The DMAIC process in Six Sigma improvement cycle is: Describe, mine (data), analyze, improve (process), constrain (costs) Define, minimize (costs), analyze, increase (profits), control (performance) Define, measure (process), analyze, improve (process), and control (performance) Describe, maximize (value), analyze, increase (profits), constrain (costs)The following acronyms are used in reliability formulas: mean time to failure (MTTF); mean time before failure (MTBF); and mean time to repair (MTTR). Using these acronyms, system availability is computed as: MTBF/(MTBF + MTTR) MTTR + MTBF/MTTF MTTF/MTBF 1 minus (MTBF + MTTR + MTTF)
