Some of the questions to answer are: Bringing dolls to life. If your program is developing models for large systems supporting missions and businesses with time-sensitive needs, insight into system behavior is crucial. This can either confirm an architectural approach for application to real-world situations or be the basis for refinement that better aligns the architecture with operational reality. Is a disciplined architecture approach embedded in the primary tool my team will be using, as in the case of Activity-Based Modeling (ABM) being embedded in system architect, or do we have to enforce an approach ourselves? There is an investment associated with having a "living" architecture that contains current information, and differing levels of abstraction and views to satisfy all stakeholders. This entails several processes that are not provided for in traditional SE practice. Will there be a need to tell others how the system works? Will there be a need to assess the system's viability to contribute to future mission needs? MITRE SEs should be actively involved in determining key architecture artifacts and content, and guiding the development of the architecture and its depictions at the appropriate levels of abstraction or detail. Often, multiple models and non-model artifacts are generated to capture and track the concerns of all stakeholders. By using models as an analysis tool yourself, particularly in day-to-day and key discussions, you maintain focus on key architectural issues and demonstrate how architecture artifacts can be used to enable decision making. Presented at 20th Anniversary International Council on Systems Engineering (INCOSE) International Symposium, July 12-15, 2010, Chicago, IL, USA. The INCOSE Competency Framework provides a set of 36 competencies for Systems Engineering within a tailorable framework that provides guidance for practitioners and stakeholders to identify knowledge, skills, abilities and behaviors crucial to Systems Engineering effectiveness. To prevent duplicate efforts in describing a system using multiple frameworks, establish overlapping description requirements and ensure that they are understood among the SEs generating those artifacts.

It is primarily developed by Donald Firesmith and first published in 2008.[1]. Refer to the SEG Approaches to Architecture Development article for guidance on for model characterization. Definition: An architecture framework is an encapsulation of a minimum set of practices and requirements for artifacts that describe a system's architecture. Today, many architecture tools support the development of executable models easily and at reasonable cost. Once the frameworks have been chosen, the models and views will need to be determined. For the engineer and project manager it provides a basic framework for planning and assessing system development. This source is considered a primary reference for the following articles: Traditional systems engineering (SE) is performed on a development project with only one or a few related systems being developed. The resources and time required to create architecture views may be seen as not providing a commensurate return on investment in systems engineering or program execution. Keep it simple.
