re level in c sy s x cs cmu edu tm msu edu tom writes nick haines sez given that i ve heard the shuttle software rated as level in maturity i strongly doubt that this having lots of bugs is the case level out of how many what are the different levels i ve never heard of this rating system anyone care to clue me in sei level the highest level the sei stands for software engineering institute i m not sure but i believe that this rating only applies to the flight software also keep in mind that it was not achieved through the use of sophisticated tools but rather through a brute force and ignorance attack on the problem during the challenger standdown they simply threw hundreds of people at it and did the whole process by hand i would not consider receiving a warning status on systems which are not yet in use would detract much if anything from such a rating i ll have to get the latest copy of the guidelines to make sure they just issued new ones i think also keep in mind that the sei levels are concerned primarily with control of the software process the assumption is that a well controlled process will produce good software also keep in mind that sei level is damned hard most software in this country is produced by engineering practicies that only rate an sei level if that insisting on perfect safety is for people who don t have the balls to live in the real world mary shafer nasa ames dryden fred mccall dseg ti com i don t speak for others and they don t speak for me
