Faster, Cheaper, Better -- Perhaps you can get all three but I have found that when dealing with my customers I need to have a tool to communicate the cost of a feature. Yes you can bring in a superstar at a higher rate for a shorter period of time but there are costs associated with recruiting and placing the superstar. Also, when it comes down to faster or cheaper -- most project leads do not address the necessary rework and remediation to be done when going for faster or cheaper.

Project architects and leads need to address the cost of each feature so the customer can at least be aware of the cost they are incurring with each additional feature (bells and whistles). When the cost of additional features exceeds the costs of all the previous features, customers tend to reject the new features.
