my professor question is


Developing well-designed, tested, functional and reliable systems depends on a number of different processes. Today, producing and maintaining large systems is a task that is almost exclusively performed by teams of people. Not surprisingly, a significant portion of success in such projects does not strictly depend on technical abilities alone but on a number of other factors such as proper design, planning, estimation, people communication, activity coordination, project scope management, etc. This project will provide you the opportunity to experience and deal with almost every possible facet of the systems engineering process.

Running head: SYSTEMS ENGINEERING AND INTEGRATION Systems Engineering and Integration 1 SYSTEMS ENGINEERING AND INTEGRATION An analysis of telemedicine: Project scope Project Objective, Overview, and Justification The salient objective of the project is to create a feasible solution system in telemedicine. The system is Video convention structure (VCS). It applies the internet to connect hardware devices such as phone to enable sharing of high-quality images and sound (Radiol, 2012). The system relies on mobile or wireless network infrastructure. Hence, it is flexible and affordable to users List of Functionality / Scope Items The following is the list of the items in the scope of the creation of the system (Radiol, 2012): Wireless or mobile networks Computer or PCs VCS gateway VCS systems VCS widespread stakeholders VCS software End point centers Time Frame The project is estimated to take eight weeks. The project time frame will be subdivided into 3 phases. The first is seeking approval from the Local Governance Council, ensuring all the regulatory procedures are followed to the latter. This process may take two weeks. The second is the reconnaissance, which will take one week and involve establishing 2 SYSTEMS ENGINEERING AND INTEGRATION 3 research tools, study area, and study plan (Synn, 2011). The third stage is collecting data, which is expected to take two weeks. The fourth stage is data entry, analysis, and report writing. This will take three weeks. Target Customer The target customers are medical institutions in general. However, the most promising clients are medical unions and collaborative physicians. The reason for this is that the entities might need to constantly share information with each other at the same time but the geographical distance constraints them (Radiol, 2012). Also, the physicians with the intention of applying VCS to remain in touch with patients are viable. Modeling Application Cross Reference (This section is required for all Modeling Applications) The VCS system works like a distributed operating system. The network has an overhead known as the gateway (Radiol, 2012). The rest of the infrastructures such as the PCs and phones are connected to the gateway for easier conferencing by participants. High-Level Risks (This section required for New Applications and Significant Changes only) The high risks of the project are built on the fact that it is a new undertaking. It will require enormous resources. Hence, only success can justify by it not a failure (Radiol, 2012). SYSTEMS ENGINEERING AND INTEGRATION 4 Outstanding Issues The outstanding issue is that the system calls for a collection of users. It would be difficult for individuals that want to apply it independently to utilize it without other users (Radiol, 2012). Hence, it is intrinsically a collective system. Assumptions (This section is required for New Applications and Significant Changes only) The assumption is that medical practitioners are ready for the system. Since, the group has always wanted to share medicinal knowledge collectively (Dinesen, 2016). Moreover, it is assumed that physicians might find it worthy to communicate to different patients with the same illness at the same time. Constraints (This section is required for New Applications and Significant Changes only) The constraints have to do with the gathering of resources to fulfill the project. Also, it might take a considerable time to acquire authoritative mandate to carry on with the project (Synn, 2011). Dependencies (This section is required for New Applications and Significant Changes only) The project relies on the availability of resources. Also, it requires permission from relevant authorities (Dinesen, 2016). Furthermore, all stakeholders with essential knowledge concerning the system will have to coordinate. SYSTEMS ENGINEERING AND INTEGRATION Critical Success Factors (This section is required for New Applications and Significant Changes only) The critical success factor will rely on the existing knowledge of such systems. Correspondingly, the availability of all the required resources will determine the success rate (Radiol, 2012). Policy Impacts The project might lead to implementing of policies that encourage technological inventions for telemedicine. In this way, the field will keep on developing (Radiol, 2012). Moreover, it will perpetually accommodate other innovations Procedure Impacts (This section is required for New Applications and Significant Changes only) The project has to deal with procedural impacts. Developers have to consult the relevant authorities (Dinesen, 2016). Also, the procedure should involve seeking appropriate sources of capitals for completion of the project. Legal Impacts (This section is required for New Applications and Significant Changes only) The project has to operate based on the stipulated legal guidelines. Furthermore, any adverse effects of the project should be clearly stipulated (Dinesen, 2016). Hence, the stakeholders will have an excellent opportunity to start and complete it. 5 SYSTEMS ENGINEERING AND INTEGRATION 6 Controls Impacts (This section is required for New Applications and Significant Changes only) The project needs coordination among resource providers. It requires the availability of relevant authorities and other stakeholders (Radiol, 2012). Thus, it is vital to have apparent channels of communication. Training and Rollout (This section is required for New Applications and Significant Changes only) The project will have initial training of the stakeholders to fathom their specific input. It will enable the feasibility of the project (Radiol, 2012). Afterward, it will roll out on the set date of initiation. Notes and Information The project is one of the finest innovations of the 21st century. Once it is completed it will contribute to easier undertakings in telemedicine. Thus, it requires sufficient and essential support. SYSTEMS ENGINEERING AND INTEGRATION References Dinesen, M. S. (2016, March). Personalized Telehealth in the Future: A Global Research Agenda.

Project: Date(s): Prepared by: Document status: __ Draft __ Proposed __ Validated __ Approved 1. Introduction This document contains the system requirements for project name. These requirements have been derived from several sources, including brief listing of most important sources. 1.1 Purpose of This Document This document is intended to guide development of project name. It will go through several stages during the course of the project: Draft: The first version, or draft version, is compiled after requirements have been discovered, recorded, classified, and prioritized. Proposed: The draft document is then proposed as a potential requirements specification for the project. The proposed document should be reviewed by several parties, who may comment on any requirements and any priorities, either to agree, to disagree, or to identify missing requirements. Readers include endusers, developers, project managers, and any other stakeholders. The document may be amended and reproposed several times before moving to the next stage. Validated: Once the various stakeholders have agreed to the requirements in the document, it is considered validated. Approved: The validated document is accepted by representatives of each party of stakeholders as an appropriate statement of requirements for the project. The developers then use the requirements document as a guide to implementation and to check the progress of the project as it develops. 1.2 How to Use This Document We expect that this document will be used by people with different skill sets. This section explains which parts of this document should be reviewed by various types of readers. Types of Reader In this section, list the different types of reader this document is aimed at. For example, Flash programmers, graphic designers, end-users, project managers, etc. For each type of reader, clearly state which sections are most pertinent to them, and which may be safely skipped. Technical Background Required Describe here the technical background needed to understand the document in general, and any particular expertise or understanding that is needed for specific sections. Overview Sections List here the sections that should be read by someone who only wishes to gain an overall understanding of the project, or which should be read first before technical requirements are reviewed. Reader-Specific Sections In this section, name any parts of the document which are intended only for one or another of the reader types identified above, and which may therefore be skipped by other readers. Section Order Dependencies If readers will need to read certain sections in a specific order, note those sections here. Also point out any sections that may be read independently with no loss of understanding. 1.3 Scope of the Product Include a brief narrative here which describes the product as you intend it to be realized. Use this section to define boundaries and set expectations. 1.4 Business Case for the Product Why is this product required? How will it contribute to the goals of your institution? This section can be used when requirements are being negotiated, to assess whether a particular change is a good idea. This section also helps readers understand why certain requirements have been included. 1.5 Overview of the Requirements Document If your project is small to medium in size, include a summary of the requirements here. This may be a numbered list of the most important requirements. The purpose of this section is to give the reader a general understanding of the requirements and focus attention on the most critical ones. This section may also help point readers to the specific requirements that are of particular interest to them. 2. General Description This section will give the reader an overview of the project, including why it was conceived, what it will do when complete, and the types of people we expect will use it. We also list constraints that were faced during development and assumptions we made about how we would proceed. This section contains a nontechnical description of the project, usually in narrative form, which may serve to acquaint new readers with the purpose of the project. It also sets the stage for the specific requirement listing which follows. 2.1 Product Perspective Why have you chosen to develop this product? What need does it serve? Who are the primary stakeholders, who is developing the project, and who will benefit from the finished product? 2.2 Product Functions What does your product do? What activities can users perform while using it? List the main functions that you will build into your product here. 2.3 User Characteristics Who do you expect to use your finished product, and why? What is their technical background, their training or education, their motivation to use it? What obstacles might they encounter, and what specialized skills will they need? 2.4 General Constraints Did you work under any constraints such as platform or development environment? Did you have to make your product compatible with any existing software or other products currently in use? 2.5 Assumptions and Dependencies In this section, list any assumptions you made about your project (for example, did you assume that the finished product would need to be delivered over the internet?). If your project depends on any particular technical infrastructure, or requires administrators or others with specific skills, note that here. 2.6 Maintenance and Support Concept How will the system be maintained and supported during its life-cycle? The maintenance and support concept generally includes the levels of maintenance, repair policies, organizational responsibilities, maintenance support elements, effectiveness requirements, and environment. Refer to pages 76-81 in the textbook. 2.7 Functional Analysis and Allocation Provide a functional flow block diagram of the system's top-level functions. Refer to pages 86-93 in the textbook. 2.8 Cost Analysis How much will the entire implemented system cost? Provide a breakdown of the estimated cost for each major component and the total cost for your entire system. 3. Specific Requirements This section of the document lists specific requirements for name of project. Requirements are divided into the following major sections: System and Integration requirements: These are detailed specifications describing the functions the system must be capable of doing. Operational requirements: These are detailed non-functional requirements describing other desired attributes of the overall system and how the system will run and communicate with operations personnel. User Interface requirements: These are requirements about the user interface, which may be expressed as a list, as a narrative, or as images of screen mock-ups. 3.1 System and Integration Requirements List detailed system requirements here. These are your functional (or technical) Type A system-level requirements. If your system is large, you may wish to break this into several subsections. Include dependencies on existing systems. 3.2 Operational Requirements List detailed operational requirements here. These are your non-functional requirements. Do not state how these requirements will be satisfied. For example, in the Reliability section, answer the question, “How reliable must the system be”? Do not state what steps will be taken to provide reliability. You should include the following types of requirements below: 3.2.1 Performance List performance requirements here. Include response time for queries and updates, throughput, expected rate of user activity (for example, number of transactions per hour, day, or month, or cyclical periods), and specific performance requirements related to a specific functional requirement which should be listed with that functional requirement. 3.2.2 Physical Characteristics List physical requirements here (e.g., size?, weight?, speed?, etc.) 3.2.3 Effectiveness/Reliability List effectiveness and reliability requirements here. Reliability is the probability that the system processes work correctly and completely without being aborted. State the following in this section: 1. State the damage that can result from failure of this system - indicate the criticality of the software, such as: (a) Loss of human life (b) Complete or partial loss of the ability to perform a mission-critical function (c) Loss of revenue (d) Loss of employee productivity 2. What is the minimum acceptable level of reliability? 3. State required reliability: (a) Mean-Time-Between-Failure (MTBF) is the number of time units the system is operable before the first failure occurs. (b) Mean-Time-To-Failure (MTTF) is the number of time units before the system is operable divided by the number of failures during the time period. (c) Mean-Time-To-Repair (MTTR) is the number of time units required to perform system repair divided by the number of repairs during the time period. 3.2.4 Availability List availability requirements here. System availability is the time when the application must be available for use. Required system availability is used in determining when maintenance may be performed. State the period during which the application must be available to users. For example, “The application must be available to users Monday through Friday between the hours of 6:30 a.m. and 5:30 p.m. MST. If the application must be available to users in more than one time zone, state the earliest start time and the latest stop time. Consider daylight savings time, too. Include use peak times. These are times when system unavailability is least acceptable. 3.2.5 Recoverability List recoverability requirements here. Recoverability is the ability to restore function and data in the event of a failure. Answer the following questions in this section: 1. In the event the application is unavailable to users (down) because of a system failure, how soon after the failure is detected must function be restored? 2. In the event the database is corrupted, to what level of currency must it be restored? For example “The database must be capable of being restored to its condition of no more than 1 hour before the corruption occurred”. 3. If the processing site (hardware, data, and onsite backup) is destroyed, how soon must the application be able to be restored? 4. Backup: Identify backup requirements for ensuring the continued achievement of system functions. 5. Fallback: Identify fallback techniques for ensuring the continued satisfaction of the specific requirements of the system. Fallback indicates the use of another system to satisfy the system requirements. For example, the fallback techniques for an automated system might be manual manipulation and recording of data. 6. Degraded Modes of Operation: State priorities for restoring the essential functional processing steps in the event that full processing capability is not available. 3.2.6 Maintainability List maintainability requirements here (e.g., reusability?, extensibility?, etc.) 3.2.7 Usability List usability (human factors) requirements here. These are requirements written from the point of view of end users (e.g., what is the ease with which the system can be learned or used?). 3.2.8 Supportability List supportability requirements here (e.g., how will hardware and/or software components of the system be easily modified or maintained to accommodate typical usage or change scenarios?) 3.2.9 Portability/Mobility List portability/mobility requirements here. Provide a description of the hardware and software platforms needed to support the system. 3.2.10 Sustainability List sustainability requirements here (e.g., has a long life?, is repairable?, efficiently incorporates environmentally friendly materials?). 3.2.11 Security and Privacy List security requirements here. This section describes the need to control access to the data. This includes controlling who may view and alter application data. Use the following criteria: 1. State the consequences of the following breaches of security: (a) Loss or corruption of data (b) Disclosure of sensitive information (c) Disclosure of privileged/privacy information about individuals (d) Corruption of software or introduction of malware such as viruses. 2. State the type(s) of security required. Include the need for the following as appropriate: (a) Physical security (b) Access by user role or types (c) State access control requirements by data attribute. For example, one group of users has permission to view an attribute but not update it while another group of users has permissions to update or view it. (d) State access requirements based on system function. For example, if there is a need to grant access to certain system functions to one group of users, but not to another. For example, "The system shall make Function X available to the System Administrator only." (e) State if there is ...
