    Application lifecycle management activities for quality assurance in software development
    (International Journal of Trend in Research and Development, 2017) Otibine, Tobias Okumu; Mbuguah, Samuel; Kilwake, Juma; Tsinale, Harriet Loice
    Lifecycle Management approaches promise more systematic and efficient ways to support the development and management of complex products. The concept of Application Lifecycle Management (ALM) indicates the coordination of activities and the management of artifacts during the software product‟s lifecycle. Most of the currently available unified ALM solutions are either based on basic version control and other 'low level' point-to-point integrations, or advocate the adoption of a new and expensive all-in-one solution from a single vendor. The problem with these current solutions is that the first does not go far enough to really provide the previously described benefits of applying an ALM solution, while the second one is often associated with high costs in tools, infrastructure and personnel which in turn affect the quality of software developed for SME‟s and middle level organizations. This paper discusses the effect of application lifecycle management activities on quality assurance in software development. The research employed multiple case study design. The data collection tools included Questionnaire, Observation and Interviews. ALM activities were found to be a direct predictor of Software quality assurance in software development. The research found out that ALM elements and their relations together with good documentation were very key in coming up with an efficient ALM solution and with improved process support and better knowledge and experience on ALM, application lifecycle management activities greatly affected the quality of software's developed thus improving on quality assurance in software development.

    Performance expectancy as a determinant for cloud computing acceptance in Kenyan Public Universities
    (International Journal of Applied Research, 2016) Tsinale, Harriet Loice; Wabwoba, Franklin; Ikoha, Anselemo P; Otibine, Tobias Okumu
    Cloud Computing is interrelated with a new perception for the provision of computing infrastructure and other services. It provides an infrastructure that is scalable, usable, virtually accessible and adjustable Information Technology resources that need not be owned by an individual but can be delivered as a service over the Internet. This paper discusses the effect of Performance Expectancy on the acceptance to use Cloud Computing within public universities in Kenya. Mixed method research was used with Purposive and Stratified sampling being used to select the sample population and the sample size was 181 respondents from four public universities which were arrived at by using proportional allocation method. Questionnaires and interviews were used to capture data. The study established factors such as Performance Expectance to be a direct predictor of acceptability of cloud computing, migration to the cloud computing should be structured and incremental and more people would use Cloud Computing if given access to reliable internet and computers.
