'Chapter 1 Problems/Exercises1.)Why is it important to use carcasss summary and design methodologies when designing a brass? Why not just realize the dodging in some(prenominal) course seems to be â€Å"quick and easy?” What prize is provided by using an â€Å"engineering” come up?It’s important to use systems epitome and design methodologies when building a system because it ensure the quality of the system existence built, it is besides tested and you are pastime an reserve process that is very structural. If you build a system in whatever way seems to be quick and easy, it piece of tail result in a severely developed system, yes it a visite be easier and cheaper scarcely in the long run it can require extra work to remark and more money to maintain it. The time value that is provided by using an engineering fire is well designed, precise and systematic. 8.) How might prototyping be used as fragmentise of the SDLC?Prototyping is part of t he feasibility analysis phase of SDLC. A simulated prototype of the target system is created which gives the initial fee of the target system. This as well helps in pre-analyzing the behavior of the target system.Chapter 2:3.) In the section on choosing off-key-the-rack software package system, eight criteria are proposed for evaluating alternative packages. view the choice is between alternative usage software developers rather than prewritten packages. What criteria would be clutch to select and compare among competing bidders for custom knowledge of an application? Define each of these criteria.The criteria for evaluating alternative packages from custom software developers would be: cost, functionality, and rejoinder time. As with custom software, you know from your bid that vender run on, viability of vender, flexibility, documentation and ease of generalisation is taken care of, as the vendor will install the system, supply appropriate documentation, will en sure flexibility of software (if in the bid) and will vortex support for its own software that it wrote for the company.As far as viability of vender, I would hope that someone analyse out the company before natural endowment a bid. When trying to decide which software a developer is going to go with we would take to follow pretty much the similar criteria they we followed when going with an off-the-shelf software. Regardless if it’s an off-the-shelf or custom do I would still want the software to have the same features. Will the software developer have some sort of stock-purchase warrant; will they stand behind their increase? Will it be easily installed? Cost, usefulness and will the developing company offer some sort of documentation.Off the shelf software, also known as â€Å"shrink-wrapped” or â€Å" transcribed” software, refers to standard (not custom) software applications. When you take off the shelf software out of the package, you mechanicall y agree to the terms and conditions of the software endorse and agreement. The most common criteria for choosing off the racing shell software are the following: Cost, Functionality, vender Support, Flexibility, Documentation, Response, Time, and Ease of Installation.4. How might the project aggroup recommending an ERP design strategy justify its testimonial as compared with other types of design strategies?By using a strategy through cost saving due to facilitated apply/raw materials inventory and by innovating, desegregation and transforming their design processes.\r\n'
