In Article 15, our discussion concluded with an exploration of the key steps in "Define Performance Standards." In the upcoming articles, including this one and the following ones, we will delve deeper into the concept of Operational Definition within the framework of Define Performance Standards. Through these discussions, we aim to provide a more thorough understanding of the Operational Definition and its significance in establishing precise and effective performance standards.
The Key Steps in “Define Performance Standards” are:
· Develop the Operational Definition
· Define Unit
· Define Opportunity
· Identify the Target
· Identify Specification Limits
· Define a Defect / Defective
· DPU /DPMO
An Operational Definition is a precise and explicit description that serves to clarify both what the Critical to Quality (CTQ) is and the methodology for measuring it. It functions as a comprehensive guide, providing a clear understanding of the essential quality parameter and describing the specific steps or criteria for its measurement. By encapsulating the essence of the CTQ and outlining the measurement process, an operational definition becomes a valuable tool in ensuring a standardized and unambiguous interpretation of critical quality aspects within a given context. We need to have Operational Definition in order to:
· Remove ambiguity in understanding between team members
· Clearly defines a “standard” way to measure a CTQ
· Ensuring that CTQ representation is correct and independent of different times and operators
Below is an illustration of targets and specification limits of two processes based on customer specification limits:
Now that we've grasped the importance of Operational Definitions, stay tuned for Article number 17, where we'll dive into their practical application. We'll explore essential elements like Unit, Opportunity, Target, Specification Limits, Defect/Defective, and DPU/DPMO, providing insights into their role in implementing Operational Definitions effectively. Join us for a concise yet comprehensive examination of their practical implications in our ongoing discussion on performance standards.
