ALM and Change Management at IBM
Many tools to integrate
Solutions require it
Products are:NewLegacyAcquired ISVs and Partners
IBM Rational Software Conference 2009
SLI04
ALM Solution Pain Points
Integrations built for point-to-point products
Products can’t be updated independently
Differing (incompatible) models

Tasktop case for open services
Tremendous interest a Mylyn connector for ClearQuest
Each one-off WS API comes with a burden
Legacy ALM tools are not going away soon
Need for a common, REST based API
URL-addressable resources, loose coupling
Ecipse/Mylyn support for generic functionality

…and then there became OSLC
Open Services for Lifecycle Collaboration
Introduced at RSDC 2008
Open community contribution
Scenario driven...a minimalist approach
Divided into focus areasChange Management Focus of this talkQuality Management, Estimation & Measurement, Requirements Management, …
Solving integration in the open

OSLC Architectural Drivers
Working with RESTful architectural principles (the Web seems to scale ok)
Leverage existing standards:XML, HTTP, Dublin Core
Keep the barrier toentry for existingproducts low

Current state of OSLC Change Management
Finalized 1.0 specifications
Scenarios:Find and fix a defectAgile planning of change requests
Technical capabilities:Discovery of services Metadata is not needed (resource creation and selection is delegated)Minimal resource definitionRESTful resource manipulation: create, modify

OSLC CM 1.0 – Service Discovery- Don’t require URI building and fixed segments
URLs for services are discovered
There may exist multiple levels of context
IBM Rational Software Conference 2009
SLI04 13
OSLC CM 1.0 – Delegation
Resource SelectionA way to pick (search for and select)
Resource CreationUse POSTed data to seed a Web UI, allowing delegated, user-attended creation of change requests from a loosely coupled client
Creation and Selection rely on a simple JavaScript API to return URLs to the caller

Tasktop experiences participating in OSLC
OSLC solves a business problem for us
Process is open and participative
IP policies enable both our OSS implementation and commercial extension
Lightweight & RESTful are a good way to go
Approach will affect the ALM landscape
We’re not done yet, need repository shape...

What’s next for OSLC Change Management
Progression with 2.0 specifications
Scenarios:Aggregation of tasks in IDE toolMonitoring project health
Technical capabilities:Providing metadata about resources (schema)Handling attachments to change requestsSeamless interaction with state models
