A typical lead lifecycle includes stages like Anonymous Visitor, Known Lead, Marketing Engaged, Marketing Qualified Lead (MQL), Sales Accepted Lead (SAL), Sales Qualified Lead (SQL), Opportunity, and Customer. The exact stages and names vary by organization, but the purpose is always the same: create a shared definition of progress.
The lifecycle model matters because it defines accountability. Marketing owns the stages up to MQL. Sales owns the stages from SAL onward. The MQL-to-SAL handoff is where most friction occurs, and a well-defined lifecycle reduces that friction by making expectations explicit.
MOps teams build and maintain the lifecycle in the CRM and MAP. This includes defining the criteria for each stage transition, building automation to move leads between stages, and creating reports that measure conversion rates and velocity at each stage.
Common lifecycle problems include leads getting stuck in a stage because the transition criteria are too strict, leads skipping stages because the criteria are too loose, and disagreements between marketing and sales about what qualifies as an MQL. All of these are solvable with clear definitions and regular calibration.
Start by documenting your lifecycle stages in a shared document that both marketing and sales leadership sign off on. Include the entry criteria, exit criteria, and SLAs for each stage. Then build the automation to enforce it. A lifecycle that only exists in a PowerPoint deck is not a lifecycle.
