Your CM should be able to provide a path to scale to meet increasing demand for your product, based on forecasted demands but with the flexibility to adapt to fluctuations in demand. They should be able to clearly communicate about current and future processes and have a sufficient number of employees, equipment, and materials to produce larger batches of products. A scalable CM should be able to manage and manufacture multiple models and have efficient shipping practices (drop-ship, direct delivery, etc), as well as have ongoing investment into technology and equipment upgrades.
