Cp and CpK are process capability indices used to measure and analyze process capability. These are metrics related to continuous characteristics. The Cp value indicates the ratio of the tolerance width to the process spread (process range) or the potential process capability assuming exact centering within the tolerance window. It is calculated by dividing the difference between the upper and lower tolerance limits by the process range. The Cpk value focuses on precision and accuracy. It is the result of dividing the distance between the process mean and the nearest tolerance limit by half the width of the process range.

The 5S workplace organization is an important method of Lean Management. It is a systematic approach to maintaining an efficient, safe and clean workspace.5S was developed by Toyota in Japan. The tool can be applied in all areas of production and services.

Kanban is a method from Lean Managementused to control material flow. Cards regulate the material. Kanban (Japanese: Kan = signal, Ban = card).

A procedure instruction is a document from quality management that lists the individual activities or processes that make up a procedure in an orderly sequence. Procedure instructions are required by standards. The scope and depth of documentation, as well as the format (paper or electronic), depend on the size and structure of the organization. Procedure instructions are, like the QM manual, an important element of QM documentation.They clearly present all the sub-activities necessary for carrying out a procedure. They detail who is responsible for the tasks or what skills are required, but exclude details such as key figures. Additionally, they are designed for cross-departmental and cross-location application. In contrast, work instructions provide all the necessary information for executing a single task, such as timing, location, and procedure. Therefore, these documents should be differentiated from one another. Possible contents of procedure instructions may include descriptions such as purpose, scope, responsibilities, definitions, procedures, and related documents.

TIMWOOD is an acronym representing seven types of waste that can occur in a process. These wastes are non-value-added and must be reduced.

Further Explanation:

T – Transport costs time and money and can cause damage.

I – Inventory ties up capital, requires space, must be transported, and monitored.

M – Unnecessary movement by employees wastes work time.

W – Often machines wait rather than people.

O – Excess work for something not currently needed.

O – Overproduction ties up capital and resources.

D – Errors and rework consume capacity.

Value Stream Mapping (VSM) is a Six Sigma method used to align the process with customer demand (takt time). Optimization potentials are derived from the VSM.

All process steps required to produce the final product from raw materials are recorded. The material flow is considered backward, from the customer to the supplier. Through simple visualization, you can quickly see the most important aspects of your manufacturing process. The value stream design is developed from the value stream analysis as a vision.

Voice of Customer (VOC) is a tool used to translate verbal statements from external customers into measurable core statements. This involves directly surveying the customer and/or the sales team if direct customer feedback is not feasible. A Voice of (external) Customer may or may not always be present.

If the outcome of a product or service from a process is not satisfactory, the process must be optimized or the product must be redeveloped. A DMADV project has the highest project potential compared to DMAIC projects in Lean Six Sigma. This means that for your next development, you should use the DMADV tools.

Value Add Time (VAT) refers to the portion of the cycle time for which the customer is willing to pay. Maximizing this time makes you more efficient.
