Conventional Wisdom

Faster, Better, and Cheaper?

Organizational culture was one of the strongest predictors of both IT performance and the overall performance of the

organization

Devops is about Humans

Devops is a set of practices and patterns that turn human

capital into high performance organizational capital.

Often skips CAB. What CAB reviews is often not what built

All manual setup. 1 person really knows how. Low data quality.

Manual process with lots of back and forth.

Many tickets with mismatched priorities

Mostly manual testing

• Make the work visibile for all • Manage flow and eliminate waste • Build alignment and consensus across team boundaries • Empower teams to find and fix what is getting in the way

• Small Batch • Reduce Work in Process (WIP) • 1x1 Flow • Reduce Bottlenecks (TOC) • Optimize Globally

Let’s talk Kata

I fear not the man who has practiced 10,000 kicks

once, but I fear the man who has practiced one

kick 10,000 times

- Bruce Lee

Toyota is not a story about techniques. It’s an organization defined primarily by the unique behavior routines it continually

teaches to all it’s members.

Mike Rother (Page 262-263)

I have no idea how to answer

that question. It would literally

never occur to me not to do it!

We are what we repeatedly do. Excellence, then, is not

an act, but a habit.

Safety Culture

Views on Human Error

▪ Views on Human Error

▪ The old view of human error (First Story)

▪ Human error is the cause of accidents ▪ To explain failure,you must seek failure ▪ You must find people’s: inaccurate assessments,wrong decisions, bad judgments

▪ Views on Human Error

▪ The new view of human error (Second Story)

▪ Human error is a symptom of trouble deeper inside a system ▪ To explain failure, do not try to find where people went wrong ▪ Instead, find how people’s assessments and actions made sense at the time, given the circumstances that surrounded them

▪ Bad Apple Theory - Throw away the bad apples

▪ Complex systems are basically safe, they need to be protected from unreliable people (bad apples) ▪ Human errors cause accidents: humans are the dominant contributor to more than two thirds of mishaps ▪ Errors occur because of human loss of situation awareness, complacency, negligence ▪ Errors are introduced to the system only through the inherent unreliability of people.

What can go wrong usually goes right, but then we draw the wrong conclusion.

Murphy’s Law is Wrong! Sidney Dekker The Field Guide to Human Error

Your organization must continually affirm that individuals are NEVER the ‘root cause’ of outages.

▪ Hindsight bias: ▪ knew-it-all-along, to see the event as having been predictable, counterfactuals

▪ Outcome bias: ▪ evaluating the quality of a decision when the outcome of that decision is already known

▪ Availability bias: ▪ preference by decision makers to information and events that are more recent

▪ Fundamental attribution error: ▪ explain behavior in terms of internal disposition, such as personality traits, abilities, motives, etc. as opposed to external situational factors

▪ Just Culture at Etsy (John Allspaw)

▪ Encourage learning by having these blameless Post-Mortems on outages and accidents

▪ Understand how an accidents happen, in order to better equip ourselves from it happening in the future

▪ Gather details from multiple perspectives on failures, and we don’t punish people for making mistakes

▪ Enable and encourage people who do make mistakes to be the experts on educating the rest of the organization how not to make them in the future

▪ Just Culture at Etsy (John Allspaw)

▪ Accept that there is always a discretionary space where humans can decide to make actions or not, and that the judgement of those decisions lie in hindsight

▪ Accept that the Hindsight Bias will continue to cloud our assessment of past events, and work hard to eliminate it

▪ Accept that the Fundamental Attribution Error is also difficult to escape, so we focus on the environment and circumstances people are working in when investigating accidents

"In dynamic fault management, intervention precedes or is interwoven with diagnosis"

- Woods (1994)

Learning Organization

That’s how it’s always been done

around here!

You are either building a learning organization… or you will be losing to someone who is

Ladder of Inference Chris Argyris

• Action • Beliefs • Conclusions • Assumptions • Meanings • Select • Observe

Ladder of Inference

▪ Can create bad judgement ▪ Our assumptions can lead us to bad conclusions ▪ Question your assumptions and conclusions ▪ Seek contrary data ▪ Make your assumptions visible to others ▪ Invite others to test your assumptions and conclusions ▪ Inquire other peoples assumptions and conclusions ▪ Move down the ladder instead of up

Ladder of Inference - Bad Judgement ▪ Observe - Notice people in the first row ▪ Select - Person in front row keep looking at their phone ▪ Meaning - Not listening to my presentation ▪ Assumption - He is not interested ▪ Conclusion - Doesn’t like my new idea ▪ Beliefs - Their team always blocks new ideas ▪ Action - I send a nasty email to their boss

Ladder of Inference - Alternative Assumption ▪ Observe - I notice people in the first row ▪ Select - Person in the front row keep looking at their phone ▪ Meaning - Not listening to my presentation ▪ Assumption - Try and engage with a question (safely) ▪ Conclusion - Might find out that they are late for another meeting and they really don’t want to miss this one… so they sent an email noticing the next meeting team that they will be late…. ▪ Beliefs - They are very excited about this new idea ▪ Action - Both teams setup another meeting to engage.
