P2SL Benchmarks
The University of California Berkeley’s Project Production Systems Laboratory (P2SL) has been developing benchmarks so we can gauge the “current state” of implementation of lean practices in industry, indicate opportunities for improvement of that current state, and provoke ideas on how to improve the benchmarks themselves.
We periodically publish a description of the current benchmark in each project management process that is a subject of P2SL research. Current process benchmarks are developed with industry practitioners to best incorporate the latest advances in both theory and practice. Consistent with the Lean philosophy of continuous improvement, each publication of a process benchmark includes a description of the research needed to surpass it.
