Which strategy involves the retailer developing a new format for the same target market?

The strategy that involves a retailer developing a new format for the same target market is retail format development. This approach focuses on innovating or modifying the existing store's layout, design, services, or product offerings to enhance customer experience and better meet the needs of the target audience. By creating a new format, retailers can attract new customers or encourage existing customers to visit more often, thereby improving sales and strengthening their market position.

When a retailer engages in retail format development, they may introduce changes such as a new store design, expanded product lines, or new service options while still appealing to the same demographic. This strategy is particularly effective in addressing evolving consumer preferences or competitive pressures, enabling the retailer to remain relevant in the market.

Other strategies like diversification, market expansion, and market penetration focus on different aspects, such as entering new markets, increasing market share in existing markets, or introducing new products. However, they do not emphasize the modification of the retail format directed towards the same target audience.
