For five elements (K, L M, N and J) continuous timing method is applied for a manual task. Four parts are produced each cycle. J is an irregular element performed once every four cycles. Elements K, L, M, N were rated at 90% and element J was performance rated 100%. The PFD allowance is 16%. a. What is the normal time for the cycle? b. What is the standard time for the cycle? c. If the operator completes 900 parts in a shift which works 450 min., what is the operators efficiency. Element K L M N J Observed time (min) 0.35 0.60 0.86 1.46 2.00
