Hal is a Principal Lean Project Consulting, Inc. He has his attention on project leadership and organization transformation in a lean environment with special attention to Integrated Project Delivery (IPD). In the last few years, Hal and the team of project coaches have advised and coached more than two dozen IPD projects.

Project management, one of the most-cited career positions, routinely fails to produce the desired business results. Projects are routinely over budget, late, and fail in often significant ways to satisfy the customer and the project participants. Worse, in the built environment many people are seriously injured along the way. The bulk of today’s efforts at improving projects are spent on doing a better job applying the same old techniques. In conjunction with the Lean Construction Institute, Hal has set out to change that.

Hal’s career spans numerous industries and roles including industrial engineering, factory production control, worldwide quality management, software development, management of design-build construction and consultants on the Last Planner® System and integrated Lean project delivery. He is now giving significant attention to sound decisionmaking teaching and facilitating with the Choosing By Advantages Decisionmaking System.

Hal studied economics and operations research and operations management. His career-long preoccupation with operations effectiveness has led to numerous innovations including Study-Action TeamsTM, distinguishing Target-Value Design, creating Responsibility-based Project DeliveryTM and the Good 5-WhyTM approach for root-cause analysis. Hal introduced “making and securing reliable promises” as the foundational competence for performing well when using the Last Planner® System.
Hal is a fellow of the Lean Systems Society.
