Abstract

The most difficult task in software development planning is to estimate the size of the end product, the resources that will be required, and the time required to complete the project. Function Point Analysis (FPA) is a method of projecting size, while the Constructive Cost Model (COCOMO) is a method of estimating resources and schedules.Both tools were developed primarily from experience with third generation language (3GL) development environments. Provisions for interchanging the tools to estimate fourth generation language (4GL) environments are not always straight-forward -- particularly when estimating a form-based environment such as Oracle SQL*Forms.Both FPA and COCOMO models can be adapted to estimate the costs of developing projects using non-procedural fourth generation languages like SQL*Forms. These tools can be used together to estimate size and project costs, and to assist in assessing the sensitivity of various project costs to development parameters such as programmer skill level and the user's concern for reliability.
