As developers put in a great deal of effort writing a code. But, they invest much more time maintaining and understanding that code. How frequently do we go back and find out that code has become this tangled mess that we nearly can’t even understand? It’s presumably more frequent than we acknowledge. We wonder, “How did this occur? How did this code get so messy?” Well, the most probable factor is software complexity.
What’s Software Complexity?
In the last couple of decades, software complexity has created another era in computer science. Software complexity could be characterized as the standard driver of cost, reliability, and performance of the software. Regardless, there is no common agreement on the definition of software complexity yet to lay it out simply we can say, “Software complexity is the level of challenge in analyzing, maintaining, testing, planning and modifying software.” In other words, software complexity is an issue that is in the entire software development process and each period of the software development life cycle (SDLC).
In general, software Complexity impacts the required effort to analyze and depict the requirements, design, code, test, and debug the system during the development stages of software. In maintenance stages, complexity shows the difficulty in error correction and the required effort to modify distinctive software modules.
How Can We Categorize Software Complexity?
Software Complexity is hard to evaluate without using complexity measures and there are many of them. But in this section, we’ll explore one of the widely used measures to categorize software complexity; Function Point.
FP: It is broadly used to measure the size of the software. Function Point focuses on functionality given by the system. Features and functionality of the system are used to categorize the software complexity.
Function point relies on five parameters, named External Input, External Output, Logical Internal Files, External Interface Files, and External Inquiry. To consider the complexity of software every parameter is further categorized as simple, average, or complex.
Complexity is a subject that can be very intimidating to developers. In any case, that is a result of the theory and the language surrounding the idea. They cause it to appear to be more complex than it is actually. All you need to do is to keep your functions and methods smaller. If you observe that they’re getting large, figure out how to break them into smaller ones. That is all that there is to it.
