Overview

This course provides details of the main principles of failure analysis. System failures often occur during or shortly after the product development phase where new technologies are often brought to market under high time pressure and with limited resources. Under such conditions it is important that proven methodology and tools are available to quickly assess and understand such failures. Typically the root cause must be identified and solutions developed. A structured consideration of technical, organisational and economical aspects of the problem typically leads to effective recommendations. The topics covered in this seminar are illustrated using practical applications, with specific examples provided to clearly illustrate the concepts introduced.

Typical participants

Engineers with a background in development, validation, quality and production of technical products. Team leaders, product managers and technical management staff.

Main skills developed

Planning, management and execution of failure analysis activities Development of damage models for specific issues Effective application of specialised analysis methods Implementation of improvement measures
