ALM and Change Management at IBM

Many tools to integrate

Solutions require it

Products are: New

Legacy

Acquired

ISVs and Partners

IBM Rational Software Conference 2009

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 areas Change Management Focus of this talk

Quality 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 defect

Agile planning of change requests

Technical capabilities: Discovery of services

Metadata is not needed (resource creation and selection is delegated)

Minimal resource definition

RESTful resource manipulation: create, modify

IBM Rational Software Conference 2009

SLI04 12

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 Selection A way to pick (search for and select)

Resource Creation Use 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

OSLC - Interoperability in Heterogeneous Landscape

TasktopCompany behind Eclipse Mylyn has joined OSLC

Tasktop Pro is the commercial version of Mylyn + ALM integrations

Both open source and closed source tools leveraging OSLC

DemosTask-focused programming

Task creation via OSLC (open source)

ClearQuest integration via OSLC (closed source)

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 tool

Monitoring project health

Technical capabilities: Providing metadata about resources (schema)

Handling attachments to change requests

Seamless interaction with state models
