1 Welcome. Introduction to DevOps for Business Analysts Chris Knotts, PMP ASPE Training and Techtown Training

2 I ll discuss A little about DevOps A few examples of generic stakeholders as described in the BABOK Guide Applying the DevOps context to stakeholder roles Pain points and enablers of roles associated with successful DevOps style work

3 A few assumptions for the hour Roles are associated usually with software projects, & always with overall IT workflow DevOps is not a codified set of principles Chris is not a BA BABOK Guide 2.0 vs ?

4 DevOps & Business Analysts We will discuss: Level-set: What is DevOps? A typical enterprise environment and the life cycle of IT and software delivery projects Agility: the bridge to DevOps Continuous delivery and incremental workflows Major implications for IT project mangers

5 What is DevOps? Source:

6 DevOps IS Attribute Key Elements High-trust, highperformance culture IT capabilities = strategic assets, not cost centers Highly automated processes; mature deployment pipeline Continuous delivery of software and IT value Commitment to continuous learning & improvement Unified mission; aligned incentives across departments and teams; little fear/failure/blame, high quality of work life Projects, features and work flow through fast cycles times, systems are anti-fragile, IT processes & capabilities are aligned with overarching organizational needs Technical phases of projects supported by common tools and automation processes, collaboration replaces handoffs, codebase/it infrastructure is agile and functional by default Features, projects and IT work follow a regular, iterative flow. Cycle time is short, workflow favors small frequent changes Disciplined feedback loops quickly travel back upstream for inclusion. Tools for monitoring, measurement and alerting implemented & effective. Shared knowledge repositories.

10 Opposing missions Development teams rewarded for creating value when software is deployed Operations and infrastructure admin teams penalized for downtime

11 The triumphant Agile team! Success!! Working software or feature DELIVERED Sprints Idea

12 Opposing missions The triumphant Agile team! IT Operations Deploy & Support Operation & Systems Data Security

13 The business! (different departments, needs, stakeholders etc.) The triumphant Agile team! IT Operations Deploy & Support Operation & Systems Data Security

14 The business! (different departments, needs, stakeholders etc.) The triumphant Agile team! IT Operations!! Deploy & Support Operation & Systems Data Security Customers / end users!!

15 Lessons from Agile 1. Without a common goal, you will never achieve 2. Commit to values first the practices will follow 3. Implementing DevOps (or any new way or work) is about LEARNING not getting it perfect 4. Agile practices allow adaptability and predictability 5. Articulate a vision and get buy in from your internal customers 6. Find the MINIMUM requirements for a solution! 7. Optimize the whole! Limit work in progress (WIP) anywhere possible 8. Build great teams

16 Every member of a cross-functional team is responsible for the delivery process. One of the most important goals of a continuous delivery environment is to attach responsibility for the successful deployment of a piece of code (be it software features or infrastructure code) to the person who developed it Everyone is responsible for quality! When something is wrong (an outage, a broken build, a bug) the entire team s priority becomes fixing it Let s discuss how this works in the context of continuous integration and continuous delivery

17 Application Delivery & Cost of Defects 50% of defects introduced here

18 What are organizations trying to achieve with DevOps type practices?

19 A A simplified Welcome look to at the the an 21 st enterprise century!

20 The deployment pipeline concept Source: Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation

21 Continuous Delivery: Smaller batches of software work, more frequently, with less planning and more adaptability

25 Five of the most important roles impacted by DevOps trends Software & Enterprise Architects Software Developers IT Operations & Support Software Testers Change Managers Anyone with a stake in application outcomes!

26 Software & System Architects A few typical challenges: Legacy Technology Mission Criticality Technical Debt DevOps-associated Enablers: Service Oriented Architecture Component-Centric Design Loose Coupling of Components Simulators and Emulators

27 Software Developers A few typical challenges: Definition of done Agile Practices that end with dev teams Long, or absent feedback loops Measurement of enterprise value DevOps-associated Enablers: Agile Practices but they must scale! Deploy it yourself with operational support Treating infrastructure as code Continuous delivery of software

28 IT Operations & Support A few typical challenges: Blame from all sides Most enterprises engineered to penalize Not responsible for most defects & failures DevOps-associated Enablers: Peer-driven change management Inclusion & collaboration early in projects Technology enablers (automation tools, etc.)

29 Software Testers A few typical challenges: Accurate testing Fast enough testing People ignoring test results DevOps-associated Enablers: Designing tests as part of the product Component oriented testing Using tests to automate deployment Making quality everyone s responsibility

30 Change Managers A few typical challenges: Imposed change management Slow delivery of value Lack of leadership support Inefficiencies arising from fearful culture DevOps-associated Enablers: Peer-driven change management Engineering change as the product Leadership-driven change

31 To sum up: Stakeholders are oriented around teams and projects Quality is tied to value and is everyone s responsibility, from requirements and code creation to deployment Technical non-functional requirements (and technical debt) receive equal priority to functional requirements Deliver often, deliver early, learn and adapt. Roll planning into your continuous processes Testing and QA is not a separate function: it is a key enabler of continuous delivery Expect failure and plan for the contingency
