Yes. Traditionally, the government does most of its procurement during a period of roughly three months every year. That's well known in the industry,
the crazy month of March.
That requires large production capacity on the industry's part, in very short timeframes. So if an SME got a very big contract for the government as a whole, it would have to produce four times as much over three months, then subsequently dismiss everyone, then do the same thing the following year.
