1 Applying the Systems Engineering Method for the Joint Capabilities Integration and Development System (JCIDS) Chris Ryder and Dave Flanigan 27 October 2005

2 Purpose JCIDS prescribes a joint forces approach to identify capability gaps against current force capability needs The Systems Engineering (SE) Method applies to each iteration of the systems life-cycle from capability inception through system retirement Good systems engineering practice is necessary for successfully implementing JCIDS Use of model-driven SE facilitates JCIDS throughout the systems life-cycle slide 2

5 JCIDS Events Briefing Date Functional Area Analysis (FAA) o Identify operational task, conditions, and standards needed to accomplish military objectives o Result: Tasks to be accomplished Functional Needs Analysis (FNA) o Assess ability of current and programmed capabilities to accomplish the tasks o Result: List of capability gaps Functional Solutions Analysis (FSA) o Operational based assessment of DOTMLPF approaches to solving capability gaps o Result: Potential DOTMLPF approaches to capability gaps Post Independent Analysis o Independent analysis of approaches to determine best fit o Result: Initial Capabilities Document slide 5

6 JCIDS JCIDS analytical process stresses the fundamentals for applying an effective systems engineering program by any accepted standard It guides the front-end phases of the SE process for each capability iteration o Enterprise (operational) analysis o Requirements definition o Life-cycle phase The analysts must have a thorough understanding of existing capabilities as well as the capability needs The JCIDS analysis team eventually determines the optimum combination of material and non-material alternatives to achieve the capability needs to the Battle Force slide 6

7 Systems Engineering Method Regardless of the analytical phase performed by the JCIDS SE team, o The basic application of the SE method is constant throughout the process Each SE Method activity is performed in some form in each phase of the system life-cycle slide 7

13 Problem Definition At one point in time there is a problem that must be solved due to: o Deficient capability with existing systems o Desire to improve existing performance Need to understand what the objectives are to provide the desired capability Define the operational context within the Capability Enterprise! slide 13

14 Requirements Analysis Products A clear definition of the problem A proper scope of the problem Operational context documents and data bases o Design Reference Mission o Strategy-to-Task Mapping o Concept of Operations o Physical Environment Database o Threat Representation Database o Blue Capabilities Database Relevant Operational Views Captured within a SE Requirements Model slide 14

16 Functional Definition Products Functional Decomposition of required activities o Functional diagrams (FFBD, UML AD) Associated metrics with these functions (threshold / objective?) Analysis process that determines if you can solve with a material / nonmaterial / both solution o Be able to document and defend this process How do we know it s right? o The functions are legitimate, correct, and validated by users Functional Area Analysis Relevant operational views Functional Analysis Documented in a SE Functional or Logical Model slide 16

20 Design Validation Products Demonstrate the analysis documents the assumptions, follows a rigorous process, and arrives at meaningful conclusions that are justifiable o There may be multiple processes and products dependent on the sponsor, personnel/time availability, experience o This may be an iterative process for ICD, CDD, CPD Trade studies VV&A Risk Management Cost Analysis Force Allocation Functional Solutions Analysis Program Independent Assessment Attain a Fully Validated Systems Engineering Model slide 20

21 Architectures in JCIDS Briefing Date Integrated Architectures are a foundation for the analytical process o Stated requirements, attributes and measures Direct reference to DoD Architecture Framework (DoDAF), however: o Architecture is misused term within the realm of SE It is important to differentiate architecture from architectural views The JCIDS SE Model is the foundation for the architecture and the architectural views slide 21

22 Systems Engineering Model Model is a simplified view of a complex system o Assists stakeholders, including engineers, to understand something that is not easily comprehensible o Communicates the organization of the system to the stakeholders Rechtin o Contributes to the structural stability of a system. o Enhances understanding of interfaces, relationships, operations and risk If you don t model it, you won t understand it. Ivar Jacobson slide 22

23 Model-Driven SE An Systems Engineering model captures the essential elements of the systems engineering life-cycle Dynamic and recursive process (Bootch, Rumbaugh, Jacobson) o Iteratively captures enterprise capabilities and systems requirements o Promotes incorporation of technology evolution Forms basis for a sound, long-term SE and analysis o Fully compliant with precepts of DoDAF and JCIDS Model-Driven SE in Defense Systems Acquisition becomes Model-Driven JCIDS slide 23
