Full launch: when it makes sense
Full launch (program announcement, tier structure, partner portal, public partner directory) makes sense when: you have prior experience running partner programs and know the motion will work at your stage, the program is core strategy approved by executives, you have a named partner manager with 50%+ of their time committed, and you need partner-sourced revenue inside 12 months.
Full launches signal commitment to partners (who weigh program credibility before investing their time) and force internal alignment (legal, marketing, ops have to ship things on a deadline).
Pilot: when it makes sense
Pilot (2-5 partners, no public announcement, minimal documentation) makes sense when: your direct sales motion is still being refined, you are uncertain which motion will work, executive sponsorship is exploratory rather than committed, or your team has no prior partner experience and needs to learn.
Pilots preserve optionality. If the motion does not work, you have not made public commitments you need to retract. If it does work, you have evidence to justify a full launch.
Failure modes of each
Full launch failure modes: over-committed infrastructure that produces nothing (PRM, tiering, MDF) while you discover the motion does not fit; partners frustrated by program changes you have to make publicly; executive patience runs out before revenue materializes.
Pilot failure modes: pilots that never graduate (perpetual exploration mode); insufficient investment to give the motion a fair test; lack of public commitment makes serious partners skeptical of working with you.
Hybrid: "soft launch"
The pattern most successful programs actually use: announce a small initial cohort publicly ("we are launching a partner program; here are our first 5 partners") with explicit framing that the program will evolve. This gets the credibility benefit of public commitment while preserving the optionality of pilot mode.
Soft launch works because it is honest about where you are. Partners appreciate the candor; executives get visible progress; the team gets latitude to learn.
What documentation each needs
Pilot: mutual NDA, simple agreement for the chosen motion, commission terms, basic deal registration form. The Referral or single-motion pack covers this.
Full launch: all of the above plus tier structure, certification curriculum, MDF policy, channel conflict policy, internal RACI, partner portal requirements, scorecards. The Full Library covers this.
Soft launch: middle ground — pilot documents plus a tier exhibit you can revise, plus channel conflict policy before the first partner signs.
