e-development Accelerators: The Problem
Internet requires shorter development cycles At the same time, software
Has a broader audience
Must be higher quality
This is the “Software Development Paradox”
Higher Quality
Faster Time to Market
IBM Software Group
e-development Accelerators: Objectives
Ensure customer success Objective: Application Assembly
Jumpstart application development
Reduce reliance on hand-crafted artifacts
Achieve financially significant re-use
Promote asset-driven development Automation for harvesting, managing, and assembling reusable assets
Advanced code and test generation from patterns or templates
Public and private marketplaces of standardized reusable assets
IBM Software Group
Why now? Why Rational?
Maturing software engineering practices Unified Modeling Language Rational Unified Process Capability Maturity Model (CMM)
Industry Standardization Platforms (e.g. J2EE, .NET) Protocols (TCP/IP, HTML, XML)
Application Frameworks (e.g. Weblogic Commerce Server, SAP, WebSphere)
Critical shortage of application developers Why Rational?

Reusable Software Asset - Definition
What is a software asset?
In general terms: a reusable software asset is a software artifact or a set of related artifacts that has been created or harvested with an explicit purpose of applying it repeatedly in subsequent, separate development efforts.
Examples:
EJB or COM Component with artifacts describing them e.g. Model, Test Scripts
Requirements Framework – Net Edition
Architectural Mechanism – Using JDBC for Persistency
IBM Software Group
Reusable Software Asset - Structure
Classification part describes the assets using meta-tags. They are used to group, store, search and retrieve assets.
The Usage part contains key information about how to apply the asset
The Solution part contains the artifacts that comprise the solution
An Asset is a set of artifacts. These artifacts have to be described and packaged for reuse into an Asset Package.
Overview describes the problem that the asset solves as well as the intent and motivation.

Customization to Fit Your Environment
The Reusable Asset Specification can be customized in the following areas:
• Artifacts• Asset Categories • Asset Structure• Meta Tags• States and Values
The required elements of an asset as declared in the specification cannot be removed
IBM Software Group
Rational ClearQuest: Extend Asset Support With Hooks
Hooks provide the capability to automate and enforce your process Written in VBScript or Perl using Built-in Editor Examples:
Add “Browse” button to web publisher reference – add a hook to launch referenced web published model
Similar hook to open up Rational ClearCase view and browse the assets
Upon creation of Asset could add a hook to generate the directory structure required
IBM Software Group
Creating the Asset Reference
Needs to be a lightweight process Simple and quick forms
Use context menu of ClearCase for data collection
Use ClearQuest API to add record
Use ClearQuest API to show record form when required
IBM Software Group
The Original Requirements List
Support for a catalog or library of Assets Browsing Capabilities – to find appropriate assets
• Textual & Visual Descriptions of Assets Multi-user support
• Support for distributed teams Configuration Management capabilities
Asset Traceability
• Support for Impact Analysis when changes required
• Provide Metrics on usefulness of assets
Facilities to register developer interest in components Supporting environment to Utilize Assets
Needs to support a variety of assets
IBM Software Group
Providing Support for Traceability
We need to provide traceability to the projects/systems that use these assets
Create record types for project/systems
Trace the assets to the systems that use them
• Provides support for Impact Analysis
• Give us the capability to provide metrics on usefulness of Assets
Facilities to register developer interest in components Create Enhancement Request Record type
Use this to register enhancements requests for new or existing assets
IBM Software Group
Why use Rational Suite?
Provides the capability to manage a variety of assets Components Frameworks Architectural Mechanisms Guidelines, white papers, requirement frameworks
Provides the capability to manage supporting artifacts Requirements Designs Tests Implementation
Provides the supporting environment to Utilize Assets on a Project

SuiteSummary
IBM Software GroupSummary
Rational is driving the e-Development Accelerators initiative focusing on 3 areas: Reusable Asset Frameworks
Automation
Reuse Standards – RAS
Today with Rational Suite we can capture: Asset Catalog using Rational ClearQuest for textual descriptions and Rational Rose for
visual descriptions
Asset artifacts using Rational ClearCase
Rational Suite also provides the environment to utilize these Assets
