estimation  Estimation Inside-out Software size estimation is one of the most critical and difficult activities in the software planning process. Measuring software size goes a long way toward determining the effort, schedule, and budget required for a project. Learn how misjudging or misunderstanding the scope and size of a project can result in budget and schedule overruns, and failed deliveries that can cause total project failure. Read More

estimation  of Software Estimation Introduction Software development has spawned an independent industry, with organizations offering software development services exclusively. As it is perhaps in the nascent stages, the processes of asking for service, offering a service, and pricing are all somewhat haphazard. Software development falls into the category of the services industry as opposed to the product industry—that is, a service is offered, and not a product. Many parallels can be drawn with similar Read More

Productivity for Software Estimators
Presently, software estimation is considered to be an art rather than a science. At the heart of this perception is the lack of understanding of the concept of

estimation  Concerns with Software Size Estimation The present scenario in the software industry is that there are multiple units of software size measures. These units of measure include function points, use case points (UCP), object points, feature points, Internet points, test points, mark II function point analysis (FPA), lines of code (LOC), etc. There is no accepted way of converting software size from one unit of measure into another. One odd aspect of these measures is that the size of the software is Read More

So, it has become necessary for the outsourcer and the provider to reach an agreement about the size, development effort, cost, and development schedule of the software product being outsourced. This has caused software estimation to move from hunch-based estimation to the use of mature, research-backed estimation techniques. The process of estimation has also moved from manual estimation using Read More
