ALM and Change Management at IBM
Many tools to integrate
Solutions require it
Products are:
New
Legacy
Acquired
ISVs and Partners
SLI04

7. 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
SLI04

8. IBM Rational Software Conference 2009
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
SLI04

9. IBM Rational Software Conference 2009
…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
SLI04

10. IBM Rational Software Conference 2009
OSLC Architectural Drivers
Working with RESTful architectural principles
(the Web seems to scale ok)
Leverage existing
standards:
server 1
server 2
XML, HTTP, Dublin Core
server 3
Keep the barrier to
entry for existing
products low
SLI04

11. IBM Rational Software Conference 2009
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
SLI04

12. IBM Rational Software Conference 2009
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

SLI04

13. IBM Rational Software Conference 2009
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
Tasktop
Company 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
Demos
Task-focused programming
Task creation via OSLC (open source)

19. IBM Rational Software Conference 2009
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...
SLI04 19

20. IBM Rational Software Conference 2009
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
SLI04

21. IBM Rational Software Conference 2009
Conclusion and Roadmap
