Quality Control And Quality Assurance Flashcards
(17 cards)
Quality Control
Ensure a product has met standards. Various tools are used to ensure parts have dimensional accuracy and are within the tolerances.
Quality assurance
Is process oriented and focuses on defect prevention. It involves measurement of variables, comparisons with specifications, consistent monitoring of processes, using feedback loops to prevent errors. Waste reduction, accurate manufacturing, applying tolerances.
Is a procedure or system which is followed in order to achieve the desired level of quality.
QA systems
Total quality management, drum, six sigma, critical path analysis.
Flowcharts
Are a simple way to plan a sequence of manufacturing events. They highlight critical control points and allow feedback.
Gantt charts
Used in project management
Kaizen
In Japanese means change for god and is the guiding principle behind lean manufacturing. It aims to improve efficiency and eliminating waste in all areas of production. Kaizen relies on: employee collaboration, practical improvement and evaluation and innovation.
Total Quality Management (TQM)
Is a customer focused process centred strategy. Key features include: integrate strategies and systems, employee involvement, communication, constant feedback, continuous improvement.
Scrum
Is a quality driven, agile framework for managing product development and problem solving. Scrum is initiated by a product owner and a product backlog. The scrum master leads the scrum team in a series of sprints (short focused tasks delivered by the team). Scrum uses different types of sprint meetings and lists to ensure everything is kept on track.
Sprint backlog
Is a list of products to produce in the next sprint
Scrum board
Contains a list of tasks for each team member and tracks their process.
Sprint planning
Used to set up sprint parameters.
Daily stand ups
Used to check everything is going to plan
Sprint review
Used to deliver the results and get feedback.
Sprint retrospective
Used to reflect of what could be improved.
Six sigma
Created by Motorola in 1986, six sigma aims to improve processes and management performance. Six sigma refers to the number of allowable defects, 3.4 per million DPM. Identifying and removing the main causes of errors and improves efficiency, productivity, limits waste.
Process planning
Businesses use various ethos of planning and charting projects including project evaluation and revenue techniques (PERT) and critical path analysis.
Critical path analysis
Is a six step method used to plan sequential activities, showing them as nodes, usually boxes, joined with arrows with each box including details of the duration of the task.
