as expected in the project's final phase, or once the building is put into operation.
Per Roger Johansen and Tor I. Hoel previously co-authored BA2015's guide to Systematic Completion, created to improve productivity in the industry and ensure the finished product actually works correctly, in line with what the customer ordered. In the years since that guide was published in 2015, Systematic Completion has received considerable attention, but the industry has invested relatively little in building expertise around it. Few project owners and project managers have fully grasped what Systematic Completion actually means for project delivery, and what it delivers in the final phases.
Now the same authors, together with Project Norway, have introduced a new standard: FMI: Function Maturity Index. The goal of the standard is to establish a common way to communicate, within a project, how far each individual technical system has come in its development.
The seven main levels
FMI gives each technical system a maturity value along a scale from early planning to operation:
- FMI100Plan for Systematic Completion established
- FMI200Functional description per system completed
- FMI300Table test accepted
- FMI400System functional test accepted
- FMI500Integrated tests / full-scale tests accepted
- FMI600Operational tests accepted
- FMI700Normal operation
Each project is free to establish intermediate levels to follow development even more closely, and FMI is designed to harmonise with the already established Model Maturity Index (MMI) for BIM, so the two can be used side by side.
Frequently asked questions
What is FMI?
FMI, the Function Maturity Index, is a standard for communicating where each technical system is in its development. The scale runs from FMI100, commissioning plan established, to FMI700, operation.
Who developed FMI?
The FMI guideline was written by Per Roger Johansen and Tor I. Hoel, with contributions from Hans Thomas Holm and Per-Ivar Mikkelsen, in collaboration with Prosjekt Norge at NTNU.
How does FMI relate to MMI?
FMI is designed to align with the Model Maturity Index (MMI) for BIM, so the two can be used side by side.
Can a project add its own levels?
Yes. Each project is free to define intermediate levels to track progress more closely.
