Requirements Flashcards
Requirements
A requirement is a statement about an intended product that specifies what it is expected to
do or how it will perform.
Functional requirements
Defines a function of a system or its component, where a function is described as a specification of behavior between outputs and inputs.
Nonfunctional requirements
Is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviors.
Data requirements
Data requirements capture the type, volatility, size/amount, persistence, accuracy, and value of the required data.
Environmental requirements
Environmental requirements, or context of use, refer to the circumstances in which the interactive product will operate.
User characteristics
User characteristics capture the key attributes of the intended user group, such as the users’ abilities and skills, and depending on the product, also their educational background, preferences, personal circumstances, physical or mental disabilities, and so on.
Usability goals and user experience goals
The usability goals of the product are agreed upon early in the development process and are used to track progress as development proceeds.
Cultural probes
Cultural probes (or design probes) is a technique used to inspire ideas in a design process.
Design probes
Design Probes refers to a self-documentation method where users observe and reflect on their everyday lives and experiences, followed by documenting them.
Technology probes
Technology probes are simple, flexible, adaptable technologies with three interdisciplinary goals: the social science goal of understanding the needs and desires of users in a real-world setting, the engineering goal of field-testing the technology, and the design goal of inspiring users and researchers to think about new technologies.
Provocative probes
Provocative probes are technology probes designed to challenge existing norms and attitudes in order to provoke discussion.
Concept principle
The context principle emphasizes the importance of going to the user, wherever they are, and seeing what they do as they do it.
Partnership principle
The partnership principle creates a collaborative context in which the user and interviewer can explore the user’s life together, on an equal footing.
Interpretation
Interpretation turns the observations into a form that can be the basis of a design hypothesis or idea.
Focus
Focus is established to guide the interview set up and tells the interviewer what they need to pay attention to among all of the details that will be unearthed.
