>what is steps to design and implement high speed product ? Oy! This is a horribly big question, as a sketchy attempt at an answer, I offer: 0) good product concept (this is where virgin designs start) 1) market research 2) research existing similar or competing products and designs 3) IP search 4) preliminary product specs 5) preliminary design sketch 6) Go/No-Go (does the product make marketing, engineering and business sense?) 7) detailed product specs 8) prototype design 9) prototype evaluation (may include up through test marketing) 10) reworked product specs (this is often where continuing designs start a new cycle) 11) Nth revision design (N=1 for virgin designs) 12) build production prototypes (in-house? out-source? mixed?) 13) test (probably including some test marketing or sales to existing customers) 14) Tweaked Nth rev (N.xxx, xxx /= 000) 15) cycle 12, 13, 14 until one of several conditions (out of business, shot engineers, successful launch) 16) do not rest on laurels (prickly they are) go back to either 0) or 10) and do it again [Caffeine ergo sum.) ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
