Talk given on 14th October at Agile Yorkshire An increasing number of organisations - including many that follow Agile practices - have begun to adopt DevOps as a set of guidelines to help improve the speed and quality of software delivery. However, many of these organisations have created a new 'DevOps team' in order to tackle unfamiliar challenges such as infrastructure automation and automated deployments. Although a dedicated team for infrastructure-as-code can be a useful intermediate step towards greater Dev and Ops collaboration, a long-running 'DevOps team' risks becoming another silo, separating Dev and Ops on a potentially permanent basis. I will share my experiences of working with a variety of large organisations in many different sectors, helping them to adopt a DevOps approach whilst avoiding another team silo. We will see examples of activities, approaches, and ideas that have helped organisations to avoid a DevOps team silo, including: - DevOps Topologies: "Venn diagrams for great benefit DevOps strategy" - techniques for choosing tools (without fixating on features) - new flow exercises based on the Ball Point game - recruitment brainstorming - Empathy Snap, a new retrospective exercise well suited to DevOps This session will provide 'food for thought' when adopting and evolving DevOps within your own organisation.

30. 1. Financial data
Goal: shorter Lead Time
No ‘DevOps’ team 
Challenge: define the purpose of the new team(s)
(‘naming things is hard’)

Are the main challenges technical?
(Clue: probably not)

70. How to choose tools for DevOps
Value collaboration aspects
Avoid a learning mountain: evolve tooling
Avoid Production-only tools
Consider Conway’s Law
(this list is incomplete!)

72. Recruitment

73. Don’t hire ‘DevOps’

75. Recruitment suggestions
Site Reliability Engineers (SRE)
Web Operations (‘WebOps’?)
SysAdmin+ Git + TDD (?)

76. Recruitment suggestions
Diplomacy
Facilitating
Evangelising
Mentor
Deep specialism in SAN fabrics

77. Yes, we still need operations
Metrics
Layer 2 / 3 subtleties
Rapid diagnosis
Fault heuristics
Incident response experience
‘Battle-scars’

78. Recruiting for DevOps
Don’t hire ‘DevOps’
Don’t advertise for ‘DevOps Engineer’
Use SRE / WebOps/ TDD
Don’t forget Operations skills!

85. Team topologies
There is no ‘right’ topology
Many ‘wrong’ topologies for one organisation
Consider skills, core business, SLAs, …
Evolve the topology over time (2 years)
Communicate the purpose

86. Flow exercises
Adapt to include IT Ops people
Learning through physical interaction
Model and measure flow
Flow exercises help choose a team topology

87. Other things
Consider the collaboration value in all tools
Shared tools for shared responsibilities
Don’t hire ‘DevOps’
Encourage empathy

88. We did not really mention:
Funding: CapExvs OpEx
Bonuses & financial rewards / penalties
Building a culture
Conway’s Law
…
