Effort Estimation of Web Applications through Web CMF Objects

Several Content Management Frameworks (CMF), either open source or with a commercial license, are available to help the publication of huge amounts of information and to develop Web applications. Unfortunately, developing Web applications through a CMF is not exempt from cost and time overruns, as in traditional software projects, and currently there is no estimation model able to adequately measure the effort of Web application development. This work presents a new methodology for estimat­ing the effort of Web applications developed with a Content Management Framework (CMF). We present the new key elements for analysis and planning, needed to define every important step in developing a Web application through a CMF. Using those elements, it is possible to estimate the effort needed to build such an ap­plication in man-days. We also present the experimental validation of the proposed methodology per­formed on a 9-project dataset, provided by three different Italian software companies.
