Abstract
This study aims to differentiate firm-level capabilities in terms of managerial-level competencies of a Sri Lankan telecommunication service provider. A framework is developed and survey data are used to identify a range of factors at managerial competency level that form firm-level capabilities as a result. Multiple regression is used to identify how much variance in the latter is predicted by the former. It is expected that the methodology adopted in identifying and integrating managerial-level competencies and firm-level capabilities provides an innovative integrated methodology of significant value for practitioners and academics alike. Managerial implications, limitations and directions for future research are discussed.
