The first aspect is accurate category management. The main goal of fast fashion is to quickly develop and produce products that meet customers' needs in a cost-effective way. As a brand, you need to analyze and find the category that you are best at, easy to meet the needs of customers and the best profit. In order to achieve this goal, it is necessary to coordinate the marketing department, development department and external partners to grasp and analyze sales data in time. Therefore, there must be a flexible and efficient information system to support it, so that all participants can develop and manage categories with high profit margins accurately and quickly based on a unified and efficient exchange and cooperation platform.

The second aspect is the rapid response supply chain. The focus of fast fashion is "fast", but it must also be "fast" without chaos. There are two kinds of supply chains: agile and lean. The principle of agile supply chain is to share information and technology with all partners in the supply chain in real time and reduce inventory through close cooperation; The core feature of lean supply chain is to deliver the right products at the right time. A fast and fashionable supply chain needs to combine them organically to form a lean supply chain. Therefore, we must improve and simplify the whole process from product concept, design, development and proofing to production and logistics distribution. After the improvement and simplification of the process, the rapid response supply chain has realized the increase of value and the reduction of cost, and at the same time, it has received timely feedback on the changes of customer needs. To realize a "lean" supply chain, it is necessary to adopt the current advanced software technology to support the smooth operation of the whole business process, so as to ensure the accurate and real-time execution of the process and data, and not to miss or delay any details of the process and data.

The third aspect is supplier relationship management. Fast fashion brands need to establish a good and extensive partnership with suppliers. Suppliers need to keep up with market demand and fashion trends together with brands, and need to participate in the design and development stage of products. In order to ensure smooth communication and close cooperation, it is best to have a unified communication and cooperation platform, and then all partners can run every business process efficiently based on the platform and accurately record every data detail.

The fourth aspect is internal relations. As important as maintaining a good external supplier relationship, it is necessary to have a coordinated internal relationship. Many organizational structures are divided according to different functional departments, such as marketing, design, procurement, production and quality inspection. Communication, cooperation and information sharing between functional departments are always unsatisfactory. To effectively implement the fast fashion business strategy, we must have close relationship and quick market response ability. This requires a unified information system to ensure timely communication and close cooperation.
