Can you please help me out regarding this. In TS16949 - there is a requirement of defining objetives for capability, reliability, maintainability. What is the difference between them and how can we put the target for these three? I am in the automotive industry

Definitions of terms could be as follows: Reliability, The probability of successfully performing an intended function under stated conditions without failure. In the automotive world, it could be a probability of success that the gas tank will not leak in 10 years. Maintainability, The relative ease and economy of time and resources with which an item can be retained or restored to a specified condition when maintenance is performed by personnel having specified skill levels using prescribed procedures and resources. In the automotive world, this would apply to the number of hours charged to the customer for repair functions. Capability, This is a performance metric such as number of miles per gallon, weight of the vehicle, horsepower of the engine. I would suggest that you review the MIL-HDBK-338B Electronic Reliability Design Handbook for terms and definitions, descriptions of tasks and testing methods.
