The Tortoise and the Hare
Our half of the problem certainly calls for 100% of our attention; makes me remember this quote:
"Software is not limited by physics, like buildings are. It is limited by imagination, by design, by organization. In short, it is limited by properties of people, not by properties of the world. 'We have met the enemy, and he is us' " -Ralph Johnson
Lack of soft skills, like effective negotiation, the inability to say ‘no’, also adds up to that half.
This other quote comes to mind:
"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." -C.A.R. Hoare
Improve our industry! -> Improve your practice!
