Founded in 2005, the Pérola Supermarkets Chain has gone from one to three stores and plans to open its fourth in 2019. Since its founding, the chain has improved the structure of all three stores it has purchased, in addition to the adoption of a complete specific management software for the supermarket sector. During the current stage, as competition increase, the chain must look for new ways to differentiate itself and create a competitive advantage. Through surveys and interviews with customers, employees and management of the chain, it was possible to analyze the environment and identify possible points of improvement. After the analysis, the implementation of a loyalty program for the customers was suggested, seeking to improve its performance in addition to seeing new opportunities. Customers registered in the program will have access to discounts and promotions, and also participate in exclusive events and contests. Among the expected results, the program aims to increase the average ticket price, generate loyalty, as well as being a differentiation tool over competitors. Finally, it was concluded that the program has the potential to meet certain difficulties faced by the chain and is an interesting resource for it.
