Underperformance gets diagnosed as a skills gap far more often than it is one. The tell is variance: a training problem produces consistently weak performance across the team, while a system problem produces wide variance between individuals doing nominally the same job.
The variance test
Rank your sellers by close rate. If the spread between best and worst is narrow and low, the team does not know how to do the job - that is training. If the spread is wide, the top performer has built a private system that the organisation never captured, and the rest are improvising. That is a system problem, and no amount of training will fix it while the process stays undefined.
A wide spread between your best and worst seller is not a people problem. It is evidence that your process lives in one person's head.
Three further diagnostics
- Ask three sellers to describe the qualification standard. Three different answers means there is no standard.
- Look at where deals die. Deaths clustered at one stage indicate a system gap; deaths scattered across every stage indicate a capability gap.
- Check whether the CRM describes what happened or what must be true next. Descriptive stages cannot run a process.
The right order
Define the process first, then train against it, then coach until the rhythm holds without you. Reversing that order produces a team that is briefly enthusiastic and permanently inconsistent.
