What is ERROR PROOFING??
DIVSTRONGThere are five categories of error proofing:/STRONGBR• Fail safe devices BR• Magnification of senses BR• Redundancy BR• Count down BR• Special checking and control devices BRBRSTRONGFail Safe Device methods: /STRONGBR• Interlocking sequences -ensures the next operation cannot start until the previous operation is successfully complete. BR• Alarms and cutoffs – are activated if there are any abnormalities in the process. BR• All Clear Signals- is activated when all remedial steps have been taken. BR• Foolproof work holding devices – ensure that a part can only be located in one position. BR• Limiting mechanisms – are used to ensure that a tool cannot exceed a certain position or amount. BR• Magnification of senses is used to increase the power of human, seeing, hearing, smelling, feeling, tasting and muscle power. Some examples are optical magnification (such as a comparator) and specific viewing aids with pictures and specific accept/reject criteria. BR• Redundancy is the use of additional activities as a quality safeguard. BR• Multiple identity codes -such as bar and color codes are used to prevent mix-ups. BR• Audit review and checking procedures -assure that the plans are being followed. BR• Design of verification – utilizes special designs, such as holes for viewing to determine if the product or process is performing satisfactorily. BR• Multiple test stations – may check a number of attributes such as those occurring on a high-speed production line. BR• Another category is counting down which structures sensing and information procedures to parallel the operating procedures in order to check each step. The most familiar example of the category of error proofing is the launching of a space vehicle. It has also been effectively used in surgical operations and in welding. BR• Special checking and device controls- an example is the computer checking of credit card numbers whereby invalid numbers are rejected and instant feedback provided. BRBRSTRONGThere are five error proofing principles: /STRONGBR• Elimination BR• Replacement BR• Facilitation BR• Detection BR• Mitigation /DIVDIVBRElimination of the possible error occurs when the process or product is redesigned so that the task is no longer required. BR/DIVDIVReplacement is a change to a more reliable process BR/DIVDIVFacilitation occurs when the process is made easier to perform and therefore, more reliable. BR/DIVDIVDetection occurs when the error is found prior to the next operation. BR/DIVDIVMitigation minimizes the effect of the error. BRBRNote: Without stable processes where output can be accurately measured. It would be non-value added to implement this tool at this time. /DIVDIVnbsp;/DIVDIVP class=MsoNormal style=’MARGIN: 0in 0in 0pt; mso-layout-grid-align: none’SPAN lang=EN style=’FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial; mso-fareast-font-family: ‘Times New Roman’; mso-ansi-language: EN; mso-fareast-language: EN-US’Steven Bonacorsi?xml:namespace prefix = o ns = ‘urn:schemas-microsoft-com:office:office’ /o:p/o:p/SPAN/PP class=MsoNormal style=’MARGIN: 0in 0in 0pt; mso-layout-grid-align: none’SPAN lang=EN style=’FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial; mso-fareast-font-family: ‘Times New Roman’; mso-ansi-language: EN; mso-fareast-language: EN-US’www.linkedin.com/in/StevenBonacorsi o:p/o:p/SPAN/PP class=MsoNormal style=’MARGIN: 0in 0in 0pt; mso-layout-grid-align: none’SPAN lang=EN style=’FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial; mso-fareast-font-family: ‘Times New Roman’; mso-ansi-language: EN; mso-fareast-language: EN-US’603-401-7047o:p/o:p/SPAN/PP class=MsoNormal style=’MARGIN: 0in 0in 0pt; mso-layout-grid-align: none’SPAN lang=EN style=’FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial; mso-fareast-font-family: ‘Times New Roman’; mso-ansi-language: EN; mso-fareast-language: EN-US’sbonacorsi@comcast.neto:p/o:p/SPAN/PDIV style=’BORDER-RIGHT: medium none; PADDING-RIGHT: 0in; BORDER-TOP: medium none; PADDING-LEFT: 0in; PADDING-BOTTOM: 1pt; BORDER-LEFT: medium none; PADDING-TOP: 0in; BORDER-BOTTOM: windowtext 3pt dotted; mso-element: para-border-div’P class=MsoNormal style=’BORDER-RIGHT: medium none; PADDING-RIGHT: 0in; BORDER-TOP: medium none; PADDING-LEFT: 0in; PADDING-BOTTOM: 0in; MARGIN: 0in 0in 0pt; BORDER-LEFT: medium none; PADDING-TOP: 0in; BORDER-BOTTOM: medium none; mso-layout-grid-align: none; mso-border-bottom-alt: dotted windowtext 3.0pt; mso-padding-alt: 0in 0in 1.0pt 0in’SPAN lang=EN style=’FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: Arial; mso-fareast-font-family: ‘Times New Roman’; mso-ansi-language: EN; mso-fareast-language: EN-US’A href=’http://www.theaitgroup.com/’SPAN style=’mso-bidi-font-size: 12.0pt’http://www.theaitgroup.com/SPAN/Ao:p/o:p/SPAN/P/DIV/DIVimg src=”http://feeds.feedburner.com/~r/Lean_Six_Sigma/~4/437755890″ height=”1″ width=”1″/
