・Feeling limited in fixed-price sales and profit improvement, with sales only generated through sales or coupons.
・Finding it difficult to convey strengths other than price through in-mall measures alone, leading to exhaustion from price competition.
・Advertising, SNS, CRM, and other measures are disjointed, not leading to LTV improvement.
・Wanting to move away from short-term sales generation and build an operational system that leads to fan creation and repeat purchases.
