Task 2 The advantages of choosing web-based architecture for the company’s system are that the application is cost effective in terms of development. The users will be able to access the system through a similar environment. The application will be developed for one operating system. One will not have the need to develop and then test it on various configurations and systems version. This tends to make troubleshooting and development very much easy especially when the application used testing, front-end, and troubleshooting. The architecture is also easy to access anywhere and anytime via a personal computer provided there is internet connection, putting users of when to access the application. The application is also easy to customize. This make easy updating in terms of feel and look of the application by customizing the information presentation to different groups of users. Consequently, the application is more secure. This is because the application is deployed on dedicated ser vers, which are maintained and monitored by service administrators who are experienced. In summary, the application is easy to develop, useful to users, easy to install and maintain, and it is easy to grow as the company grows.

Purchasing software packages need to be part of the strategies therefore to cater for growth, the company needs to include the interface information that is needed between the system and package the company is developing. The company needs to develop and use the CASE design tool where the company will be able to print design diagram and other document from the CASE design tools in the system. Task 4 The consideration for legacy systems will be an established format in the company especially in the IT management when the situation is migrating from the old to new design where the present solutions are reused. The processes, procedures, and information format needs to be developed in the field. The solutions here entail discarding the system and develop a placement system that is virtual, freezing it, and using it to be a component of a large system. The potential and consideration reuse of legacy production system is solved by using constraint structures and formal requirement especially in the early phases of design and used in the entire structuring and defining terms such as needs, musts, objectives, wishes, and goals. The four elements important in the requirement analysis include the functional requirements, internal design constraints, winning criteria, and external design constraints. Therefore, the consideration for legacy systems will be an established format in the co mpany especially in the IT management when the situation is migrating from the old to new design where the present solutions are reused.
