TAMU ISEN 350 Exam 1Your company receives shipments of 200 Printed Circuit Boards (PCBs) from a
supplier. You are responsible for testing the shipments using a sampling plan(n=20,
c=2) which has been agreed upon with the supplier. If a shipment is rejected it is
returned to the supplier, who must incur all associated costs. The number of
nonconforming PCBs in a shipment follows a binomial distribution. If a shipment has 4%
nonconforming PCBs, what is the probability the supplier will have to incur all costs? -
answeron TI-84 enter "1-binomcdf(20,0.04,2)" and should get .0439

Quality means _______ or ______ - answerfitness for use or conformance
______ is inversely proportional to variability - answerQuality
Acceptance sampling - answerused to determine whether to accept or reject a
production lot of material. It is a common quality control technique used in industry.
, Binomial distribution
_________ is the reduction of variability in processes and products. - answerQuality
Improvement
What is an OC Curve? - answer
Design of Experiments - answerDOE is to discover the key input variables or factors
influencing the quality characteristics of interest in a process or product, through
systematic experimentation.
Genichi Taguchi - answerTaguchi developed and popularized robust design concept on
top of DOE methods (known as Taguchi Methods).
Critical to Quality - answerCritical-to-quality (CTQ): Elements of a product or service
that jointly describe what the user or consumer thinks of as quality. These can be
physical, sensory, or time oriented. Overall, these elements can be thought of as the
elements that make the quality of a good or service what it is; if something is wrong with
a CTQ element, then the overall quality reflects.
Design for Six Sigma (DFSS) - answerDesign for 6 Sigma (DFSS): an approach for
taking the variability reduction and process improvement philosophy of Six Sigma
upstream from manufacturing or production into the design process. It is a structure and
methodology for efficient commercialization of technology that results in new products.
Following this approach, in the design phase the manufacturability, cost, and
performance are determined and improved if possible, with predicted outlook. There is a
focus on customer requirements while simultaneously keeping process capability in
mind
Key Process Input Variables (KPIV) - answerKey Process Input Variables (KPIV): is a
process input that provides a significant impact on the output variation of a process. The
KPIV is usually (at least tentatively) defined in the "Define" phase of the DMAIC process
and are listed in the "Measure" step. I understand these as the main variables to
process inputs that are vital to the quality, manufacturing, and use of products or
services. Variations to the KPIV alter the overall quality of the process or service.
Key Process Output Variables (KPOV) - answerKey Process Output Variables (KPOV):
factors that results as output from a process or some objects such as parts, assemblies
or entire systems. Variations in KPOV can result in a significant impact on the
performance, efficiency, manufacturability, reliability or assembly of the system or
objects being monitored. Similar to KPIV, I understand these similar to the CTQ, except
less physical attributes and more output variables.
DMAIC - answerDMAIC: s a structured problem-solving procedure widely used in
quality and process improvement. DMAIC stands for Define, Measure, Analyze,
Improve, and Control. It is also often associated with Six Sigma activities, although not
