## What is Function Point estimation?

Advertisements. A Function Point (FP) is a unit of measurement to express the amount of business functionality, an information system (as a product) provides to a user. FPs measure software size. They are widely accepted as an industry standard for functional sizing.

## What are cost estimating relationships?

Cost Estimating Relationship Definition. As the name implies, a cost estimating relationship (CER) is a technique used to estimate a particular cost or price by using an established relationship with an independent variable.

## What is the best technique to use when estimating project costs?

The best technique for cost estimating is to use a Bottom Up estimate.

## Which method of cost estimation is most detailed?

quantity survey methodThe quantity survey method is the most detailed method. This requires you to break down all of the components of a building and estimate the cost of the material and installation separately. This is a quick method to give you a ballpark of your construction costs.

## What are the different types of estimation techniques?
