ISDS 3115 STUDY EXAMS ANSWERS AND
QUESTIONS SET A+
Upper Control Limit (UCL) formula - ✔✔x + zσxˉ
✔✔Lower Control Limit (LCL) formula - ✔✔x - zσxˉ
✔✔X = - ✔✔mean of the sample means
✔✔Z = - ✔✔number of normal standard deviations
✔✔σxˉ - ✔✔standard deviation of the sample means
✔✔n = - ✔✔sample size
✔✔R = - ✔✔average range of samples
✔✔What is an operations manager's objective? - ✔✔to build a total quality management
(TQM) system that identifies and meets customer needs
✔✔What is TQM? - ✔✔Total Quality Management
✔✔Quality definition - ✔✔The totality of features and characteristics of a product or
service that bears on its ability to satisfy stated or implied needs
✔✔Tangible - ✔✔easily measured costs (utilities, labor, materials, taxes)
✔✔Intangible - ✔✔not as easy to quantify (measure)
✔✔costs of quality - ✔✔prevention costs, appraisal costs, internal failure costs, and
external failure costs
✔✔prevention costs - ✔✔reducing the potential for defects
, ✔✔appraisal costs - ✔✔evaluating products, parts, and services
✔✔internal failure costs - ✔✔producing defective parts or services before delivery
✔✔external failure costs - ✔✔defects discovered after delivery
✔✔concepts of TQM - ✔✔continuous improvement, six sigma, just in time, knowledge
of TQM tools
✔✔six sigma meaning (1) - ✔✔statistical: describes a process, product, or service with
an extremely high capability
✔✔six sigma meaning (2) - ✔✔a program designed to reduce defects, lower costs, save
time, and improve customer satisfaction
✔✔TQM tools - ✔✔generating ideas, organizing data, and identifying problems
✔✔Tools for Generating Ideas - ✔✔check sheet, scatter diagram, cause and effect
diagram
✔✔Tools for organizing data - ✔✔pareto chart and flowchart (process diagram),
✔✔tools for identifying problems - ✔✔histogram, statistical (diagram), and process
control chart
✔✔country location facors - ✔✔political risks, laws, culture & economic issues,
availability, rates & risks
✔✔regional location factors - ✔✔labor and utilities availability and costs. proximity and
attractiveness
✔✔site location decisions - ✔✔transportation, proximity, size and cost, and zoning
restrictions
✔✔proximity to markets - ✔✔very important to services. JIT systems or high
transportation costs may make it important to manufacturers
✔✔proximity to suppliers - ✔✔perishable goods, high transportation costs, bulky
products
✔✔process focused - ✔✔organized by function, flexible, low volume (patient movement
in hospital)
