The correlation between software difficulty and care charges

Abstract EN

As software becomes more and more difficult due to increased number of module size, process size, and dividing difficulty, software care prices are often on the increase.

Consider a software such as Windows 8 operating systems with 80 million Source lines of code (SLOC) and with 3000 designers [1], there is no disbelief that such a large and complex software will require large amount of money, common and environmental factors to keep it.

It has been estimated that over 70% of the total costs of software development process is spent on maintenance after the software has been distributed.

This paper studies the relationship between software complexity and maintenance cost, the reasons responsible for software difficulty and why maintenance costs increase with software complexity.

The results show that there is a strong correlation between software complexity and maintenance costs.

That is, as lines of code increase, the software becomes more complex and more bugs may be presented, and therefore the cost of keeping software rises.
