The first mistake a new sales leader can make is arriving with the answer before understanding the problem.

There is pressure to make an immediate impact. New dashboards, new meetings, new targets, new methodologies. Activity signals momentum, but premature change can damage what already works.
When entering a sales leadership role, I favour a clear sequence: understand the business, identify its constraints, then build the operating rhythm needed to improve it.
Days 1–30: Diagnose reality
Start with customers, pipeline, people and positioning.
Speak to the CEO and other leaders about growth expectations, economics and strategic priorities. Meet the sales team individually. Listen to sales calls and join customer discussions where appropriate.
Review recent won, lost and slipped opportunities. Examine conversion, opportunity creation, cycle length, forecast accuracy, territories and lead sources.
Most importantly, separate anecdote from evidence. The loudest complaint isn't necessarily the largest commercial constraint.
Output by day 30: a concise diagnostic showing strengths worth protecting, risks that need attention and the two or three interventions most likely to improve performance.
Days 31–60: Establish the foundations
Now make targeted changes rather than launching a wholesale transformation.
Clarify the ideal customer profile and what constitutes a qualified opportunity. Ensure sales stages describe customer progress. Define a consistent approach to discovery and deal reviews.
Introduce a manageable weekly cadence: priorities at the start of the week, focused coaching in the middle and a review of outcomes, blockers and decisions at the end.
Agree a small KPI set, with clear definitions and ownership. Make sure managers understand the difference between inspecting results and developing capability.
Output by day 60: a shared sales operating framework, a credible baseline and specific improvement actions owned by named people.
Days 61–90: Build repeatability
Use the foundations to change behaviour in live opportunities.
Coach against real discovery calls. Improve mutual action plans for strategically important deals. Refine qualification based on what the team learns. Address avoidable delays and strengthen handoffs to implementation or customer success.
Where performance gaps persist, diagnose capability, capacity and motivation separately. Identify hiring needs based on evidence rather than assumption.
Measure leading and lagging indicators, but avoid declaring success from one good week. Look for adoption, consistency and early movement in the right direction.
Output by day 90: a prioritised commercial plan for the next two quarters, with accountable owners, measured assumptions and a working cadence.
What not to do
Don't introduce a complex methodology simply because it worked at your last employer. Don't redesign compensation before understanding behaviour. Don't equate more meetings with better management. And don't dismiss the team's existing knowledge.
A strong leader earns trust by combining curiosity with decisiveness.
The point of the first 90 days
The objective isn't to prove how much the new leader knows. It is to leave the business with a clearer view of reality, better decisions and a system that can continue improving.
A successful first 90 days should make revenue performance more understandable, the team more capable and the next 90 days more purposeful.
