A useful first-90-days plan for a sales development representative should show observable learning, coached practice and increasingly reliable qualification decisions. Write it as learning questions, representative practice, decisions and evidence—not as a promise to hit numbers before you understand the system.
Days 1–30: learn the operating truth
Map customers, offer, workflow, definitions, tools, risks and escalation boundaries. Shadow representative work and compare written process with what actually happens. Agree how success will be assessed and identify which decisions remain supervised.
Evidence of progress includes corrected understanding, completed practice, useful questions and reliable handling of basic records. Raw activity volume is not yet proof of good judgement.
Days 31–60: practise with review
Own bounded work, ask for feedback close to the event and keep a short evidence log. Test one normal case and one difficult case. Record mistakes, corrections and the support boundary rather than hiding them behind a green status.
What must I understand before acting independently?
Makes the learning dependency visible.
Which representative task can I practise safely?
Connects preparation to real work.
What evidence would justify more autonomy?
Prevents confidence from replacing competence.
Which consequence still requires escalation?
Protects customers, colleagues and the business.
Days 61–90: earn a stable cadence
Take ownership of a representative workload, while keeping explicit review points for higher-consequence decisions. Compare outcomes with your original assumptions. Continue what works, reshape weak routines and agree the next development question with your manager.
The plan is complete when you and your manager can see what you learnt, what you can now own, the evidence for that confidence and where support is still required.
Include agreed measures, but label assumptions and dependencies. Early numbers should not imply knowledge you do not yet have.
One page can be enough if each phase names learning, practice, evidence, decisions and review points.
Record the material change and reshape the plan with the accountable manager rather than quietly keeping an obsolete target.
