The Cost Of Bugs

Cost of Bugs



In any software development project, bugs are a part of life. However, the sooner they are discovered and fixed, the less impact they have on your project’s success and, most importantly, the budget.

Software development in years past was primarily “waterfall”, in which all of the details of the complete system were analyzed and collected ahead of time. Development would then proceed, and during various stages of testing, bugs would be located and fixed. The primary drawback to this approach was that because all development happened in one single, mammoth process, finding a bug late in the process was very costly, as it may have affected other parts of the system, technical documentation, or any number of pieces that make up the system.

The advent of agile development(specifically Scrum, a version of which Spud employs) means that a large system is broken up into iterations called sprints that are continually developed and tested. Finding and fixing bugs right away reduces the overall cost and also has the benefit of producing defect-free, usable software more quickly.

For example, let’s say you are in the middle of working on a sprint. While working on this sprint, you find something isn’t working the way the client would want it to. Through agile development, the bug is detected while working on this particular sprint and is fixed right away instead of finding the bug outside of the sprint, which could cause chaos within other sections of the software. Also fixing bugs right away tends to be easier for the programmers, as the code is still fresh in the minds of the development team.

By breaking a large system down into sprints, our developers are able to locate bugs right away and fix them quickly. This eliminates time and headaches for developers down the road and allows us to meet the client’s budget and time line.
