Marketing and finance departments want to know who their loyal/profitable customers are. Presidents, CEOs, VPs and corporate executives and shareholders want the best returns on their investments. They want to see their online grocery companies turning profits and maybe even making innovations. Who will buy what product? Which channel is more profitable- digital or non-digital? Which demographic group is most productive for sales? How much influence do rewards have on sales? How effective are email campaigns on sales? How can the data be mined to cross sell and thus exploit hidden relationships in the data, to gain competitive advantage in customer retention? The data is made up of continuous and nominal variables. I will analyze this transactional, demographic and geographic data with a goal to glean insights to help this grocery business to increase preorder penetration and density in orders so as to optimize truck routing and maximize sales.


I will like to express my heartfelt and utmost gratitude to Chair Dr. Shiju Zhang – your patience, leadership and feedback miles away from me was crucial and very much appreciated. You are amazing.

Dr. Hui Xu and Dr. Richard Sundheim. You took time out of your busy personal and professional life to guide me in this journey. I am forever indebted to you.

Dr. Leonard Onyiah – you welcomed and challenged me from day one and have always been a sounding board. Thank you most kindly!

I also owe a huge debt of gratitude to Dr. David Robinson for providing in-depth insight and feedback, mentoring me and helping to bring out the best in me.

I will be remiss if I forgot to thank my friend and peer, Zhengyi Li for reading over this and giving me some very insightful feedback.

Thanks a ton to Renee for mentoring me and believing in me. Thanks also to Kobbie Opoku Adu-Gyamfi for critical feedback and insight. Thank you to my friends and course mates – Mahesh Rimal and Lynda Smith for your encouragement and feedback.

Thanks to my parents, Ben and Doris Ahlijah and siblings, Shirley-Ann, Ben JR, Dorothy and Nancy and many who supported me in this journey. Thanks to my spouse and partner April for supporting me and believing in me when times were tough.

I give Glory to God and prayers of thanksgiving and praise to him for giving me the fortitude, grace and strength to press on toward the goal.
