EXAMPLE: [Downloads are easy to access] Students shall have the option to download course materials when viewing a course lesson or the course overview. Usability — how easily the user is able to learn, operate, prepare inputs and interpret outputs through interaction with a software system. ELICITATION: Portability requirements address the user concern for how easy it is to transport the system. DEFINITION: Verifiability is the extent to which tests, analysis, and demonstrations are needed to prove that the software system will function as intended. ELICITATION: Reusability requirements address the user concern for converting the software for use in another system. The origins of contemporary reliability engineering can be traced to World War II. These statements are treated as a problem that must be solved. In order to apply a user-focused approach, it is necessary to understand who the user is. Reliability is the wellspring for the other RAM system attributes of availability and maintainability. This is the ultimate nonfunctional requirements course! Thus in this study, they … 1. They specify the quality attribute of the software. REVISION, or changing source code or data that drive the system. DEFINITION: Survivability is the extent to which the software system continues to function and recovers in the presence of a system failure. The user perceives the system as a set of programmed language statements. The transition group includes the following nonfunctional categories: Installability — how easily the system can be installed, uninstalled, or reinstalled into a target environment. DEFINITION: Safety is the degree to which a software system prevents harm to people or damage to the environment in the intended context of use. That is, the user is concerned with aspects such as packaging, transport, and compatibility with other systems. DEFINITION: Reliability is the extent to which the software system consistently performs the specified functions without failure. Non-Functional Requirements deal with issues like scalability, maintainability, performance, portability, security, reliability, and many more. DEFINITION: Installability is the ease with which a software system can be installed, uninstalled, or reinstalled into a target environment. In this paper, we discuss several problems with the MI, and we identify a number of requirements to be fulfilled by a maintainability model to be usable in practice. maintainability of a system. Based on the user-focused approach, nonfunctional categories can be classified into three requirement groups: Operation requirements define how well the software system performs for use by the user. Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Users who come in contact with the software system by managing the upkeep of the system are generally most concerned with transition requirements. Non-Functional requirements Maintainability Measures (1) •Measures ability to make changes quickly and cost effectively • Extension with new functionality • Deleting unwanted capabilities • Adaptation to new operating environments (portability) • Restructuring (rationalizing, modularizing, optimizing, creating DEFINITION: Maintainability is the ease with which faults in a software system can be found and fixed. Integrity — how well the data are maintained by the software system in terms of accuracy, authenticity, and without corruption. User contact with the software system might occur in the following ways: OPERATION, or using the functionality. EXAMPLE: [Frequently Asked Questions] The functionality for frequently asked questions on the RQ Website overall may be reused on frequently asked questions related specifically to on-demand courses. The categories presented below are detailed in Roxanne Miller’s book ELICITATION: Maintainability requirements address the user concern for how easy it is to upkeep and repair the system. Users who come in contact with the software system by managing the upkeep of the system are generally most concerned with transition requirements. Revision requirements define how efficiently the software system can be corrected or fixed when errors occur, and how easily new features can be added. 1.2.3 Maintainability Maintainability is the ability of an item to be retained in, or restored to, a specified condition when maintenance is performed by personnel having specified skill levels, using prescribed procedures and resources, at each prescribed level of maintenance and … As presented in chapter 4 of The Quest for Software Requirements, the following simplified definition is used in the context of this site: EXAMPLE: [Video load time] All course lesson videos should load in 2 seconds or less. ELICITATION: Reliability requirements address the user concern for the system’s immunity to failure. EXAMPLE: [Probability of Failure on Demand] The RQ Website probability of failure on demand (POFOD) shall be 0.0001 (1 out of 10000 plays) when a student requests to play a course video. EXAMPLE: [Accessible by people who are hard of hearing] All course lessons will provide a text alternative to audio content. Verifiability — the extent to which tests, analysis, and demonstrations are needed to prove that the software system will function as intended. This preview shows page 25 - 27 out of 113 pages. Identification of non-functional requirements- Portability, Reliability, Maintainability – Correctablity & Adaptability, reusability, testability and correctness 6.3.1 Portability A portability requirement is a developer-oriented quality requirement that specifies a required amount of portability. Ensure that minor defects in the application or component are easy to correct. Based on a literature search and r eview of 240 articles, we present and compar e ten eva lua tion methods. 2. When eliciting efficiency requirements, consider needs regarding response time, throughput, process capacity, and storage capacity. Product transition factors− Portability, Reusability, Interoperability. ELICITATION: Survivability requirements address the user concern for the system’s resilience from failure. EXAMPLE: [Course page content] RQ Website course marketing pages shall be editable in Cornerstone. DEFINITION: Flexibility is the ease in which the software can be modified to adapt to different environments, configurations, or user expectations. Product revision factors− Maintainability, Flexibility, Testability. The objectives of Portability testing are to: Partially validate the system (i.e., to determine if it fulfills its portability requirements): Determine if the system can be ported to each of its required environments: Hardware ram and disk space Modifiability — how easily changes to the system can be developed and deployed in an efficient and cost effective manner. When eliciting maintainability requirements, consider aspects such as maintenance performance metrics, maintenance support features, system maintenance features, system complexity, development process, maintenance process cycle, and possible problems. which something can be maintained while in use. Maintainability are the relative costs of fixing, updating, extending, operating and servicing an entity over its lifetime. and new-course announcements delivered right to their inboxes. Simply said, a non-functional requirement is a specification that describes the system’s operation capabilities and constraints that enhance its functionality. This may be quite trivial to many, but it is still an indication of the lack of uniformity. The international standard ISO/IEC 25010:2011 (which we simply call ISO 25010 in this book 1) breaks down software quality into eight characteristics: maintainability, functional suitability, performance efficiency, compatibility, usability, reliability, security, and portability. • What can change?

ELICITATION: Accessibility requirements address the user concern for how easy the system is to use by people with varying capabilities. The operation group subdivides into the following nonfunctional categories: Access Security — how well the system is safeguarded against deliberate and intrusive faults from internal and external sources. Consider the following needs when eliciting availability requirements: downtime impact on the business, partial availability impact on the business, transparent unavailability, and minimizing unavailability. ELICITATION: Interoperability requirements address the user concern for how easy it is to interface with another system. Its purpose is to stream course lesson videos. ELICITATION: Scalability requirements address the user concern for how easy it is to expand or upgrade the system’s capabilities. The system must be analyzed, modified, and tested as problems arise, or the business changes the way it operates. From this point of view, the user is concerned with how well the system operates. Maintainability is how easy it is for a system to be supported, changed, enhanced, and restructured over time. DEFINITION: Accessibility is the extent to which the software system can be used by people with the widest range of capabilities to achieve a specified goal in a specified context of use. An entity with relatively low costs in these areas is considered maintainable whereas an entity with high costs may be considered unmaintainable or "high maintenance."
