Operations research is the application of the methods of science to. You need an operational definition because you cant measure anything without one, no matter how good your conceptual definition might be. Operations Research has been defined so far in various ways and still not been. (2010).The nursing contribution to qualitative research in palliative care 1990-1999: A critical evaluation. Your operational definitions describe the variables you will use as indicators and the procedures you will use to observe or measure them.

However, as many qualitative approaches to method show, one may have the purpose of clarifying and specifying without necessarily making the unmeasured quantitatively measureable. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical analysis. USING OPERATIONAL DEFINITIONS IN RESEARCH 123 i.e., that clear, scientific specification and measureable operations are one and the same. Referenceīailey, C., Field D., Froggatt, K., & Krishnasamy, M. Operations research (OR) is an analytical method of problem-solving and decision-making that is useful in the management of organizations. The two methods of definition thus cannot complement each other in research work. These numbers will provide the raw material for our statistical analysis. A simple and accurate definition of measurement is the assignment of numbers to a variable in which we are interested. The operational definition aims at specifying the exact events or activities that the researcher used in measuring the conceptual definitions that further increase the understanding of the reader of the research. Operational Definitions An essential component of an operational definition is measurement. On the other hand, the use of operational definition in a research paper to define the variables would help the reader in understanding the operations or steps used by the researcher in measuring the concepts. The definition thus helps the reader in the interpolation of the variables. The use of working or conceptual definition also helps in increasing the reliability of the research findings as different concepts may cross-serve each other. Also, the conceptual definition is mainly essential in research work as it helps the reader to understand the meaning of the researcher especially on the terms or concepts that may have different meanings or that may be conflicting (Bailey, Field, Froggatt & Krishnasamy, 2010).

This helps the reader to have a clear understanding as he or she goes through the research. The working definition gives the reader the meaning of the terms and concepts used by the researcher. In the research, variables should be defined using both ways.
