In sense of Relative and Absolute accuracy -both are askedIII- d) What is the actual production time (OT) taken per article (Attention:Be careful the observed time covers the service and machine time per article (OT) e) Calculate the observed manual labor time (means the service time) per article (Hint: Proportion of manual labour (servicing time) T 1/4) f) Calculate the normal labour time (service time) per unit you have calculated in c) Calculate the machine time per unit T.
