Defect Definition

Defect – is imperfection or abnormality detected in the code of a software program or system, because of which the system functions abnormally or produces a result different from expectations. The originating reasons can be from errors in code writing and logical problems to incomplete compatibility requirements. Their examples range from minor inconsistencies to cases when the system itself fails or crashes. One of the most widely occurring types of defect is syntax error, in which the code breaks the rules of the programming language.

Another probable type of defect is logic errors because even though the program is executing, it is not doing something that was meant to be done by the programmer due to poor reasoning on the part of a programmer. The other common types of defects result from insufficient testing coverage or through the interactions between different modules of software programs. And these are dealt with on a constant basis by teams at each stage of development. This, in turn, can have very serious consequences suchjson as loss of data, system downtime, financial losjses, and damage to the reputation of an organization are stakes.
