Therefore, increased software complexity means that maintenance and enhancement projects will take longer time to completion, will costs more, and will result in more errors. As noted in [23], since the 1990s, many of the ailments plaguing software could be traced to one principal cause-complexity engendered by software's abstract nature.
Software complexity is a branch of software metrics that focused on direct measurement of software attributes. Software complexity is widely regarded as an important factor in software maintenance costs.

Software is an intangible product, which is notoriously difficult to measure (see our in-depth article on software metrics). However, one aspect of software which can be easily quantified is its complexity. Complexity reflects the number of entities that comprise the software, and the number of interactions between them.
May 7, 2014 this is inherent complexity: the difficulty of the actual problem that the software in question is trying to make simpler and better.
The complexity of even little, contemporary software applications is merely massive, and complexity grows non-linearly as the size of a software system boosts. Complexity grows, at least as quickly as the square of the size of the program. It is called this the size/complexity dynamic of software development.
Jul 29, 2015 what is the real cost of software complexity? recently, i had an interest about the runtime cost of complexity.
Software development is fundamentally based on cognitive processes. Our motivating hypothesis is that amounts of various kinds of information in software artifacts may have useful statistical relationships with software-engineering attributes. This paper proposes measures of size, complexity and coupling in terms of the amount of information, building on formal definitions of these software.

Software complexity refers to the extent to which a system is difficult to comprehend, modify and test, not to the complexity of the task which the system is meant to perform since two systems equivalent in functionality can differ greatly in their software complexity due to the design of the software.
The results of our findings 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 introduced, and hence the cost of maintaining software increases.
1 toward a definition of software complexity when applied to a system, the term complexity has different dimensions and associated under-standings. One definition of complexity is based on the “ease of understanding” a software model representing a software system design specified by an engineer.
In software development, ‘complexity’ refers to the nature and number of interactions between entities within a system, rather than to the complexity of the task that the system performs. As a system is developed, it is likely that the number of entities will grow, and with this the number of interactions between those entities.
