| Summary: | The accuracy and efficiency of cost estimation methodology for web-based application is very important for software development as it would be able to assist the management team to estimate the cost. Furthermore, it will ensure that the development of cost is within the planned budget and provides a fundamental motivation towards the development of web-based application proíéct. The literature review reveals that COCOMO II provides accurate result because more variables are considered including reuse parameter. The parameter is one of the essential variables in estimating the cost in web-based application development. This research investigates the feasibility to combine and implement COCOMO II and el pert I Udgment technil be in a tool called WebCost. In estimating a cost, the tool considers all variables in COCOMO II and rei bires el pert l udgment to key-in the input of the variables such as pro I éct size, pro I éct type, cost ad i Ustment factor and cost driven factor. I leveloped in JA I A, WebCost is proven able to estimate cost and generate its estimation result. The usability evaluation conducted had shown that WebCost is usable when compared with other tools I lit has its own advantages. WebCost is evidence suitable for everyone especially the prolect managers, software practitioners or software engineering student in handling the cost estimation tasks. © 2010 IEEE.
