The information system is the part of information and communication technology that refers to the technology that collects and store information for managing the business process and assist in decision-making.
The study includes the description of the information system development within a hospital. The study is divided into three sections such as Requirements Specification Report Assessment Criteria, Design Specifications Report Assessment Criteria and Performance Test Plan Assessment Criteria.
Usability Evaluation of Laboratory and Radiology Information Systems Integrated into a Hospital Information System: Giving astounding social insurance administrations can advance general wellbeing altogether. Organization of Medicine (IOM), refering to numerous investigations, affirmed that data innovation and data frameworks can assume an essential part in giving protected, opportune, compelling, and productive human services administrations (Dinh et al., 2013). Such frameworks can possibly advance patient security through giving access to astounding data amid clinical basic leadership forms. Right now, healing center data framework (HIS) is the most well-known and boundless data framework in doctor’s facilities (Nabovati et al., 2014). HIS is an incorporated framework including various subsystems which bolster data prerequisites of various offices.
Critical Factors of Information System Implementation: Inside this area of the writing survey the basic achievement factor with respect to different IS execution at different levels has been given (Kateb, Swies & Maqableh, 2014). The acknowledgment of the elements that are significant for making the execution fruitful is imperative. The basic achievement elements of IS usage can be sorted as specialized variables, ecological elements, venture administration factors, correspondence factors, venture group factors, authoritative elements and item factors. The help of the best administration, arranging of the task, planning venture, venture correspondence and numerous more are top most basic achievement factor (Laudon & Laudon, 2016). Different diaries has found that the hazard administration is likewise a basic achievement factor as far as data framework usage. Then again, few of the basic achievement elements might not have effect on the venture achievement, for example, experience of undertaking administrator, staff compensate and some more.
Components of Information System: The data framework gathers information from different I/O gadgets and different sources. Keeping in mind the end goal to store and process these information, different equipment and programming parts are required. The segments of the IT technology are as following.
Investigating a New Framework for Hospital Information System Adoption: Doctor’s facility Information System (HIS) has been intended to give various esteems to the medicinal services group and in a roundabout way give advantages to the patients. In spite of this exclusive a couple of clinics in Malaysia have really received it, subsequently this paper by depending on auxiliary information intends to give more knowledge to the writing audit of HIS selection with regards to Malaysia. In light of this, the examination presents another mix of three hypotheses to be specific Technology Organization Environment (TOE) system, institutional hypothesis alongside Human Organization Technology (HOT-fit) model to address the moderate rate of HIS selection by Malaysian open healing facilities (Ahmadi, Ibrahim & Nilashi, 2015). We contend that each hypothetical point of view has its own particular logical influence and that a mix of these three encourage a significantly wealthier understanding of Information System (IS) execution with respect to the full scale level investigation. Along these lines, it is trusted, to speak to a few headings for future research to exhibit the relationship existing in our new proposed look into structure where clinics by focusing may make a move with a specific end goal to accomplish a superior HIS appropriation basic leadership.
The process initiates with the restoration of the patient. The receptionist registers the patient at the front desk. After the registration is complete, the schedule planner makes an appoint for the patient with the doctor. This purpose of this appointment is only for initial diagnosis. The doctor is responsible for doing the diagnosis and after the diagnosis is complete, the doctor will decide further treatment or release the patient. The patient is released on two conditions, if the patient treatment cannot be done or patient needs no treatment.
If the doctor believes that a doctor with other expertise can assist in patient treatment, then the doctor refers the patient to that expertise. There is a possibility that the symptoms of illness may not be clear. In this situations, the doctor will prescribe further tests prior to determining the illness.
Function, biochemical, visual and many more tests are there to do. Individual specialists carry out the tests. After completion of test, the result is sent to the doctors. These results assists the doctors to follow-up diagnosis. After the completion of diagnosis, the doctor has the choices of releasing the patient, consulting with other specialists and requesting for additional tests or therapies. The formulation of prognosis is done on the basis of the outcome of therapies.
Functional Requirements: The functional requirements of the system are as following.
Non-Functional Requirements: The non-functional requirements are as following.
Functional and non-Functional Requirement Visualization:
In order to address cloud solution in the Hospital Information System management, the cloud solution is chosen to be Infrastructure as a Service (IaaS). This basic cloud service model acts as an infrastructure to serve multiple customers with storage and network transfer (Sultan, 2014; Lian, Yen & Wang, 2014). In this, IaaS service model, service is generally offered to deliver data transfer from single server among several servers grid to integrate the single server within VPDC (virtual private data center). The IaaS model acts as most used cloud service model along with offering SLA (service level agreements) for better performance metrics (Wan et al., 2013). Firstly, it needs to be discussed that why SLA is important for cloud solutions in this particular system design. The important points that are considered as mentioned following:
SLAs in cloud solution maintain some general yet specific Key Performance Indicators (KPIs); that are:
In this Hospital Information Management system, SLA formulation needs to state some requirements to be addressed. The SLA requirements are mentioned as following:
Here, a general structure of SLA is shown with some parts as SLA definition, SLA components and categories, customer and service provider definition, determined qualities, and SLA parameters (He, Fan & Li, 2013). The SLA concept is shown as following:
SLA Components: An ideal SLA consists of some major parts that emphasizes on SLA with important aspects that are mentioned as following:
Purpose: SLA should provide a purpose why SLA is formed
Parties: SLA mentions which parties are to be involved and interested in the SLA and their individual jobs (Rodrigues et al., 2013).
Validity period: The validity period should state the time that is covered with SLA. The validity period is defined with starting time and ending time of the service.
Scope: The scope of SLA should state the services that are to be offered; SLA structure should elaborate service levels so that customer can recognize procedure of services (Demirkan & Delen, 2013).
Restrictions: The restrictions are set for taking essential steps regarding supply in required service levels.
Service-level Objectives: The service level objectives are considered from the customer for approval and the service level objectives include several groups of services indicators those are identified as availability, performance, and reliability (Benharref & Serhani, 2014). The part of the service level and availability takes target level for completion. The service level objectives may consider day-time restrictions that is related with describing validity.
Service-level Indicators: The service level indicators are effective for measuring the level of the services provided from the cloud vendor.
Penalties: The penalties described required parts where vendor cannot achieve the SLA goals (Castiglione et al., 2014). In case, the SLA is considered with external vendor, there is necessary chance of taking proper choice of concluding the contract as well.
Optional Services: The optional services are not ordinarily required from customer; however, these services might be relevant for considering as exclusion.
Exclusions: The exclusion states the parts that are not included into the SLA though those are relevant for the Service Level Agreement exceptions (Haux et al., 2013).
Administration: This administration part considers defining formed SLA with achieving and measuring the SLA goals.
In short, an SLA cannot guarantee that the organization will get service that it states, the SLA not any more than a warranty that can guarantee that service will be continuous. In particular manner, SLA is effective for picking up good service out of bad ones. On the other hand, SLA can be useful for avoiding the risks of choosing a bad service (Weaver et al., 2016). Once, a good quality service is chosen; it can mitigate the requirement of client with including quality and appropriate service. The way of designing SLA is for supplying sufficient data or performance metrics so that client can select services before making payment. SLAs are included in basic content and forms or toolkits can use them as well. The cloud vendors can prepare designs of the systems in such a way so that the measurement of services can be gathered and matched with SLA determined metrics (Russ et al., 2015; Soares et al., 2015). Therefore, most important part of any SLA is the service quality and identification of SLA parameters and metrics. These attributes in any SLA can easily measure how the service can be available to the users from the cloud vendors.
3.1 Performance Test
In order to address the testing schedule of the risks and the entire cloud solution, the testing measures should be incorporated. The test measures could be performed in terms of choosing how the test plans should be prepared and based on the testing criteria (D’Andreamatteo et al., 2015). The test plan includes following measures:
Testing during Selection: When selection process is to be conducted for cloud solution, multiple cloud vendors should be chosen. Several options are considered when the cost is considered as well as the time and energy is considered; moreover, along with new services, possibility stays in choice making (Weaver et al., 2016). Few suppliers are yet to provide over the cloud service. The customer is dependent over single supplier once, it is called as vendor lock-in. The problems may come out to be along with supplier and therefore, some alternative suppliers can be chosen for services to be transferred. The vendor lock-in situation can be put with customer for unfavorable situation, contract negotiations can be used (Mebazaa et al., 2015). Choosing particular service and supplier, the authority should consider a timely process to consider the budget planning. The managing directors and senior managers can overview the situation, the members, customers, and other suppliers can meet agreement (SLA) before the service delivery and the vendor’s lip service can pay within selection process.
The pitfall and fault in selection so that initial objectives may fail on the implementation stage. This problem occurs when customers can get better cloud services so that different features and options will not be chosen as selection criteria (Peppard & Ward, 2016). Another pitfall can occur with more concessions along with criteria particular with particular services with best-fit requirements. The selection of cloud vendor should be divided following steps:

Another pitfall can occur with more concessions along with criteria particular with particular services with best-fit requirements. The selection of cloud vendor should be divided following steps:
Furthermore, the cloud vendors should be interviewed about the SLA and the service quality as well so that the entire service could be effective for Hospital Information System.
