Information System Analysis and Design
Introduction to Information System Analysis and Design
The aim of this report is to analyse the total expenditure and consequences of upgrading the information system of Number-One Medical Centre Ltd. This organization is a small healthcare service who wants to upgrade its tradition clerical work with advance information system, in order to expand its service and open multiple branches. All the cash transaction is done in tradition fashion, as well as the credit system. The clerks hand over write-off memos, schedule appointments and make bank depositions every day. These tasks can be performed with the involvement of modern technology and planning, at faster speed with more accuracy. The objective of this project is to investigate and documents the system requirement of the organization.
Number-One Medical Centre is a small healthcare service who aimed to expand its service in upcoming years. This can be possible only when the clerical work is updated according to the latest trend. The existing system involves human involvement. The PC-based system that the organization is using is out dated. The organization need to upgrade the information system. The first step towards optimization would be upgrading all the hardwares that the company using. The new PC-based system is faster and can efficiently perform more functions than the last system. The next step would be developing customized software according to the need of the company. All the task that were carried out by the employees, manually will now be performed through these software. Everything will connected through internet.
The database will be connected through cloud storage. Along with system upgrade, the organization also need to upgrade its employees so that they can efficiently operate the new information system. The old system of issuing write-off memos, making bank deposits and reconcile bank statements will be upgraded and carried out with the help internet banking and online data storing. All these development requires financial investment and requires a lot of time and involvement. However, the outcome will be worthy of the hard work invested. This will help the organization to expand its branch and synchronize the working of every branch through centralised information system. Apart for this, the human error will be reduce as most of the tasks will be carried out by the software.
Functional requirements lay down the proficiencies that the solution must provide to its users. It is the requirement to work out the solution. For example; to access the information on internet, internet connection and computer is used. Here, the internet connection and the computer the functional requirement (Wu & Buyya, 2015). For the Number-Medical centre, the following functional requirements are there;
- Hardware upgrade- The 8 year old PC-based system must be replaced with latest versions of computers that have fast working processors and user-friendly interface. These hardware will be supporting the every software that will be functional to get the work done. The organization will be Wi-Fi enabled with high speed internet connection.
- Software upgrade- The whole IT system needs to be upgraded. For this purpose, an IT service firm can be contacted to fulfil software requirement of the organization. All the tasks, like manually preparing list of cash and cheques that has to be deposited in the bank, will be performed through these software. By this way, the chances of human error and delay will be reduced.
- Cloud computing- The organization needs to get license from third-party provider to get access to cloud so that information can be centralised.
Non-functionality requirements such as usability, maintainability, security and performance (Li et. al., 2014) are difficult to deal with sometimes as it may involve various other factors such as compromising quality or employee’s dissatisfaction. Here, the non-functionality requirements that meant to be taken care of are:
- Security- The financial transaction will happen through the information system, therefore, it must secure from theft. Also, client’s confidential information will stored in the database so it must be safeguarded form hacking or data theft.
- Reliability- The new system must be well reliable as the replacement or repair may cause unnecessary investment.
- Training- The staff needs to be trained to use the upgraded information system. They must be encouraged to learn the new methods of bank transaction, appointment scheduling and data processing.
The stakeholders involved are; Number-One Medical Centre’s management and the clients. Whatever the outcome of the new system will, be it will be affecting the whole organization either in positive or negative way. Therefore, directly affecting its customer.
The three most useful investigation techniques are:
1) Joint Application Design (JAD) - This technique is engages user into system development (Sensuse et. al., 2020). User are directly and actively involved in designing the new system. In this technique, all the staff (here, doctor, manager, clerk and nurses) come together to discuss about the existing problems and the potential solution. By this method, the new system can be designed according to the expectation of the user.
2) Throw-away prototyping- In this method, the system is set up immediately on user’s request. The user demands modification and fixes while working on it. This system works on the basis of trail versions, where the system is modified according to user’s feedback until the user is completely satisfied. This method is implemented when the user request is unclear or tools are readily available to build the prototype. However, this system requires a lot of time and investment before the finalization of the design. Also, system development life cycle (SDLC) is often ignored.
3) Business Process Reengineering- This method involves search and identification in business process to achieve revolutionary improvement. Specific activities of the organisation is identified which could lead to improvement. During business process reengineering, use of IT system can contribute to higher revenue of the organization (Huang et. al., 2015). This method focuses more on outcome and customer, therefore, employee’s dissatisfaction could arise.
