44% of the projects did not meet these three requirements, and 24% failed, i.e., they were cancelled prior to completion or were delivered and never used. That is, they were delivered on time, were within budget, and had the required features and functions. The 2009 Standish Group Chaos report (The Standish Group, 2009) indicated that only 32% of such projects had succeeded. Software development can be considered to be a most uncertain and complex project when compared to other types of projects, because it involves the creation of an intangible product, which is continually changing in response to customersвЂ™ requirements and the development of new technology. A validation of this model using the projectвЂ™s research data shows that this new approach is capable of improving the existing COCOMO estimation performance. It has the capability to not only integrate the effort estimation and risk assessment activities but also to provide information about the estimated effort, the project risks, and the effort contingency allowance necessary to accommodate the identified risk.

This chapter introduces the Fuzzy-ExCOM Model, which is used for software project planning and is based on fuzzy technique. However, as is common practice, these two activities are often disconnected from each other and project managers have come to consider such steps to be unreliable due to their lack of accuracy. In order to increase the chance of success in managing a software project, the project manager(s) must invest more time and effort in the project planning phase, which involves such primary and integrated activities as effort estimation and risk management, because the accuracy of the effort estimation is highly dependent on the size and number of project risks in a particular software project. AbstractSoftware development can be considered to be the most uncertain project when compared to other projects due to uncertainty in the customer requirements, the complexity of the process, and the intangible nature of the product.
