3. Exercise: What is DevOps?
Disciplined Agile Delivery: Forming DAD Teams
Exercise: What is DevOps?
For five minutes, discuss:
What does DevOps mean to you?
What new behaviours do you need to adopt?
Instructor – prepare flipchart that looks like “DAD Roles Mapping” but without the connecting lines
- Call out individuals to suggest the mappings

Do You Have a DevOps Gap?
Production
Releases
Development
Operations
Change
Requests
Production releases are seen as risky
Collaboration between development and operations is strained
Development doesn’t appreciate the realities of operations
Operations doesn’t understand new development strategies

Why DevOps?
Decreased time to market (reduced cycle time)
Decreased cost to deploy
Improved mean time between deployments (deploy more often)
Improved quality
Improved market competitiveness
Improved decision making
Decreased time to market
Shorter Transition efforts from automation
Smaller “chunks” of work can be implemented faster
Decreased cost to deploy
Automated regression testing
Automated deployment
Streamlined release management
Improved mean time between deployments
Practices such as Continuous Integration and Continuous Delivery enable teams to deploy more often
Decreased cost to deploy enables teams to deploy more often
Improved quality
Adoption of agile testing and quality techniques such as automated regression testing, refactoring, independent testing, and many others
Agile and lean strategies are applied to enterprise architecture, enabling a more holistic view of the organization which in turn promotes greater reuse and reduction/avoidance of technical debt
Agile and lean strategies are applied to data management, improving overall data quality across your organization
Improved market competitiveness
Agile/lean teams enjoy greater stakeholder satisfaction, on average, compared to traditional teams
Streamlined operations and support provide better overall service to end users
Improved quality
Improved decision-making
Real-time insight from Development Intelligence strategies
Real-time insight from Operational Intelligence strategies
Shorter feedback cycles provided by decreased time to market enable teams to easily run experiments to discover what their stakeholders actually want

6. One View: Continuous Delivery
Practices:
Automated regression testing
Continuous integration (CI)
Continuous deployment (CD)
Canary tests
Split (A/B) tests
Operations-friendly features:
Feature toggles
Feature-level access control
Built-in monitoring
Self testing
Self recovery
This is a very common view amongst agile developers and some tool vendors. Continuous Delivery is clearly an important part of DevOps but it’s really only a streamlined version of the development part of the equation.
Continuous Delivery is one of several delivery lifecycles supported by Disciplined Agile.

7. A Better View: Agile Delivery + Operations
Multi-modal approach to software development
Operations activities are also streamlined and “leaned out”
Some teams will adopt a “you build it, you run it” philosophy, but a common operational infrastructure still required
Disciplined Agile supports several delivery lifecycles, all of which could be part of your overall DevOps strategy – It’s not just about continuous delivery, although CD is highly desirable.
Minimally, DevOps should be about streamlining development (regardless of lifecycle) and operations.

8. Our View: Disciplined DevOps
Several important points:
1. In larger organizations, release management cannot be handled by just the development teams. If you have dozens, or even hundreds, of solution delivery teams working in parallel their release efforts will need to be coordinated somehow. See
2. It’s not just about operations, but operations and support (help desk).
3. Data is the lifeblood of your organization. Operational data management should be streamlined too. Releasing database changes should also be streamlined (i.e. if it takes six weeks for your data professionals to add a column into a database, you’re not really able to release changes into production very smoothly are you?).
We need to streamline the overall flow between all of these activities.

9. Disciplined DevOps: A Definition
Disciplined DevOps is the streamlining of IT solution development and IT operations activities, and supporting enterprise-IT activities, to provide more effective outcomes to an organization.

The DevOps Mindset
Streamline the end-to-end flow
Reduce the feedback cycle
Flexible people
Multidisciplinary “generalizing specialists”
Standardized infrastructure
Automation and tools
Standardized development guidelines
You build it, you run it

11. DevOps Changes Your Relationship with the Business
Introduction to Disciplined Agile Delivery
DevOps Changes Your Relationship with the Business
Your business and IT processes must be integrated
Plans must be high-level with the details coming just in time (JIT)
Emphasize delivery of value via a consumable solution rather than transitory work products of questionable value
Schedules and estimates must be given in ranges
Traditional business approaches will eliminate most benefits of agile/DevOps
The new relationship with the business:
They must be actively involved with development all the way through the lifecycle
The greater visibility and control that they now have implies the need for greater accountability on their part
They often don’t understand the implications of what they ask for, you need to educate them
You need to demonstrate that disciplined agile delivery is not cowboy programming. It is very likely far more disciplined than their current processes
Suggested strategy:
Help your customers to understand what is expected of them and why
Business decision makers need to be coached too
Be selective about the projects you apply agile strategies to. If the business isn’t willing to step up then the project isn’t a good choice for agile

12. DevOps Critical Success Factors
Build a collaborative and respectful culture across your entire IT organization
Focus on people, but don’t forget process and tooling
Choice is good
After describing these critical strategies that support Disciplined DevOps, we’d like to conclude with what we feel to be critical success factors:
Build a collaborative and respectful culture across your entire IT organization. Our experience is that people, and the way that they work together, are the primary determinants of success when it comes to adopting a Disciplined DevOps strategy. Unfortunately, it is considerably more difficult to bring about cultural change in an organization than it is to adopt a handful of new practices.
Focus on people, but don’t forget process and tooling.  DevOps is primarily a mindset, but as you’ve seen in this article there is a large number of potential practices/strategies (yes, that process stuff) that you need to consider adopting.  In turn these practices/strategies are supported by tooling, either existing tooling that you have in place (albeit now used in a different manner) or new tooling that you will need to adopt.
Choice is good.  This article has made it clear that there are many options available to you, each of which has its advantages and disadvantages.  No single approach is perfect, and no single approach works in all situations.  You not only need to have choices, it’s incredibly good to have choices.

Parting Thoughts
You don’t just do DevOps
You must also have the DevOps mindset
DevOps improves IT’s ability to support the rest of the organization
The rest of the business needs to evolve too
You have to build DevOps for yourself
You cannot buy it
DevOps permeates IT
You don’t have a “DevOps Group”, nor “DevOps Engineers”
