Offshore software development outsourcing (OSDO) is a well known business strategy adopted by many organizations in developed countries by outsourcing their software development work to low-wages countries. Developing software at offshore locations offers many benefits including access to skilled human resource and high quality software development at low cost. However outsourcing is not a risk free business for both vendor and client organizations. Vendor organizations need to address a number of factors for successful outcomes of the outsourcing relationships. Likewise knowledge sharing management (KSM) plays an important role in OSDO relationships. This research seeks to explore KSM in the context of OSDO relationships from vendors' perspective. The objective is to identify the factors that can play a positive or negative role in KSM by reviewing the literature in a systematic way. Systematic Literature Review (SLR) is based on a structured protocol, and is therefore, different from ordinary literature review. SLR provides in-depth, more thorough and comparatively unbiased results than ordinary literature review. We have developed a SLR protocol for the KSM, and are in the process of implementing the protocol. The expected outcomes of this review will be the identification of critical success factors and critical barriers to be addressed by vendor organizations for enhancing KSM in the context of OSDO relationships.

Spam detection is a significant problem which considered by many researchers by various developed strategies. Among many others, simple artificial immune system is one of those being proposed. There is a deficiency in number of optimization methods in simple artificial immune system (SAIS). This problem can be solved and eliminated using other optimization methods besides mutation. In this research, SAIS was hybridized by particle swarm optimization (PSO) for optimizing the performance of SAIS for spam filtering. PSO was used with mutation to reinforce the immune system's searches to find the best class in exemplar for classification. Achieved results represent the Hybrid SAIS and PSO is superior to that of a SAIS.

Component based software development system is composed of many components and it uses the reusable components as the building blocks for constructing the complex software system. The major challenges in CBS are testing component dependency that is; it is a tricky task to test each and every component for each possible input data which will lead to exhaustive testing. To reduce the cost, the industries are following some stopping criteria and release the product to the customer side. These stopping criteria will at times lead to skipping up of some of the components from rigorous testing. This will lead to hazardous side effects such as loss in terms of revenue, human life and resources. This insight leads to the need to identify critical components which have the higher dependability measure in terms of functionality and receives higher priority in testing with rigorous test procedures. Hence, this paper proposes a novel method for identifying the critical components from the Software under Test (SUT) and prioritizes them for testing with at most care based on various dependency metrics and measures among the components with the help of Component Execution Sequence Graph (CESG).

Currently, a number of specific international standards are made available within software engineering discipline to support Software Process Improvement (SPI) such as Capability Maturity Model Integration (CMMI), ISO/IEC 15504, ISO/IEC 90003 and ISO/IEC 12207. Some suggest on integrating and harmonizing these standards to reduce risks and enhance practicality, however there is no official initiative being made to date to implement this reality. Integrated Software Process Assessment (iSPA) is a proposed initiative being developed on the premise to harmonize and integrate a number of existing software process assessments and practices including improvement standards, models and benchmarks. A survey was conducted on thirty software practitioners to measure the strength and weaknesses of their organization's current software process. The survey also attempts to evaluate the acceptance and needs of implementation of a customized SPI model for Malaysia's SME.

The unpredictable fast growing dimension of the World Wide Web and its non-static nature causes considerable obstacles for Web crawlers including the presence of some incorrect and irrelevant answers among search results set and the scaling issues. Hence, solutions that are more promising are in demand to provide more accurate search outcomes. Because implementing existed Web page importance metrics either link based or context based within a parallel crawler can not be an absolute solution for the coverage of authorized fresh Web content and the accuracy concerns, so employing these metrics is not the final approach within search engines' architecture. This paper proposes an analysis on clickstream data in order to discover the popularity of Web pages in crawl frontier through proposing the metric itself and presenting the experimental results on ranking the UTM Web pages based on the proposed discussed metric.

In recent years, many new t-way interaction based strategies (where t indicates the interaction strength), particularly based on covering arrays, have been developed in the literature. In search of an optimal strategy that generates the most minimum number of tests, many of existing t-way strategies have not sufficiently dealt with test prioritization (i.e. in terms of maximizing new interaction coverage per test). Addressing this issue, this paper highlights a useful prioritization algorithm to reorganize the test cases in order to improve the rate of interaction coverage. This algorithm takes a pre-generated t-way test suite as input and automatically generates a priority ordered test suite as output. In order to demonstrate its applicability, this paper demonstrates the use of the algorithm to help prioritize the test suite generated by existing t-way strategy, MC-MIPOG.

Agile approach has become a popular process, in the software industry. Values such as quickness, flexibility and responsiveness are the main reason behind this fame. These values are fundamental as they define the culture of the software company where a set of practices can be followed based on them. According to Agile practitioners, knowing the most important values is the key to follow the best set of practices. Thus, the objective of this paper is to obtain a description of key agile values through the content analysis of the comments of agile manifesto signatories. The results have shown that the values associated with people are the most important, while the values associated with process come in the second level of importance.

One of the roles of e-government portals is to provide a one-stop service to users. In order to fulfill this role, it requires collaboration with other government agencies and businesses to provide an effective one-stop center for users to access and perform various services. Current e-government portals are mostly lack of interoperability whereby users still need to access government services from various portals or websites. Interoperability is a technical requirement to achieve government services collaboration and integration. There are many challenges and approaches to achieve better interoperability in e-government portals. Architecture-based and model-based approaches are essential research areas that can improve interoperability starting from the planning stages. Architecture provides overall overview of e-government components and relationship between components. This paper systematically reviews current architecture-based approaches to find a suitable approach and its requirements to produce a better architecture for e-government portal based on the lessons learned from the previous works.
