Qualitative Forecasting Techniques
In forecasting, an approach that is based on intuitive or
judgmental evaluation. It is used generally when data are
scarce, not available, or no longer relevant. Common types of
qualitative techniques include: personal insight, sales force
estimates, panel consensus, market research, visionary
forecasting, and the Delphi method. Examples include
developing long-range projections and new product
introduction.
Quality
Conformance to requirements or fitness for use. Quality
can be defined through five principal approaches:
-
Transcendent quality is an ideal, a
condition of excellence
-
Product-based quality is based on a product
attribute
-
User-based quality is fitness for use
-
Manufacturing-based quality is conformance
to requirements
-
Value-based quality is the degree of
excellence at an acceptable price. Also,
quality has two major components:
-
quality of conformance—quality is defined
by the absence of defects, and
-
quality of design—quality is measured by
the degree of customer satisfaction with
a product’s characteristics and
features.

Quality Circle
In quality management, a small group of people who normally
work as a unit and meet frequently to uncover and solve
problems concerning the quality of items produced, process
capability, or process control.
Quality control
The management function that attempts to ensure that the
foods or services manufactured or purchased meet the product
or service specifications
Quality Function Deployment (QFD)
A structured method for translating user requirements into
detailed design specifications using a continual stream of
‘what-how’ matrices.
QFD links the needs of the customer (end user) with design,
development, engineering, manufacturing, and service
functions. It helps organizations seek out both spoken and
unspoken needs, translate these into actions and designs, and
focus various business functions toward achieving this common
goal
Quantitative Forecasting Techniques
An approach to forecasting where historical demand
data is used to project future demand. Extrinsic and intrinsic
techniques are typically used
Quantity Based Order System
See Fixed Reorder Quantity Inventory Model
Quarantine
In quality management, the setting aside of items
from availability for use or sale until all required quality
tests
have been performed and conformance certified
