Good case study / anecdote about how a company responds to competitive pressures in the agile vs. waterfall world.

From the article:

Two years ago, in response to emerging customer needs and a surge of new entries into the network monitoring market, Ipswitch realized it had to pick up the pace of its product development strategy. Although the company's software had been widely regarded as among the best and easiest to use, the game had changed. Overseas companies had started to become serious price competitors. And a number of domestic startup firms, armed with marketing tactics fortified by strong venture funding, had also aggressively entered its space. As a result, unless the company could deliver its products to new and frequently inexperienced customers in ways that would work right the first time, Ipswitch's managers knew their market edge risked being lost for good.
