Abstract

<p>It is necessary to have an agreement between the customer and the IT vendor which they understand the result and process of project delivery estimation. However the IT vendors have difficulty to explain complexity and dynamic difficulty of the project specification for the customers who do not have the IT expertise. On the other hand the customers feel unsatisfied about the present situation because they often receive unexpected project estimation from the IT vendors without clarifying the way of the estimation. It said that only 14% of customers were satisfied with the estimation and the pricing in JUAS IT trend survey, 2011. From that survey shows that there is huge gap between the customers and IT vendors about the feeling convinced and satisfied with the estimation. Therefore this study clarifies the estimation process and variation factors, and makes it visible.</p>
