Siderscan is especially effective on projects that are large, long-term, and/or involve engineers of varying skill levels.
When you modify duplicate code, not only the target code but also other duplicate code blocks
must be searched without omission, and determine if the same modification must be applied or not.
In projects with many developers, the person who created duplicate code is often different from the person who modifies it, which increases the risk of correction errors.
1+ year development period
The DRY (Don't repeat yourself) principle is an important principle for maintaining software
quality, which states that "duplicate information with the same meaning or function in multiple places
should be avoided as much as possible. In practice, however, there are situations in which the DRY principle
is not followed during the development process, and duplicate code tends to increase gradually.
After a certain number of years of development, managing duplicate code becomes beyond human control.
Skill gaps among members
Differences in member skills also have a significant impact on software quality. Large-scale
projects involve a variety of developers with different backgrounds, including juniors, outsourcing
engineers, and offshore engineers, resulting in differences in skill levels.
In such projects, code duplication tends to occur frequently. Debugging problems caused by duplication are very difficult to fix and can be a potential risk to the project.
