HCI - Chapter 6

waterfall model

Each phase in this model must be completed before the next phase can begin and there is no overlapping in the phases.

requirements

In this cycle, designer and customer try capture what the system is expected to provide.

ISO usability standard 9241

It adopts traditional usability categories of effectiveness, efficiency and satisfaction of the software.

ISO/IEC 25000

It comprises a series of standards based on ISO/IEC 9126 and ISO/IEC 14598 whose main objective is to guide the development of software products through the specification of quality requirements and the evaluation quality characteristics.

usability engineering

It demands that specific usability measures be made explicit as requirements.

Structure-oriented DR

It emphasizes post hoc structuring of considered design alternatives.

architectural design

It has high-level description of how the system will provide the services required

detailed design

It has refinement of architectural components and interrelations to identify modules to be implemented .

Portability

It is a degree of effectiveness and efficiency with which a system, product or component can be transferred from one hardware, software or other operational or usage environment to another.

Usability

It is a degree to which a product or system can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.

Security

It is a degree to which a product or system protects information and data so that persons or other products or systems have the degree of data access.

Compatibility

It is a degree to which a product, system or component can exchange information with other products, systems or components, and/or perform its required functions.

Reliability

It is a degree to which a system, product or component performs specified functions under specified conditions for a specified period of time.

storyboard

It is a graphic organizer that provides the viewer with a high-level view of a project.

validation

It is about designing the right product.

Design space analysis (DSA)

It is aimed at helping software designers reason about design (individually and in groups) and to produce a representation.

Issue-based information system (IBIS)

It is an argumentation-based approach to clarifying wicked problems—complex, ill-defined problems that involve multiple stakeholders.

Psychological design rationale

It is build to support task-artifact cycle in which user tasks are affected by the systems they use.

Design rationale

It is information that explains why a computer system is the way it is.

software engineering

It is the discipline for understanding the software design process, or life cycle.

formality gap

It is the validation that will always rely to some extent on subjective means of proof.

verification

It it about designing the product right.

Iterative design

It overcomes inherent problems of incomplete requirements

Process-oriented DR

It preserves order of deliberation and decision-making

QOC - criteria

These are the means to assess the options in order to make a choice.

QOC - options

These provide alternative solutions to the question.

QOC - questions

These represent major issues of a design

Maintainability

This characteristic represents the degree of effectiveness and efficiency with which a product or system can be modified to improve it, correct it or adapt it to changes in environment, and in requirements.

Functional suitability

This characteristic represents the degree to which a product or system provides functions that meet stated and implied needs when used under specified conditions.

Performance efficiency

This characteristic represents the performance relative to the amount of resources used under stated conditions.

ISO 25010

This quality model determines which quality characteristics will be taken into account when evaluating the properties of a software product.

management and contractual issues

This should have in commercial and legal contexts.

Prototypes

simulate or animate some features of intended system
