All changes to the Tektronix MRP system made 1981-1985 were zero defect Some were quite extensive.
The entire corporation's manufacturing system handling 1,000,000 parts was netted daily. Any defect would have caused the parts delivery/ordering system to crash on the IBM mainframe. Several thousand users.. Tek went bankrupt because the replacement MRP system and a major software offering were not zero defect.. Also look at the space shuttle manipulator code, written in Forth. tedc On Wed, Sep 10, 2014 at 6:51 AM, John Ralls <[email protected]> wrote: > > On Sep 10, 2014, at 5:05 AM, Ted Creedon <[email protected]> wrote: > > > mark up the screenshots with proposed changes > > > > then write the user's manual, systems administrator's manual & systems > > administrator's reference manual - submit for comments & approvals > > > > then write C++ header files that wrap your subroutines &compile & link > > > > only then can you begin code conversion > > > > writing code is the last step, not the first step - and its very boring- > > but you do get zero defect code > > I know of no project, waterfall or otherwise, that ever produced > zero-defect code. > > The changes we're discussing in this context are not reflected in the GUI > and so there would be no markup on screen shots and no changes to the > documentation. > > Regards, > John Ralls > > > > _______________________________________________ gnucash-devel mailing list [email protected] https://lists.gnucash.org/mailman/listinfo/gnucash-devel
