Following Dunlap et al. (2003), the practical cut-off value for a Likert-type response scale with five options is 0.83 or less. Therefore, examination of ADIs was found to be satisfactory for factors studied in both the OLC and KM scales. These results assure a reasonable intra-organizational agreement and heterogeneity between organizations, leading us to the aggregation of individual answers into an organizational score (mean of the organization) separately for all the studied dimensions (internal integration, external adaptation, KM formal practices, KM informal practices, and strategic management of knowledge) in all the firms of the sample.
The two predictor variables were, therefore, entered in blocks in the three regression equations: first they were entered with the criterion variable KM formal practices, then with the criterion variable KM informal practices, and finally with the criterion variable strategic management of knowledge.
