Operationalization means making theoretical constructs measurable. Before evidence can be collected and the relationships of the effects can be examined, it must be determined how to measure the constructs used, i.e., how they are to be converted into numbers or, at any rate, into evaluable nominal categories. Thus, a catalog must be developed of the criteria and sub-criteria that are constitutive for the theoretical construct of Complementary Management and leadership. Following on from this, measurement instruments for the individual sub-criteria need to be developed. A special research team has been working on these questions for some time.
