Code inspection is a formalized and rather thorough approach to analyzing source code in order to identify problems and possible enhancements. This is a very important technique that the programming team must use to ensure that the software is correct of good quality, and easily maintainable.
Software inspection is an effective phase in developing software since it will lead to quality, reliable, and supportable systems hence, acts as a requirement of the existence of software. The code is reviewed for syntactical and logical errors and it also involves the check for the performance, readability, and maintainability of the code along with the design patterns and architectural standards.
Code inspection is a type of testing that is carried out on code prior to its inclusion into the main code base so that any faults can be corrected when they are easier and thus cheaper to do so. Nevertheless, it has to be taken into account that using code inspection can negatively influence the speed of development, because more time and effort are needed to review and analyze the code carefully.
