This Book focuses examining some of the challenges faced by youth in applying modern technology in screening business ideas before implementation to enhance management of sustainable agri-based small and medium scale enterprises (SMEs) in a competitive economy particularly these hard times of unemployment and unpredictable social distress like Covid -19. This study explored the phenomenon of idea screening which expands current understanding of how youth perceive ideas for innovative agro-based projects in determining quality production and value addition. The study critically and contextually examined the best practice among youth in screening business ideas which will not only help Kenyan small and medium scale enterprises to survive and sustain the hard times but rather grow steadily and so become strong enough to contribute their quota to sustainable development in Kenya.
