So, software bugs: what are they and why do they occur? Most likely, you know the reply to the first question. We all deal with software in everyday life, and it happens that sometimes, a program doesn’t work as expected. In most cases, it is connected with a coding error called a bug.
Why do the bugs appear though and why clients, even though they might hire an experienced team of developers, still have to pay for code with imperfections? Yep, it doesn’t always depend on a developer whether the product is going to function as expected. It depends on many factors, and you better learn more about them if you want to eliminate the possibility of bug occurrence.
Unclear software requirements
It happens sometimes that a client cannot specify what functionality the product shall have. It becomes especially problematic if the product is completely new and the developer cannot compare the requirements with those of similar products.
When the requirements are changing constantly, it also causes bugs. For example, when one feature shall be removed, and it is linked to other software components, its removal will cause a bug if the issue is overlooked. Sometimes, fixing a bug in one component might result in a new bug in a different component. If the developer cannot anticipate such issues, the number of bugs might be increasing instead of dropping.
