Promising a date without booking the necessary resources can generate overlap. The firm needs to know which capabilities are already engaged and which remain available. A calendar that only shows the final deliveries can leave invisible previous processing and verification.
It is advisable to link every promise to indispensable materials, people and passages. A provisional availability should be distinguishable from a confirmed one. When a customer information is missing, the date requires an understandable condition and a subsequent confirmation, consistent with the agreements made.
In a hypothetical example, two orders can only be delivered in the same week using the same machine on the same day. The criticality emerges from the processing schedule. Early communication makes it possible to discuss alternatives before both promises become difficult to keep.
I propose to check the modified dates and the recurring causes. Control should improve the transition between sales and production. A reliable promise depends on the quality of the information shared and how the company reserves the resources to achieve it.
