One of important aspects of software projects is to estimate the cost and time required to develop projects. Now-a-days, this has become one of the key concerns of project managers. Accurate estimation of essential effort to produce and develop software is heavily effective on success or failure of software projects and it is highly regarded as a vital factor. Failure to achieve convincing accuracy and little flexibility of current models has attracted the attention of researchers in the past few years. Despite advances to estimate effort, no agreement was obtained to select an estimation model as the best one. One of the effort estimation methods which are highly regarded is COCOMO.
