The inventory is only as good as the data put into it. Okamura (2004) noted in his paper that real-time inventory management is the process of recording sales and purchases of inventory immediately. Often, jewelers count inventory periodically which causes a delay in recording stock status. Today, buyers expect same-day delivery. Same-day delivery combines the convenience of online shopping with the immediate product access of stationary retail (Hausmann, Herrmann & Krause, 2014). It integrates the convenience of online retail with the immediacy of bricks-and-mortar stores. (Hausmann, Hermann, & Krause, 2014). Technologies like mobile applications can be a great solution to this kind of problem. Mobile applications are running on a small handheld mobile device which is moveable, easy to use, and accessible from anywhere and any place (Islam & Mazumder, 2010). It will enhance the customer experience. Sales agents can be more responsive to customer requests where they must provide when and where the item is available. The objective of this study is to create a mobile application design application using Tondreau's principles for Twin Princess Gems' staff to help keep the inventory database up-to-date on the current location of the jewelry. This study will find the most intuitive way of designing a mobile application for updating jewelry location.
