For further details see Chapter 6 of this document. UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 1
  2. 2. syseng/05-05-01 1 2 3 4 5 6 SPECIFIC REQUIREMENTS ON PROPOSALS This section lists the specific requirements for a UML Profile for DODAF/MODAF (UPDM) that provides an industry standard UML representation for DODAF v1.0 architecture products and supports evolution to DODAF v2.0. Utilizing a common modeling language with a standard architecture framework will significantly enhance the quality, productivity, and effectiveness associated with architecture and system of systems modeling, including improved communications, model/data reuse, and tool interoperability; and will reduce re-training requirements for different tools and projects. 6.1 PROBLEM STATEMENT The current DODAF v1.0 Volume II includes guidance for representing DODAF architecture products using UML. However, this guidance is not sufficiently precise or complete. The current guidance has been interpreted many different ways by architects and users of this framework and by vendors who are implementing DODAF in their UML tools. As a result, the DODAF UML representations do not fully serve their intended use to support communications among stakeholders and re- use of the architecture products and data. The different vendor implementations also result in interoperability issues between tools, and additional training requirements for the users. In addition, UML v1.x has been superseded by UML v2.0 that is currently being augmented with a Systems Modeling Language (SysML) profile for Systems Engineering. The latter provides a much more robust system of systems modeling capability. UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 2
  3. 3. syseng/05-05-01 Work is currently underway to evolve DODAF v1.0 to DODAF v2.0. This may add new requirements for the UPDM. DODAF v2.0 will define several overlays that support key transformational processes (e.g., acquisition, budgeting and portfolio management) and must maintain architectural consistency across the overlays. [Editor’s Note: elaborate on DODAF v2.0 requirements as they become available]. MODAF is the UK equivalent of DoDAF tailored to meet the needs of the UK Defence community. The UK MOD have built upon the DoDAF views and introduced two new Viewpoints covering Strategic Capability (High-level User requirements and Enterprise capability trade-offs) and Acquisition (Programmatic) issues. These new developments are likely to be used by the International community in the future, when data is exchanged, and so need to be considered in the development of the profile. 6.2 SCOPE OF PROPOSALS SOUGHT The scope of this RFP is for a UPDM that satisfies the requirements outlined below. This includes representations for DODAF/MODAF views and products for modeling of the systems architecture (Systems View) along with their associated standards (Technical View) within the context of the business or enterprise architecture (Operational View). In addition it should be able to represent the UK modeling of the capability and strategic intent of the Enterprise (Strategic View) and the programmatic associated with the procurement of defense systems (Acquisition View). It should also provide a sufficiently robust capability and enhancements needed to support newly defined requirements for DODAF v2.0. Section 6.5 includes the following categories of requirements for the UPDM: • Meta-model (abstract syntax and constraints) • Standard Notation (concrete syntax) • Views and Viewpoints • Architecture products • Extensible library of reusable architecture elements and patterns • Standard data interchange mechanism (e.g., XMI) Submitters may provide partial responses to these requirements, along with a roadmap to address the complete requirements. The evaluations will assess the level of completeness as part of the evaluation criteria. It is expected that follow-on RFP’s may include additional and refined requirements as the user and vendor communities learn from their experiences in applying the profile. UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 3
  4. 4. syseng/05-05-01 The intent is to use the UPDM to directly model architectures for a broad range of complex systems, which can include hardware, software, data, personnel, and facility elements. Such an architecture model must support the analysis, specification, design, and verification of complex systems, and is intended to improve the ability to exchange architecture information amongst tools, and to help ensure consistent modeling from the system of systems level down to lower levels of design and implementation. The profile should provide the modeling of operational activities, nodes, systems, hardware, software, and organizational components, interfaces, system functions and services, performance, and physical characteristics. In addition, the profile should allow for the modeling of operational views that span the full spectrum of Doctrine, Organization, Training, Materiel, Leadership & education, Personnel, and Facilities (DOTMLPF and the UK MOD equivalent Lines of Development). The additional MODAF views (and possibly DODAF v2.0) will also introduce a requirement to model capabilities, services, projects, system ports, protocols, physical properties and units of measure. Any profile should take into account aspects of the physical world that UML has not previously addressed. These include usages of systems (i.e. a type of system being used in an assembly structure) and instances of systems, nodes, etc. A great deal could be learned from the SysML experience in this area, as well as from ISO10303 STEP. An extension of UML in response to the UML for Systems Engineering RFP is currently being developed based on UML v2.0 to support the specification, design, and analysis of complex systems. This extension is called the Systems Modeling Language (SysML), and is expected to begin adoption by the OMG in 2005. SysML should provide a foundation for the UPDM to support modeling of system of systems. (Editor’s Note: We expect SysML to be used for this RFP even though it is in draft version at the time of this RFP publication. We expect SysML to be formally adopted before submissions to this RFP are due.) If additional extensions are needed, the UPDM must rely on extension mechanisms provided by UML and MOF. A profile selects and constrains the use of existing UML modeling elements, optionally with new terminology and notations specific to that profile. Other extension mechanisms provided by the UML and MOF specifications may also be used, such as defining new types of UML modeling elements and model libraries. A combination of these extension mechanisms may be used as well. For further information about the mechanisms that UML provides for its own extension, see the specifications referenced in Section 6.3 below. 6.3 RELATIONSHIP TO EXISTING OMG SPECIFICATIONS Proposals may reference and build upon any of the OMG specifications identified in this section. In each case, the most recent version is applicable, unless the most recent version was adopted less than six months before the final submission to this specification, in which case the previous version may be used. Proposals should identify the specific dependencies they have on any of these specifications including UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 4

Detailed, up-to-date web links for each of the related activities, documents, and standards summarized in the sections below are provided at 6.4.1 DoDAF v2.0 DoDAF v2.0 is currently in development, and will focus on defining several overlays to support key transformational processes (e.g., budgeting and portfolio management). To maintain architectural consistency across the overlays, an underlying meta-model of architecture elements and relationships is maintained. The specific requirements for DODAF v2.0 will be incorporated as they become available. 6.4.2 MODAF MODAF is the UK Ministry of Defence Architecture Framework. It is based on DODAF with some minor changes to TV-1, OV-1, OV-2, SV-1 and SV-2. In addition to this, MODAF adds two new viewpoints: UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 5
  6. 6. syseng/05-05-01 Strategic Capability Views – these views define the high level capability vision and strategic intent, the capabilities and sub-capabilities (capability functions) required to support that vision. In addition, the dependencies between capabilities, the phasing in and out of systems that support the capabilities (planned time periods of capability), and the organizations in which those systems are to be deployed are also covered. Acquisition Views – these views define the project team structures required to deliver network enabled capabilities (cf NCW). They also define the inter-project dependencies and specify the lines of development status (cf DOTMLPF) at significant project milestones. The UK has aligned the usage of an Architecture Framework to its Communities of Interest (CoI’s) processes, e.g. how MODAF should be used by those involved in Acquisition of Concepts & Doctrine. This approach increases the need to exchange data between the CoI’s. MODAF has begun to develop a UML profile – initially to support XMI-based file exchange between MODAF tools and repositories. The profile covers the whole of MODAF, and is therefore a superset of DODAF. 6.4.3 ISO 10303 (STEP) - AP233 ISO 10303 – AP233 (AP233), the Application Protocol for Systems Engineering, is focused on developing a neutral data format to exchange systems engineering information among tools. AP233 is being standardized under the ISO TC-184 (Technical Committee on Industrial Automation Systems and Integration), SC4 (Subcommittee on Industrial Data Standards), and is part of the larger STEP effort, which provides standardized models and infrastructure for the exchange of product model data. The UPDM development should be closely aligned with the on-going development of AP233, especially in the area of systems, because AP233 is being evaluated as the preferred protocol for exchanging architecture data between tools that are based on the CADM schema and tools that are based on other meta-models, or the MOF. 6.4.4 IEEE 1471 This recommended practice addresses the activities of the creation, analysis, and sustainment of architectures of software-intensive systems, and the recording of such architectures in terms of architectural descriptions. A conceptual framework for architectural description is established. The content of an architectural description is defined. Annexes provide the rationale for key concepts and terminology, the relationships to other standards, and examples of usage. [IEEE 1471] Appendix 3 presents the IEEE 1471 definitions as used in this RFP. UML Profile for DODAF/MODAF RFP – DRAFT May 30, " 6
