MITs Earl Miller, People cant do [multitasking] very well, and when they say they can, theyre deluding themselves. And it turns out the brain is very good at this deluding business.

Asking the brain to shift attention from one activity to another causes the prefrontal cortex and striatum to burn up oxygenated glucose, the same fuel they need to stay on task.https://www.theguardian.com/science/2015/jan/18/modern-world-bad-for-brain-daniel-j-levitin-organized-mind-information-overload

Too much variabilityKnowledge work is not deterministic

ValueGlidecreating better outcomes@valueglide #bizagility

Knowledge work is not deterministic because the nature of our work but Our ways of working impact the long tailHow much wip impacts completion timeHow we cordinate work across teamsHow we schedule work across teams

WIP LimitsEssential to create pullMinimise mental overloadCreate focusPride of workmanship

Understand FlowWhere do you spend your time? How much time is due to multi-tasking?Where do you wait?

* Zsolt Fabok, Lean Agile Scotland, Sep 2012, Lean Kanban France, Oct 2012** Hakan Forss, Lean Kanban France, Oct 2013% Flow Efficiency = (Work Time/ Lead time) * 100

ValueGlidecreating better outcomes@valueglide #bizagility

Completion Time = 114 Days made up of 41 days waitingThis is only between different functions Does not include the wait time within a function% Flow Efficiency = (Work Time/ Lead time) * 100=(73/114)*100 = 64%
