Consider a sequential process where customers need to be served by steps $1,2,3,$ and $4($the sequence needs to be followed$).$ Assume employee A is responsible for steps $1$ and $3,$ employee B is taking care of step $2,$ and employee C is doing step $4.$ Which of the following is most effective to decide the true process capacity in this case? Developing SPC to compute the process vield rate then capacity$$ Using VSM to decide the process capacity$$ The process bottleneck is employee A since she$/$he needs todo two tasks$$ The true process capacity depends on whoever has the smallest employee capacity $($among A$.$ B and C$)$
