Automatic Cost Estimation Analysis on Datawarehouse Project with Modified Analogy Based Method

The approximate cost of software is the success of the project determinant. Before determining the estimated cost of the software, it must first estimate the effort, because the business effort is a component that affects almost all cost objects. In this study we used Analogy Modification method that will be implemented in a system to estimate the cost of building data warehouse automatically. The data used is Data warehouse UNSRI of development project. From the value of automated estimation result by MRE system equal to 1.735888282 with effort value equal to 20.97, it can be concluded that the error value generated is big enough (above zero). This measurement suggests that price estimated by software engineering techniques, especially software cost estimates using analogy modification methods, are significantly different from the actual field price or pricing. After the observation between the approximate price and the actual price offered in the field, it can be stated that the price of data warehouse in the field is highly valued at low. It does not even reach 50% of the estimated price.
