Manufacturers can involve distributors and retailers in the implementation process by collaborating with them to develop a traceability system that works for everyone. By involving them in the implementation process and also providing adequate training programs, distributors and retailers will feel like they have a stake in the project, making it easier to obtain buy-in. You can also offer incentives to distributors and retailers who comply with the traceability system, such as better pricing, host raffle draws, or other benefits.
