Increasing complexity of enterprise architectures, encompassing hundreds or even thousands of application systems, has become one of the major challenges in field of enterprise architecture management in the last years. One approach to address this challenge, is the use of a business capability map. A business capability map is a powerful instrument to structure and understand an organization and its required capabilities from the business perspective and serves as basis for a common language between business and IT. These maps allow a graphical representation of business and IT structure and assigned resources such as people, processes, technologies or information on the one hand. But they can also serve as powerful tool to strategically analyze concrete attributes of each capability by visualizing them as a heat map, for example by using color coding, on the other hand. In this paper, the concepts of fourteen business capability based heat maps acquired in cooperation with industry partners, are presented. These cases are based on different indicators representing various aspects of the underlying application landscape. To evaluate the suitability of each case, interviews with expert from 25 companies were conducted. Furthermore, the use of the business capability map in the industry was evaluated to give an overview of the situation today. It turned out, that the business capability map is actively used by a wide range of companies, often in a strategic context. Most of them are still at the very beginning but predict an increasing usage and benefit for the future. Regarding the use cases, it turned out, that it is very important to companies to reveal harmonization potential as well as capability spanning applications.
