“However, in the early phase of software development, it’s possible to shake free of these restrictions, especially when teams are small and the hunt for ideas is still on. This was the scenario when Richard joined us at Apple. We were still looking for an organizing concept to kick-start our web browser effort, and Richard showed us how. Not only that, he proved that a 10x productivity gap is a conservative upper limit on the possible in early stage software. Indeed, Richard did more to move our project ahead in two person-days of work than Don and I had done in the preceding twelve person-weeks. That’s more like a 30x gap.”
