SYAD310 Systems Analysis and Design

Introduction 

Sydney medical Centre is one of the growing practices in the Sydney. The Centre has rapidly increased the number of the doctors and the patients associated. As a result, the owner of the medical Centre has decided to develop a new information system that will have the potential to handle all the basic business requirements. The need to understand the issues are faced with the current system becomes very crucial. The current system is unable to provide real-time information towards medical staffs. As a result, there is a huge need to design a new system. The focus of the assessment to devise a new system with all the necessary functional requirement so that it can provide huge opportunity towards the Sydney medical Centre.

System Requirements For New Information System Of Smc

Sydney medical Centre requires a new information system that will have the potential to easily handle the information with the patient’s requirement. In order to develop the system efficiently, it is important to obtain sufficient information regarding the system (Levykin, Ievlanov and Neumyvakina 2017). The different types of system requirements that are going to be collected before developing the new system for Sydney medical Centre include functional requirements, non-functional requirements and technical requirements. Each requirement is needed for the purpose of addressing the way new information system is going to operate. The requirements are discussed below:

• Functional requirements: Functional requirements are referred to the system requirements in which the functionality of a system is being identified. With the help of a functional requirement, it becomes easy to identify the basic product features that are going to be developed (Olsina and Becker 2018). At present Sydney medical Centre aims at developing a new information that will have the potential to do the functional requirements including hourly generating appointment report, listing daily appointments for each provider, weekly providing report for each list, reporting on weekly patient statement and developing monthly insurance company report.
• Non-functional requirements: The non-functional requirements are referred to the attributes associated with the system. It becomes very crucial to identify the basic attributes that are going to be offered while accessing a system. The new system is proposed within Sydney medical centre with the objective to provide easy accessibility over the medical information towards medical staff (Behutiye et al. 2017). The non-functional requirements that are going to be kept in mind while developing the system include easy accessibility, reliability, security, integrity and availability. It is important to ensure that this system is developed with the motive to provide a better accessibility over all the information that is stored within the system.
• System technical requirement: System technical requirement in order to develop the information system successfully for the Sydney medical system (Bahill and Madni 2017). The technical requirements that are needed for the development of information system include database, knowledge base models, system interconnection model and interface development software.

Fact-Finding Methods

Fact finding technique is used for the purpose of analysing the basic requirements associated with the system. It can be stated that with the successful utilisation of a fact-finding technique it becomes easy to understand the requirements associated with the new system. It can be clearly stated that the prioritization of a set of requirements can be carried out much more efficiently with the help of fact-finding method (Alzahrani 2020). The most suitable fact-finding method that can provide support in the development of new information system for Sydney medical Centre are examining existing document of the current system, questionnaire and interview. These methods have the potential to collect sufficient number of facts regarding the system and will also provide opportunities for developing the new system much more efficiently.

• Examining documents: Examining document is considered to be helpful as these helps in gaining insight regarding the requirement of the existing system. This helps in understanding the major issues that were faced with the existing system. It can be stated that by examining the documents, quick information can be shared (Kotzyba et al. 2017). The major advantages that are offered with the use of examining documents include excellent tracking of information and better way of identifying the data types and formats. However apart from the advantages there are certain disadvantages that also impacts the performance of the examining document fact-finding method. The disadvantage includes unnecessary data and inefficiency within the process.
• Interview:  Interview is the most frequently used fact-finding method. With the help of Interview, it becomes easy to obtain information from the users. It is very crucial for the Sydney medical staff to understand the existing issues so that it becomes easy to implement new changes (Matsuura and Schenk 2017). Once the interview provided with proper details regarding the challenges faced by the existing system then it will become easy to develop a new solution. These provides a face-to-face communication and ensures that effective way of dealing with the staffs are being obtained. The major advantage that is offered with the use of interview fact-finding process is easily the easy way of opening axis over information and low-cost way of communication (Kreb 2017). However, there are certain disadvantages that include time-consuming process, inconsistency and inefficient data sets.
• Questionnaire: Questionnaire is the method that helps in conducting surveys. With the help of questionnaire, it becomes easy to obtain sufficient information from a wider set of people. These are basically divided into two format that include free format and fixed format a type. It can be clearly stated that this fact-finding method is considered to be much more efficient and can obtain high responses. The benefits that are expected to be offered with the selected approach will offer better practical analysis, better scalability and easy way of analysing and visualising the data content (Devaney 2019). Apart from these the major disadvantages that are needed to be kept in mind while developing questionnaire are lack of honest answer, chances of unanswered questions are high, lack of personalisation and some questions are very difficult to analyse due to inappropriate answers. As a result, it can be stated that the questionnaires are must be carried out only with a limited number of members.

Two System Development Tools 

System development tools and techniques are used with the motive to ensure that proper way of system analysis is being carried out. It becomes very crucial to ensure that a proper system development tools are being selected while developing a new information system. After understanding the basic requirements associated with the Sydney medical Centre it can be stated that the modelling and Object-oriented analysis are the most suitable tool (Bourgeois-Bougrine et al. 2017). With the help of these two tools, it will become easy to provide with the better opportunities. The need to identify the system requirements becomes very crucial as these will help in overcoming the existing challenge.

• Modelling: Modelling is used for the purpose of producing graphical representation of a concept or process that assistant developer can easily analyse. The current requirement of the information system is to develop a much more flexible solution that will be capable of setting necessary information regarding the patient medical data. A business modelling or requirement modelling helps in describing the information much more efficiently. These helps in understanding the way communication must be carried out. With the help of a modelling technique, it becomes easy to develop a new information system with all requirements.
• Object oriented analysis: Object oriented analysis is referred to the technique that is used for the purpose of understanding the basic requirements associated with the information system. The system analyst is responsible for developing and maintaining information system requirements with the use of an Object-oriented analysis tool (Özkaya and Korkmaz 2017). It can be stated that information can be analysed much more efficiently with the proper utilisation of these tools. These also provides a better way of creating different types of diagram that include UML diagrams.

Two System Development Method 

The system development methods are used for the purpose of developing the basic requirements associated with the system. According to the current requirements associated with the Sydney medical Centre, it can be stated that the two most appropriate system development method include agile methodology and waterfall methodology. These two methods have the potential to offer huge support towards the development of a Sydney Medical Centre.

Agile Software Development Method 

Agile software development method is referred to the most suitable software development and approach it through which efficient software is can be presented. Agile software development method follows iterative flow of a project for the purpose of a developing a new system. The major advantage behind selecting the agile development method is the fact that each approach is being represented in an iterative manner (Zamudio et al. 2017). Agile software development follows the five basic principles at the time of developing a new information system. These include improving agility, just-in-time designing and coding, unit testing, writing object-oriented code and applying agile design patterns. With the help of these approach, it becomes easy to carry out the development of a system. It can be clearly stated that Sydney medical Centre will have the ability to develop the information system much more efficiently with the use of agile software development (Tam et al. 2020). The expected advantages with the agile software development include rapid development of the product, continuous delivery of useful software, customer satisfaction and allowing changes at the execution time.

Waterfall Software Development Method 

Waterfall software development method is referred to the software development in which a linear sequential flow. With the help of these methodology, it becomes easy to carry out the development of a new system. The major reason behind considering waterfall model as the most reliable ones for developing Sydney Medical Centre system is the fact that waterfall model offers easy way of analysing requirements and defining the products (Nugroho, Waluyo and Hakim 2017). It has been observed that there are no ambiguous requirements present while developing a software using waterfall model. Apart from these the major advantages that are offered with the waterfall model include easy way of understanding milestones, efficient way of arranging tasks and well documentation.

Recommendation 

After evaluating both the methodology it can be clearly stated that Agile software development method is the most suitable approach. With the help of these method, it will become easy to achieve the business requirements (Malik, Ahmad and Hussain 2019). It has been observed that Sydney medical system will be capable of operating efficiently with the utilisation of agile approach.

Conclusion 

SMC system will be capable of offering better efficiency towards the patients. It can be stated that the new system will create opportunities towards the patients and staffs. The need to develop an efficient system becomes very crucial as this will be capable of streamlining the business performance. The report has successfully evaluated and analysed the basic requirements associated with the SMC system. The paper has ensured that sufficient amount of information is being analysed successfully so that it becomes easy to achieve the target. The paper has discussed all the basic requirements associated with the system so that it becomes easy to achieve the target. The developed diagrams have helped in developing system much efficiently. Hence it can be concluded that the implementation of new system will help in bringing a streamlined system within the business.
