Stock-taking is one way to maintain stock inventory by physically counting the stock of goods in the warehouse. However, it is not uncommon for companies to face data mismatches between existing records in the system and actual conditions in the warehouse on an ongoing basis. This problem can cause losses for the company in terms of quality, quantity, and storage costs. The DMAIC method (Define, Measure, Analyze, Improve, Control) is one method that can be used to overcome this problem. Based on data processing, it is obtained that the causes of stock-taking mismatches are outgoing goods that have not been inputted in the system, returns of goods that have not been inputted in the system, errors in inputting incoming goods into the system, different part numbers, incoming goods have not been inputted in the system with the largest percentage of causes being outgoing goods that have not been inputted at 49.60%. As for one of the efforts to control stock-taking discrepancies by making reports based on stock-taking deviation data within a certain period of time so that it can continue to reduce the occurrence of stock-taking discrepancies.

Furthermore, at the analysis stage Based on the identification of causal factors using FMEA analysis, it is known that the biggest contributing factor to failure is operator error in the operation of the milling machine. Then at the improve stage, make improvement proposals based on obtaining the highest RPN value from the factors causing disability using the TRIZ method. And the last stage, namely control, is the result of proposed improvements that can be made by the company to solve problems to reduce the number of product defects that occur during the production process.

Lean is a concept and technique for systems that optimizes patient benefit by decreasing waste and waiting time. The literature review approach is used in this study to acquire research data, with internet searches serving as a supplementary tool while looking for relevant papers. According to the study findings, mean hospital length of stay (LOS) fell by 24% throughout the intervention period in 259 patients with PMV (131 pre-intervention; 128 post-intervention) (29 vs. 22 days, p 0.001). This demonstrates that clinical redesign based on Lean Six Sigma decreases LOS in intensive care units. Other studies show that utilizing Lean Six Sigma has resulted in a 57% reduction in length of stay and an 88% reduction in the identification of non-value added tasks. Lean management in hospitals is a step toward greater service efficiency that has been shown to outperform Total Quality Management (TQM) and Plan, Do, Check, Action (PDCA) improvements. Customers and their families gain from shorter wait times, as do healthcare employees (medical, emergency, and non-medical) and hospital administration. The use of the lean six sigma approach in conjunction with the DMAIC cycle effects LOS reduction, indicating that lean six sigma can reduce LOS in hospitals.
