—Traditional cost estimation models in software engineering are based on the concept of productivity defined as the ratio of output to input; for instance, detailed software estimation models, such as COCOMO, can take multiple factors into account, but their multipliers lead to a single perspective based on the productivity concept. A less explored relationship in software engineering is the on...

Project planning is one of the most important activities in software projects. Poor planning often leads to project faults and dramatic outcomes for the project team. If cost and effort are determined pessimistic in software projects, suitable occasions can be missed; whereas optimistic predictions can be caused to some resource losing. Nowadays software project managers should be aware of the ...

The process of resolving conflicts among software quality requirements is complex and dificult because of incompatibilities among stakeholders' interests and priorities, complex cost-quality requirements dependencies, and an exponentially increasing resolution option space for larger systems. This paper describes an exploratory knowledge-based tool, the Software Cost Option Strategy Tool (S-COS...

Cost estimation is an important aspect for making high-quality management decisions in the software industry. It is also related to determining how much effort and schedule are needed to complete the task on time. The challenge is to predict the accuracy of software development effort and schedule. Several models and approaches are available in the literature for such problems. This paper provi...

The prediction of software development effort has been focused mostly on the accuracy comparison of algorithmic models rather than on the suitability of the approach for building software effort prediction systems. Several estimation techniques have been developed to predict the Effort estimation. In this paper the main focus is on investigating the accuracy of the prediction of effort using RB...

Cost, schedule and quality are highly correlated factors in software development. They basically form three sides of the same triangle. Beyond a certain point (the “Quality is Free” point), it is difficult to increase the quality without increasing either the cost or schedule or both for the software under development. Similarly, development schedule cannot be drastically compressed without ham...

Software engineering cost models and estimation techniques are used for number of purposes. These include budgeting, tradeoff and risk analysis, project planning and control, software improvement and investment analysis. The proposed work uses neural network based estimation, which is essentially a machine learning approach, is one of the most popular techniques. In this paper the author has pr...

Large amounts of software are running on what is considered to be legacy platforms. These systems are often business critical and cannot be phased out without a proper replacement. Migration of these legacy applications can be troublesome due to poor documentation and a changing workforce. Estimating the cost of such projects is nontrivial. Expert estimation is the most common method, but the m...

CASE (Computer Aided Software Engineering) tools are believed to have played a critical role in improving software productivity and quality by assisting tasks in software development processes since 1970s. Several parametric software cost models adopt “use of software tools” as one of the environmental factors that affects software development productivity. Several software cost models assess t...
