Found this interesting thread on Quora. Every entrepreneur should read it. Took me about an hour to get through it all.

Here’s an exerpt

The best way for me to clarify my point is to say there are A, B, & C players.  A startup with C players in any function has issues and should get right of that person.

The question here is where do you have to have A players and where can get by with B players that are good, committed, deliver but are not rockstars?

In the current world of technology/IT, the A-skill is less of a requirement on the engineering side, compared to 10-15years ago.  And the reason is simple: the tough technical problems have been solved, abstracted away, or there are incredibly cheap workarounds that exist.

+ Salesforce could have gotten away with a B engineer, but Benioff’s A sales skills were key.
+ Groupon could have gotten away with a B engineer, but Mason’s A insights were key

In some cases, the product/customer/ channel/community side strength is some skill (Jobs, Ellison), sometimes its luck coupled with shrewdness & grit (Gates, Zuck, Mason).

Either way, these companies didn’t succeed because their first & key product crossed some technical barrier, but because the business picked up momentum that could dwarf any marginal technical bug that existed.
