Analyzing Relationship between the Amount of Effort in Review Processes and the Total Amount of Effort for Embedded Software Development Projects

In this study, we examined the relationships between the amount of effort identified in review processes and the total amount of effort in end of projects by using data accumulated by a company. We grouped the data by the amount of effort in a review process, and a volume of target projects to find out the relationships. We analyzed the relationship using the Shapiro-Wilk test and Spearman´s rank correlation coefficient. The results mean that a volume of the target project can create groups more efficiently to find out a relationship between the amount of effort in review processes and the total amount of effort. They indicate that the total amount of effort can probably be estimated by using the amount of effort in review processes which is grouped by a volume of target projects.
