Dell: through speed - significant cost advantage due to low cost infrastructure. They have cheap price per component not because they buy cheaper - they buy at same price of course, but cheaper surrounding infrastructure. (1:25)
Toyota: Brought Prius from concept to market in 15 months
Google: competes on speed in software dev area
Competing on basis of speed gives : 1) a significant competitive advantage, and 2) a large barrier to entry - companies need to catch up.
Things that kill speed:
complexity
3 faces of complexity
- waste: anything that depletes resources/effort/space/money - keep it simple
- Inconsistency: uneven, unbalanced, etc - make it flawless
- overload: excessive or unreasonable burden - make it flow
Keep common infrastructure
achitecture/convention/tools
keep simplifying the code via refactoring
a dev process that anticipates change will result in software that tolerates change
Toyota's design process:
"set based design" (9:45)
They have 10 engines and pick one before production - not use one and keep making changes.
Makes decision as late as possible
Make decisions reversible whenever possible
-when change creates complexity, refactor
