Gary Gruvers masterful slide deck from the "Leading the IT Transformation" events in Boston, New York and Austin.

1. Leading the Transformation
“Applying DevOps and Agile Principles at Scale”
Gary Gruver

2.  FW no longer a bottleneck for
the business
 Development costs reduced
from $100M/yr. to $55M/yr.
 140% increase in the number
of products under development
 Capacity for innovation
increased from ~5% to ~40%

3. Requirements Scheduling Development

Waterfall Approach:
Do enough up front planning

Waterfall Reality:
Discoveries during
development and difficulties
with integration/qualification
results in frequent and
costly schedule slips

5. Agile Development Model
Plan
Qual Dev
• Fully qualified code drops on a fixed schedule
• Frequent small integrations
• Short planning and development cycles
• Delivering to a well prioritized product backlog

9. Business Objectives (Don’t “Do Agile”)
Define
your value
proposition
Understand your
cost & cycle-time
drivers
Either automate, eliminate, or engineer out the
drivers that aren’t key to the value prop

14. Business Objectives for Applying DevOps at Scale
Increase the quality and frequency of feedback
Reduce the time and resources between release branch & production
Improve deployment repeatability/env. stability
Testing in an Operational like environment as close to dev. as possible

15. Finding the offending code
What Code?
When? Are you
sure it wasn’t Bob?

16. Developing on Trunk

29. Shifting the Culture
• Getting developers to ensure every check-in to trunk is stable in a
production like environment as job #1.
• Getting development and operation teams using common tools and
environments so they share common objectives.
• Getting the entire organization to agree that the definition of done at
the release branch.
• Embrace the unique characteristics of software and design a
planning process that takes advantage of its flexibility.
