Reflections and Conclusions:
The aim of the report is to develop and frame a Medical Center Management System based on the needs of the given case study NMC. Hospital management program is designed to meet the special needs of small and large hospitals worldwide. All the modules and features required are specifically designed to meet your needs. Customers in India and overseas have approved this kit. They are not only pleased and appreciative, they are extremely satisfied. The entire application is cloud based and designed with the latest technology on 3-tier architecture.
The application's sound database makes it easier to use and extend. The kit can be highly personalized and tailored to our customers ' preferences and desires. Long analysis of the functionality and basic specifications of the hospital has given it a great technical and usage-oriented form. This includes all appropriate modules including registration of patients, medications, doctor, wards, admin, storage, patient appointments, bill payment, record changes, discharge information etc.
Manual record keeping takes time and is particularly vulnerable to mistake. The purpose of this project is to automate or render online the daily operations, such as room tasks, the admission of new patients, patient discharge, doctor's appointments and finally measure the bill and so on. I have tried my best by using organized & streamlined technique & menu-oriented interface to make the complicated Hospital Management System as simple as possible. Hospital is an important part of our life, supplying patients with different illnesses, which could be triggered by change in the environment, heightened workload and mental distress tension, etc, with the finest care services. The hospitals need to keep track of everyday events and accounts of their patients, physicians, health care professionals, volunteers and other personnel that keeps the hospital functioning smoothly and efficiently.
But it is incredibly tedious and error prone to keep track of all the events and their reports on paper. The measurement of constant population and number of patients attending a hospital is often very inaccurate and time-consuming. It is inherently untrustworthy, inefficient and error-prone to archive and preserve these papers. Also, keeping these notes on paper isn't commercially and technologically viable. This keeps the manual method running as the base of our project. An automated version of the manual system called "Health Institutions Administration Support System" has been developed.
The key goal of this initiative is to have up to 90 percent with a paperless hospital. It also attempts to provide the current networks with reliable, low-cost automation. The device delivers excellent data protection on all user experience levels and provides recovery and replication features that are comprehensive and efficient.
In our product growth phase, we employed the Iterative and Incremental Progress Model (IID). This approach to construction is also called Iterative Waterfall Growth. Iterative and Gradual development, designed to follow the more conventional waterfall paradigm, is a software development technique. This model has been planned to accommodate such a large undertaking. In specific, the broad and complex project calls for increased production and research. The type of waterfall is renowned for its continuous cycle of checking. Therefore, I prefer to build my program with the waterfall pattern.
The waterfall model has other advantages:
Any framework of information needs is important to build. These are classified into two groups of operational specifications, concentrating on what system needs to do and non-functional requirements based on how the system should operate. (Eriksson 2012) Specifically:
Functional requirements are as follows:
Users must register to use the system
Employee, Doctors, Owners and customers must be given valid username and password to access the system
Different users are given different accessibility depending upon there authorization level.
Payment record must be controlled by the system
It will keep track of activities that affect the system
Non-Functional requirements for the system are as follows:
Tells what response time of system is when the system is used by multiple users
Tells how much data can system store
How well system is maintained whenever there is change done in the system
Tells how safe the system is
Tells about the user interface and how easily user can use the system
The most critical factor of implementing a program is cost-benefit analysis. We evaluate the decisions through this method. It outlines both the project risks and benefits. The costs accrued must be transparent, indirect, measurable, incentive and risk costs. Direct and indirect income and intangible gains shall be the assets involved. On the basis of the project cost benefit analysis, the practicable study is performed. Such three main criteria test whether or not the proposal is feasible:
Cost-benefit analysis is a straightforward method to calculate the value of a project against the cost of its output. In the implementation process of the project, project administrators use cost-benefit analyses to explain the importance of a project. The contractor and project manager ought to explain the project at the start of the project to gain permission from the organisation. The cost-benefit analysis measures the cost of the project to its market interest. Few businesses tend to carry out projects that cost more than the amount they generate. This means that project managers assess the cost-benefit by generating data about the gain interest and the project expense.
All project-related calculations are provided in Excel Sheet. The project originally spent $150,000 and was cut by 5%. The estimate is completed and the results show ROI is 28% and the split only happens after 2 years and 95 days, which means that after 2.26 years we get a return. This means that the Hospital life system's electronic initiative is feasible.
The structure of work breakdown is essential to the life-cycle and scheduling of the project. This explains the hierarchy of tasks and stages that illustrate the project process. The tasks are specified and then divided into sub-tasks which indicates the number of levels of general project knowledge. (Devi & Reddy 2012) This figure shows the breakdown of the project work structure. The project has five activities such as the requirements research, device research, coding & checking. As seen in Figure, these tasks are split further into subtasks. These tasks indicate that they are intertwined and dependent on each other and influence the length of the program.
Work Breakdown Structure
The project schedule is the duration of the whole project's task. Activities depending on which project costs are measured are described on these assignments. We can test the feasibility of a project by using the project plan. (The 2010 Longer). The Gantt diagram suggests the scope of the assignments. It indicates that all tasks can be done over a certain timeframe, some of which are different. The entire project is finished within 260 days, which demonstrates how practical this project is. This shows that we can defer and complete our project by 105 days. The tasks are interrelated by a supervisor who says these have to be done before new tasks start otherwise the duration of the project may increase. The allocation of resources is also possible because of the project. There is a crucial way that says that these tasks cannot be delayed because the project may be delayed.
Stakeholders are a group of individuals who are interested in project creation. (Jacksons & Satzinger 2015 in Brussels). Two categories of stakeholders interested in this initiative are:
Investigation methods are very effective in the design of applications because they tend to satisfy various kinds of system construction criteria. They also state the participation of multiple stakeholders. Many testing strategies such as interview, researcher, test, etc. are available. We have taken the prototyping from this device production based on which the most popular methods of study are listed below:
Interview & Question:
In this method, the participants in the previous framework are interviewed and information based on the interview obtained. The interview will contain questions that are open-ended and close-ended. This will allow us to see what are the weaknesses in the former program and what the customers want from the current system.
This methodology can be conveniently used in this program implementation as the previous system is paper based and asking customers can provide an understanding of whether a new system is required.
Business Documents Analysis:
This approach analyzes the issue of the present structure, corporate principles and the likelihood of meeting future specifications.
This method is useful here, as it takes less time and the concerns relevant to the previous system can be conveniently illustrated.
Where fewer participants are involved and system development is difficult, prototyping inquiry approach is used.
That is a helpful strategy as the author can quickly adjust this according to request if the user makes any changes to the program.
A small health facility, Number-One Medical Center (NMC) Inc. The organization presently consists of eight wage-earning doctors, 12 nurses, 4 service personnel, and 3 employees. Clerical staff conduct duties such as collection, email, cash refunds, payroll and arranging of meetings. On the day of their appointment, most patients pay for treatment in cash or check. But the doctor to provide the respective services often accepts loans on the basis of an interview. The doctor file a report with one of the workers to establish a receipt for the data created by the doctor when the payment is accepted. The constraints in this project include teaching the user how to use the new program, internet access to the device, login authentication, system repair and routine maintenance. The successes are that we introduced the new program effectively over a given period of time and we benefit after three years.
After functional and not functional specifications have been defined, the Hospital Management System concept was introduced using the Waterfall and Prototyping methodology. We calculate the cost of the project and we analyze the preparation of the project. This program is easy to understand and user friendly and holds all the details that avoid replication. In addition, all prior device issues are eliminated and implemented in compliance with the user specifications and the budget given.
