1.5. Loss in Productivity

Now, you have to account for the loss in productivity. So, the loss in productivity is also going to result in increase in the downtime cost of the machine.

This chunk explains the relationship between loss in productivity and increased downtime costs. Here, it is established that when a machine is not in operation and needs repair or maintenance, it results in a loss of productive output. This situation not only signifies downtime but also directly increases the costs associated with that downtime.

Imagine a bakery where the oven breaks down. While the oven is being repaired, no bread can be baked, leading to a loss of sales. The longer it takes to fix the oven, the more money the bakery loses. This downtime translates to increased operational costs.

So, after the service when it comes back to the project site we will be behind the project schedule. So, to bring the productivity back to the original production rate we need to engage the machine for more number of operating hours or we need to even increase the number of machines or we need to increase the number of workers.

This chunk highlights the steps necessary to recover from the loss of productivity caused by downtime. After a machine is repaired and back in operation, additional resources may be needed to restore the project timeline. This could mean increasing operating hours, adding more machines, or hiring extra workers, all of which come with additional costs.

Consider an assembly line in a factory where one of the machines breaks down. To catch up with production, the factory manager may decide to run the other machines for longer hours, add another machine, or hire temporary workers. Each of these actions incurs extra costs but is necessary to regain lost productivity.

So, that results in some increase in cost due to downtime. So, that is what is called as productivity adjusted cumulative downtime costs per hour that is what we are going to find here.

This portion introduces the concept of productivity adjusted cumulative downtime costs. When factoring in the need to restore productivity, the total cost associated with downtime increases. This adjusted cost gives a more realistic picture of the financial impact of downtime on productivity.

Using the earlier example of the bakery, if the bakery incurred additional costs for hiring a temporary worker to bake extra bread to meet the original demand after the oven was repaired, this added cost would be included in their adjusted operational costs. This helps the bakery better understand the true financial impact of the equipment failure.

So, you know that the productivity factor is given as the input data in this problem. So, for the first year there is no change at all, but for the second year there is loss in productivity, 0.98. So, I want to say 40.5 is my cost per hour, the productivity corresponding is 0.98, to bring back this productivity to 1, I need to spend some additional cost.

This section discusses how to calculate the productivity adjusted cumulative cost on a per-hour basis. The contribution of productivity factor (in this case reduced to 0.98) means more money needs to be spent to restore it to its original level of productivity (1). The costs incurred due to this need for additional expenditure increase the operational burden on the business.

Let's say a delivery company normally handles 100 deliveries per day, but due to new software that takes time to learn, they can only handle 98. If the cost to train employees on the new system results in additional costs, those costs need to be factored into the overall expenses, demonstrating how learning curves can affect productivity and financials.

So, this gives you productivity adjusted cumulative cost per hour. So, we have calculated it downtime cost. So, let us now move on to the next cost, which is nothing but your obsolescence cost.

The last chunk discusses the importance of calculating cumulative costs adjusted for productivity. It shows how previous calculations of downtime costs have led to understanding cumulative costs per hour and prepares the reader to move on to discussing obsolescence costs, which represent another layer of financial impact over time.

A car service center might calculate the total cost per hour of keeping a car in service, taking into account not just routine downtime from maintenance but also longer-term costs of keeping an older model car, which might be less efficient compared to newer models. Understanding these cumulative costs helps in financial planning for either retaining the vehicle or upgrading.
