Answer 5

E=a​×(KLOC)^b​
​

Question 6

For the COCOMO Time of development (in months), what is the formula?

Answer 6

D(TDEV)=c​×E^d

Question 7

For the COCOMO Number of people, what is the formula?

Answer 7

N=E/D

Question 8

What is the methods for calculating the unadjusted weight of one use case point?

Answer 8

Calculate the number of transactions
Based on the number of transactions, classify them into their respective weight classes
(<=3 Transactions:5, 4-7 Transactions:10, >7 Transactions: 15)

Question 9

How to calculate all the use case point weights?

Answer 9

Multiply weight with number of UCP

Question 10

What are the 3 actors’ classification of assigning weight?

Answer 10

Simple (1):Components interacting
through well defined API
Average (2):External system that must
interact with the system
using standard
communication protocols
(e.g. SOAP, TCP/IP, FTP,
HTTP, database)
Complex (3):Human actor using a GUI
application interface or
text-based interface

Question 11

After calculating your Use cases, Actors, NFRs and Development Environment, How to calculate overall UCP?

Answer 11

UCP = (Use cases+Actors) * TCF * EF

Answer 13

d. To illustrate the flow of the interactions between users and the system

Question 14

What is the difference between an include relationship and an extend relationship in a use case diagram?
