Software bugs can lead not only to material losses, but also can damage human's health. For example, actors on the stage of a theatre can get injured if suddenly one of the scenery begins to go down on the stage at the wrong time. However, the connection between the errors in code and the health damage of medical software is more obvious. Let's talk about this topic.

This article focuses on the teams of developers who create the programs for a medical equipment. I hope they will not stay indifferent and will check their code. Let's recall two famous cases where errors in programs, related to medicine, became the reason for bad news.


Firstly, it is a series of tragic events caused by the errors in the Therac-25 device of radiation therapy. This device has caused at least six overdoses of radiation within the period from June 1985 to January 1987, some patients received doses of tens of thousands of rad. At least two people died directly from the radiation overdoses. Software bugs of the device were the reason of the tragedies and the main problem was the incorrect security strategy.

Many people believe that software testing is the search for the bugs. Sometimes, I say to testers, "Do not try to find as many errors as possible, try to miss as less as possible!” and they do not understand me. What's the difference?

There is a huge difference! In this article I want to tell you about that difference, and what tools you need to use for a useful troubleshooting.

What is troubleshooting?
