the actions identified in a data collection plan, the team collected data on the cost categories associated with relocation costs. Using the File: , generate a Pareto diagram of cost, by category, to determine the categories of focus for your team. 23 Measure: Sample Answer 24 Measure: Cause and Effect Develop Cause and Effect diagrams for the top two Pareto categories of cost. For which causes would you develop additional data collection plans? Note: The cost “Transport of Belongings” will be the focused problem of this case study in the remaining slides. 25 Measure: Sample Answer H i g h T ra n s p o rt a t i o n C o s t sD i s t a n c eV o l u m e o f b e l o n g i n g sS t o r a g eS p e c i a l R e q u e s t sU n p a c k i n gP a c k i n g a n d m o v i n gT r u c k i n g C o m p a n yT r u c k U t i l i z a t i o nF u e l C o s tT ru c k i n gLaborM o v eM e t h o d sM e a s u re m e n t sEn v i ro n m e n tC a u s e a n d E f f e c t D i a g r a mD i v i s i o n a l Pro c e d u re sR e i m b u rs e m e n t L i m i tM o v i n g C o m p a n yW e i g h t A l l o w a n ceF l a t F e e26 Measure: Sample Answer H i g h T e m p o r a r y H o u s i n g C o s t sf u r n i s h i n g sd u r a t i o np o o l / s a u n a o f r o o m sA p t . v s . h o u s eC i t y v s . r u r a lN e i g h b o r h o o dLoc at ionF eat uresM at erialsM et hodsM eas urem ent sEnv ironm entC a u se a n d E f f e ct D i a g r a m27 Analyze: Benchmarking Exercise TRW‟s corporate Human Resources department, through their affiliation with the Society for Human Resource Management (SHRM), was able to acquire average relocation cost per employee from ten other panies. Using Minitab determine how TRW‟s expenditures pare to these other panies. Is the project goal of $15,000 per relocation reasonable? Be able to show why or why not. File: 28 Analyze: Benchmarking Answer TRW is „middle of the pack‟ when paring our costs to other panies. The project‟s goal of $15,000 seems reasonable because other panies are meeting it. TRW appears within reach of this goal. D . I.

Perform graphical analysis (dot plot amp。 box plot) of this data and be prepared to report your findings. File: Division Differences 30 Analyze: Hypothesis Testing Answers Plot the data, plot the data…. Something unusual (special cause) is occurring at Braking. They have decided to just give everyone $20xx0 for relocation expenses regardless of actual expenditures. 230001800013000T r a n s p o r t a t i o n C o s t s b y D i v i s i o nBC SEn g i n eO SSBra ki n gSt e e ri n g31 Analyze: Boxplot Answer Stack data in preparation for performing a Boxplot 32 Analyze: Boxplot Answer 33 Analyze: Hypothesis Testing Determine if statistical differences between divisions are present by performing a Test for Equal Variances and an ANOVA. Remember to meet all assumptions prior to performing these tests. Do not use the Braking division‟s data, as a special cause (providing the same amount for all relocations) was identified. Continue to use the file: File: Division Differences 34 Analyze: Answer Stack Data in Preparation to Perform Control Charting Data must be stacked without Braking Division „Individuals‟ chart will display if the process is stable over time 35 Analyze: Stable Process Assumption Answer In worksheet data Minitab has flagged some points. We reviewed the data for Steering division‟s flagged points and determined to use the data as it exists. 36 Analyze: Checking Data for Normality Data from the four divisions must be normally distributed to perform subsequent hypothesis testing. 37 Analyze: Normality Test Answers All are normal 38 Analyze: Test for Equal Variances Answer 14009004009 5 % C o n f i d e n ce I n t e rv a l s f o r Si g m a sP V a l u e : 0 . 4 1 8T e s t S t a t i s t i c : 0 . 9 5 4L e v e n e 39。 s T e s tP V a l u e : 0 . 3 0 2T e s t S t a t i s t i c : 3 . 6 5 2B a r t l e t t 39。 s T e s tF a ct o r L e v e l sSt e e ri n gO SSEn g i n eBC SV a r i a n c e Te s t b y D i v i s i o nNo significant difference in variance between divisions 39 Analyze: Hypothesis Testing Answers Statistically significant differences identified on average between divisions.
