This paper explains the use of kinesics and visual management to improve line productivity in engine assembly. We use principles of visual management and lean production together to reduce losses and reduce the time taken to produce one complete engine. Since the assembly is done by hand, humane factors such as vagueness, error, speed and many more affect the productivity. These can be reduced by using signs and symbols which help workers to make the right decision in the shortest time. we will explain in detail how this can be done, and how effective results can be, along with the better organization of the factory floor and better communication without any verbal intervention. This will help increase productivity and reduce losses hereby helping the line to maintain its lean standards.
