Requirements Specification Techniques:
After requirements and analysis, the 3rd phase of the Lifecycle of Requirements Engineering is known as requirements specifications or requirements documentation. In fact, the user and system requirements are written down into a document through this process and the creation of this document with the corresponding level of details is the basic goal of this process. A total description of the behavior of the proposed system or software should be included in this document. It must also contain the functional aspects of the software as well as the relevant security constraints, its performance and interface itself. These aspects of the system are usually described through the non-functional requirements. In place of mathematical specifications or graphical notations known as formal methods, informal languages such as flow diagrams and natural language are used to……….
Elicitation of requirements specification: For the purpose of the creation of a functional model specified with use cases, the process of identification and formalization of the requirements of a software is known as elicitation. Studying, observing, and analyzing the current processes, market research, interviews, questionnaires and all the relevant information are some of the basic approaches used to elicit the requirements of any …………
Use Cases: By not depicting the exact methodology of making things happen, use cases, instead, specify the expected behavior of the system. For any new software system under development, a UML use case diagram is the basic form of system requirements. Use cases once specified can be denoted through both visual and textual representation. The ability to design a system from end user’s perspective is one of the basic…….
User Stories: Brief descriptions written in natural language by users, focusing on what users need, are known as user stories. User stories have nothing to do with what the system should deliver like in the traditional requirement capturing cases. User stories not only help solve customers’ operational problems but also add…….
Use cases vs User stories: While keeping in mind the main and important components in both scrum and extreme programming methodologies, we can easily conclude that user stories comprise….
Data Flow Diagram: In order to define the scope of the project, the data flow diagram is designed earlier in requirements elicitation process of system development life cycle’s phase of analysis. This process is divided into various smaller and lower level DFD processes in case further details are required to be shown within any particular process…
Requirements Specification for student registration: Students, faculty members and employees of educational institutions require an online registration system in order to process their admission and registration applications and be able to search and select courses online. A prototype of the software system is designed and developed based on the usability study results which addressed the limitations of……….
User Frustration (Definition & Brief Introduction): One of the most persistent and pervasive issues with computing and information technology is user frustration. A great deal of work and research has been carried out to understand the origins of customer emotions, end-user frustration and its relevant affects for providing additional insight into the matter. Users get frustrated all the time and delete various software applications. Users tap on buttons and still nothing happens at all. They process the opening of a new page by clicking but the time for loading the page is frustratingly slow. User frustration primarily takes place when they are unable to overcome a certain obstacle………
Reasons for Users’ Frustration with Modern Applications:
If the usual frustration patterns are found and fixed, then it can result in the satisfaction and loyalty of users, but the identification of user frustration is an uphill task. Here the most common user frustration indicators are explained in order to help satisfy users.
Some quite common User Frustration indicators include Rage Scrolling, Rage Taps, Random Scrolling, Unresponsive Gestures, Direct Uninstallation, Aborted Events and Direct Back-tapping etc. Rage taps take place when users click on different elements but still nothing happens at all because most probably there………..
Methods for determination and reduction of User Frustrations: It would rather be better and more sensible to offer users a certain degree of freedom and not overwhelm them with too many choices and simplify their experience by dividing processes into smaller steps. Search filtering….
Methods for reduction of User Frustrations among Disabled Population: Websites and software applications should be designed to make a universal access possible, including for users with visual, auditory, motor, and cognitive disabilities. Providing the Web with greater accessibility for disabled users…………………………
