Sample text
Does it matter that there are differences? 6 For each of the applications described in Appendix A assess the importance of the various goals identified in this chapter. For each application, rank the goals in order. 7 What would you expect the relative costs of hardware and software development to be in each of the cases above? 8 How do you personally feel about software maintenance? Would you enjoy doing it? 9 Think of an example of a program in which the aims of minimizing run time and memory occupancy are mutually contradictory.
Costs and benefits are usually estimated over a five year period. This means that the initial start-up costs are spread over the expected useful life of the system. Five years is the typical lifetime of a computer-based system. Beyond this time, changes in technology as well as changes in requirements make predictions uncertain. Many evaluation criteria are common to all computer systems – and indeed to all products designed for some useful purpose. Thus motor cars, buildings and televisions need to be reliable, robust, easy to maintain, easy to upgrade.
1 Write down a list of all of the different items of software that you know about, then categorize them within types. 2 What are your own personal goals when you develop a piece of software? Why? Do you need to re-examine these? 3 Is software expensive? What criteria did you use in arriving at your conclusion? 4 Is programming/software development easy? Justify your answer. 5 The evidence suggests that there are enormous differences between programmers in terms of productivity. Why do you think this is?
