ABSTRACT 

The aim of this paper was to present factors which influence work-related adoption of social media among government employees. The study adapted the Unified Theory of Acceptance and Use of Technology (UTAUT) and integrated it with three constructs namely Hedonic Motivation (HM), Perceived Personal Image (PI) and Attitude (AT). The sample of study consisted of 600 usable responses collected using survey questionnaire from employees based in Tanzania Ministries, Departments and Agencies (MDAs) employing convenience sampling technique. The data was analyzed using Structural Equation Modelling. The results showed that, PI and HM influence attitude (AT), while PI, Social Influence (SI) and AT influence Behavior Intention (BI). Moreover, SI, PI, AT and BI showed significant effect on actual Use Behavior. Furthermore, the results showed that PI is affected positively by HM and SI. The added constructs proved to be important modifications to the UTAUT model as suggested by the increase in explained variance by UTAUT from 70% to 73% on BI and from 53% to 73% on actual use behavior.

A few studies have devoted efforts towards establishing the impact of in-house software development on software. Therefore, this paper is an effort towards establishing the impact of in-house software development practices on system usability. In pursuit of this paper, a sample of a sample size of 169, at 95% confidence level, with margin error of 5% was drawn from bold software users, i.e. 300 employees who used the all software including those ...
