1. Market rules

The first law, also known as the first law, is the basis for formulating other laws. Therefore, this law is an indispensable part in the process of lean six sigma. According to this law, "customers are vital to quality" is the definition of quality, which constitutes the main focus of improvement. Followed by the return on investment capital and net present value (NPV).

2. The law of flexibility

The law of flexibility points out that any speed of a process depends on its elasticity or flexibility. This means that in the process of adapting to changes, the higher the acceptance and flexibility, the better the project implementation.

3. The law of focus

The third law of lean six sigma points out that 80% delay in any process is caused by 20% process activities. This is based on Pareto principle. This law is usually interpreted as being able to identify the main reasons for the delay of such activities and allowing a quicker refocus on the targeted phase of implementation.

4. Law of speed

This law gives a clearer definition of the speed of the process. This law shows that the speed of the process is inversely proportional to the work done. This method focuses on completing the process as soon as possible to ensure timely delivery. This law reveals how the speed of ongoing work affects the speed of project implementation.

5. Law of Complexity

This law explains how when a complex becomes too complex, it brings a lot of non-value-added costs to the ongoing work. Complexity has a greater impact than slow speed, poor quality and low sigma. In short: the more complex the task, the higher the cost, and the greater the workload required to complete the task.
