These benefits only accrue whilst the green stream/FRS products or services remain predictable in demand. Therefore it is critical to ensure appropriate frequency reviews of product demand to ensure promotion of stable products from the red stream and demotion of now less stable demand products to the red stream.
These benefits emerge only if green stream/FRS products or services have consistent demand levels. Thus, it is vital to conduct periodic reviews of product demand to ensure that stable products remain in the red stream while less stable demand products are moved there.
