In the project-approval phase,due to constrained time for review,it needs quick and approximate estimate methods for obtaining software size to determine the budgets.This paper puts forward a quick estimation based on expert experience and random sampling,by which estimator first decomposes software into different software modules,the development organization pre-estimates size and cost of these different modules to declare funds,then estimator performs a detail measurement with expert experience and random sampling of software components,and estimates the total software project size by quick and approximates estimate method in order to get the total software cost.Application shows that this method is feasible.
