Seven Eleven's success in Japan can be attributed to five key factors: offering a one-stop shop for everyday products, cultivating good relationships with customers, quick decision-making by top management, effectively hiring and training employees, and selecting the right store locations. Excellent supply chain management can drive growth by increasing customer satisfaction, product sales, service contract revenue, and margins. As customers place more emphasis on after-sale support, the importance of excellent service supply chains will continue rising in the future.
