Software Engineering and Service Science †MyAssignmenthelp.com

Question: Discuss about the Software Engineering and Service Science. Answer: Introduction Headspace is a popular organization, which works with youth generation aged twelve to twenty-five, who experience mental illness and ill health. Anxiety and depression are the most common mental health problems, although there are many other mental illnesses as well. Every time these patients need to tell their problems again (Pearce Bainbridge, 2014). The young people discussed little and even stopped talking about their problem. This makes it harder for the professionals to help them for their problems. Initially, a social worker of Headspace, then the medical staff in a hospital, maybe a psychologist, a psychiatrist, and a general practitioner sees them.Currently, funds are raised to form a system that will record the patients story in the first time. This will provide authority to the specific professionals, so that the case studies and their story can improve, and the young patient can be facilitated appropriately and more precisely (Steele, Min Lo, 2012). This particular orga nization has considered opting for a cloud based solution for their project. This report focuses on the cloud that should be undertaken by Headspace for their business. The following report outlines a brief description on the need for the implementation of cloud in Headspace organization. The report covers the non functional requirements of the system and the type of cloud Headspace should opt for their business (Chen Zhao, 2012). The report further mentions about the recommended software development life cycle approach, which would be the best for the organization. The non functional requirements of a particular system deals with the attributes of a system for performing the functions optimally (Chung et al., 2012). The main advantage of these requirements is that they help in identifying the critical qualities of the systems, the requirements of the system and the constraints of the system. These features are taken into consideration for the implementation of any project. These non functional requirements has an important impact on the success factors of the project (Balaji Murugaiyan, 2012). The various non functional requirements for the Headspace case study with respect to FURPS or functionality, usability, reliability, performance and security are given below. This is the most important criteria for this particular project of My Health Record system. The information system would be having all the necessary information related to the patients (Chen Zhao, 2012). Hence, it is extremely important for the system to enable a particular option for updating and accessing the information according to the needs of the user. The main functional requirement of this particular system is the adaptability. This is the second most important criteria for the non functional requirements of this project. The software can be easily learnt and this is the main requirement under usability (Galibus Vissia, 2015). The interface between the software and the user should b user friendly so that it can be easily accessed by all users. This is the most important requirement under the non-functional requirements. The system should be reliable enough as it would be storing all the confidential data or information regarding the patients (Jain Nandakumar, 2012). Moreover, the system would be automatically updating the information. Therefore, the reliability of the system is essential. Moreover, for cloud based environment requires utmost reliability. Performance is the fourth important criteria for the non functional requirements in any project (Li et al., 2015). If the performance of any system will not be up to the mark, it is useless to implement that particular system. The system should provide perfect performances and should be flexible in nature. The information that would be stored in the My Health Record system will be extremely confidential and sensitive in nature. The security of that information is necessary (Galibus Vissia, 2015). Unauthorized access should be strictly prohibited at any cost. Biometric authentication should be present in the system so that only authenticated users can access the data or information. The Functional Requirements of the System vs The Non-Functional Requirements The functional requirements of a system evaluate the probable or estimated functions of a system. In other words, these are referred to those particular functions that are expected to come out from the system (Chung et al., 2012). This is different from the non functional requirements, which deals with the qualities of a system. It deals with those qualities that are evident to be present in the system. This is the basic difference between the functional requirements and the non functional requirements of a system. Headspace has decided for opting cloud based solution for their business (Galibus Vissia, 2015). There are four types of clouds available in the market. They are the private cloud, public cloud, hybrid cloud and the community cloud. Public cloud is open to all. Private cloud is a closed cloud and only a group of clients can access it. Hybrid cloud is the mixture of both private cloud and public cloud (Rittinghouse Ransome, 2016). Community cloud is a fixed group of users that has users with same requirements. The suggested cloud for this particular case study is the Hybrid cloud. Hybrid cloud is the mixture of both private cloud and public cloud (Jain Nandakumar, 2012). This eventually means hybrid cloud has several features of private cloud as well as several features of public cloud. Choosing a public cloud would not be good idea as it always has the chance of attacks. Private cloud on the other hand, does not allow any unregistered users to access it. This becomes problem many a times. Hybrid cloud is the solution for this particular problem. Almost everybody can access a hybrid cloud, however wit utmost security (Li et al., 2015). Whenever, hybrid cloud detects any intrusion, it immediately blocks the entire cloud system. Therefore, hybrid cloud would be the best solution for the Headspace organization. The hybrid cloud has several strengths or advantages that make it popular and accepted by all organizations (Chen Zhao, 2012). The advantages of hybrid cloud are as follows: i) Security: This is the first and the foremost feature for a hybrid cloud (Li et al., 2014). As it has the features of a private cloud, it is absolutely and extremely secured and data breaching or intrusion is almost impossible in this cloud. ii) Cost Effective: This is the second most important feature for a hybrid cloud (Kulkarni et al., 2012). In spite of the combination of both private and public clouds, hybrid cloud is extremely cost effective in nature and can be easily afforded by all organizations. Cloud Environment Weakness In spite of having several strengths, hybrid cloud do have some of the major weaknesses or disadvantages (Rittinghouse Ransome, 2016). The weaknesses of hybrid cloud are as follows: i) Implementation Cost: The implementation cost of a hybrid cloud is much more than in a private or public cost (Li et al., 2012). However, once implemented, the maintenance cost is lower than others. ii) Movement of Data: The data is constantly moved from the private and the public clouds (AlZain et al., 2012). The hacker can get the access of the data during this movement and can breach the data easily. Therefore, it can be concluded that hybrid cloud would be the best solution for Headspace organization. The Software Development Life Cycle or the SDLC is the sequence of steps that is followed during the creation of a project. This life cycle has various phases and completion of each phase leads to the next phase (Balaji Murugaiyan, 2012). The phases of a software development life cycle include requirement gathering and analysis, design, implementation of coding, testing, deployment and maintenance. There are two types of approaches in a software development life cycle. They are the predictive approach and the adaptive approach. The predictive approach of a software development life cycle means the complete life cycle of the project during the initiation of the project (Tuteja Dubey, 2012). This is possible when the project scope and schedule are clear. The pros and cons of predictive SDLC are as follows: i) The scope of the project is absolutely clear and so is the schedule. ii) The planning of the project is done perfectly (Mahalakshmi Sundararajan, 2013). iv) The progress is tracked thoroughly until the completion. i) Improvisation is almost impossible as everything is done in the beginning. ii) The feedback cannot be taken as everything is pre planned. Conclusion Therefore from the above discussion, it can be concluded that Headspace is a popular organization, which works with youth generation aged twelve to twenty-five, who experience mental illness and ill health. Anxiety and depression are the most common mental health problems, although there are many other mental illnesses as well. Youth suicide in indigenous New South Wales for the age group of sixteen to twenty four has been particularly disturbing and alarming, especially amongst the local and indigenous youth. One of the major problems recognized was that a young person of age group of sixteen to twenty five with a mental illness and problem needs special attention from multiple professionals. Every time these patients need to tell their problems again. The young people discussed little and even stopped talking about their problem. This makes it harder for the professionals to help them for their problems. Initially, a social worker of Headspace, then the medical staff in a hospital, maybe a psychologist, a psychiatrist, and a general practitioner sees them.Currently, funds are raised to form a system that will record the patients story in the first time. This will provide authority to the specific professionals, so that the case studies and their story can improve, and the young patient can be facilitated appropriately and more precisely. This particular organization has considered opting for a cloud based solution for their project. This report focuses on the cloud that should be undertaken by Headspace for their business. The above report outlines a brief description about the case study of Headspace that has decided for cloud based solution for their business. The report helps to understand the non functional requirements of the system and the security of the confidential data. Relevant recommendations are also provided for the choice of software development life cycle approach. References AlZain, M. A., Pardede, E., Soh, B., Thom, J. A. (2012, January).
