Big data analytics capability (BDAC) is a firm's ability to leverage big data for business value generation. Firms focus either on ‘functional fitness’ by ‘doing the things right’, or ‘evolutionary fitness’ by ‘doing the right things. Extant literature shows inconsistency in BDAC dimensions and lacks an integrative framework that addresses both functional and evolutionary fitness. We address this through a tool-based qualitative analysis of BDAC literature and present a capability-centric fitness framework. In doing so, we examine the critical role of enterprise architecture and suggest TOGAF based mechanisms to address alignment issues between BDAC’s functional and evolutionary fitness dimensions.
