DBI items experience a demand frequency of two or more in a period of six months and continue to have at least one demand every how many months afterwards?

DBI items, or Demand Based Items, are classified based on their demand frequency over a specific period. For items to qualify and maintain their status as DBI, they must have a demand frequency of two or more in a period of six months and continue to have at least one demand every six months afterwards.

The reasoning behind this requirement is to ensure that these items are relevant and actively needed within the logistics framework. Maintaining at least one demand every six months helps to confirm that there is enough ongoing interest or necessity for the item, justifying its stock and ensuring that logistics operations are effective. If the demand were to drop below this threshold, it may indicate that the item is no longer necessary, leading to potential stock adjustments or discontinuation.

In this context, the correct option reinforces the importance of continual demand to assess inventory obligations and inform future logistical decisions. Therefore, the choice of six months aligns perfectly with the established criteria for sustained demand frequency in logistics operations.
