Architecture Framework

Enterprise architecture is at a point in the hype cycle where there is perception that it has not lived up to its promise. In this talk, we cover the history of the DoD Architecture Framework, current challenges facing the architect, and the forces that drive enterprises to design and deliver where there is no time for a strategic pause to architect. The author discusses important concepts that are addressed in the DoDAF that must be paid attention to regardless of the direction where the DoDAF evolution is headed. This talk was presented at the Association of Enterprise Architects, San Diego CA on February 24, 2017.

This paper presents a conceptual framework for understanding architectural works. This framework provides an understanding of an architectural building through qualitatively discerning the complexity of issues involved in its design and enabling their systematic integration into a theoretical construct. The premise behind this framework is that in design a better understanding of ‘what’ to design leads to a more informed base to ‘how’ to design, consequently resulting in a more structured and innovative architectural design. Using a grounded theory method, the paper postulates an ontological framework that recasts the Vitruvian triad of utilitas, venustas, and firmitas into spatial form, intellectual form, and structural form respectively, and more importantly expands the triad to include context, and architectural thinking manifested as formative concept, as an integral component in any architectural work, thus closing a gap that existed in many frameworks dealing with architecture. The paper concluded that this framework offers a level of robust understanding of architecture that can become a foundation for a more effective and rational architectural design practice. This foundation can be used as a base in structuring the generation of architectural form as well as the description and analysis of existing works of architecture. Its value exceeds theory framing and extends towards architectural pedagogy as a theoretical framework in teaching design studio.

Remote-controlled or autonomous multi-rotor air vehicles, or drones, have become common and commercially available even to individual consumers, mostly for imaging purposes. Drones appeal to mission architects looking to extend the toolbox provided to operators performing challenging missions such as public safety operations. However, careful analysis of the operational context and concept of operations must take place before major acquisitions. The purpose of this paper is to propose a model-based operational architecture definition framework, which is based on the Department of Defense Architecture Framework (DoDAF) ontology and uses Object Process Methodology (OPM) as its underlying modeling language. Through careful mapping of DoDAF Operational Viewpoint (OV) ontology to OPM ontology, we were able to show that the entire OV ontology can be covered by a small set of objects, processes , relations among them, and constructs comprising them. We then show how to instantiate the ontology to create a model of an actual architecture of interest (AoI) while maintaining strong typing of the model elements to ensure validity, integrity, consistency, and continuous compliance with the OV. We demonstrate our approach on the case of using drones in public safety enterprises for the purpose of crowd management in massively attended events and locations. The proposed framework allows for capturing ConOps and OpsCon in a lightweight, yet robust and consistent manner, and improve communication and concept validation between operational stakeholders and enterprise architects.

A central aspect of architecting is architecture description. Architecture descriptions take many forms and serve many purposes throughout the life cycle of development, operation and maintenance activities. The use of multiple views--diverse representations for distinct audiences and uses--has been a major tenet of architecture description since the earliest work in software architecture. This tenet has been codified in various ways. Most practising software architects must operate within the confines of a prescribed architecture ...

Spatiotemporal data mining is an emerging area of research. Applications for mining different kinds of spatiotemporal patterns and trends are being developed by researchers in various domains. However, there is a need for underlying architecture framework for these applications to provide reusability of analysis and design. This research paper addresses such a requirement by adopting conceptual model of architecture framework described in ISO/IEC 42010:201X standard for Systems and Software Engineering-Architecture Description. This research identifies stakeholders and their concerns, describes context, integration, information, functional, concurrency and technology viewpoints as architectural viewpoints which provide reusability of analysis and design for spatiotemporal data mining applications. The correspondence rules which describe correspondence among the viewpoints are also described.

This paper presents a case study on the experience of a technical architecture team, the AAV Team, while developing an architectural design description (ADD) for an IT system focused on the application viewpoint of the technical architecture. The project charter and requirements for the assignments of the AAVT Team project are based on a real-world initiative in a global automotive manufacturing company to upgrade its existing Global Purchasing System and deploy a new Global Contract Module. The purpose of the upgrade is to provide all purchasing system users with the required minimum hardware and software prior to implementing the new release of the Global Purchasing System with the ultimate goal to ensure that current users have successful access to the new Global Contract feature and related information. The team assignments performed by the AAV Team formed part of the requirements of a course on IT Systems Architecture in a Doctorate of Management in Information Technology. The ...

Abstract This paper presents a state-of-the-art overview of distinguishable approaches, overview of some writings that have themes and a similar discussion, with the background to provide an overview to the readers of control and things related to multimedia information security, all attempting to define multimedia information security architecture, followed by a proposition of requirements for multimedia integrated security architecture. There is no standardized and comprehensive of multimedia information security architecture currently ...

With commercial and military systems becoming more complex, using more sophisticated products, complex processes, and specialized people and having longer system life cycles, it is essential that organizations have a systematic approach to managing systems from an Obsolescence Management System perspective. This paper presents a new systems engineering architecture framework, House of Systems Engineering HoSE, and shows how its constructs can be applied to support the building of a proactive Obsolescence Management System framework. We first provide a brief overview of the HoSE, including the systems engineering aspects and the systems architecture methodology used in the HoSE. Next, we discuss the 2-dimensional Obsolescence Management System framework based on the HoSE. Finally, a case study is performed to justify the framework. The case study results suggest that the framework is beneficial in finding gaps in an Obsolescence Management Plan. © 2013 Wiley Periodicals, Inc. Syst Eng 17
