Comparative Analysis of Top-Down and Bottom-Up Estimating Techniques
Concluding Remarks

From the Paper:

"The top-down technique revolves around analyzing the value of the project from the business standpoint. It looks at data from the balance sheet and transforms it into information relevant for the project team. The information can generically be retrieved by any party involved in the project, but most commonly this task belongs to those who possess sufficient experience, marketing information, benchmarking capabilities or any other extra-project characteristics. The estimations are seldom based on concrete and verifiable facts. The bottom-up technique on the other hand analyzes the estimates of the project, retrieved from analyses of the already known facts. The most common fact estimation refers to the amount of work the team will have to put in for the completion of the project."
