"Everyone is protecting their local revenue, their regional goals... and then COVID hit. Suddenly, 2 million customers abroad that need to be repatriated"
-
"The board stated, we cannot let this opportunity go to waste: we must prepare for a prolonged period of lower revenue. We had to move fast. Use this crisis to consolidate the business."
- we decided to .... focus on flow
- textbook rules we broke:
- "take a small application to the cloud and learn"
- We took 6$billion Selling Platform
- 130 staff trained
- "lift and shift to the cloud"
- we build new
- "Proof concept of agile initiatives, then scale"
- we transformed globally
- "take a small application to the cloud and learn"
-

"3 VPs in a room to approve changes — can you imagine how time-consuming and boring this could be?"
Ben Conrad (UK’s Tax Department (HMRC)), Matt Hyatt https://sched.co/i53K
- the lockdown had a 20% impact on UK the economy
- biggest reset in 300years
- HMRC platform:
- 1200 Microservices
- 70 teams - 2100 people
- 8 locations
- 100 deployments / day
- scala, python, github, jenkins, AWS, mongoDB
- opinionated platform "we have strong opinions"
- basic set of rules ie
- Must use scala, mongodb for persistence...
- "Thou shalt not get AWS Creds"
- Security is one reason. We provide the platform, developers don't need direct access to an AWS. Billing we handle. Metrics we direct to grafana etc.
- I'm not saying there isn't a trade off, but we abstract that away so scala developers don't need to know anything about the infrastructure.
- opinions to prevent waste
-
"Load testing... then broke our logging pipeline."
- worked with more than 100 logins per second
- basic set of rules ie

- people need sleep
- be careful of setting unhelpful precedents even when saving the world

It's hard to look at a broken system, when you can't change it
Flow needs to be important to leaders ... in words and deeds
break down silos
"no" can't be the final word.
Think about the system, not the department

what works
- shared language (team topologies)
- Wardley maps
- Team API #learning/🔍checkagain
Tricky
- assessing teams cognitive load
- compliance as code
Antipatterns:

"Frameworks are extracted, not built"
-
Github forked rails 2.3 in 2009
-
they changed it and never upgraded - it was just fine
-
... but it wasn't fine
- Hiring was hard
- security backports
- development was painful
- dependencies
-
upgrading the application took months (backports)
-
in 2018 - reaching 4.2 and going to original 5.0
-
refusing to upgrade is more expensive and more risky than taking the time to upgrade
-
you can not quantify the cost of not upgrading
-
When upgrading you should
- Build a team
- reward the work (not only features)
- take time to make a plan
- fix deprecation warnings early
- plan for the future
-
don't do: - you will regret it
- don't fork a framework (or library)
- don't fall behind on security releases
- don't deprioritize upgrades (this is for the leadership)
-
benefits
- access to improved APIs
- security features
- performance improvements
- a chance to contribute upstream
- they had a bonus program - 100¼ for everyone who got a certification on any agile/devops topic
- lead to 300 certifications
- 900 members in "Community of practice"
- special training for business leaders

-
you need to include flow-metrics in your KRs
-
what goes wrong:
- use only business and financial metrics in KRs
- use only team or proxy metrics
- conflate OKRs with roadmaps
- OKRs that micromanage teams & deliverables
- do not account for flow
- ignore capacity
-
good:
- make b goals and prioritization clear
- measure flow of value
- support learning and improvement
-
organizational OKRs
- should create conditions and structures to enable flow
-
.... there is an example about tech-debt
-
progressive delivery is the next step after Continuous delivery where new versions are deployed to a subset of users and are evaluated in term s of correctness and performance before rolling them to the totality of users or rolling it back when it fails to meet key metrics.
- decouple deploy from release
- blue/green release
- canary release (container based)
- feature flags
- Feature flags and data, integrated
- learn during the process
