I want to know the answer to the following question:
What is the most common reason for software failure?
All the background I'm provided with is that "A common cause of software failure (real or perceived) is a lack of its compatibility with other application software, operating systems (or operating system versions, old or new), or target environments that differ greatly from the original (such as a terminal or GUI application intended to be run on the desktop now being required to become a web application, which must render in a web browser).". Is that enough to answer the question?
Answer: yes
