Definitions for Life, Shelf-life,life-cycle,...

We are currently working on a glossary for safety, quality, reliabilty and
maintainability for software for the intelligent transportation systems.

Please advise of definitions supported by the majority of your societal
disciplines in software, provide sources (e.g. IEEE, ISO, etc.) if
possible.

Life Cycle

Shelf Life

Transition

Retirement

Service LIfe

Life Span

I realize some of these are "stretching" the current hardware based
technical terms to fit (poorly) over software and software based systems,
but if they exist we are bound to consider honoring them.  Therefore if
you can provide a source then those terms will be better considered.

Thank you for your help...

Please allow me to stray from your topic.

Several years ago, I worked as a technician.  I worked in a development
laboratory and often found very hard and stiff o-rings in our parts bins.
Because I was just learning the different materials that o-rings were
made of, I was curious and asked what compound these o-rings were made of.

The senior technician replied, "Those o-rings are ten years old!"  It seems
after the shelf-life had expired and the parts could no longer be used to
build the customers' products, they became laboratory supplies from which
the savvy user must select parts adequate for the job at hand.
