In essay format,
a. Compare 3 estimating techniques: Analogous, Bottom-up and Parametric. Explain the circumstances which determine the method you should use each type as your primary method.
Provide an explanation of why you should use each type as your primary method based on the circumstances in section below.
b. There are two common ways to estimate cost and duration using the 3-point method. The first is the triangular distribution where the estimate is based on the average of the optimistic (O), most likely (M), and pessimistic (P) estimates. Mathematically, Your estimate = (O+M+P)/3. The second way is based on the Beta distribution that puts more weight on the most likely. Mathematically, your beta estimate = (O+4M+P)/6. Using the following, calculate the two estimates of duration: O=4; M=6; P=11. Explain the difference in the answers. How would you decide which method to use?
Each paragraph should have
(1) Leading headers to show critical thinking.
(2) Have enough detail information to support your answers the with each estimating technique.
(3) Use credible references cited in APA format.
