Evaluating instructional formats and performance metrics in manual assembly task

BackgroundAssembly is crucial in manufacturing processes, particularly with the increasing trend of customer assembly enabled by e-commerce platforms. Comprehending the importance of explicit assembly instructions is essential for improving efficiency in manual assembly activities.ObjectiveThis study aims to assess the effect of various assembly instruction formats, particularly evaluating the role of color and text, on established performance metrics in manual assembly activities.MethodsMultiple assembly instruction formats, encompassing both colorful and non-colored images with and without textual guidance, were created and utilized in manual assembly activities. A rigorous experimental strategy was implemented, including 40 participants to evaluate assembly performance measures.ResultsThe study results revealed that the addition of color and text instruction has a slight effect on the performance of the assembly, but this effect isn't significant at this level of assembly complexity.ConclusionImplementing specific assembly instruction formats can enhance performance and reduce costs, highlighting the significance of customized, explicit instructions for improved work efficiency.
