Manufacturing Black Belt On-Site Support – Inserter DOE Week 2

Event Consultant: Lynn Clark

Event Description: Inserter DOE Week 2

Event Location: Baldwinsville, NY

Preliminary Questions (from last report):

  • What is the relationship between the quality control measures Baldwinsville takes and the defects observed at another plant?
  • Is the sampling frequency appropriate to keep bad product out of customer’s process?
  • How well does BVL perform those measures?
  • How well do the quality control measures meet the customer specs (Capability)?

This Week’s Key Actions:

  • Conducted capability analysis of __________ hourly quality measurements.
  • Compared ___________ hourly quality measurements with customer defects.
  • Prepared samples for MSA evaluation.
  • Conducted operator measurements.
  • Performed MSAs.
  • Prepared conclusions and recommendations based upon MSA findings.
  • Reviewed and updated action registry.

Capability Analysis

  • Many parameters are measured hourly and entered into _________.
  • Data for Feb., March and April was evaluated.
  • Each parameter was checked for normality and stability before performing capability analysis.

MSA Sample Preparation:

  • Off spec item were used for this test so no additional scrap was generated.
  • The operator manipulated the _______ to induce variation consistent with that observed in the historical data.
  • Ten samples were pre-selected by CI team for each of the three parameters.
  • Four operators who routinely perform these test participated.
  • The samples were randomized before presentation to the operators.

MSA Analysis:

  • Each operator evaluated each sample twice
  • Two operators indicated they could not measure skew considering the way the samples were prepared,
  • Good measurement systems have <10% Tolerance and Process.
  • %Tol and % Process must be <30% for acceptance.

MSA Conclusions and Recommendations:

  • Current process measurements can’t tell good from bad, or if the process is getting better or worse.
  • No standard work for X exists.
  • Standard work for alignment and width were not present.

Use of black light at measurement station appears to aide in reduction of measurement error.            

 

 

 

 

 

 

Path Forward:

  • Develop/Revise standard work for all measurements
  • Trial use of black lights at measurement stations
  • Train all operators who perform the measurements
  • Re-run MSA to determine if %Tol is <30%.
  • Modify leader standard work to include spot checks of measurement system.

 

Define your Problem Statement.

The first step towards breaking your organizational log jams is identifying and verbalizing the challenge you're facing. What are you trying to solve? This simple Problem Statement exercise can have profound implications for your team. It helps you define the issue and gives TGG some sense of where the soft spots could be in your Order to Cash process. We invite you to take a few moments to fill out this form.
