What qual­ity and re­li­a­bil­ity mean to the con­sumer

Electronics For You - - Manufacture -

For the user of a prod­uct, the prod­uct should per­form its in­tended/de­signed func­tion when used as per the pre­scribed method and in pre­scribed op­er­at­ing en­vi­ron­ment. If it fails to per­form a re­quired func­tion or de­vi­ates from the re­quired per­for­mance, it is de­clared as a bad-qual­ity prod­uct.

Not only should the prod­uct per­form its func­tion im­me­di­ately af­ter in­stal­la­tion but it should per­form with­out fail­ure over its re­quired op­er­a­tional life time. If it fails very fre­quently dur­ing its op­er­a­tional life-time (for ex­am­ple, a tele­vi­sion fail­ing twice or thrice ev­ery year), then also it is de­clared as a bad-qual­ity prod­uct.

Qual­ity and re­li­a­bil­ity engineers re­late qual­ity to gen­eral per­for­mance of a sys­tem when it’s op­er­ated un­der al­lowed stresses, and re­li­a­bil­ity to time-ori­ented per­for­mance with­out fail­ures.
