The research literature has looked at capabilities of a firm from various dimensions. Through this conceptual note, we aim to classify the literature on eight dimensions: Definition, Portfolio, Utilization, Level, Characterization, Demonstration, Lifecycle, and Development. These eight dimensions cover the various perspectives through which capabilities literature has been approached from and furthered to. This classification is expected to enable researchers in this area to position their studies within or across one or more of these dimensions, thus providing a clear contribution by strengthening or furthering research in the area.
