Market Feedback mapped to

Stress Categories

Morten Løgstrup ChristensenAugust 2013

The purpose of mapping market feedback to stress categories is to find the dominating scenarios leading to negative market feedback. This information is important when:

• Assessing the level of robustness towards the end-user

• Assessing risks

• Designing new effective tests with focus on achieving a high level of robustness towards the end-user and avoid negative market feedback

• Prioritizing test activities during product development

Codes

When products are returned from the market with a reported fault they are often investigated or repaired.During repair or investigation a code is typically assigned stating the technical finding.

In Novo Nordisk they are called Result Codes.
