Month one of a social selling program is easy to run. New initiative, new energy, everyone posts a few times. The real evaluation question isn't whether a program can launch - it's what has to be true for it to still be running in month four.
The per-rep time cost has to stay near zero, permanently
Any program that asks reps to spend real writing time on posts has a shrinking base of participants from day one - the reps who make time this month may not next month, once pipeline pressure picks up. A program only sustains if the ongoing cost per rep is small enough to survive a busy quarter, which in practice means minutes of review, not an open-ended writing task.
Someone has to be able to see who's still active, without asking
Programs quietly die when nobody's tracking participation until a quarterly review reveals adoption fell apart in week three. A program-wide view that shows who's posting and who's gone quiet - visible before the quarterly report, not discovered at it - is what lets a growth marketer intervene early instead of finding out too late.
There has to be a way to prove it's working, mid-program
A program that can only be evaluated at the end of a quarter has no chance to course-correct. Per-rep engagement data available in real time - which topics land, which reps' content is actually driving replies - lets a program adjust what reps are drawing from mid-stream, instead of waiting for a renewal conversation to find out it wasn't working.
What month four actually looks like when all three hold
A program that's cleared all three conditions by month four looks unremarkable from the outside - which is itself the sign it's working. Most reps are still posting because it's a five-minute weekly task, not a project. The growth marketer running it can pull up a dashboard and answer "who's active" in seconds instead of chasing screenshots. And when leadership asks whether it's paying off, the answer is a specific number - impressions, engagement, which content themes correlate with replies - not a vibe.
None of that requires the program to be dramatic or heavily managed. It requires the mechanics to not silently degrade the way an unmanaged, tool-free mandate does by default.
The failure mode each condition prevents
Skip the first condition (low per-rep cost) and the program shrinks to whoever already liked writing, same as any untooled mandate. Skip the second (visibility into participation) and a growth marketer discovers the shrinkage at the quarterly review instead of in week three, when there's still time to intervene. Skip the third (ongoing proof) and even a program that's actually working can't defend its own budget, since nobody can point to evidence beyond "people seem to be posting."
These three conditions - low per-rep cost, visibility into participation, and ongoing proof it's working - are what separate programs that survive month one from ones that don't.
