Qualitative data

Data measured on a nominal scale. Also called discrete data. See also data types.

Qualitative market research

Research designed to guide organizations in their decision-making.

Qualitative research

A study of how people interpret their experiences in relation to the world around them. See also quantitative research.

See biography, case study, ethnography, focus group, grounded theory, interview, non-participant observation, participant observation, phenomenology, pilot testing, quantitative research methods, questionnaire, sample, structured interview, survey, unstructured interview.

Qualitative risk analysis

Performing a qualitative assessment of risks and conditions to prioritize their effects on project objectives. It involves assessing the probability and impact of project risks and using methods such as the probability and impact matrix to classify risks into categories of high, moderate, and low for prioritized risk response planning.

Qualitative variable

Quality

The extent to which a product or service meets customer requirements and is fit for use.

Quality assurance (QA)

Planned or systematic actions necessary to provide adequate confidence that a product or service is of the type and quality that the customer needs and expects, and that management and technical planning and controls are adequate to establish correct technical requirements for design and manufacturing. See also software quality assurance.

Quality Assurance Plan

A project document that ensures that the system satisfies contractual agreements, meets or exceeds quality standards, and complies with approved systems development life cycle (SDLC) processes. The plan describes the actual QA activities (audits, testing, problem reporting, and corrective action) that will be integrated with the project plan and schedule. The level of detail contained within is consistent with the complexity, size, intended use, mission criticality, and cost of failure of the system development effort. TEMPLATE GUIDE

Quality audit

A systematic and independent examination to determine whether quality activities and related results comply with planned arrangements, and whether these arrangements are implemented effectively and are suitable to achieve objectives. Also, a structured review of quality management activities to identify lessons learned and improve performance.

Quality control (QC)

Quality system

The organizational structure, procedures, processes, resources, and responsibilities for implementing quality management.

Quantitative data

Data measured on an interval, ordinal, or rational scale. See also data types.

Quantitative market research

Research that focuses on the incidence and statistical relationship of variables, typically using structured questionnaires and large samples.

Quantitative research

Research that measures and determines the relationship between one thing (the independent variable) and another (the dependent variable). See also qualitative research.

Quantitative research methods

See qualitative research methods, survey.

Quantitative risk analysis

Measuring the probability and consequences of risks and estimating their implications for project objectives.

Quantitative variable

Variables that already exist as numbers; for example, age and weight. See also qualitative variable, variable types.
