Inability to identify the issues in the bottleneck stations and production delays caused by process deviations not being addressed immediately.

Based on the data collected in their manufacturing execution system and from manual time studies, two stations were suspected to be the main bottlenecks. The bottleneck stations often have power chairs that are awaiting attention from management due to various issues. If the chairs are not addressed immediately or forgotten about, it can cause delays in the overall production timeline. The delay can impact ability to meet customer demand and thus negatively affect revenue. Furthermore, the productivity data collected prior to using i-5O was inaccurate, due to the fact that the methods relied on human inputs and data collection. It is also time consuming and impractical to continuously conduct manual time studies in which an industrial engineer would be required to monitor the station and record the productivity. This method can also produce inaccuracy in the data as the operators can perform differently when being actively monitored by an industrial engineer (i.e., lower performance due to anxiety from someone watching them).
