-Functional decomposition is the primary component of enterprise activities description and is often associated with business process architecture. It guides any business improvement initiative, enables to design the enterprise construction -organizational structure, IT-and HR-architectures, etc, as well as to deploy goals and strategies. The paper suggests the framework for enterprise functional decomposition, which includes the ontology for enterprise activities description, foundations and the process of functional decomposition. The suggested framework integrates the following features: alignment with goals decomposition; support for reference models and other reusable activities descriptions; recursive decomposition using a single activities pattern; value-based management and ISO 9004:2009 harmonization. The paper also describes framework implementation at Russian enterprises and IT tool to support the approach.

Nowadays enterprise architecting and business process engineering are almost synonymous to diagramming. Diagrams have many benefits and are sufficient for many situations. But as the number of diagrams and their types grows, they overlap and evolve, then it becomes hard to maintain a collection of interrelated diagrams, even with the help of a common repository. Besides the very nature of enterprise architecting requires a lot of matrices (goalsprocesses, capabilities-processes, processes -applications…). The paper presents the multi-representation approach for enterprise architecture model development and maintenance. Classifications and matrices are the basis of this approach and support knowledge structuring and integration. The ORGMaster tool joins classifications and matrices with traditional diagram-based technologies. The paper pays special attention to the role of classifications and matrices in integrating business processes into enterprise architecture

Th e paper aims to develop a method for strategic alignment of the organization's activities based on the technology of the Quality Function Deployment. Th is method contributes to alignment of the objectives and metrics of current activities (business processes, functional systems) and development activities of the company (projects and development programs) with the objectives and strategy of the company. It also ensures the prioritization of activities and identifi es the relationships between organizational capabilities and objectives. Th e paper presents formalization of the Quality Function Deployment technology by building a method-specifi c ontology. Th e method can be used for managing enterprise transformation along with the other enterprise architecture management methods and technologies based on organizational modeling due to a high degree of its formalization achieved by building an ontology. Th is is especially important in the digital economy era, when the object of enterprise transformation is not only organization of work, but also information systems of companies. Th e proposed method has an advantage in that it ensures a high level of adaptability to the management problem being solved and the terminology being used within the organization. It enables carrying out a strategic alignment both for the business area as a whole and for the functional system (domain) separately. Moreover, despite a high degree of formalization, the underlying Quality Function Deployment table-graphic technology provides opportunities for visualization, which makes the considered method of strategic alignment of the organization's activities readily available for understanding and use among practicing managers. Implementation of the method under consideration is shown in the context of developing an operating strategy for a medical company.
