Reviewing is a key activity that can find defects at an early stage of system and software development. Since it is often cheaper to fix defects at an early stage, reviewing is a good technique for improving both product quality and project cost effectiveness. Currently, there are many review techniques proposed and many experiments have been performed to compare the review techniques. However, to data there have been no review techniques or experiments that have focused explicitly on the relative business value or mission value of the artifacts being reviewed.

520 $a Reviewing is a key activity that can find defects at an early stage of system and software development. Since it is often cheaper to fix defects at an early stage, reviewing is a good technique for improving both product quality and project cost effectiveness. Currently, there are many review techniques proposed and many experiments have been performed to compare the review techniques. However, to data there have been no review techniques or experiments that have focused explicitly on the relative business value or mission value of the artifacts being reviewed.
520 $a In this dissertation, I provide Value-based review techniques adding cost effectiveness and value of each issue into review processes, and report on an experiment on Value-based review. I developed a set of VBR checklists with issues ranked by success-criticality, and a set of VBR processes prioritized by issue criticality and stakeholder-negotiated product capability priorities. The experiment involved 28 independent verification and validation (IV&V) subjects (full-time working professionals taking a distance learning course) reviewing specifications produced by 18 real-client, full-time student e-services projects. The IV&V subjects were randomly assigned to use either the VBR approach or the previous value-neutral checklist-based reading (CBR) approach that had been used in the course. The difference between groups was not statistically significant for number of issues reported, but was statistically significant for number of issues per review hour, total issue impact in terms of criticality and priority, and cost effectiveness in terms of total issue impact per review hour. For the latter, the VBRs were roughly twice as cost-effective as the CBRs.
520 $a The dissertation also covers threats to validity and limitations of the experiment. Threats to validity were present but appear to have been adequately addresses. The main limitation of the experiment was its coverage of reviews by individuals as compared to groups. For reviewers by groups, it is likely that combinations of VBR and risk-driven forms of perspective-based review (PBR) approaches would be most cost-effective. This and other topics are attractive candidates for further research.
