PopSolution Inc is a small IT Solution company based in Central Jakarta, Indonesia. They have just finished their sales pitch meeting with their latest potential client, an automobile sales company based in South Jakarta. The company was very satisfied with their portofolios, and asked them to provide a final quotation on the price that will be agreed upon. As for the project detail, the client asked for a simple web application with 3 main functions: (1) a homepage showing the companys credibility and location, (2) a page to list all cars the company is selling, and (3) a Contact Us page where future customers can fill their data to further be contacted by the companys representatives. Since the transaction is too substantial to be handled in the application, all purchase will be done outside of the web application. Every month, PopSolution spends 30.000.000 IDR for the overhead cost of all its employees. The organizational average productivity for the system of similar type is 25 FP/person-month. This means that with one person doing the job of 50 Function Point, it will take one month, with 2 persons doing the job, it will take half a month to finish. As the new member of the development team, you are asked to prove your expertise on software estimation by providing the team with Function Point Analysis (FPA) on your next internal meeting. Your tasks are:
