OEM involves manufacturers designing products to a customer's specifications, allowing limited customization and rebranding. ODM involves customers designing their own products and working with design houses for development. Neither OEM nor ODM is strictly better - they each have advantages depending on business needs and strategy. OEM is faster with shorter timelines and lifecycles but weaker brands, while ODM enables stronger brands and innovation with longer timelines. Companies should analyze their market approach, resources, and goals to determine the most suitable production model between pure OEM, pure ODM, or a hybrid approach.
