Warranty Management

“A customer is never out of warranty, even if his product is”: Seth Godin

Rejection is part and parcel of our life. It may be in a relationship, business or sports. The important point is what we do with rejection. Do we succumb under it or we raise ourselves and find possible solutions?

Something similar is with Warranty Management in Industry. Although the intention is not to produce and despatch any rejection sometimes it does happen which translates into customer end rejection, zero Kilometer rejection (dealer end), Warranty/Field failure or recall.

A warranty is a contractual obligation incurred by the manufacturer in connection with the sale of the product. The purpose of the warranty is to establish liability in the event of the premature failure of a product or the inability of the product to perform its intended purpose.

OEMs (Original Equipment Manufacturer) extend warranties to emphasize product quality and combat competitors. Warranty management has a direct impact on the profitability of an OEM, its dealer network and other supply chain partners.

In IATF 16949 Standard, the following is the definition related to Warranty.

No trouble found (NTF) - Designation applied to a part replaced during a service event that, when analyzed by the vehicle or parts manufacturer, meets all the requirements of a “good part” (also referred to as “No Fault Found" or “Trouble Not Found")

Following are the clauses of IATF 16949 where the reference of Warranty / Filed Failure / Recall is specified

IATF subscribing OEM’s have specified some requirements related to Warranty.

Warranties reflect far more than an OEM’s or supplier’s confidence in its product. They are also

• a selling strategy
• a tool for customer retention

There are many reasons for high Warranty.

OEMs’ top issues are

• Resource shortages
• Lack of product design involvement

 Suppliers’ top issues are

• Lack of collaboration with the OEM/supplier
• Lack of diagnostic data
• Lack of product design involvement.

 Some of the key action points to control warranty is by asking the following question (5W, 1H):

• Whose involvement (employee, Suppliers, Dealers, Consumer) and leadership is needed to increase collaboration (to understand facts and take a decision)?
• What more should companies be doing to improve warranty cost-effectiveness?
• Where do collaboration breakdowns occur most frequently (working in silos, no teamwork)?
• Why do they happen?
• When should an organization analyze the data to take desired actions?
• How can we use warranty management to improve the overall quality and reliability of parts, systems and vehicles?

As per clause 10.2.5 of IATF 16949, when specified by the customer, the organization shall implement the required warranty management process.

As per Clause 8.5.5.1 (Feedback of information from Service), the organization has to establish a process of communicating any service concern (Warranty) to related process owners in the organization so that suitable action can be taken and its implementation can be shared.  

Key steps for Warranty Management:

1. Sources of information related to warranty (service) parts

2. Methods of collecting warranty parts

3. Methods of investigation of returned warranty parts

4. No trouble found case management

5. Reporting findings and implementing corrective actions

6. Sharing lessons learned / preventive actions

Possible KPI by an organization:

PPM - (warranty) parts per million (of parts delivered to the customer)

Cost ratio - Cost of warranty compensations against sales value

Cost per unit (CPU) or Cost per Vehicle (CPV): The calculated cost of warranty-related repairs by totaling the sum of the repair costs divided by the number of vehicles produced to determine a per-vehicle cost.

Global KPI:

Warranty Claims Totals: Total amount of warranty cost paid by OEM’s and their suppliers in a year.

Average Claims Rates: Average of last 5 years

Warranty accrual Total: Tentative cost of warranty cost set aside for a year (assuming that warranty will come after some time).

Average Accrual Rates: Average of last 5 years

Accruals per Unit Sold: Tentative cost of warranty per vehicle sold

Warranty Reserve Totals: Amount kept aside every year for warranty failure cost 

Benefits to Top Management:

• Cost of rejections will be low
• Sustainability of the organization will increase
• Quality consciousness will improve
• Delivery performance will improve
• Possibility of getting new business improves

Some question to ponder:

• Do organizations have an agreement with their suppliers related to warranty failure?
• Does the organization have a systematic analysis of the warranty rejection?
• Does the organization communicate the importance of warranty in the organization?
