Six Sigma Tools – IV : Measurement Systems Analysis

Description

INTRODUCTION

This course on Six Sigma Tools – IV : Measurement Systems Analysis is part of the Six Sigma Specialization series that is designed to give an introductory and intermediate level of familiarization of Six Sigma concepts and tools.

Six Sigma is a systematic improvement process leading to process design / redesign. It uses several statistical tools and is widely applicable to any process – be it in manufacturing or functional areas. The benefits of Six Sigma are widely acknowledged in several industries and for several different processes – many industries have saved many millions of dollars

Six Sigma coupled with other processes like lean manufacturing form a lethal combination leading to radical improvements and huge savings of time, effort and money.

An understanding of the principles is essential for all – both in management and technical workforce.

LEARNING OBJECTIVES

This course covers the Six Sigma Tools – IV : Measurement Systems Analysis. 

Measurement system analysis (MSA) determines the amount of variation contributed by the measurement system. It is an objective method to assess the validity of a measurement system and minimize the factors contributing to process variation that is actual stemming from the measurement system.

The objective is to confirm that the measurement system used to collect the data is valid. The following components of measurement error need to be studied and quantified before establishing process capability and making decisions from the data.

The MSA is often a very time consuming component of the project.

Important terms that will be covered –

• Accuracy / Bias – The difference from the true value and the value from the measurement system. Accuracy represents the closeness to a defined target. Precision is different than accuracy and is covered in Gage R&R under Repeatability.
• Resolution / Discrimination
• Linearity
• Stability

Gage R&R (REPRODUCIBILITY – Ability of one appraiser to get the same result and another appraiser or the ability of all appraisers to get the same results AMONG each other; REPEATABILITY – Ability for an appraiser to repeat his/her measurements each time when analyzing the same part, unit, etc.)

We will discuss these topics in this course.  

On completion of this series, the user will have a good knowledge of:

• Tools used in Define stage – Project charter, Thought map, SIPOC, Value Stream Map, Zero Loss studies to identify bottleneck machine / operation (in manufacturing), Cause and Effect matrix, Failure Mode Effect Analysis
• Measuring the process – Measurement System Analysis. This may be more relevant for processes related to manufacturing
• Improvement methods and related statistical tools of Hypothesis testing – Chi squared test, t test, Analysis of variance (ANOVA)
• Control strategies for sustenance of the improvements made by design or redesign of processes

After this series, the participant can appreciate any topic on Six Sigma which are at fundamental or intermediate levels. On completion of the series the participant will be ready to enroll in Advanced courses on Six Sigma that lead to a formal certification as a White Belt or Yellow Belt or Green Belt or Black Belt.

ALL of our courses in this series is developed based on decades of front-line industry experience of the instructor. 

WHO SHOULD TAKE THIS COURSE

Anyone who is involved with any process, be it manufacturing or transactional. It is uniformly applicable across any function. This course is equally important to any operator or management staff.

The series should form mandatory knowledge for any professional in manufacturing or Supply Chain or Project Management or HR or any function and especially a new employee.

This course is ALSO part of the is a Bundled Specialization course titled Six Sigma Specialization. You might also want to consider  to take the course on Lean Manufacturing Tools Specialization along with this course.
