Analysis of Employee Work Quality Using Statistical Process Control and Compliance with Standard Operating Procedures (Study in the Merchandise Inspection Department of the Foodhall Senayan City)

Abstract

The objective of this research is to evaluate the effectiveness of employee performance in implementing Standard Operating Procedures (SOP) within the Merchandise Inspection/Receiving Department at The Foodhall Senayan City. This research is of a qualitative descriptive nature, with a focus on Statistical Process Control (SPC) as a measurement instrument. It employs the Implementation of Seven Key Elements in SOP, covering efficiency, consistency, error minimization, problem-solving, and defensive limitations. Five individuals participated in this research: Branch Manager, Receiving Supervisor, and three Receiving Staff members. Data collection techniques were based on direct observation, interviews, and documents used as references for the receiving staff's work procedures. In this study, the author used Statistical Process Control (SPC) on Attribute Control Charts, specifically using P-charts as a measurement tool for Quality Control checks on goods. The Implementation of Seven Key Elements in SOP was used to deepen the investigation into problem-solving that could not be explained using numerical data. Based on the analysis results using Statistical Process Control (SPC) for the current period, the average reversal rate is 0.02, indicating proximity to the Lower Control Limit (LCL) of 0 or zero defects. Meanwhile, regarding the usage of the Implementation of Seven Key Elements in SOP in the Merchandise Inspection/Receiving Department at The Foodhall Senayan City, it is evident that in the implementation of these seven key elements, there are still some shortcomings. These deficiencies include error minimization, process mapping, employee protection, and defensive limitations.
