Abstract
Quite a long time has passed since Function Point Method(FPM) first drew attention as a project estimation technique. And it has established its evaluation partly. However, it is yet far from being adopted commonly in the actual projects in Japan. What is preventing FPM from diffusing as a 'method'? How can we promote its wide use in the field? At first, I will show the advantages of FPM through comparison with the conventional estimation method based on program steps. Then, I will make its characteristics and current problems clear by practically counting Function Points. Lastly, I will consider what we should do for development and diffusion of estimation method.
