DESIGN FOR QUALITY AND RELIABILITY

INTRODUCTION FOR DESIGN FOR QUALITY AND RELIABILITY

Design for quality (DFQ) & Design for Reliability (DFR) not only ensures that the product will work after assembly but how long an item will perform its intended function for a designated period of time without failure under specified conditions.

Design for reliability (DFR) is to avoid issues such as Takata airbag and Microsoft Xbox issues to avoid warranty costs and provide customer satisfaction. Field failures are very costly and can cost billions of dollars in warranties (aside from loss of business and market share). Clearly, in order to be profitable, an organization’s products must be reliable, and reliable products require a formal reliability design process and also designed for quality.

COURSE OBJECTIVES

1. Reduces time-to-market
2. Gain an understanding of the methods, terms and metrics used in reliability, when to apply particular tools during the product development life cycle and the associated benefits and drawbacks of each.
3. Implement a holistic DFR process in product/system design environments and leverage the benefits of this process, namely the Faster, Better, Cheaper values that drive the Reliability 3.0 process.
4. Build an effective reliability culture within the organization and help to determine what needs to be added or improved in your DFR initiatives.
5. Evaluate your strengths in each methodology, which will serve as a guide for any additional skills you may need to acquire or augment.
6. Designing for mistake proofing (poka yoke)
7. The proper techniques to achieving Design for Reliability (DfR).
8. Gain detailed knowledge of designing reliability
9. Understand the concepts of reliability
10. Apply the right tools where is needed
11. Ensure all the requirements are met
12. Understand mathematics of reliability
