Although it is essential that quality and efficiency of reviews has been improved in each stage of software design and development processes, in many cases, quality of the review is inclined to be decreased, because of difficulties of focusing on the review points due to the unclearness of the review theme about which the review participants are going to discuss. On the other hand, efficiency of the review is also inclined to be decreased, mainly because of spending some extra time to prepare review materials before the review starts and difficulties of referring materials that review participants want to refer on demand. This paper reports about an activity we are conducting, whose puropose is improving quality and efficiency of reviews. In this activity, we provided a couple of review rooms where we can conduct reviews in accordance with our own review theme, and we can refer review materials electronically with projectors and screens on demand while the review is under way.
