SYAD 310 System Analysis And Design Assessment 2 Answer

Answer :

Executive summary 

The Pathology Lab system has been designed to start replacing their existing manual, paper-based system with any pathology laboratory. Control of the following information is the new system; Patient details, room size, medical and administrative personnel and patient data. All resources are to be delivered efficiently and cost-effectively, with either the goal of reducing the time and money currently necessary for such activities.

A considerable division of the business of some Pathology Lab includes the collection, administration and well-timed recovery of large quantities of in sequence. This information includes; waiting lists for confidential patient records and medical history, details, personnel scheduling and various facilities. All this knowledge needs to be handled in an efficient and cost-effective manner, so that clinic's resources can be successful The PLS used can automate the efficient and error-free management of the Pathology Lab. It aims at standardizing data and consolidating data that guarantees data integrity and eliminates inconsistencies.(5)

Introduction 

Australia has a well-equipped clinic with all the latest equipment at Universal Pathology Lab in Australia. The clinic has separate waiting and consultation areas which allow sufficient space for patients to comfortably wait at the clinic. The doctor is a specialist Pathology Laboratory providing a variety of medical facilities.  Payments can be made by various modes such as cash, debit cards and cheques.

Please scroll up to the top Pathology Lab address and contact information at Australia. At the moment Pathology Lab uses a manual management system and holding vital details up. The current system requires great many paper forms extend right through the pathology lab, with data stores infrastructure Management. Frequently in transit, forms are lacking to ensure a rigorous audit process between departments that no sensitive information is damaged. There are several versions of the same details In the Pathology Department, and can result in data discrepancies in different data Shops. (1)

Tasks

1. A major part of any Pathology Lab's operation includes collecting, handling, and retrieving vast quantities of information in good time. These include: client identifying information and health information, nursing records, room and patient scheduling, staff scheduling, operating room scheduling and waiting lists for various facilities. All this in sequence must be handled efficiently and cost-effectively So that the resources of an organization can be used efficiently will PLS automate pathology laboratory operations to make it more useful and free of charge fault. It provides standard data and merges data maintaining integrity of the data and elimination of discrepancies. (3)

For Universal Pathology Lab, the types of system requirements need to be focused on are as follows: 

1. Security: UPL requires system to be secure one, i.e., free of threat or data loss.
2. Immediate knowledge retrieval:-Proposed main objective the framework is designed to provide for rapid and effective information retrieval. Information type will be available whenever the user so requires.
3. Immediate storage of information:-Many are available in manual system issues of storing the greatest amount of information.
4. Simple to use:-The device should be, and should be, easy to run that it can be produced in a short time span and fit into the Small user allocation.
5. Authorization: only authorization person can access not can access third party 

2. Fact finding is data analysis and information based on approaches that involve sampling of existing records, review, assessment, evaluations, selection, prototyping and joint requirement planning. Technology analysts use effective fact-finding methods to evaluate and execute the existing framework. It is very important to collect the necessary facts for the application of tools in the creation of the method, although techniques cannot be used quickly and effectively before sufficient collection from facts. It approaches are old in the initial stage of the System Creation development process, including the universal pathology lab's mechanism, design, and pre - completion assessment. Even the information used in the information system can be evaluated using three steps: information-facts used to produce valuable information, process-functions for achieving objectives and user interaction interface designs (6)

Visits to Research and Web

In pathology lab, universal pathology and usability testing is a way of examining problems that have already been discussed by other sources that could be human. The analyst visits other business, which had previously experienced similar problems, to fix the problem requirements. In addition, the analyst can collect data from the database, text sources, research papers and the Website as well.

Pros

If the problem is already solved it will save time. Researcher should recognize how various public have solved the identical problems before. Researchers are still aware of the information regarding the new development system.

Cons

Relevant information source require authority to connect. Since issue history is not registered, the problem is hard to solve.

Surveys are in fixed format

Fixed-style questionnaires are designed to collect in rank from predefined question design. Users are able to choose the outcome of the replies given. There are three types of fixed-format questions: questions graded by multiple choices (strongly accepted, accepted, no opinion, disagreement, positive disagreement), questions classified (numbering individual tastes).

Pros

Persons must fill out a form and provide the responses freely to the researcher. That is cheap technique. Users are more likely to respond to detailed responses because their personal information is not expected to be revealed. Simple to quantify and evaluate responses.

Cons

It may receive partial replies. Psychoanalyst can't detect user reactions in the language of the body. It has no ability to describe either abstract or incomplete answers. Hard to prepare good questionnaires.

Effective Appointment

Structured Appointment is an Appointment that requires predetermined of questions. The close-ended type of questions is used in a formal appointment to limit the answers to decide the choices, concise and clear responses to the appointment.

Pros

They have faith respond questions more efficiently by inspiring an appointment. More input from the Appointment the machine analyst will look at. System analysts may schedule more relevant questions for appointment, or change responses for each participant. Device analyst can understand the Appointment' nonverbal messages by perceiving body movements and facial expression.

Cons

Appointment for technique discovery is time-consuming and costly process. Additionally, communication abilities of the computer researcher affect the arranging time for appointments.

3. A business should manage it appropriately, just as it manages other resources, to optimize the utility of knowledge. Managers need to realize that cost is correlated with all information being produced, distributed, protected, processed, and retrieved. While knowledge is all around us, it is not free, and it should not be taken for granted its strategic use to competitively place a company. (1)

System development tools

Computer –Aided software tools

Database- MYSQL create a database pathology test

Operating system-appointment, instruments  

SDLC method, and the study and implementation of object-oriented systems

System development methods  

Technical feasibility 

The project entitled "pathology test Framework" is technically feasible due to the function listed below. Java designed the software which is the graphical interface for Users.

This provides a decent reliability, usability and flexibility, all of which make Java suitable for this design (Sarangi et al., 2015). So Java’s new developer is a versatile language.

Method economically feasible

The computerized system would help automate selection n that leads the revenue and data of the organization. With for this software developer, the use of computers and man powers is expected to increase by about 80-90 per cent. It is expected that expenses involved by not designing the system will be fantastic, because valuable information can be necessary manually.

Method of operating practicability

Under this agreement, the administration would know the details of each agreement that can be submitted and the data will be kept as distributed, and if any inquiries will be found according to the demands and requirements of everyone concerning that particular contract.

Modeling

Use Case Diagram 

Using model behavior case diagrams in a system, and let users understand what the person requires (Atkinson et al., 2002). The person who has the stick is what is considered an actor. Use case description to outline a process and explain who can do it, and more importantly, which they can't do. Use case diagram contains use cases and actors, which displays the relationships between use cases which directors. (3)

A Use situation is a definition of a series of action sequences by people who wished it to be made as an ellipse containing a solid line, and therefore its name. Analysis of the use system is a behavioural diagram that displays a sequence of use scenarios and participants and their connections. It's a mix of the performers and the use cases. In the real world an actor represents an entity.

• The goal is to show the relationships among case of use and participant.
• To represent device requirements from a user perspective.
• An individual can be an end-user of the application, or an outside machine.

Actor- Appointment, patient, pathology lab 

Use case- Login/signup is main and secure use case for visitor and client 

Take scheduled time and their type like daily, weekly, hourly

Appointment scheduling date and time 

Patient report, payment, and assurance 

Pathology lab for testing 

Data Flow Diagram 

Context Diagram

A context-level DFD for both the system produces information for system use by the primary external entities and consumes the system-generated information. The labelled arrow represents objects with data or object hierarchy. The context diagram gives various views of information technology. Rectangles also called particles represent data entities identified by indicators marked with a transformation. Here the DFD is interpreted in a hierarchical way i.e. the entire structure represents the first design of transmitted data (Jilani et al., 2011). Consequently the DFD refine the background diagram (level 0 DFD), giving the information to each following phase. A DFD 's function is to show the scope and limitations of a whole system (Selamat, 2019). It can be used as a communication tool between a project manager and whoever plays an advantage of those opportunities and acts as the basis for comparison for a system shift.

The patient will pick the appropriate test and the laboratory will be charged the cost of the test while the images are collected as cash upon distribution. (2)

Zero level Diagram

A level 0 data flow diagram ( DFD), which is also known as a system process, shows a full data structure and illustrates how it interacts with external entities (Ibrahim and Yen, 2010). This explanation Context level level 0 shows how a system like this might work in a traditional business.

ERD 

This diagram of the ER (Entity Relationship) represents the model of the Laboratory Management System Entity.
