A reliability engineer has her most important role in the specification, design, and development phases of a new item. In these phases, the reliability engineer helps the development team to

1 Identify potential failures of suggested component and module concepts such that failures may be designed out.

2 Quantify the reliability of suggested system concepts.

3 Provide input to decisions about modularization, stacking, and system layout.

4 Make tradeoffs between factors such as cost, functions, performance, reliability, time to market, safety, and security.

5 Identify weaknesses of the system design such that they can be corrected before the system goes to manufacturing or to the customers.

6 Clarify benefits and drawbacks related to redundancy of components and modules.

7 Identify causes and effects of possible failure modes.

8 Compare the LCC of design alternatives.

9 Evaluate the cost of suggested warranty policies.

10 Calculate the reliability of system options as input to choice between these.

11 Plan and perform reliability acceptance or qualification testing (e.g. in a TQP framework).
