1 2 During regression testing, a modified system is often retested using an existing test suite. Since the size of the test suite 3 may be very large, testers are interested in detecting faults in the modified system as early as possible during this retesting 4 process. Test prioritization attempts to order tests for execution so that the chances of early detection of faults during retest5 ing ...

Organizations generally have a variety of IT projects to implement, but only limited resources to develop them. As information technology and systems pervade organizations, the pool of potential IT projects is continually increasing. In this paper, we explore IT project prioritization practices in a real life context and contrast them with the rational approaches which dominate the IS literatur...

Abstract— The most appropriate prioritization method is still one of the unsettled issues of the Analytic Hierarchy Process, although many studies have been made and applied. Interestingly, many transportation evaluation and selection models using AHP apply only Saaty’s Eigenvector method. Many theoretical studies have found that this method may produce rank reversals and have proposed various ...

The expenditures for hospital drugs are continuously increasing, and grow much faster than the global hospital budgets do. This explosive growth is caused mainly by a few so-called 'expensive drugs' of which the oncolytics form the main part. The global budgets should stimulate more effective provision of care ('technical efficiency'), however the room for technical efficiency is decreasing. Ho...

Summary Message framing contributes to an increase in public support for invasive species management. However, little is known about people’s preferences the multiple objectives of management within different contexts relating challenges and benefits We examine Japanese citizens’ goals free-roaming unowned cat ( Felis catus ) three contextual frames by applying experimentally controlled informa...

This chapter provides an overview of techniques for prioritization of requirements for software products. Prioritization is a crucial step towards making good decisions regarding product planning for single and multiple releases. Various aspects of functionality are considered, such as importance, risk, cost, etc. Prioritization decisions are made by stakeholders, including users, managers, dev...

Regression testing is a time consuming, costly process of re-running existing test cases. As software evolves, the regression test suite grows in size. Test case prioritization techniques help by ordering test cases such that at least the test cases which cover the changes made in the software are executed amidst resource and time constraints. Genetic Algorithm (GA) has been widely used for tes...

A requirement may be defined as a demand or need. In software engineering, a requirement is a description of what a system should do. Requirements prioritization plays an important role in the requirement engineering process, particularly, with respect to critical tasks like requirements negotiation and software release planning. Selecting the right set of requirements for a product release lar...

This Software testing is “Performing Verification and Validation of the Software Product” for its correctness and accuracy of working. Every time it is not possible to perform each and every test case. Hence it is important to decide test cases prioritization. The aim of Test case prioritization is to prioritize the test case sequences and finding the faults as early as possible to improve prof...

Regression test case prioritization optimizes the ordering of test cases to be executed to meet some criteria like maximum code coverage or high rate of fault detection. In prior work we prioritized test cases according to a hybrid technique using variable based method that combined both selection and prioritization. We inferred in our approach that variables are vital source of changes in the ...
