HW: Ch. 1 problems and exercises 1. Why is it important to use systems analysis and design methodologies when building a system? Why not just build the system in whatever way appears to be “quick and easy”? What value is provided by using an “engineering” approach? 2. How might prototyping be used as part of the SDLC? 3. Compare Figures 1-2 and 1-3. What similarities and differences do you see? 4. Compare Figures 1-2 and 1-4. Can you match steps in Figure 1-4 with phases in Figure 1-2? How might you explain the differences between the two figures? 5. Compare Figures 1-2 and 1-12. How do they differ? How are they similar? Explain how Figure 1-12 conveys the idea of speed in development. 6. Compare Figures 1-2 and 1-9. How does…show more content…
Information systems can be analyzed in this circular motion. For example, if you have a system that is fully developed and goes on the market, but does not really work as intended, you can go back to the cycle, see what went wrong, fix the problem so it does not happen again, put the system back on the market, and learn from it. 3. Figure 1-2 and figure 1-3 are similar because they both show how the cycle should be followed when analyzing a system. Figure 1-2 is different from figure 1-3 because the life cycle appears to be in order, but it is not. The specific steps and their sequence are meant to be used for a project that is consistent with management approaches. 4. Figures 1-2 and 1-4 are similar in fact that even figure 1-2 seems simpler than figure 1-4 they are actually still use in the same approach and that when implementing the life cycle every company takes the same approach. In Figure 1-2, starts with planning and the cycle ends with implementation. With figure 1-4, this figure starts with and initiation and ends with a disposition. This plan is mostly used by medium to large corporations. 5. Figure 1-2 and figure 1-12 are similar because they both use the same type of prototype or model. However figure 1-2 focuses specifically on how the cycle should be followed when analyzing a system. And figure 1-12 focuses specifically
