Formal Technical Review The objectives of an FTR are: to uncover errors in function, logic, or implementation for any representation of the software to verify that the software under review meets its requirements Dr. Omar Hamdy Spring 2011 12 to ensure that the software has been represented according to predefined standards to achieve software that is developed in a uniform manner to make projects more manageable The FTR is actually a class of reviews that includes walkthroughs and inspections CS352 Software Engineering II

Review Meeting • Between three and five people (typically) should be involved in the review. • Advance preparation should occur but should require no more than two hours of work for each person. Dr. Omar Hamdy Spring 2011 13 • The duration of the review meeting should be less than two hours. Focus is on a work product (e.g., a portion of a requirements model, a detailed component design, source code for a component) CS352 Software Engineering II

Peer-Review A peer review is an assessment of a product conducted by a person or persons of similar expertise From a software development perspective: Dr. Omar Hamdy Spring 2011 14 – product is source code. – persons performing the review are programmers – used interchangeably with the term code walkthrough CS352 Software Engineering II

Peer Review Advantages A different perspective. “Another set of eyes” adds objectivity. Similar to the reason for separating your coding and testing teams. The ability to assess and accelerate progress. Is the team producing the needed output at the needed rate? Pride/reward. Recognition of coding skills is a significant reward for many programmers. Dr. Omar Hamdy Spring 2011 15 Project/module familiarity. Everyone involved in the review becomes more familiar with the project and the module. Less rework. Do it right the first time. Changes cost more later in the life cycle. Improved communication. More opportunities for interaction tend to lead the team toward improved communication. CS352 Software Engineering II

Challenges Time. Some peer reviews take a long time. Preparation. Reading unfamiliar code and correlating that code to unfamiliar documentation takes programmers away from coding. Dr. Omar Hamdy Spring 2011 16 Initial frustration. If team members are not familiar with peer reviews, the experience can be frustrating for all participants The need to show commitment. Although random peer reviews offer some benefit, that level of commitment is questionable.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
