Which Lean principle states that overly complicated processes add more cost than benefits?

• A. Law of focus
• B. Law of flexibility
• C. Law of complexity
• D. Law of velocity

Answer: (C)

The principle that states that overly complicated processes add more cost than benefits is the Law of Complexity. This principle emphasizes that as processes become more complicated, they not only increase the chances of errors and defects but also lead to higher operational costs. Complex processes can obscure clarity, making it difficult for employees to understand their roles, thereby wasting time and resources. Simplifying processes, on the other hand, enhances efficiency, reduces waste, and ultimately delivers greater value to both the organization and its customers.

The emphasis of this principle aligns with Lean thinking, which advocates for eliminating unnecessary steps and simplifying workflows to streamline operations. By focusing on simplicity, organizations can achieve better performance and reduce costs associated with complexity, such as training, process variations, and management oversight.
