The Cost-Benefit Analysis of Process Automation: How Long Does It Take to Save Time?

In today's fast-paced business world, many companies are considering automation as a way to improve efficiency, reduce costs, and save valuable labor time. However, before jumping into an automation project, it's essential to conduct a cost-benefit analysis to determine whether the investment is worthwhile. One of the most straightforward ways to assess the potential savings is by using a simple formula that compares the time it takes to automate a process with the time spent performing the task manually.

The Formula for Time Savings

To determine if automating a process will save labor time, we can use the following formula:

Time_to_automate < (time_to_perform * amount_of_times_done)

Where:

• Time_to_automate is the total time required to automate the process.
• Time_to_perform is the amount of time spent on the task each time it's done.
• Amount_of_times_done is how often the task is performed.

Let's break down this formula and look at a real-world example to understand how it works.

Example: A Banking Company's Decision to Automate

Imagine a banking company that is considering automating one of its internal processes. This process currently takes 40 minutes each week to complete. The automation process is estimated to take a total of 10 hours. The company wants to know how many weeks it will take before automation becomes worthwhile, i.e., when the time saved by automating the process will outweigh the time spent setting it up.

Step-by-Step Breakdown

Convert Time to Consistent Units

First, we need to ensure that we are using the same units of time for both sides of the equation. The automation process will take 10 hours, but the time spent manually performing the task is measured in minutes. To make the comparison easier, we'll convert the 10 hours into minutes.

10?hours×60=600?minutes

Substitute the Values into the Formula

Now that we have the time to automate in minutes (600 minutes), we can plug the values into the formula.

600<40x

Here, 40 represents the number of minutes it takes to complete the task manually each week, and x is the number of weeks it takes before automation begins saving time.

Solve for x (Weeks)

To determine the number of weeks it will take for automation to pay off, we need to solve for x (the number of weeks):

(600/40)<x

15<x

This means that it will take more than 15 weeks for the company to start saving time on the process.

A Real-Life Story: The Tale of Sarah’s Spreadsheet Nightmare

Let's take a step back and add a little story here. Imagine Sarah, a project manager at a mid-sized company, who's been spending hours every week tracking and updating reports on a spreadsheet. It wasn’t her favorite task, but it was necessary. Each week, she’d spend 40 minutes painstakingly entering data and double-checking for errors. The task was repetitive and time-consuming, but at least it was predictable.

One day, Sarah’s company decided to explore automation for repetitive tasks like hers. The automation tool they chose was capable of handling the entire process in a fraction of the time—10 hours of setup, to be exact.

At first, Sarah was skeptical. After all, 10 hours of setup? That sounded like a lot of time to her. But when she sat down to do the math, she realized something: in just 15 weeks, the company would start saving her time. After that, every minute spent automating would be one less minute she’d have to work on those dreaded spreadsheets.

Sarah took the plunge with automation, and within months, she was able to shift her focus from managing data to tackling more strategic projects that actually required her expertise. The initial 10-hour investment in setting up the automation process had more than paid off.

Conclusion: The Payoff Period

In this case, it will take 15 weeks before the banking company starts to see a return on its investment in automation. After 15 weeks, the time saved each week by automating the process will exceed the initial time spent on setting up the automation. Beyond this point, the company will continue to save valuable labor time, which can then be reallocated to more productive tasks.

Why Automation Matters

While the initial setup of automation can require significant time and resources, its long-term benefits are clear. In addition to saving time, automation can reduce human error, improve consistency, and free up employees to focus on higher-value tasks. In industries like banking, where efficiency and accuracy are critical, automating repetitive processes can have a profound impact on productivity and overall business performance.

Final Thoughts

Before implementing any automation project, it's important to understand the financial and time implications. Using a simple cost-benefit formula like the one above can help businesses determine how long it will take for automation to become worthwhile. In the case of the banking company, after 15 weeks, automation would start to save them time, and the investment would prove to be worthwhile in the long run.

Ultimately, while automation may require an upfront investment of time and resources, the benefits of reduced labor costs, increased productivity, and enhanced accuracy often outweigh the initial effort.
