Alternate view point - driving projects to a specific deadline allows the other departments in the company to coordinate marketing, packaging, and selling the product. These people don't sit on their hands patiently waiting for engineers to finish building, their work can take many months just as the development does, and sometimes also involves making tradeoffs to deliver on time. No company wants to wait another year after development is finished before they start earning money for it.
