Systems Engineering/Systems Engineering and Technical Assistance (SETA)
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles. At its core systems engineering utilizes systems thinking principles to organize this body of knowledge. Issues such as requirements engineering, reliability, logistics, coordination of different teams, testing and evaluation, maintainability and many other disciplines necessary for successful system development, design, implementation, and ultimate decommission become more difficult when dealing with large or complex projects. Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. It overlaps technical and human-centered disciplines such as industrial engineering, mechanical engineering, manufacturing engineering, control engineering, software engineering, electrical engineering, cybernetics, organizational studies and project management. Systems engineering ensures that all likely aspects of a project or system are considered, and integrated into a whole.
SETA is an industry term, which the U.S. Department of Defense (DoD) has used since at least 1995, for example in the Software Engineering Institute (SEI); ‘Defense Acquisition Deskbook, “S”; the An Acronym List for the Information Age (Armed Forces Communications and Electronics Association); the DoD Guide to Integrated Product and Process Development). The government often needs to supplement its internal SETA capability in order to meet its frequently changing needs and demands. Through a formal Request for Information (RFI)/ Request for Proposal (RFP) process the government is able to contract with a commercial organization to provide certain services. SETA contractors work alongside government employees often within the same workspace. SETA contractors may participate in government contracting actions and may assist in managing other contracts. A SETA contractor cannot be the Contracting Officer Representative (COR) or Assistant COR (ACOR), but they may function as the Technical Point of Contact (TPOC). Since SETA contractors may have access to procurement sensitive information there is a risk of Conflict of Interest (CoI) which is mitigated through Non-Disclosure Agreements (NDAs) and firewalls restricting communications within corporations.
Enterprise and Data Architecture
Enterprise Architecture (EA) is a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. EA applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes.
In IT, data architecture is composed of models, policies, rules or standards that govern which data is collected, and how it is stored, arranged, integrated, and put to use in data systems and in organizations. Data is usually one of several architecture domains that form the pillars of an enterprise architecture or solution architecture.
Portfolio Management/ Capital Planning and Investment Control (CPIC)
IT portfolio management is the application of systematic management to the investments, projects and activities of enterprise IT departments. Examples of IT portfolios would be planned initiatives, projects, and ongoing IT services (such as application support). The promise of IT portfolio management is the quantification of previously informal IT efforts, enabling measurement and objective evaluation of investment scenarios. CPIC is an IT governance and management methodology for selecting, controlling and evaluating the performance of IT investments throughout the full lifecycle.
