ABSTRACT This development presentation is of an information system for the network device monitoring system for Dandemutande. The easy to use system is named the Network Device Monitoring System (NDMS). The culmination of the system transition hinged on calming problems that stemmed from the old manual system. NDMS employs Graphical User Interface functionalities, an application server and a database server. The system has SQL Server as the back end. The Integrated Development Environment was PHP. Connectivity was offered through Microsoft windows 2010 with application server roles configured. The system can run on standalone Desktop Windows Operating Systems. In a bid to address the problems of the old system a sound alert notification service to the engineers is incorporated, outage records are automatically recorded and outages are quickly detected. The problem was defined in chapter one. The feasibility study justified why the system should be developed and is discussed in chapter two. System analysis was also considered to produce a useroriented system and user requirements in Chapter three. System design modelled the system and lastly system implementation and testing brought to life the conceptualized system. Lastly, experiences and observations for the future were also analysed and presented.

ACKNOWLEDGEMENT I owe the success of this project to a number of people. Without them the energy of doing this project would have vanished. Firstly, I wish to extend my profound gratitude to the Project Supervisor Miss Zinyengere A. for her insightful guidance. Truly, the path traversed was rough but you were there to even it. To Mr Muzadzi M. thank you very much for your amazing scholarly advice and support. That was awesome. Mr Chitongo D. I recognize you as a wonderful fellow. You stood tall in times of adversity. To my wife Dudzai, I stole most of your time doing this project but you tolerated me. You are a wonderful wife and mother, you even explained to our lovely son An ashe why I could not be there to cuddle them when they needed me most only to suffice during odd hours. Your tolerance is a bundle of joy. Lastly, I thank the Almighty God for giving me the strength when it seemed there was no way.
