12/28/2022 0 Comments Operational research definition![]() Any time data is being collected, it is necessary to define how to collect the data. An Operational Definitions Worksheet (ODW) should, therefore, be made in the measure phase before the collection of data begins. When collecting data, it is essential that everyone in the system has the same understanding and collects data in the same way. Measure Phase: Operational Definitions Worksheet ![]() Therefore, operational definitions should be developed and tested before the data collection begins in the measure phase. It is particularly important when a decision is being made about whether something is defective or not, whether a defect exists or not etc.įor example, how do you know if a package via courier has been delivered on time or not on time? The data collection will be meaningless if the definition of ‘On Time’ has not been specified. You need operational definitions when collecting all types of data in the measure phase. This helps ensure reliability, also the consistency is built in up-front during the measure phase. The purpose of the definition is to provide a single, agreed upon meaning for each specific “Y”. Operational Definitions of the measure phase are used to baseline the performance. It must be communicable, with the same meaning to vendor as to purchaser, same meaning yesterday and today…” Why set a baseline? “An operational definition is one that people can do business with…. Operational definitions of the measure phase can also include text descriptions, pictures, photographs, models or samples. ![]() It is often used for attribute data and describes a standard criterion to measure against. In Six Sigma Measure Phase, an operational definition is a precise definition of the specific “Y” to be measured. It is a concept to guide what properties will be measured and how they will be measured during the measure phase.Īttend our 100% Online & Self-Paced Free Six Sigma Training.ĭefining Operational Definition of the Measure Phase An operational definition is a clear, concise and detailed definition of a measure, that’s why it’s an important term for the measure phase. It is a protocol that is followed in the MEASURE phase of the DMAIC process as discussed in Lean training courses. Let’s define an “Operational Definition.” It can be defined as a clear and understandable description of what is to be observed and measured, such that different people collecting, using and interpreting data will do so consistently. Six Sigma Green Belt practitioners who took a Lean Six Sigma Green Belt training have a firm grasp on the concept of “Operational Definition” in the measure phase and how it can help a project using the Six Sigma approach.
