It has been claimed that dynamic prediction models can be used to help project managers make more accurate estimates than static prediction models. However, such a claim needs to be validated so that project managers can use dynamic models with confidence. In this paper, we discuss an experiment we conducted in an academic environment that compared a dynamic model using BBNs with a static model...

This paper describes enhancements being made to the University of Southern California’s COnstructive COTS (COCOTS) integration cost model to address security concerns. The paper starts by summarizing the actions we have taken to enhance COCOMO II to model the impact of security on development effort and duration. It then relates the COCOMO II approach to the COCOTS estimating framework so that ...

This paper presents a layered model which determines the software metrics in the lower layer it consists of three primitive primary software engineering metrics; they are person-months (PM), function-points (FP), and lines of code (LOC). The middle layer consists of the proposed function point which is obtained by grouping the adjustment factors. The proposed method uses fuzzy logic for quantif...

The COCOMO RAD MODEL (CORADMO) is currently implemented in two parts: a front end staged

Software Estimation has always been one of the prompting challenges for the software engineers. Software cost estimation techniques helps in forecasting the amount of effort required to develop software. Constructive Cost Model (COCOMO) is considered to be the most widely used model for effort estimation. Cost drivers have great influence on the COCOMO and this paper investigates the role of co...

S imple software cost-analysis methods are readily available, but they aren’t always safe. The simplest method is to base your cost estimate on the typical costs or productivity rates of your previous projects. That approach will work well if your new project doesn’t have any cost-critical differences from those previous projects. But it won’t be safe if some critical cost driver has degraded. ...

Software development effort estimation is among one of the most challenging jobs that software developers need to perform. Due to the lack of information during the early stages of software development, the developers often express their inability to estimate accurately the effort, cost and schedule of the software under consideration. This inaccuracy in estimation leads to monetary losses as w...

Software Effort Prediction is the process of estimating the effort required to develop software. Effectively controlling the expensive investment of software development is achieved by accurately estimating the effort. Effort estimation at the early stage of software development is very difficult because of lot of uncertainty in input parameters which decides the software effort. Adaptive Neuro...

The Authors have proposed a model that first captures the fundamentals of software metrics in the phase 1 consisting of three primitive primary software engineering metrics; they are personmonths (PM), function-points (FP), and lines of code (LOC). The phase 2 consists of the proposed function point which is obtained by grouping the adjustment factors to simplify the process of adjustment and t...

As the use of commercial-of-the-shelf (COTS) components becomes ever more prevalent in the creation of large software systems, the need for the ability to reasonably predict the true lifetime cost of using such software components grows accordingly. This paper presents empirically-based findings about the effort associated with activities found to be significant in the development of systems us...
