When the Problem Isn’t the Software, but Everyone Thinks It’s a Bug

For a programmer, hearing a client say, “Your software has a bug” can be one of the most unpleasant calls. Many times, a client or one of the software users has contacted me and confidently, sometimes in a frustrated tone, said: “Your software has a bug.” Sometimes, users do not even distinguish between an error, an issue, and a bug, and any problem they encounter while using the software is considered a bug.

In such situations, I would first ask questions about how the problem occurred and what steps the user had taken.

After investigating, it would become clear that the software was working correctly and that the problem had been caused by incorrect use of the system or failure to follow the defined process. I would then provide additional guidance and ask them to pay closer attention when entering information into the system.

One of my experiences in this area involved a project where the client reported a problem with the system’s financial calculations. The claim was that a customer had paid their debt and settled their account, but the software was still showing the customer as owing money.

At first glance, this could have appeared to be a software error. However, after further investigation, it became clear that the software’s calculations were correct and that the problem originated elsewhere.

The client initially recorded customer invoices in a notebook and then entered the same information into the software. All additions and subtractions were calculated manually, and this process resulted in discrepancies in the financial records.

What was interesting was that the client said many similar financial discrepancies had occurred throughout the year and that the software had identified them. These were discrepancies that had previously been difficult to detect through the manual process.

This experience taught me an important lesson:

Sometimes the software did not create the problem; the software is actually the tool that reveals an existing problem in the business process.
