Engineering projects, whether in construction, manufacturing, software development, or infrastructure, are often complex and resource-intensive. Traditional project execution methodologies can lead to inefficiencies, delays, and cost overruns. Lean principles, originating from the Toyota Production System, have revolutionized manufacturing and are increasingly applied to engineering projects to improve efficiency, reduce waste, and enhance value for stakeholders. This article explores how Lean principles can be effectively implemented in engineering projects, ensuring streamlined processes, optimized resource utilization, and increased project success rates.
