Statistical Software Quality Assurance is a technique that measures the quality in a quantitative fashion. It implies that information about defects is collected and categorized and an attempt is made to trace each defect to underlying cause.

 

Let us assume that information about defects is collected for one year and categorized as follows:

 

 

    1. Incomplete or erroneous specifications (IES)
    2. Misinterpretation of customer communication (MCC)
    3. Intentional deviation from specifications (IDS)
    4. Violation of programming standards (VPS)
    5. Error in data representation (EDR)
    6. Inconsistent component interface (ICI)
    7. Error in digital logic (EDL)
    8. Incomplete or erroneous testing (IET)
    9. Inaccurate or incomplete documentation (IID)
    10. Error in programming language translation of design (PLT)
    11. Ambiguous or inconsistent HCI (HCI)
    12. Miscellaneous (MIS)

 

The following data is collected for these categories

 

 

Error Category Serious Moderate Minor Sub Total
IES 40 70 85  
MCC 20 50 85  
IDS 25 5 10  
VPS 0 30 50  
EDR 40 68 36  
ICI 9 18 31  
EDL 14 12 19  
IET 12 20 48  
IID 2 20 25  
PLT 20 55 40  
HCI 3 17 8  
MIS 0 40 64  
         
Total        

 

 

  1. You need to complete the table
  2. Identify FIVE categories on the basis of vital errors
  3. Identify FIVE categories on the basis of vital if only serious errors are considered.

CS605 Software Engineering II Assignment 1 Spring 2011 Idea Solution

You are working on a project and you have to decide which language you will select for its development. Let us consider that the same functionality is implemented in Assembly Language and in C++ language. Lines of code in Assembly language are 4 times as compared to C++ language because coding in Assembly is much more difficult and time consuming as compared to C++. The requirements, design anddocumentation activity in person month are the same in both the languages but integration & testing and Management activity is thrice in assembly language.

a. You have to fill out the above table according to the given scenario and calculatetotal effort, total cost, and lines per person month. (10 Marks)

b. Why coding in Assembly language appears to be more cost effective than C++ while in reality it is not. This is a paradox! Explain. (10 Marks)
