Subject: Software Reliability Prediction
Message:
I have just bought the book of Reliability Toolkit:Commercial Practices Edition from RAC.I have some questions on the method of software reliability prediction in it.First,in this book,only seven programming languages'expansion ratios are provided.Does anyone could give me the expansion ratios of other programming languages(e.g.VB,VC++,DELPHI,etc.)? The second question is I found when predict a software' initial failure rate by this method,the result is only related to the host processor speed and the programming language used,but have nothing to do with the length of the code.That is,a software has 20,000 lines of code and a software has 200,000 lines of code will has the same failure rate.Does anyone could explain it? Thank you.
