Lean engineering principles are a set of practices that are designed to reduce waste and optimize efficiency in the engineering process. The main focus of lean engineering is to reduce the amount of time and resources needed to produce a product or service. This is achieved by eliminating non-value-added activities, streamlining processes, and improving communication between stakeholders. Lean engineering also emphasizes the use of data-driven decision making to ensure that decisions are based on facts rather than assumptions. The ultimate goal of lean engineering is to reduce costs and improve customer satisfaction. By using lean engineering principles, businesses can reduce costs, increase efficiency, and improve customer satisfaction. This can lead to improved profitability and competitive advantage. Lean engineering is an important part of any business strategy and should be incorporated into the overall business plan.
