ACKNOWLEDGEMENTS
First and foremost, I would like to thank my instructor, Professor Nguyen
Khac Hieu, for his unwavering support, encouragement, and guidance
throughout the entire research process—from coming up with the topic and
recommendation to coming up with solutions to proofreading the thesis. To
complete an internship report under his guidance and knowledge is an
enormous honor. I sincerely appreciate the chance to work on new projects
that are pertinent to my needs, Professor Nguyen Khac Hieu. Additionally, I
want to convey my gratitude for your insightful criticism and motivational
language use.
I will always remember to thank PepsiCo Food Vietnam for providing me
with the chance to work as a QA intern, especially Mr. Vu Nguyen and Mr.
Chau Nguyen, having trained and supported me throughout the past six
months. It’s definitely an unforgettable time to me, which helps me improve
myself significantly on mindset, knowledge and skills.
With all experiences and chances of working with these excellent
individuals, my goal is to finish the report with the most workable
recommendations to improve performance and efficiency in addressing
quality-related complaints at PepsiCo Food Vietnam.
