N2 - The authors compare alternative methods of cost estimation for a patient multimedia education (PME) program, using a computerized weight-reduction PME project as an example. Data from the project planning and budgeting process and actual costs of the completed project are analyzed retrospectively to calculate three different estimates - pre-work, post-work, and actual work. Three traditional methods of estimating the cost of computer programs (the lines-of-code, function point, and task ratio analyses) underestimate costs in this example. A commercial program (Cost Xpert) that calculates the cost of developing a graphical user interface provided a better estimate, as did a tally reflecting the complexity and quality of media material in the project.
