DRAFT Analysis to Date Summary of Issues • Redundancy and Ambiguity – Ambiguous relationship between Architectural Descriptions (AD) and Systems Engineering (SE) products – Inadequate specificity in SE document standards (e. g. DIDs) relative to Architecture data, models and descriptions used in requirements and architecture Documents (e. g. ICD, CDD, ISPs) • Governance – Ambiguity regarding the role of AD in SE processes (Requirements documents, Mil. STD-881 C) – Inconsistent precedence and use of Do. DAF models in SE documents – SE specification documents are not standardized across Components (e. g. SDS, SRD, PS, Mil-STD-961 DIDs) – Inconsistencies in OSD SETR Guidelines and SE Guidance relative to Do. DAF and architecture* • Traceability – Inadequate traceability between AD and SE artifacts – Inadequate traceability between below the document level (not consistent amongst Components, Programs and Projects) *DEFENSE ACQUISITION PROGRAM SUPPORT METHODOLOGY, Version 2. 0, January 9, 2009 “ 4. 1. 3. C 2: The technical system architecture descriptions should use mandated Operational View (OV), System View (SV), and Technical View (TV) products as described in the Do. DAF, and should be integral to the system design. There should be System Description Documents (SDDs) and System Capability Specifications (SCSs) that address those for the system and major subsystems. ” March 2012 DRAFT 11

DRAFT Top 5 Systems Engineering Issues in the Defense Industry • Key Systems Engineering practices known to be effective are not consistently applied across all phases of the program life cycle. • Insufficient Systems Engineering is applied early in the program life cycle, compromising the foundation for initial requirements and architecture development. • Requirements are not always well-managed, including the effective translation from capabilities statements into executable requirements to achieve successful acquisition programs. • Collaborative environments, including SE tools, are inadequate to effectively execute SE at the joint capability, System-of-Systems (So. S) and system levels. • The quantity and quality of Systems Engineering expertise is insufficient to meet the demands of the government and the defense industry.

DRAFT Summary of Issues and Improvement Opportunities -From POA&MIssue The relationship between AD and SE products is ambiguous resulting in redundant effort The relationship between Do. DAF models and SE documents is too coarse resulting in inadequate traceability between AD and SE artifacts. Governance is not standardized across the Components indicating ambiguity regarding the role of AD in SE processes. The precedence of Do. DAF models and SE documents is inconsistent. SE documents are not standardized across Components. Traceability below the document level is not consistent amongst Components, Programs and Projects. March 2012 Opportunity Do. DAF 2’s greater semantic precision compared to prior Do. DAF versions can be used to clarify the relationship. The DM 2 provides a means to define the relationship Do. DAF 2’s disambiguation through the DM 2 and current model description technical edits offer an opportunity for standardization Do. DAF 2’s reification model provides an opportunity to specify precedence of model and artifact types at an appropriate reification level. Mapping to the unambiguous and precise DM 2 and Do. DAF 2’s reification levels can lead to standard definitions of SE documents. The DM 2 can provide explicit relationships at the document content level that can substantially improve requirement traceability between the various reification levels and associated documents and artifacts.

DRAFT Do. DAF 2. 0 Conceptual Data Model DRAFT
DRAFT Scoping Architectures to be "Fit-for-Purpose” The architect is the technical expert who translates the decision-maker’s requirements into a set of data that can be used by engineers to design possible solutions. Establishing the scope of an architecture is critical to ensuring that its purpose and use are consistent with specific project goals and objectives. The term “Fit-for. Purpose” is used in Do. DAF to describe an architecture (and its views) that is appropriately focused (i. e. , responds to the stated goals and objectives of process owner, is useful in the decision-making process, and responds to internal and external stakeholder concerns. Meeting intended objectives means those actions that either directly support customer needs or improve the overall process undergoing change. The architect is the technical expert who translates the decision-maker’s requirements into a set of data that can be used by engineers to design possible solutions. At each tier of the Do. D, goals and objectives, along with corresponding issues that may exist should be addressed according to the established scope and purpose, (e. g. , Departmental, Capability, SE, and Operational), as shown in the notional diagram in the figure below.

DRAFT The DM 2 Conceptual Data Model -key concepts • • Activity: Work, not specific to a single organization, weapon system or individual that transforms inputs (Resources) into outputs (Resources) or changes their state. Resource: Data, Information, Performers, Materiel, or Personnel Types that are produced or consumed. – Materiel: Equipment, apparatus or supplies that are of interest, without distinction as to its application for administrative or combat – purposes. Information: The state of a something of interest that is materialized -- in any medium or form -- and communicated or received. • • – Performer: Any entity - human, automated, or any aggregation of human and/or automated - that performs an activity and provides a capability. • • • Organization: A specific real-world assemblage of people and other resources organized for an on-going purpose. System: A functionally, physically, and/or behaviorally related group of regularly interacting or interdependent elements. Person Type: A category of persons defined by the role or roles they share that are relevant to an architecture. Service: A mechanism to enable access to a set of one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description. The mechanism is a Performer. The capabilities accessed are Resources -- Information, Data, Materiel, Performers, and Geo-political Extents. Capability: The ability to achieve a Desired Effect under specified (performance) standards and conditions through combinations of ways and means (activities and resources) to perform a set of activities. Condition: The state of an environment or situation in which a Performer performs. Desired Effect: A desired state of a Resource. Measure: The magnitude of some attribute of an individual. Measure Type: A category of Measures. Location: A point or extent in space that may be referred to physically or logically. Guidance: An authoritative statement intended to lead or steer the execution of actions. – Rule: A principle or condition that governs behavior; a prescribed guide for conduct or action. • • Data: Representation of information in a formalized manner suitable for communication, interpretation, or processing by humans or by automatic means. Examples could be whole models, packages, entities, attributes, classes, domain values, enumeration values, records, tables, rows, columns, and fields. Architectural Description: Information describing an architecture such as an OV-5 b Operational Activity Model. Agreement: A consent among parties regarding the terms and conditions of activities that said parties participate in. Standard: A formal agreement documenting generally accepted specifications or criteria for products, processes, procedures, policies, systems, and/or personnel. Project: A temporary endeavor undertaken to create Resources or Desired Effects. Vision: An end that describes the future state of the enterprise, without regard to how it is to be achieved; a mental image of what the future will or could be like. Skill: The ability, coming from one's knowledge, practice, aptitude, etc. , to do something well. March 2012 DRAFT 30
DRAFT Do. D Systems Engineering Technical Reviews (SETRs) Do. D SETR Checklists The updated DAG will also describe and refer to these technical review risk assessment checklists. The checklists accessible in the TR CLM are being updated for Do. D usage. Seven of the checklists have been updated, and are now accessible on the SE COP. User comments and recommendations for checklist improvements are solicited. NOTE: OSD has established the policy that all of the checklists are intentionally "locked" to preclude minor question changes that may potentially change an evaluation score of "red" to something less problematic ("yellow" or "green"). Most of the Service Technical Authorities endorse this policy. If the checklists were unlocked, any program or evaluator could change the wording of a question to evoke a satisfactory response, thus potentially eliminating oversight during a technical review. The checklists are set up so they can be tailored to exclude questions that are not applicable to a given program. This can be accomplished by selecting "NA" for any given question. The checklist programming will ignore those question(s) when summing totals of each category of responses. DRAFT https: //acc. dau. mil/Community. Browser. aspx? id=25710&lang=en-US March 2012 31
