RT-361

RT-361 upgraded the Project Definition Rating Index–Industrial Projects (also known as PDRI–Industrial) to PDRI MATRS (pronounced “PDRI matters”) by combining two major research efforts:

• RT-113, which introduced the Project Definition Rating Index (PDRI) in 1996
• RT-331, which proposed and demonstrated the value of the combined assessment of the maturity and accuracy of front end engineering design (FEED)
   

By combining the efforts of RT-113 and RT-331, the RT-361 research made significant improvements to the functionality of PDRI:

1. Adding objectivity and consistency to the scoring by giving detailed descriptions and examples for each possible definition level tailored to the 70 PDRI elements
2. Adding a new FEED accuracy dimension to evaluate contextual factors for the environment in which FEP is being conducted
    

RT-361 evaluated its new PDRI framework and tool with additional research that demonstrated increased cost certainty and performance improvement compared to the older PDRI framework. This new dimension is now available in the new PDRI MATRS tool, part of IR113-2, Project Definition Rating Index–Industrial Projects, Version 5.0. PDRI MATRS supersedes both all previous versions of PDRI–Industrial (IR113-2) and FEED MATRS (IR331-2).

PDRI MATRS provides a critical improvement in the FEP body of knowledge. It helps project teams evaluate FEP efforts, including FEED maturity and accuracy, for industrial projects involving new construction or renovation & revamp.
