Please explain how to get the Complexity Weighting table shown in the solution below? Here is the question:

The solution table is given below :

7. Omega 2 Project. Using the complexity weighting scheme shown in Table 5.2 and the following function point complexity weight table, estimate the total function point count. Assume historical data suggest five function points equ. Cone person a month and six people have been assigned to work on the project. Complexity Weight Table Number of inputs IS Rated complexity low Number of outputs 20 Rated complexity average Number of inquiries 10 Rated complexity average Number of files 30 Rated complexity average Number of interfaces 50 Rated complexity high a. What is the estimated project duration? b. If 20 people are available for the project, what is the estimated project duration? c. Ir the project must be completed in six months, how many people will be needed for the project? Using the Complexity Weight table, we get : Complexity Weighting Average High Low 15 x 2 Total 15 30 20 20 x 6 120 Elements Inputs Outputs Inquiries Files Interfaces Total 10 10 x4 = 30 30 x 8 40 240 50 50 x 15 = 750 = 1180
