DevOps – The Evolution of Agile
- 1. DevOps –The Evolution of Agile
- 2. Agenda JasonTaylor, former IT Shared Delivery Director at Specsavers The role of theTest Professional in an Agile / DevOps future Simon White, M&S Group DevOps Manager Agile, DevOps &Test Christopher Livett, SeniorTest Consultant at QualiTest The Journey to DevOps
- 3. The role of the Test Professional in an Agile / Devops Future Or…………..How testing can be the catalyst for change JCT Innovations Ltd : jctinnovations@gmail.com
- 4. • 1st Testing Practice • Early adoption of outsourcing • Early adoption of automation practices • Testing Practice • Automation frameworks • Early cloud support of performance testing • Security testing • Testing Practice (6 month rollout) • Managed service • Continuous improvement • ………Testing issues start to drive change History JCT Innovations Ltd : jctinnovations@gmail.com
- 5. Should’ve gone to??????? What’s the #1 issue for Testing Services?.... Hmmm…..Where do we get data and an environment? JCT Innovations Ltd : jctinnovations@gmail.com
- 6. Environment Management Services (EMS) Year one • What have we got? • Is it documented? • How much can we virtualise? Year two • How long is our SLA? • How can we deliver more quickly? • What should we automate? Year three • End to end automated delivery • Self Service environments • Control processes JCT Innovations Ltd : jctinnovations@gmail.com +
- 7. Innovations……… | Where are the technical debt pain points? | Let’s fix them outside of projects!!!! | Automated RPM signing & RHN push from Jenkins build server | Automated configuration using Puppet | Component virtualisation using Docker | Automated Smoke Testing hardwired into the continuous integration system | Fully automated continuous integration, continuous delivery (where applicable) model for all applications | Cost savings 500 mandays effort per annum | Let’s have a DEVOPS conversation JCT Innovations Ltd : jctinnovations@gmail.com
- 8. What is Agile / DEVOPS? JCT Innovations Ltd : jctinnovations@gmail.com |Collaboration of People |Convergence of Process |Creation & Exploitation of Tools
- 9. People JCT Innovations Ltd : jctinnovations@gmail.com BA: What do you mean my requirements are ambiguous!!!! BA & Tester Developer: What do you mean my code has defects!!!! Developer & Tester Tester: What do you mean this is the first time you have seen it!!!! Tester & Ops
- 10. Process JCT Innovations Ltd : jctinnovations@gmail.com Classic SDLC • Regimented & most probably waterfall • Silo’d teams defending their patch • Is testing quality control or quality assurance? • Is OPS fix on fail or part of the process? Shift Left • Methodology agnostic • Test throughout the lifecycle and collaboratively share resources and artefacts • Is testing now quality assurance or quality control? • Is OPS now part of the delivery process?
- 11. Tools JCT Innovations Ltd : jctinnovations@gmail.com Visibility What are people doing, when they have done it and does it meet the expected standards Automation Reduce human error, risk and arbitrate delivery Collaboration Share tools, share artefacts, share knowledge and standards Measurement Measure it to ensure it meets expectations Changeability Ensure standards have been met and technical debt has not been increased Transferability Ensure movement between vendors
- 12. So what’s the role of the tester? JCT Innovations Ltd : jctinnovations@gmail.com Is it diminished? NO • Try TMMi you may be surprised at the results • Testing is everywhere / Shift Left • Testers want to collaborate Is it more important than ever? YES • Environments and applications are more and more complex • Testers have been automating for years • Are the standards and measurements required in testing understood across the lifecycle
- 13. JCT Innovations Ltd : jctinnovations@gmail.com “Efficiency is doing things right; effectiveness is doing the right things.”
- 14. So I said no more meme’s…… JCT Innovations Ltd : jctinnovations@gmail.com What your CIO might say What your Project Manager might say What your Engineers will definitely say How your testers will feel …..and finally what your developers definitely think
Editor's Notes
- Good Morning my name is Jason Taylor and I hope to give you my insight into the future if the test professional in todays lifecycle containing more Agile delivery and the concept of DEVOPS
- I am going to give you a quick run through of my History but promise it is relevant to the rest of this presentation Deutsche – Testing is a discipline Bupa – Testing is more than functional testing Specsavers – Testing becomes a driver for change
- This is me and yes this what I how I would spend my day at Specsavers musing problems, although seriously the issue that was being experienced was causing most issues when delivering testing Predictable end to end environments were simply not available
- So here’s the meme’s slide I promise this will be the only one Slide explains the 3 year journey followed by EMS + how engineering came to be and what it was trying to achieve Most importantly innovation in delivering environments led to innovations in other areas
- Innovations explained but most importantly success in these areas led to initial conversations in DEVOPS
- DEVOPS is an extension of Agile to include ops Most importantly any methodology can be limiting look at how do we deliver right first time any combination of methodology can be the right thing to do There are different start points on any methodology journey first look at what you have and pick the right entry point at Specsavers it was Environments Discuss the 3 points made but make a distinction where tools and automation are the drivers for change
- These are common arguments in a classic IT delivery organisation, devops helps to bridge these gaps Explain why tools can bridge the gaps
- Slide is self explanatory but talk about the concept of shift left and how it relates to the IBM model (£1 in requirements : £100 in prod) Make the points about testing being quality control rather the quality assurance and how shift left moves to real quality assurance Explain again how tools bridge the gaps in process
- Tools sit across your methodology they are you control panel Discuss each area in more detail Discuss the use of the tools in more detail and where they fitted into Specsavers
- Talk about the real world benefits of TMMi and where it added most value outside of testing services Shift left again Measurements we would expect are not always in place or understood give example would a developer write a negative test?
- Quote by Peter Drucker explain what it meant to me
- But I couldn’t resist these!!!!!
