Pitfall 1: No Clear 30-60-90 Goals
Augmented devs drift without specific milestones. Define success metrics: "Ship 5 PRs in Month 1, own payments module in Month 2, mentor junior in Month 3."
Pitfall 2: Treating Them as Outsiders
If they're excluded from team socials or decision-making, engagement drops. Invite them to Friday demos, retrospectives, even virtual happy hours.
Pitfall 3: No Dedicated Mentor
Leaving them to "figure it out" adds 2-3 weeks to ramp-up. Assign a mentor who commits 5-8 hours in Week 1, then 2-3 hours/week after.
Pitfall 4: Forgetting Offboarding
If the contract is 6 months, start offboarding prep at Month 5: documentation, access revocation planning, knowledge transfer sessions.
