Measurement System Analysis

29

30

Elements of Variation

◆ Each operator measures the same part several times.◆ Data must be balanced; that is, operators must measure

each part the same number of times.◆ Units must represent the whole range of expected

variation. It is recommended to select parts within the specification range, that is, parts from the lower specification limit, parts from the upper specification limit, and parts within the specification limits.

◆ Operators must measure the parts randomly. They must not know which part number they are measuring at any given time.

31

Gage R&R Basics

32

Gage R&R Metrics

◆ Repeatability—The variation caused by the instrument. It is the variation observed when an operator measures the same part repeatedly using the same measurement instrument.

◆ Reproducibility—The variation caused by the measurement system. It is the variation observed when several operators measure the same part using the same instrument.

◆ Percent precision-to-tolerance (% P/T)—The percentage of the specification tolerance occupied by the measurement system variation.

◆ Percent gage R&R (% R&R)—The percentage of the total variation occupied by the measurement system.

Section VI: Application of Tools -Analyze Phase

Hypothesis Tests:

- 1 sample t, 2 sample t, ANOVA

- 1 sample sign, Krustal-Wallis

- F test, Levene

◆ A hypothesis test is a method of making decisions using data from our processes.

◆ In statistics, a result is called statistically significant if it is unlikely to have occurred by common causes of variation alone, according to a predetermined threshold probability called the significance level.

51

Overview

◆ If the p-value is less than the required significance level, then we say the null hypothesis is rejected at the given level of significance. – Under this scenario, we might accept the alternate

hypothesis. ◆ If the p-value is not less than the required significance

level, then the test has no result. – The evidence is insufficient to support a conclusion.

52

Overview

◆ To summarize, here is a slogan you can use to remember when to reject or fail to reject the null hypothesis (H0):

“If p-value is low, the null hypothesis must go.”

◆ In other words, when the p-value for the null hypothesis is lower than a predetermined value, then the null hypothesis must be rejected.

53

Overview

◆ When dealing with hypothesis testing, there are four decisions that can be made.

◆ Two of those decisions are correct decisions, while two of them are wrong decisions.

◆ In statistics, those wrong decisions are called type I error and type II error.

54

Overview

55

Overview

◆ One-Sample t-Test– Comparing one average to a target value

◆ Two-Sample t-Test– Comparing the averages of two populations

◆ One-Way ANOVA Test– Comparing the averages of two or more populations, using

just one factor

56

Comparing Means

Three months ago, a company implemented a new CAPA investigation process after a massive training. The company wants to know if the training is paying off, that is, if the average closure time for the investigations has decreased significantly. Before training, average closure time was 20 days.

57

One-Sample t-Test Example

58

One-Sample t-Test Example

A company wants to compare how long it takes (in hours) for each shift in the quality control laboratory to perform an analytical test on a specific product. There are two shifts: shift 1 and shift 2. A given test is selected, and the times to complete that test are collected and analyzed with statistical software.

59

Two-Sample t-Test Example


NOTE: A test for variances must be performed prior to the two-sample t-test

61


A company wants to compare the performance of three shifts in terms of the manufacturing cycle time to determine if there are significant differences in their averages. After verifying the assumptions related to normality of the data and equal variances, the box plots shown in the next page were developed and a One-Way ANOVA performed.

62

One-Way ANOVA Example

63


64


Although it was proven that the average manufacturing cycle time for each shift was not statistically different, the performance among the shifts does not appear to be the same. For that reason, the company developed a quality index to measure their performance. The index is based on a scale of 1 to 5, where 1 means poor performance and 5 means excellent performance.

65


66


67


◆ One-Sample Sign Test– Comparing one median to a target value– Non-parametric equivalent to the one-sample t-test

◆ Two-Sample Mann-Whitney Test– Comparing the medians of two populations– Non-parametric equivalent to the two-sample t-test

◆ Krustal-Wallis Test– Comparing the medians of two or more populations, using

just one factor– Non-parametric equivalent to the ANOVA test

68

Comparing Medians

The median cycle time for investigation has been 25 days (50% of investigations needed more than 25 days to be completed). After new root cause analysis training, three months of data were used to evaluate the improvement (if any).

69

One-Sample Sign Test Example

70

One-Sample Sign Test Example

A pharmaceutical company wanted to determine if there are significant differences in the hardness of the tablet they manufacture using two different pieces of equipment. In order to analyze this, a period of one year of production was collected from each machine. After performing a normality test, it was noticed that data do not follow the normal distribution. The histograms in the next page show a p-value for the Anderson-Darling normality test of 0.0000 for each machine, indicating that the data do not follow the normal distribution.

71

Two-Sample Mann-Whitney Test Example

72


73


A pharmaceutical company wanted to analyze three different suppliers of a fluid used in their manufacturing process in order to select one of them. A critical characteristic of the fluid is viscosity, measured in centipoise (cP). The specifications for the viscosity of the fluid range from 2.4 to 3.6 cP. Data from the three suppliers were analyzed and a histogram and descriptive statistics of them generated.

74

Krustal-Wallis Test Example

75


76


◆ F-test– Comparing variances of two populations

◆ Bartlett Test– Comparing variances of two or more populations

◆ Levene Test– Comparing variances of two or more populations when

they do not fit a Normal distribution

77

Comparing Variances

A company wants to analyze two different adhesives for the transdermal patches they manufacture. Adhesives on a patch generally help maintain contact between the transdermal system and skin surface. The adhesiveness of the patches is critical in the drug delivery mechanism, its safety, product quality, and efficacy. As such, a good adhesive should easily adhere to the skin with an applied finger pressure and be tacky enough to maintain a strong holding force. The adhesive should also be easily removed from the skin without leaving a residue. The specification for the adhesiveness of the transdermal patch ranges from 300 to 3500 g/system.

78

F-test

79

F-test

80

F-test

Let us suppose that in the previous example the manufacturer would like to test a third adhesive. Since the F-test can only compare two variances at a time, we need to perform a Bartlett test.

81

Bartlett Test Example

82


83


84


A pharmaceutical company wants to evaluate the time it takes their analysts to perform a certain laboratory test. They have noticed too much variation in the time it takes the various shifts to complete the test and would like to investigate the reason for the variation. In order to start the analysis, the time it took each analyst to perform the laboratory test (in hours) is collected. Then, the data are segregated by shift.

Rational Subgroups

Nonrandom Patterns

Variables Control Charts:

- IMR, Xbar & R, Xbar & s

Attributes Control Charts:- p, np, c, u

◆ One of the most important concepts in control charting is the rational subgroup.

◆ A rational subgroup is just a subset of a group intended to be as homogeneous as possible. In that way, we will be able to compare the variation within each subgroup and compare the variation between subgroups over an extended period.

◆ But how do we determine the appropriate subgroup size? That will depend on the process being studied. 93

The Rational Subgroup

94

Nonrandom Patterns

◆ Test 1—One point more than 3 sigma from centerline◆ Test 2—Nine points in a row on same side of centerline◆ Test 3—Six points in a row, all increasing or all decreasing◆ Test 4—Fourteen points in a row, alternating up and down◆ Test 5—Two out of three points in a row more than 2 sigma from

the centerline (same side)◆ Test 6—Four out of five points in a row more than 1 sigma from the

centerline (same side)◆ Test 7—Fifteen points in a row within 1 sigma from the centerline

(either side)◆ Test 8—Eight points in a row more than 1 sigma from the centerline

(either side)95
