Continuous Improvement
Teams regularly reflect on performance, learn from both successes and failures, and make adjustments to improve the system. Improvement is ongoing and embedded in everyday project work.
Focus on Flow
Work is planned and managed so that activities move smoothly from one team to the next without interruption. Reliable workflow improves productivity, reduces delays, and stabilises project delivery. Details: Focus on Flow | Lean Construction Institute
Remove Waste
Teams identify and eliminate activities that do not create value, such as waiting, rework, overproduction, and unnecessary handoffs. Reducing waste frees up time and resources for productive work.
Generate Value
Projects focus on delivering what truly matters to owners, users, and communities. Teams work to understand stakeholder needs and ensure the project delivers meaningful outcomes, not just completed tasks.
Respect People
Lean construction recognises that the knowledge and experience of the people doing the work are critical to project success. Teams collaborate openly, support one another, and create environments where everyone can contribute to improving outcomes.
Optimise the whole
A Lean principle: make decisions to improve overall project outcomes (cost, schedule, value, quality) rather than maximising performance of one discipline, package, or organisation.See also: Shared risk / shared reward, Business case, Cost to complete forecasting
