The goal of software bug prediction is to identify the software modules that will have the likelihood to get bugs by using some fundamental project resources before the real testing starts. Due to high cost in correcting the detected bugs, it is advisable to start predicting bugs at the early stage of development instead of at the testing phase. Th...

In recent years, the popularities of smartphones and its apps have been growing exponentially. This growth have made mobile applications more complex and require a large amount of energy to run in an efficient manner. It means mobile applications rely heavily on battery consumption. However, battery consumption is still a limiting factor in mobile...
Article
Full-text available
Studies related to resource consumption of mobile devices and mobile applications have been brought to the fore lately as mobile applications depend largely on their resource consumption. The study aims to identify the key factors and holistic understanding of how a factor influences Consumption Pattern (CP) effectiveness for an android platform mo...

Requirements volatility (RV) is one of the key risk sources in software development and maintenance projects because of the frequent changes made to the software. Human faults and errors are major factors contributing to requirement change in software development projects. As such, predicting requirements volatility is a challenge to risk managemen...
Conference Paper
The development of Web applications has a crucial role as most organizations have their own corporate Web applications to meet the needs of their respective businesses. Different needs create different complexities which represent a new challenge to Web application development. In order to ensure the timely delivery of a project, software providers...

Tourism in Malaysia has huge potential as the country is rich with different kinds of attractions such as historical places, different kinds of festival to enjoy and beautiful scenery to embrace. With the advances of the Internet, many investors have begun to produce different websites to promote their product; however, the quality is still valued...
Article
Software development effort estimation is vital to project success. Both underestimates and overestimates of software effort are universal phenomenon in the software industry, which is critical for resource allocation and bidding. The Class Point (CP) system level object-oriented size measure was proposed as an adaptation of Function Point (FP) ana...
Article
Full-text available
In this study, we present a window-based exponential effort estimation model to predict the effort required in terms of man days by using Unadjusted Function Point (UFP) size measure and eliminate the usage of General Systems Characteristics (GSCs). A very comprehensive statistical analysis and test was carried out on large amount of quality projec...
Article
Full-text available
It is widely accepted that sizing or predicting the volumes of various kinds of software deliverable items is one of the first and most dominant aspects of software cost estimating. Most of the cost estimation model or techniques usually assume that software size or structural complexity is the integral factor that influences software development e...

Software Cost Estimation (SCE) is a process of predicting the efforts and cost in terms of money, schedule and staff for any software system, Software cost estimation is an old arts come with the beginning of computer industry in 1940s and it has been developed many times until formulating function points by Albrecht in 1979. Nowadays software cost...
