Kenya has emerged in recent times as one of the fastest growing telecom markets in the world. The Kenyan mobile industry's impact on economic growth is experiencing inconsistency, which requires an integrated model to study the various variables and factors causing this phenomenon. This thesis argues that the issue of mobile phone usage and economic growth is a complex technical and social phenomenon that needs to be understood from both [CT and social science perspectives.This research used the concept of governance-socio-techo-economic systems as the theoretical framework. We use system dynamics as both the methodology and tool to model the mobile industry. The outcomes are in the form of mobile user's projection, GDP growth, corruption indicators and policy projections. The tool produced is an intuitive one with the capability of replicating reality as evidenced from validation done. Sensitivity analysis of different policy levers (occupants' behaviour, insulation level, etc.) is carried out with the tool. We concluded that the outcome of this study provides a framework which if adopted across the region could guide regional plans, identify actors, as well as provide guidelines to implement strategic plans in developing economies by contributing to the various policy implementation scenarios in the ICT sector.
