Internal oriented quality | The characteristics of the product are specific and can be measured |
external oriented quality | quality as defined by the customer, therefore, making it subjective. |
reliability | the ability to perform the promised service dependably and accurately. |
responsiveness | the willingness to help customers and provide prompt service. |
assurance | the knowledge and curtesy of employees and their ability to convey trust and confidence. |
reliability | the length of time a product will function before it fails |
conformance | the degree to which a product design and operating characteristics match pre-established standards. |
failure cost | costs that are incurred whenever any product or component of a product fails to meet requirements. |
internal failure cost | those associated with defects found before the product reaches the customer |
external failure cost | incurred after a product has reached the customer |
appraisal costs | the costs incurred to measure quality, assess customer satisfaction, and inspect and test products. |
prevention costs | incurred from activities designed to prevent defects from occurring. |
Statistical Process Control (SPC) | used to determine when a process that produces goods is getting close to producing an unacceptable number of errors. |
W. Edward Deming | created 14 points on quality management and SPC. believed in continuous improvement. believed that the system is what makes mistakes and management is responsible, not the employees. Modified the plan-do-check-act into the plan-do-study-analyze |
Joseph Juran | defined quality as 'fitness for use' and should be defined by the customer. 3 elements - quality planning, quality control, and quality improvement. |
Philip Crosby | 'Do it Right the First Time' Author of 'Quality is Free' Emphasize the importance of considering all costs of quality. Is responsible for the concepts of zero as a measurable object. |
Genichi Taguchi | his philosophy is based on robust designs. perfected experiements to create higher quality products. beleived that quality should be built into the product. |
Robust Design | designs that guarantee high quality regardless of variations that may occur during the processes that produce the product. |
Kaoru Ishikawa | created the 'fishbone chart' or cause and effect charts. also helped create quality circles. believed that teamwork is important for quality leadership. |
Total Quality Management | determines what their customers needs and expectations. |
Standardization | developing a preset procedure for performing an activity or job. |
documentation | the act of putting that procedure into writing |

Scatter Plot | displays data as a relationship between two variables. |
Pareto Chart | represents data values in a descending order to visualize the most frequent occurrences. |
Control charts | graphical depictions of process output where the raw data is plotted in real time within upper and lower control limits. |
six sigma | a set of management techniques intended to improve business processes by greatly reducing the probably that ab error will occur. |
define | a project charter is used to define a problem or improvement opportunity. |
value stream mapping | provides an overview of the entire process from start to finish, also includes customer feedback. |
measure | each step is assessed to determine the ability to meet customer specification in a capability analysis. |
analysis | main objective is to determine the root cause of variation in the process that results in failures or defects. |
improve | changes are made to the process by addressing the root problems found in the analysis phase. |
control | maintaining and standardizing the improved performance. |
