In terms of sharing information, the authority should be careful to differentiate between information which should be considered commercially sensitive (e.g. any information which a supplier has provided to the authority and which it may consider provides them with a ‘competitive edge’ such as indicative pricing and solutions provided to other customers which may not constitute public knowledge etc.), and information which should be circulated to all bidders (e.g. information produced by the authority to describe the opportunity such as outline business cases, draft specification etc.).
In terms of sharing information about whether the authority’s requirements are tech agnostic, such information would appear to fall into the latter category, ie, it should be shared with all bidders.
