If you have the time (and it is quite long) there are some real gems in “No Plan, No Capital, No Model…No Problem”, a Churchill Club panel session hosted by Guy Kawasaki. The five panellists, Marcus Kazmierczak, Markus Frind , James Hong, Dave Lu and Karen Northup have all set up companies with little or no cash and no backing from venture capital.
What particularly interested me in terms of my advocacy of purposive drift was that each of the panellists adamantly argued that had they followed a business plan they would have missed opportunities that arose and lacked the flexibility of mind to deal wit rapidly changing circumstances.
Do take a look at the whole thing here.
