Imagine we have 4 tasks that normally take 1 hour each. In the baseline, team A does all of the work, taking 4 hours. They have an occupancy of 80% meaning that translates to 5 hours of Team A’s scheduled time, costing £128. In the ideal scenario for moving the work, team B do it all with the same handling time and occupancy, but cost £72 leading to a £56 saving. However, what if team B can only complete two of the tasks but have to send the others back to team A (after spending half an hour identifying that they can’t finish them). In this case, if both teams have 80% occupancy, we need 3.75 team B hours but also 2 team A hours, leading to a total cost of £105 - still a saving of £23, but only 41% of the total opportunity. And that’s not the only thing that can affect cost. For example, if team B are twice as slow as team A at doing these tasks, then we will need 10 team B hours costing £144 - a £16 loss vs the baseline. Or if team B have much lower occupancy (e.g. if they are scheduled less efficiently) - if team B have an occupancy of 50% instead of 80%, we need 8 team B hours to do the 4 1-hour tasks, and this costs us £115. We only save £13 vs the baseline, 23% of the amount we save if team B have the same occupancy as team A.
