Software Engineering Costs

                               Distribution of costs across the different activities in the software process depends on the process used and the type of software that is being developed.Software Engineering Costs Eg: Real-time software usually requires more extensive validation and testing than web-based systems.In the waterfall approach, the cost of specification, design, implementation and integration are measured separately. System integration and testing is the most expensive development activity.Normally this is about 40% of the total development costs.
