Abstract:
AMD’s Fab 25 has a high rate of
technological change that sometimes requires
“super-expediting” of extremely high
priority lots. AMD developed a seven-step
procedure for managing such lots: 1) ensure
production management buy-in for lot
priorities; 2) identify a “key
expediter” responsible for getting the
lot out quickly; 3) clearly state expectations
for all involved in processing the lots; 4)
define tactical communication methods; 5)
establish a system for tracking and
forecasting lot performance; 6) execute the
tracking and forecasting system; and 7) report
progress and get assistance from management as
needed. AMD applied this procedure to the
first lot of a critical new product. This lot
went from being 14 days behind schedule to
shipping early.
