Process innovation is most successful in organizations that view their systems as a set
of functional areas vying for limited resources.
Dependent demand items are typically products for use by the final customer.
For a given process, the process capability ratio is not related to its specification limits.
Short-midrange forecasts tend to use quantitative models that forecast demand based on
historical demand.
One benefit of small lot production is that workers demonstrate fewer tendencies to let
poor quality pass.
Scheduling using the theory of constraints (TOC) requires that process batch sizes and
transfer batch sizes always match.
The objective function is a linear relationship that either minimizes or maximizes some
value.
Companies with a quality focus generally give their employees the authority to make
decisions that will improve quality.
Worldwide, extended producer responsibility (EPR) is becoming an important factor
influencing product design for personal computers and some household appliances.
A process flowchart is a useful tool for analyzing a process because it often highlights
nonproductive activities.
Variable control charts are used to monitor measurable characteristics of a process’s
outputs rather than descriptive characteristics.
If the average service rate is smaller than the average arrival rate an infinitely large
waiting line (queue) will form.
For most industrialized countries, the difference between a company’s success and
failure is dependent on the capability of its human resources.
Statistical process control can prevent poor quality before it occurs if a pattern is
evident in the plotted points.
When demand fluctuations are extreme using overtime and undertime is a feasible
strategy for adjusting capacity.
