The aim is to improve viewing quality of the product and to improve skills of developer.
During code inspection can be found and eliminated problems such as errors in format string, race condition, memory leaks and buffer overflows, which improves safety of a software product.
People may have a different approach to problem solving. Depending on their own experience, knowledge and skills to use different algorithms, data structures, approaches to lock patterns. If these approaches are not synchronized with each other, even in a small team, a complete solution will be a patchwork of approaches, patterns, structures. The review identifies a similar inconsistency and to open a dialogue on bringing code to a more homogeneous form.
