Consider the following four step process:The following data are available for the four steps:A B C DActivity time per unit (min) 0.25 0.33 0.2 0.5Capacity per worker (units/min) 4 3 5 2Number of workers 2 3 2 4Suppose the steps in activity D are made easier, so the activity time per unit in step D is reduced by 50% (to 0.25 minutes per unit). If the assignment of workers to steps remains the same, by how much does the capacity of the entire process increase in units per minute
