What is release management?
and why should I care?

What?
Release Management
Why?
Reduce Risk
“This just does not work
for me” – Sales Executive
“I just thought it would look
a little different than this” –
Operations Manager http://blogs-images.forbes.com/glennllopis/files/2011/04/risk.jpg
Increase Stability
“Rajan fixed the bug in the case page rendering but introduced 2
others!”
“That change that Srini made has stopped people entering orders!”
“It tested fine in the UAT environment, so why is
production down!”
All While Improving Throughput!
Backlog
Steve is the…..

How good is your release process?
No regression
Zero bugs
100% user satisfaction
Your backlog is always empty
(“the business” users just cannot fill
it!).
Rollback – what’s that?!?
You would let Dr. Evil (and mini me!) mess
with your org, knowing your tests will pick up
bugs… ??
5 Principles for Large Organizations
DiQUAD
Principle #1
Define an Environment Strategy upfront
Hint: Ad-hoc sandbox proliferation is not good.
Plan for
LDV

Principle #2
Bring the pain forward
Integrate code early in the development process
The Tools
Everything You Need to Build
Apps
Eclipse Force.com IDE
Instantly Set Up Dev Environments
Force.com Sandbox
Easy Access to Code and Schema
Metadata API
Change Sets
Easy Tool for Admins to Migrate Changes
Continuous Integration
Continuous Integration (CI) is a technique used to quickly identify the many
issues that arise when integrating code. Code repositories and build servers are
core components.
Demo Continuous Integration
Principle #3
Build Quality In
100% Code Coverage is not enough!
William Deming: “Cease dependence on mass inspection
to achieve quality. Improve the process and build quality
into the product in the first place”
Build Quality - Best Practice
Diagram invented by Brian Marick
Demo Regression Testing
Principle #4
Measure, measure, measure!
Impact of change
Measure, Measure, Measure
Measurement How?
How much change is happening?
Source code deltas
How often is it happening?
Release cycles
What types of change?
Triggers, pages, fields, workflows etc.,
What are the results of those
changes?
# of bugs introduced, severity of bugs,
downtime (in minutes, in dollars),
Measure: Value Stream Mapping
Principle #5
Lather, Rinse and Repeat
Automate Deployment
Summary
Define an environment strategy upfront. Plan for LDV.
Bring the pain forward. Integrate code early.
Build quality in. 100% code coverage is NOT enough.
Measure. Measure. Measure.
Lather, Rinse and Repeat. Automate Deployments.
