1 Operational, Services, Performance, and Functionality (OSPF) Architecture View An Executive-Level Enterprise Depiction 24 February 2009 Bruce J. Brown Director, Architectures Advanced Technology Group

2 2 Why a New View? Current architecture products are fragmented into different views making an understanding of the enterprise difficult to grasp, especially for executives Typically overview OV-1 and SV-1 are overly simplistic, while other views too microscopic; hence: cant see the forest for the trees Desire to show key components of the enterprise and relate to functionality and performance View facilitates an understanding how subsequent enhancements impact functionality and performance

3 3 Operational, Services, Performance & Functionality (OSPF) View Example (As-Is Baseline) Performance & Features (SV-7) 2M User Size 2 sec Resp. Time Biometric Security.9999 Availability Functionality (OV-1,UML Use Case) Search IM Records Access Acronyms & Abbreviations IM: Instant Messaging Scope (AV-1) Segment 1 Segment 2 Segment 3 Core Diagram (SV-1, SV-4/5, UML/SysML Structure) Data Stores Services & Business Process Network & Security Portal Presentation Mail Access & Routing Search Engine Messaging Service Warehouse Service [Magic DB] Sign On Sessions How well does it work? What does it do? Who are the users? What are the key services & components that make it work? What specific services/components support this functionality? Identity Mangement What applications support the service? What part of a larger enterprise, if any, does this view cover? Selection of Core Objects: - Supports prime functions - Supports performance features - Object in Sequence Diagrams - Arranged in structured format

4 Performance & Features (SV-7) 2 sec Resp. Time 2M User Size Biometric Security.9999 Availability Functionality (OV-1,UML Use Case) Operational, Services, Performance & Functionality (OSPF) View (To-Be Target) Search IM Records Access Scope (AV-1) Segment 1 Segment 2 Segment 3 Core Diagram (SV-1, SV-4/5, UML/SysML Structure) Data Stores Services & Business Process Network & Security Portal Presentation Mail Access & Routing Search Engine IM Service Warehouse Service [Magic DB] Sign On Sessions How well does it work? What does it do? Who are the users? What are the key services & components that make it work? What specific services/components support this functionality? Identity Managment Video Service Video 1 sec Resp Time = New performance, functionality, services and components Cache Upgrades to baseline traceable to services & components What part of a larger enterprise, if any, does this view cover? What applications support the service? View makes it easier for executive decision-makers to understand how upgrades/changes impact functionality and performance Acronyms & Abbreviations IM: Instant Messaging

5 5 Sequence Diagram Example (UML; OV-6c; SV-10c) How does it work?

6 6 Insertion of Products into Tool* OSPF Custom View Sequence Diagrams Standards New AV Views Data Models New AV Views AV Custom Views for Glossary Acronyms Requirements Wiring Diagrams Process Diagrams * Sparx Systems Enterprise Architect

7 7 Proof of the Pudding… Sequence Diagrams OSPF Diagrams Sequence Diagrams Sequence Diagram OSPF Diagram

8 8 Summary New high-level enterprise view consisting of summarized performance, functionality, and services/systems related by traceability indicators with change/enhancement markers Can be harmoniously integrated into existing MODAF/DODAF frameworks & toolsets. Sequence diagrams enhance the view Additional tailored architecture views may be added to further improve understanding and achieve tighter integration with requirements Purpose: Reusable products; facilitate communications across the team; improved executive-level understanding of the enterprise Goal: Higher customer acceptance and usability of architecture products
