Supply chain management (SCM) is vital for an organization’s sustainability objectives. This study assesses the SCM practices of a Philippine food manufacturing company, evaluates its organizational sustainability, and examines the relationship between the two. This descriptive-quantitative research used a researcher-structured questionnaire to gather insights from 134 randomly selected employees involved in SCM tasks across various departments of the subject food manufacturing company. The data gathered from the respondents were analyzed using weighted mean, standard deviation, frequency, percentage, and Pearson correlation coefficient analysis. The findings revealed that the company is demonstrating strong performance in all SCM dimensions covered in this study, while the company also showed excellent organizational sustainability in terms of economic, environmental, and social dimensions. The study also found a high significant positive correlation between SCM practices and organizational sustainability, indicating that the excellent performance of a company’s SCM practices directly contributed to enhancing its sustainability outcomes. Based on these findings, several opportunities were identified to further optimize SCM practices and bolster sustainability efforts of the company. This study can offer valuable insights for industry stakeholders to continuously improve their SCM practices in order to drive sustainable operations in the food manufacturing sector.
