View Full Bio

Mr. Humphreys’ past experience demonstrates his depth of knowledge and passion for earned value management. He was the first U.S. Army Team Director to conduct an EVMS Tri-Service Demonstration and led numerous EVMS Validation Reviews. As both a Team Member and Team Director, Mr. Humphreys has assisted, evaluated, and directed review teams leading to successful system acceptances.

He was elected to the Nine Man Committee for increasing the cost effectiveness of earned value and led the Fifteen Man Industry Committee to modify traditional documentation and interpretation of earned value to be more compatible with efficient, economical production management control techniques. As a member of the Integrated Program Management Initiative Joint Team, Mr. Humphreys received DoD's highest acquisition award, the 1998 David Packard Excellence in Acquisition Award. He is also a recipient of the Whitey H. Driessnack Award for Outstanding Contributions to the Advancement of Performance Management.

He has served as Vice-Chair and Chair of what is now the National Defense Industrial Association (NDIA) Program Management Systems Subcommittee (PMSC). It was through the NDIA PMSC that he orchestrated the first ever survey on EVMS. As a direct result of this survey's findings, the US Government conducted their own survey. These two independent surveys formed the genesis for subsequent revisions to numerous guides and reference material on EVMS. He served as leader of the Total Quality Management (TQM) Process Action Team (PAT) for streamlining business system descriptions for performance measurement and management applications. He was also part of the eight person team that developed the ANSI/EIA-748 Standard for Earned Value Management Systems.

Under his leadership, the Performance Management Association (PMA) (now the College of Performance Management) achieved importance as a policy influencing group. He initiated international Chapters in Australia as well as new US Chapters.

He authored the first and second editions of Project Management Using Earned Value published in 2002 and 2011. He was a co-author of Project and Production Scheduling, published in 1987. He has also written numerous articles on subjects related to project management and earned value.

Mr. Humphreys holds a Bachelor of Science from the University of California at Berkeley and a Masters in Business Administration from the University of Southern California.
