7

Fitting Systems Development into the Business Process

the measurements are meaningful in terms of business objectives

A sound business process isMeasurable

Predictable

Repeatable

… and has clear 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 processi.e., it should be measurable, predictable, and repeatable


8

What is Governance?

Establishing chains of responsibility,authority and communicationto empower people (decision rights)

Establishing measurement,policy and control mechanisms to enable people to carry outtheir roles and responsibilities


9

The Governance LifecycleDefine the Governance Approach

Define/modify governance processesDesign policies and enforcement mechanismsIdentify success factors, metricsIdentify owners and funding modelDesign governance infrastructure

Monitor and Manage the Governance Processes

Monitor compliance with policiesMonitor compliance with governance arrangementsMonitor IT effectiveness metrics

Deploy the Governance Model Incrementally

Deploy governance mechanisms Deploy governance IT infrastructureEducate and deploy on expected behaviors and practicesDeploy policies

Establish the Governance NeedDocument and validate business strategy for productsAssess current Define/Refine vision and strategyReview current Governance capabilities and arrangementsLay out governance plan

IBM Rational Design & Construction Tools StrategyBuild on open standards

Eclipse, UML 2, MDA, J2EE, etc.

Support multiple languages and platformsJava/J2EE, C++, XML, …

Provide end-to-end traceability and deep integration across roles and assetsIntegrate requirements, models, code, tests, deployment, defects, etc.

Continuously improve lifecycle tool integrationsTools scale to complex, real-world team environments

Enable asset-based developmentCapture, store and reuse design patterns and transformations

Consolidate tools onto Eclipse platformA single tool architecture going forward

Build an extensible and customizable modeling platformUsing standard Eclipse mechanisms and APIs wherever possible

Facilitate move to Service-Oriented ArchitectureThrough tools, standards, processes, run-times and services

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:

««sc_modulesc_module»»producerproducer

(1) ABSTRACTION (2) AUTOMATION

Summary

System development in the technical space is an extremely challenging and complex task

However, it is possible to eliminate much of the accidental complexity involved in the development of such systems through:

Establishment of a governance strategyIntegrating development within the governance processUse of model-driven development and corresponding tools

The IBM Rational tools strategy is based on the above approachComprehensive solution that addresses all aspects of both governance and system developmentUse of open standards Based on the “software development platform” architecture that allows customization for specific domains and integration of best-in-class tools
