Problem Statement:

Warranty returns are a major contributor to our Cost of Quality (COQ). It is one of the company’s strategic initiatives to reduce the COQ this year. Our highest sales volume motor is incurring $60,000 in annualized warranty costs out of $120,000 total in claims. This fix needs prompt attention to improve the customer experience and resolve complaints.

Major Project Activities and Challenges:

 DEFINE:

  • Defined the Project
  •  Created the Project Definition
  • Project Objective
  • Project Scope
  • Key Challenges and Goals
  • Identified Customers as External (Vendor) and Internal (Receiving, Customer Service, Production, and Accounts Receivable)
  • Completed the milestone chart showing milestones, responsible person and dates
  • Collected costs for the current process to be used for potential cost savings
  • Completed a flowchart of the process

MEASURE:

  • The team discussed the best measurements to use.
    • IT provided a data base of the required warranty data (see Warranty Trend chart)
    • Maxine H. gathered data for the Warranty Failure Modes (see Failure Mode chart)
  • Data was reviewed by team

ANALYZE: The team –

  • Brainstormed ideas by category (see Fishbone chart)
  • Identified root causes by asking 5 Whys (see 5 Why diagram)
  • Kirby documented results

IMPROVE:

  • Bill received approval from upper management for the redesign
  • Bill trained and communicated changes internally and externally

CONTROL:

  • Kirby wrote internal procedures for motor test sequence
  • Tony wrote new test frequency for heightened inspection for next 6 months
  • Bill wrote on-going audit process to maintain fix.

 Results & Final Conditions:

Goal Current After Results
Goal 1: Reduce warranty expense by 50% $60,000/yr. warranty expense Warranty expense reduced by $45,000.

New expense: $15,000

Reduced from $60,000 to $15,000.

Improved by 75%

Sustainment

I have added a daily audit of the process to my leader standard work.  This will scale back to weekly then monthly over time.  The team will be alerted should the internal team find an issue related to the improvements related to this motor.

 Conclusions/Lessons Learned

We saw great results with this project, and this is especially important because it was among the first Six Sigma projects for Minnesota Mfg.  The leadership team has a high interest in doing additional projects because there are a lot of other motors in the family to fix as well. The support of Minnesota Mfg. personnel for this project was very good since it had top management support. It took longer than the engineers were comfortable with, but everyone eventually bought into the changes.

 

One of the unintended benefits is that we have had a positive response from our customers.  Improving customer satisfaction has a strong link to supporting the strategic goals of the company.
