Q1 Work problem 10.8 (Software Engineering Economics) Ans Since N max = S-P+M/2M a) Increase processor speed S If we increase the processor speed S then N max also increases because keeping all parameters constant here N max is directly proportional to S thus if S increases N max also increases. Eg when S is 1100 Nmax is coming out to be 6.125 and so on ,keeping P=200 and M =80 here. s Nmax 1100 6.125 1200 6.75 b) Increase processor overhead P On increasing P ,N max decreases. Eg keeping S =1000,M=80 and P=200 we have Nmax= 5.5 but P Nmax 300 4.875 400 4.25 500 3.625 c) Decrease multiprocessor overhead M On decreasing M ,Nmax increases, keeping S=1000,P=200 ,eg M Nmax 60 7.16 40 10.5 20 20.5 d) Increase required operations/transaction T Here this will have no effect on Nmax because Nmax doesnot depends on T.
Q2.  Work problem 10.12 in Software Engineering Economics. Assume program size is in KSLOC. Use COCOMO  II with Nominal effort multipliers and the following scale factor ratings: PREC = FLEX = TEAM = Very High; RESL  = PMAT = Low Using COCOMO II the following graph represents software development cost.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
