Definition of a qualified lead, how it is marked at call-center and how is it marked at sales end, if it's directly patched

Qualified leads are considered in following three cases:

1) Leads in these buckets are counted as qualified: Interested, Meeting done, Visit done, Final negotiation, Booking done

2) When a CC calls a leads and tries to patch an agent, and when the agent doesn’t pick it up, the leads go to Fresh, which then is later claimed by agents - this is also considered as a qualified lead

3) Also call center leads are counted when CC agent marks it as okay with budget/locality/configuration

Qualification % = Qualified Leads / (Total Leads - To Be Qualified Leads)

To Be Qualified Leads (TBQL) -  All new leads that have come to CC for last 3 days and which are not yet processed
