System study involves documenting an organization's existing systems and identifying
current deficiencies to design systems and procedures that will help them accomplish their
objectives and become more effective and efficient. The study was conducted to improve the
current system at PV Tech Corporation in Rosario, Cavite, using different industrial engineering
tools and techniques. PV Tech Corporation is a company that supplies and produces solar panel
modules. It caters specifically to the needs of its users, providing clients with a reduced
environmental impact on their property and lower operational costs. The module inspection
section is a support section of PV Tech Corporation that engages in inspecting incoming
modules from the supplier. Various problems in the operations of the current system of the
section were analyzed using different industrial engineering tools as well as a process audit
checklist.
To address the problem in the module inspection section, researchers used a process
audit checklist as the research instrument for the study, and the respondents were those who
had direct experience in the module inspection section of PV Tech Corporation. The DMAIC
methodology was used for the improvement of a current system. For the define phase,
problems were identified through a process audit checklist and using different industrial
engineering tools. The measure phase includes creating and executing data through a process
audit checklist. In analyze phase, an interrelationship diagram was formulated to further analyze
and to recognize the processes in the module inspection section that were used to determine
root causes of problems and opportunities for improvement. In improve phase, the researchers
fixed the root causes of the problems identified. The researchers proposed actions to resolve
the root causes. Lastly, in the control phase, it determined the result and capability of the
improvements to make the module inspection section more efficient. As a result, researchers
successfully improved the current system of the module inspection section of PV Tech
Corporation. In Pareto analysis, researchers identified issues such as delays in production,
having defect parts, machine breakdown, and lack of process facility. Using the 80-20 rule,
however, delay in the production and having defect parts had an 80 percent impact on the
process of the module inspection section. The researchers used why-why analysis to identify
the root causes and create a fishbone diagram. To understand the process of the module
inspection section, the flow process chart, flow diagram, operational process chart, and time
study analysis were applied. Lastly, the researchers eliminated every unnecessary operation in
the module inspection section of PV Tech Corporation. With the new system established, the
system was made in such a way that it would improve the quality and the process flow of the
module inspection section.
