External, third-party consultants must bring expertise that enables the solving of a specific issue or series of issues within a set budgetary resource that cannot be addressed internally. Certainly, logistics consulting is one such skillset; it’s a necessary function of most businesses, on which few companies maintain internal experts.
The word “consult” has a Latin root meaning “to discuss,” and that’s all most consultants do – they chatter away until you’ve answered all your own questions, then formalize that input, take credit for it, and send out a bill. Logistics consulting most emphatically does not fall into this category.
As noted, the only time an individual or company really benefits from expert third-party consultation is when highly specialized, technical expertise is a prerequisite and when no internal knowledge-base is available to resolve the problem. Because logistics concentrate on such specific areas, few companies have their own in-house authority.
