3lbs (2% of body weight) • 73% water • 60% of the dry weight is fat • Contains 86 billion neurons • Gets 20% of our blood/oxygen • 100,000 miles of blood vessels • 2% dehydration affects cognitive skills • Every minute one litre of blood flows through the brain • Humans have the largest brains proportional to body weight
with each other using electrical and chemical signals • Neurons link via axons • Producing a neural circuit • Different circuits perform different tasks • A neuron can transmit 1,000 nerve impulses per second • There are 10,000 specific types of neurons in the brain • Brain information travels at 268 mph
moving away from, and reframing once-useful mind-sets and acquired behaviours that were effective in the past, but now limit our success. It’s not forgetting or discarding knowledge or experience; it’s the conscious act of letting go of outdated information and actively gathering and taking in new information to inform effective decision making and action.” Barry O’Reilly
and prevent them from learning • Learning can change our brains in terms of function, connectivity and structure • Our brain shapes our learning but learning shapes our brain • Research has shown that simply knowing about brain plasticity can improve learners’ ability to learn
drivers because this region of the brain is specialized in acquiring and using complex spatial information in order to navigate efficiently. Taxi drivers have to navigate around London whereas bus drivers follow a limited set of routes. Hippocampus (entorhinal cortex)

with automatic unconscious processing (away from the front of the brain). Practice helps consolidate freshly-learnt mental processes until we can do them almost without thinking, so reducing the burden on working memory.

in long term memory in the form of schemas • A schema organises elements of information according to how they will be used • Skilled performance is developed through combining complex schemas
organisational agility. Limit the size of services/products to the cognitive load that the team can handle. Each service must be fully owned by a team with sufficient cognitive capacity to build and operate it.”

us from the potentially harmful effects of change. Humans are wired to resist change and we are working against our biology at every turn. It’s well documented that every year 50 to 70 percent of all change initiatives fail.” Britt Andreatta
experience, avoiding something from occurring. Fear causes subcortical activity in the amygdala which in turn activates the working memory network in the frontal lobe (where conscious attention happens) which makes it harder to learn as the anxiety is a distraction.

training that failure is a learning opportunity Continuous integration breaks builds and prevents defects from going downstream Fail walls like Spotify to make failure visible and addressable Deployment automation drives consistency/auditability and allows instant redeploy of last known good state Awards for failure like Etsy, LEGO and Proctor & Gamble Limited blast radius approaches: feature toggles, canary, blue/green, microservices Ensuring shared accountabilities and goals across and between teams Integrating the service desk to the product backlog Making experimentation time explicit (i.e. writing it into the product backlog) Application performance management delivers early warning preempting failure Using collaboration platforms to share learning and best practice ChatOps to swarm problems and incidents Writing actions from retrospectives as experiments and making time to ensure follow up Chaos engineering teaches failure as a habit – use the Simian army
to a reward. Anticipation creates an uptake of neuromodulators from deep within the brain that influence the way our frontal cortex is operating so that our brain can become more focused on the source of the excitement and improves memory of the experience Hippocampus (entorhinal cortex) Left inferior parietal lobule Premotor Cortex Motor Cortex Superior parietal lobule Frontal Lobe Amygdala Hypothalamus
– the relative importance to others. Certainty – the ability to predict future. Autonomy – the sense of control over events. Relatedness – the sense of safety with others. Fairness – the perception of fair exchanges.
