SDR manager first 90 days: learn, stabilise, improve

A new SDR manager is suddenly responsible for other people's results, pay and development. And they're still learning the job. A plan stops you changing everything on day one or drifting for three months. Split the first 90 days into three phases: learn, stabilise, improve.

SDR (sales development representative) and BDR (business development representative) are the same job at most companies. Everything here applies to both.

This plan is for you as the manager. For your reps' own first 90 days, use our SDR onboarding checklist.

Before day one

Free: the SDR KPI Cheat Sheet. The KPI tree, 15 sourced benchmarks, an early warning checklist and a capacity model. Two printable pages. Get it free

Days 1 to 30: learn

Understand the team and the system, and build trust. People are watching to see who you are, so hold off on big changes.

Avoid: announcing a new plan, changing pay, criticising your predecessor or rewriting the scripts.

By day 30 you can describe the funnel and each rep's strengths and gaps. You can name the three or four biggest issues, with evidence.

Days 31 to 60: stabilise

Fix the basics and make the team's operating rhythm reliable.

By day 60 the team knows what you expect and how they're measured. They know how they'll be coached. For what to put on the scorecard, see our SDR and BDR KPIs guide.

Now start to put your own mark on the team. Base it on what the first two months showed you.

By day 90 you've presented your read on the team. You've also shared a plan for the next quarter, with evidence.

WeeksFocus
1Meet your manager, review dashboards, meet two sales partners and hold the first three rep 1:1s
2Finish rep 1:1s, listen to six recorded calls and read the comp plan. Write a one-page summary of what you've learnt
3Start the weekly 1:1 rhythm, meet marketing and shadow a live outbound session. List five issues with evidence
4Rank the issues with your manager and agree the top two
5 and 6Work on issue one, for example a meeting confirmation step, and measure the held rate
7 and 8Work on issue two and start the weekly scorecard in a fixed format
9 and 10Test one change to messaging or ramp with two reps first
11 and 12Review progress with each rep, write the next-quarter plan and present it

Common traps

Questions

What should a new SDR manager do in the first 30 days?

Listen and learn. Hold a 1:1 with every rep in the first two weeks, and review calls. Learn the comp plan, quotas and dashboard. Meet sales and marketing partners. Hold off on big changes.

What should a new SDR manager fix first?

The two or three issues from month one with the most evidence behind them. Typically lead quality, meeting confirmation, inbound follow-up speed or handover rules with sales.

When should a new SDR manager change the comp plan?

Not in the first month, and never mid-period. Model the effect of any change on last quarter's results first. Then propose it for the start of the next period.
