5 The Issues IBM Software Symposium 2006 Design of technical systems can be an extremely complex problem High probability of failure Fundamental complexity due to: Functionality Concurrency Asynchrony Distribution Multiple disciplines Scale Accidental complexity due to: Semantic gaps Lack of skilled developers Incompatible tools Inadequate tools Disconnected processes 5

6 Agenda The Systems Space Definitions and Issues Governance and Product Development Tools Strategy 6

7 Fitting Systems Development into the Business Process A sound business process is Measurable Predictable Repeatable and has clear objectives the measurements are meaningful in terms of business objectives we have the data and knowledge to more accurately assess progress and make predictions The technical development process must fulfill to the objectives of the business process Technical decisions should be made based on business needs and priorities Ensures the delivery of the right product Development should be an integral part of the business process i.e., it should be measurable, predictable, and repeatable 7

8 What is Governance? Establishing chains of responsibility, authority and communication to empower people (decision rights) Establishing measurement, policy and control mechanisms to enable people to carry out their roles and responsibilities 8

9 The Governance Lifecycle Establish the Governance Need Document and validate business strategy for products Assess current Define/Refine vision and strategy Review current Governance capabilities and arrangements Lay out governance plan Define the Governance Approach Define/modify governance processes Design policies and enforcement mechanisms Identify success factors, metrics Identify owners and funding model Design governance infrastructure Monitor and Manage the Governance Processes Monitor compliance with policies Monitor compliance with governance arrangements Monitor IT effectiveness metrics Deploy the Governance Model Incrementally Deploy governance mechanisms Deploy governance IT infrastructure Educate and deploy on expected behaviors and practices Deploy policies 9

10 Governance and Product Development Discover Construct & Test Compose Integrate people Integrate processes Manage and integrate information Gather requirements Model & Simulate Design Business objectives alignment Process control Manage applications & services Manage identity & compliance Monitor business metrics 10

11 How IBM Facilitates Governance Experienced resource Methodology and processes to assess current capabilities and the organizations Tools and templates formulate the governance strategy Methods, processes and principles to create the Governance Model Technology to help define services and data needs, and instantiate measurements and controls Services to help develop the governance approach Dashboards for viewing business and project metrics Technology for helping measure and monitor performance Services to improve effectiveness Technology to help govern assets across the lifecycle Processes for helping enable governance Services to help implement governance mechanisms 11

13 IBM Rational Design & Construction Tools Strategy Build on open standards Eclipse, UML 2, MDA, J2EE, etc. Support multiple languages and platforms Java/J2EE, C++, XML, Provide end-to-end traceability and deep integration across roles and assets Integrate requirements, models, code, tests, deployment, defects, etc. Continuously improve lifecycle tool integrations Tools scale to complex, real-world team environments Enable asset-based development Capture, store and reuse design patterns and transformations Consolidate tools onto Eclipse platform A single tool architecture going forward Build an extensible and customizable modeling platform Using standard Eclipse mechanisms and APIs wherever possible Facilitate move to Service-Oriented Architecture Through tools, standards, processes, run-times and services 13

15 What is Eclipse? An Open Source Project eclipse.org Delivers and supports the technology A Technology Offering Universal platform for integrating development tools Open, extensible architecture based on standards Licensed for royalty free world-wide distribution A Community Commercial vendors, educators and individuals contribute to the project and technology Vendors bring commercial offerings to market Vendors work together to agree on standards and deliver integrated solutions 15

16 Eclipse: Who s Shipping or Supporting It? TimeStorm Integrated Development Environment (IDE) SUSE LINUX Professional 16

19 Model-Driven Development (MDD) An approach to software development in which the focus and primary artifacts of development are models (vs programs) Based on two time-proven methods: (1) ABSTRACTION (2) AUTOMATION Realm of modeling languages start «sc_module» producer out1 start «sc_module» producer out1 Realm of tools SC_MODULE(producer) {sc_inslave<int> in1; int sum; // void accumulate (){ sum += in1; cout << Sum = << sum << endl;} SC_MODULE(producer) {sc_inslave<int> in1; int sum; // void accumulate (){ sum += in1; cout << Sum = << sum << endl;} 19
