Given below are the formulae for effort estimation for BASICVersion’s modes.

Organic:

E = 3.2 x (size in KLOC)1.05

Semi Detached:

E = 3.0 x (size in KLOC)1.12

Embedded :

E = 2.8 x(size in KLOC)1.20

Given below are the formulae to calculate the Time required forproject schedule.

Organic:

T = 2.5 x (Effort).38

Semi Detached:

T = 2.5 x (Effort).35

Embedded :

T = 2.5 x( Effort).32

Formula to calculate the number of people is...

Total number of people needed= Effort / Total time todevelop

Given below are the formulae for effort estimation forIntermediate Version’s modes.

Organic:

E =EAF*3.2*(KLOC)1.05

Semi Detached:

E = EAF*3.0 x (KLOC)1.12

Embedded :

E = EAF*2.8 x( KLOC)1.20

Given below are the formulae to calculate the Time required forproject schedule.

Organic:

T = 2.5 x (Effort).38

Semi Detached:

T = 2.5 x (Effort).35

Embedded :

T = 2.5 x( Effort).32

Assignment Questions

Q#1: Your team is asked to develop criticalsoftware of health insurance system, as the project is complex andsensitive related to the Insurance of health so there is no chanceof error. If the size of the project is 33200LOC then calculate the“Effort” in person month, and“Time” required to develop (Schedule)the Software in months, with the number of people required tocomplete the project using “Organic DevelopmentMode”.                            [15]

Q#2: A project estimated size is15000LOC and it is an accounting SW. Calculate the“Effort” in person month and“Time” to develop it, with the numberof people required to complete the project using“Intermediate Version’sMode”.    [15]

Organic:

E = 3.2 x (size in KLOC)1.05

Semi Detached:

E = 3.0 x (size in KLOC)1.12

Embedded :

E = 2.8 x(size in KLOC)1.20

Explanation / Answer

instead of putting 33200 i think we should put 33.2 as KLOCdirectly,and by doing this the answer is changed totally,plzexplain and similarly in Q2 it should be 15 instead of15000????
