Efisiensi Proses Inspeksi Barang di Departemen Quality pada Perusahaan X menggunakan Pendekatan Business Process Improvement

Abstract

The inspection process plays an important role in ensuring the quality of oil and gas equipment manufacturing products. However, observations show that the inspection process is still carried out manually and has not been integrated. As a result, lead time often exceeds the standard time of two days. This study aims to analyze the causes of inspection delays and design process improvements using the Business Process Improvement (BPI) approach. The methods used include process mapping ( flowchart ), waste identification based on the 8Waste concept , and root cause analysis with RCA, 5- Why Analysis , and Fishbone Diagram . The results of the analysis indicate that waiting , motion , and extra processing activities are the main causes of delays. Process improvements are designed through inspection digitalization, a priority-based queuing system, recording results directly to the system, and an automated mechanism for re-inspection . Implementation of this design has the potential to reduce lead time to ≤ 2 days, reduce non-value added activities , and increase the efficiency and effectiveness of the QC team. The study recommends the implementation of an integrated digital system, improvement of the WIP layout, and the principle of continuous improvement on an ongoing basis.
