Justification for not using lots
The fluctuating nature of potential short-term audit work across locations it was deemed more suitable to have multiple suppliers with full national coverage - still splitting the contract equally, to protect against the risk of having a significant influx of work in a single region which could cause a delay as the allocated lotted supplier may not have capacity. This is a risk-averse approach and has worked previously for Salix.
