| Summary: | Goods Project is a company engaged in online-based convection in the city of Bandung, which was
founded on February 1, 2016. The services offered by the Goods Project are the manufacture of clothes
on a medium to large scale. In the last few years, the Goods Project has seen that the production process
is still not optimal because it always experiences from a predetermined schedule when producing large
quantities. This may occur because the production system is not optimal and there are small errors that
are not noticed by management, causing these errors to always occur.
Therefore, the author tries to do research related to the problems placed by the Goods Project using
the Lean Six Sigma concept with the DMAIC method (Define, Measure, Analyze, Improve, and
Control). Research begins by defining (Define) the production system and determining the scope of
the research. Then measure (Measure) the production system through data obtained from internal data
and presented in graphs and tables. Then analyze (Analyze) problems related to Root Cause Analysis
with the 6M Fishbone diagram concept (Man, Method, Material, Machine, Measurement, and Mother
Nature). And interviews with sources from the Goods Project, besides making observations to several
parts of the company.
From the results of the root cause analysis it was found that the problem was in the Human, Method,
Machine, and Measurement factors. In the method factor, it is found the order that the scheduling is
irregular and also the information on the remaining invoice payments which results in the expenditure
of raw materials. Factors It was found that employees do not have work contracts so that it causes no
commitment with the company and understanding of the established SOPs, and also no KPI in
employee performance appraisals. In the measurement factor, the company does not apply KPI to
production capacity and time, which results in an ineffective production process. Furthermore, on the
machine factor, the use of manual screen printing tools requires a longer time and also more labor,
besides that there are still some sewing machines that do not operate due to lack of labor.
Then the authors conducted a brainstorming related to the results of the analysis to optimize the
production system. The upgrade phase (Upgrade) results in that the Goods Project can solve the
problem by applying KPIs to several parts of the company especially on the administration, production
& human resources systems and also implementing a more effective scheduling system. Then carry
out control (Control) on the implementation of the strategy that has been done. |
