Abstract: exists a multitude of approaches, frameworks, and methods that are used for analysis, design, and planning of strategic capability systems, military capabilities and IS/IT systems. These approaches commonly dictate a single capability definition and practice that should be applied across an organisation or project. This paper examines the practical use and utility of the capability concept with special focus on examining differences between work practices of people with similar job to be done. The examination was done through a case study of a mega-scale programme. It was found that there exist varying common-sense meanings and overlaid practices of the idea capability. When the concept of capability evolved through learning-by-doing, usage of the capability concept was considered as very valuable, this opposed to when a ready-made enterprise architecture framework was introduced. Furthermore, analysis revealed that reported uses were many, varied significantly between work practices, and sometimes incoherent, contradictory and vague. Keywords: Capability, Enterprise Architecture, Performance management, Situational Knowledge, Situational Viewpoint, Air Traffic management.
