quote from 'The Lean Startup'

From Eric Ries's well-loved book, "The Lean Startup". I added some emphasis.

I often see this in my consulting practice. I’ve been called in many times to help a startup that feels that its engineering team “isn’t working hard enough.” When I meet with those teams, there are always improvements to be made and I recommend them, but invariably the real problem is not a lack of development talent, energy, or effort. Cycle after cycle, the team is working hard, but the business is not seeing results. Managers trained in a traditional model draw the logical conclusion: our team is not working hard, not working effectively, or not working efficiently. Thus the downward cycle begins: the product development team valiantly tries to build a product according to the specifications it is receiving from the creative or business leadership. When good results are not forthcoming, business leaders assume that any discrepancy between what was planned and what was built is the cause and try to specify the next iteration in greater detail. As the specifications get more detailed, the planning process slows down, batch size increases, and feedback is delayed. If a board of directors or CFO is involved as a stakeholder, it doesn’t take long for personnel changes to follow.
