Development of a mobile application system for raha beverages company limited management communication at different levels
(NM-AIST, 2021-08) Daudi, Ngollo
The existing forms of communication at Raha Beverages Company Ltd are not effective enough hence bringing about the demand for an effective communication system in the company. The Raha Application is a system that supports internal communication across all levels of the company. As the company expands through the means of strategic planning in a certain time frame, these transitions bring about change in the company structure as well as processes ranging from production, transportation, the workforce to communication which runs in parallel. Forms and methods of data collection described involved were interviews, observations, document analysis, joint application design, brainstorming and prototyping. Interview and observation were the main used forms. This system was implemented using agile software development, which defines software development from program specification, design, implementation, and testing which are interleaved that support frequent delivery of new versions for evaluation. The mobile application is designed for internal communications at different levels among employees. Each employee will have to be given initial login credentials to enable first-time login but will be recommended to change the credentials once logged in according to their preferences. The mobile application system developed was tested and evaluated to assess its usability for effective communication. The system provided benefits like better management control, better decision making, improved efficiency in communication, a faster way of reporting, easy access and availability of information. Therefore, this study presents a mobile application system solution that will support sustainability in communication throughout the entire company for effective company communication

Ugali is a thick porridge that is one of the popular staple foods in East Africa. Traditional methods of ugali preparation, cooking, and consumption are described. Firewood has been used as the primary energy source followed by charcoal. In East Africa, electricity grids have expanded and reached a wider network, which has opened opportunities for electric cooking to domestic consumers, especially in urban that was previously dominated by charcoal, which is in scarce supply due to government regulations on environmental conservation. In this project, the smart ugali cooker was designed and developed to automate the process of cooking ugali in households which is faster, safer, and healthier. The smart Ugali cooker is an automated kitchen appliance designed to boil the mixture of water and maize flour into a dough mixture referred to as ugali. It consists of a driving motor, stirrer, flour dispenser, heat source, a cooking pan, a temperature sensor that measures the temperature of the boiling water in the pan, and the control system (Arduino board). The device has basic units that are a dispenser, stirring unit, electronic control unit, pan, and electric heater. These units were fabricated and integrated to form the complete cooking device. Thereafter, the Arduino board was programmed to control the cooking process. Cooking experiments were conducted, on the cooking duration and the texture of ugali based on water to flour ratio. The results showed that ugali was cooked after ten minutes and the quality was good for consumption. In recommendation, the rightful flour to water ratio must be applied to obtain the desired texture of ugali
