2 2 Architecting and Engineering Different Sides of the Same Coin Engineering employs analysis of function to iteratively decompose and separate a primarily functional representation of a whole into representations of economically producible components that can be assembled to construct the functional whole. Big implication here! Engineering requires an initial point - a representation of the whole to be successful! Engineering does not work without an initial point!! We refer to this initial point as: Engineerible Requirements The set of engineering requirements necessary and sufficient to initiate the successful engineering and production of a system Brad Mercer, MITRE, Chief Architect Maritime IT and Engineering

3 Architecting and Engineering Different Sides of the Same Coin Architecting employs synthesis of form to iteratively compose separate elements to form a coherent whole, or a representation of a coherent whole, that can serve as an initial point for system development. Architecting synthesizes this initial point from the collective vision, goals, constraints, and other needs of the stakeholders in the to-bedeveloped system converting conflicting stakeholder demands into a conceptualized whole that maximizes the satisfaction of each stakeholder. From the point of view of architecting, we refer to this engineering initial point as an: Architecture Specification An architecture description to which all system implementations must adhere; and a set of principles, practices, and constraints guiding implementation, operation, and evolution of the developed system Phone Brad Mercer, MITRE, Chief Architect Maritime IT and Engineering 3

6 6 Root Process Problem Complexity of data elements is overwhelming Difficult to support the book-keeping management of all of the data elements and their relationships across all the echelons of the Enterprise Structuring complexity Echelon integration and enterprise description everything is a part of a larger system Persistent, iterative, and evolutionary incorporation in a knowledge and reuse environment

7 7 Discovery Every object, relationship and aggregation of objects in the knowledge metamodel is in documents, the universe of textual models Discovery is about finding the objects, relationships, aggregations and descriptions of each of these in the authoritative and original data sources Integration is about using Discovery to build and describe the Architecture using an architecture meta-model

8 8 Concept, Themes, and Description A concept, or theme, is the encapsulation of a pattern that is identified as a gestalt: a persistent and unique signature Documents are textual patterns Models are labeled, structured patterns Labels are knowledge anchors to concepts and themes Knowledge is pattern recognition, association and application in integrated textual and model gestalts

9 9 DISCOVERING CONCEPTS / THEMES ' can be treated as quantifiable symbols in communications Natural language has a high degree of unessential content, the less frequently a unit of communication occurs, the more information it conveys objects extracted from Natural Language text form a index unique to that concept The architecture metamodel is the syntactic of the knowledge pattern and is semantically rigorous objects cluster based upon an inference relationship measuring semantic completeness

10 Mapping and Demonstrating Impactful Relationships 10 Cluster the indexes of the information objects using Statistical Inference! Example Cluster Picture from the Cartia: ThemeScape Web Site Define the information objects and index them Program Reportingphone company Object McKinsey #1Consulting Program Reporting VoIP (Voice-over-IP) Object #N Info-Tech Research Program Reporting Object #2 Program Implementation Baseline standard phone lines VoIP (Voice-over-IP) Legacy and low-end VoIP systems de facto standard misnomers and myths Program Reporting Object #R Long distance call THE UNIVERSE OF DOCUMENTS CONTAINS THE INFORMATION OBJECTS THAT DESCRIBE THE IMPLEMENTATION BASELINE

12 DISCOVERY PROCESS Theory Statistical Inference 1.0 DISCOVER Objects 1.1 INDEX Indexed Objects Architecture Conceptual Data Model - Metamodel 1.2 CLUSTER Clusters Semantic Completeness Phone ANALYZE Iterative Labeled Concept Descriptions Encapsulated Concepts 1.4 DESCRIBE Rich Concepts, Indexes and Clusters Discovery works best when it has a pre-existent form upon which it can operate. 12

13 13 ARCHITECTURE & DISCOVERY Architecture is the description of the intrinsic relationships, characteristics and behaviors of the system under study All systems have an architecture intentionally architected or not and that architecture is a primary determinant of the system s behavior. Brad Mercer, MITRE Principal Architect Architecture is the model in Modeling and Simulation and a rigorous and well-constructed model can be executed Discovery: the process for identifying the conceptual syntactic of architecture and the rich semantics Present architecture efforts are neither semantically complete nor rich: they contain a series of model artifacts (products) built and limited to labeled components and relationships; it has no processes, only product templates

14 14 Taxonomies of Primitives Indexing and clustering builds initial identification and organization of labeled themes and concepts Clusters are labeled taxonomical elements Rich taxonomies can be developed from clusters Structured and organized categorization of information Syntactic and semantic descriptions Parent child relationships Labeled themes and concepts are the architecture primitives

15 Topologies in Domains (information, behavioral, functional) 15 Topology in architectures relates to the connectedness of child child with order of precedence and importance object references contain topological reference information useful in describing and identifying the syntactic and semantic elements The taxonomical and topological elements provide the structure and precedence of concepts and their references provide the content for specification

16 Persistence (Primitives) and Re-use (Encapsulations) 16 To be Persistent, the model must decompose to its fundamental components, its primitives. Activity Rules x Consumed Data or Message State Activity y Produced Data or Message IDEF0 MODELS mix component information and concerns and are a visualization standard, not a data standard. Aggregation y = f(x) Op At a Node Node For a Given State According to a set of rules To be Re-useable, the model must encapsulate its fundamental components, or primitives into re-useable Objects.

17 17 Enterprise Decomposition by Echelon x Rul e 1 f(x) Oper Node A y x f(x) Rul e 1 f(x) f(x) f(x) 1.De-confliction of meta-model components to remove mixing of concerns 2.Encapsulation represents the statement of a gestalt. 3.Incremental instances of encapsulation represent Rules and States. 4.Decomposition is a basic principle of Architecting and Engineering Oper Node A.c Oper Node A.a Oper Node A.d Oper Node A Decomposition Oper Node A.b f(x) Decomposition f(x) 1. Decomposition is Echelon by Echelon: as two separate synchronous taxonomies 2. Functional Decomposition is done with IDEF0, and the Operational Node Decomposition is done synchronously to this 3. Inputs-Output of the IDEF 0 Model and their mapping to the Node Model are the Flow Model. These Inputs-Outputs are the Elements that provide topological reference, precedence of function and critical exchange information for interoperability concerns 4. This process PROVIDES THE RIGOR for the architecture primitives. y

19 19 DISCOVERY ENABLED ARCHITECTURE SPECIFICATION Document information objects describe the taxonomy and topology of architecture primitives and relationships Integration is accomplished using the principles and practices of a tightly coupled discovery-based architecting process Indexing and Clustering provide navigation to the authoritative and original sources for descriptions of the information objects Clustering, using these descriptions, iteratively refines and extracts more relevant information objects This enables the Synthesis of Form Discovery described Architectures enables the development of Rigorous, Semantically complete Architecture Specifications, i.e., engineerible requirements This enables the Analysis of Function
