Software reviews are one of the most efficient quality assurance techniques
in software engineering. They are used to find defects in early stages of a
projects progress and help team members to get a better understanding of
the code. Undetected defects during the software development process can
have significant consequences, such as reduced customer satisfaction,
increased safety risk and decreased productivity of the users. In order to avoid
them, development teams use software reviews to improve the quality of the
product by reviewing interim deliverables during the development. In the last
thirty years several formal and less formal approaches for the application of
reviews were developed. Despite their advantages, they are not universally
used because in many cases a review tool that assists a companys review
process does not exist. This is presented in a case study with the company
Frequentis, whose task-based development process is not sufficiently
supported by an existing review tool. The internationally acting company
develops software in the field of civil air traffic management (ATM), and
therefore has to fulfill the DO-278/ED-109 software standard. A significant
part of the standard is devoted to the application of code reviews. This work
describes a lightweight task-based review process which was developed
based on theoretical analyses and company specific requirements. It is related
to a peer deskcheck or passaround method and consists of four phases. A
case study shows how the process can be used by Frequentis for the
assurance of software quality. Based on this, a custom review plug-in for the
popular Eclipse development environment was designed and implemented.
This plug-in is used to apply the task-based review process. Furthermore, it
supports the planning of reviews by suggesting qualified reviewers for parts
of the source code. For the verification of the review results and the review
coverage, it also allows the generation of reports.
