Abstract
The authors compare alternative methods of cost estimation for a patient mu ltimedia education (PME) program, using a computerized weight-reduction PME project as an example. Data from the project planning and budgeting proces s 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 cos t of developing a graphical user interface provided a better estimate, as d id a tally reflecting the complexity and quality of media material in the p roject.
