Business System Analysis

Chapter 1 Problems/Exercises1.)Why is it important to engage schemes analysis and design methodologies when structure a system? Why not just build the system in whatever way seems to be quick and easy? What survey is provided by using an engineering turn up?Its important to use systems analysis and design methodologies when building a system because it look into the select of the system being built, it is also tested and you are following an withdraw process that is very structural. If you build a system in whatever way seems to be quick and easy, it can result in a poorly developed system, yes it can be easier and cheaper but in the languish run it can require extra work to maintain and much money to maintain it. The value that is provided by using an engineering approach is well designed, precise and systematic. 8.) How might prototyping be used as fate of the SDLC?Prototyping is part of the feasibility analysis phase of SDLC. A simulated standard of the target system is created which gives the initial fee of the target system. This also helps in pre-analyzing the behavior of the target system.Chapter 23.) In the section on choosing off-the-rack package, eight criteria are proposed for evaluating pick packages. Suppose the choice is between alternative r issueine software developers rather than prewritten packages. What criteria would be appropriate to select and liken among competing gambolders for custom development of an application? Define each of these criteria.The criteria for evaluating alternative packages from custom software developers would be cost, functionality, and response time. As with custom software, you know from your bid that vendor support, viability of vender,flexibility, documentation and ease of installation is taken care of, as the vendor will install the system, supply appropriate documentation, will ensure flexibility of software (if in the bid) and will offer support for its give birth software that it wrote for the company.As far as viability of vender, I would hope that virtuallyone chequered out the company before giving a bid. When trying to get back which software a developer is going to go with we would want to follow slightly much the same criteria they we followed when going with an off-the-rack software. Regardless if its an off-the-shelf or custom made I would still want the software to have the same features. Will the software developer have some figure of warranty will they stand behind their product? Will it be easily installed? Cost, usefulness and will the developing company offer some sort of documentation.Off the shelf software, also known as shrink-wrapped or put up software, refers to standard (not custom) software applications. When you take off the shelf software out of the package, you automatically agree to the terms and conditions of the software license and agreement. The most earthy criteria for choosing off the shell software are the following Cost, Funct ionality, Vendor Support, Flexibility, Documentation, Response, Time, and relievo of Installation.4. How might the project team recommending an ERP design outline justify its testimonial as compared with other types of design strategies?By using a strategy through cost saving due to facilitated reuse/raw materials arsenal and by innovating, integrating and transforming their design processes.
