The simulated usage of the proposed design led to the comfortability of the workers in the lowest level based
on Suzanne Rodgers’ Muscle Fatigue Analysis. An improvement of 83.33% is observed in the Strain Index Tool
after the simulation, which means the proposed deboning process is safe. The cost-benefit ratio of the
proposed deboning machine was 1.84, therefore, the investment was acceptable. Keywords: Awkward

The study investigates musculoskeletal discomfort among supermarket cashiers, a profession vulnerable to
musculoskeletal disorders (MSDs) due to repetitive tasks and sustained postures. Conducted at Metro Colon
Supermarket in Cebu City, the research focuses on identifying the body parts where cashiers experience the
highest levels of discomfort. The sample consists of 35 cashiers aged 20 to 48, with 1 to 17 years of
experience, working 6–8 hours daily. Data was gathered using the Cornell Musculoskeletal Discomfort
Questionnaire (CMDQ) to document personal details and areas of discomfort. Additionally, cashiers were
assessed through the Rapid Entire Body Assessment (REBA) tool to evaluate their musculoskeletal risk. The
Analytic Hierarchy Process (AHP) was employed to rank body parts based on discomfort levels. The findings
revealed that tasks such as scanning barcodes, reaching for items, and bagging led to higher REBA scores
compared to other activities. The CMDQ results showed left knee discomfort as the most prevalent, with a
score of 439,452 (8.74%). AHP rankings identified the left foot as experiencing the highest discomfort, with a
weight of 0.15. The study underscores the ergonomic challenges cashiers face in their day-to-day tasks. It
recommends implementing adjustable workstations and ergonomic equipment to reduce discomfort and
mitigate the ergonomic risks cashier’s encounter. These recommendations aim to Keywords:
create measurable improvements in the cashiers' comfort and overall well-being.

Effective document organization is crucial for productivity and quality enhancement to achieve the overall
success of a business organization. In such an industry, there must be a systemized and organized
document management system to reduce the number of backlogs and waste in the workplace. This study
aims to provide a solution to achieve document management without compromising the current system
using Lean Six Sigma principles such as 5S and Kanban. 80% of the inefficiencies in document management
are caused by the inefficiencies of manual filing system. The existing document management processes
that contribute to delays in document management can still be improved through Lean Seven Sigma tools
such as five-sample analysis (SaaS), Kanban, and 5S. The researcher recommends 5S to be utilized in the
current practices to improve productivity, reduce errors, and lower operational costs, thereby optimizing
the document management procedures. Keywords: Document Management, Document Organization, 5S,
