THE EVALUATION OF WEBCOST USING SOFTWARE USABILITY MEASUREMENT INVENTORY (SUMI)

One of the crucial matters in software development is to what extent users can satisfy with the interfaces and functions provided. In order to measure whether the users are satisfied to use the software or tools, we need to evaluate the product before handover to the customer. However, the tools or instrument to be chosen to evaluate the product is still unresolved. In this paper, Software Usability Measurement Inventory (SUMI) is used to evaluate a tool for cost estimate called WebCost. WebCost is the stand alone application that developed by using Java programming language. A set of questions that adopted from SUMI instrument was used. The result shows WebCost provides easier interfaces and produces accurate cost estimation results.
