Frequent Solution Delivery Isn't Enough!

Base: n = 95, Gartner Research Circle Members who use DevOps approach


Success With DevOps Requires

Business Focus: We ARE the Business. It's NOT About IT-Centric Goals.

Culture Change: The MOST CRITICAL Success Factor (and the MOST DIFFICULT).

Continuous Improvement: Theory of Constraints, Lean and Systems Thinking.

Agile Development: Scrum, Kanban, XP.

Automation and Tooling: Including Development, Test, Release and Operations.


Highest Priority Is to Satisfy the Stakeholder Through Early and Continuous Delivery of Valuable Solutions


Consumable Solutions Are the Primary

Measure of Progress


Everything MUST Be Grounded in Customer/Business Value

Value > Costs and Risks

Who Is Your Customer?

You Actually Need to Talk With Them!


Target Must Be Valuable Business Outcomes

Become a Valued Business Partner — It's Not Just About the Code

Aggressively Manage Technical Debt

Maturity alone is worthless

Release frequency is worthless

Avoid short-term benefit that incurs

long-term operational and support cost


Dev. vs. Ops. — How Trust Was Destroyed

Go Faster

Go Slower

Objective We Must Therefore

In Order to Be

Successful

The Team Reflects … Then Tunes and Adjusts Its Behavior Accordingly


Change is the law of life, and those who look only to the past or present are certain to miss the future.

— John F. Kennedy


Augment Scrum/Kanban With XP Practices

Simple design: Write minimal code that satisfies the user story

Small releases: Develop in a series of small, frequently

updated versions

Testing: Write the tests first and then write the code, e.g., TDD, BDD

Refactoring: Regularly adjust and improve the code

Pair work: Code and tests developed by two people working together

Continuous integration (CI): Provide continuous feedback on the

readiness of the solution

Collective ownership: No one person owns or is responsible for

individual code segments


Continuous attention to technical

excellence and good design enhances agility.
