Why is an inherited sales team hard to judge?
An inherited team arrives with a verdict already attached. The last leader's rankings and last year's attainment report reach you before you meet anyone.
Social psychologists call the pull toward reading results as character the "fundamental attribution error." Lee Ross coined the term in 1977 for the tendency to underestimate situational factors and overestimate dispositional ones. Scholars still debate how universal it is.
In sales, part of that situation is the territory. In 2004, ZS Associates, the consulting firm of Andris Zoltners and Prabhakant Sinha, reported that its territory alignment projects had led to revenue increases of 2% to 7% for client companies. That is the firm's own account of its own work.
A wrong exit has a price too. Gallup estimates that replacing one employee costs one-half to two times annual salary and describes that range as a conservative estimate. The 2019 figure has no breakdown for sales roles.
What questions help you assess an inherited sales team?
Six questions, and one that sits under all of them.
-
Is this result the person, the territory or the plan they were given?
Quota attainment is a fact about a period. It blends the seller's work with the book they inherited, the quota someone set and the manager they reported to. Ask what the territory held on the day they took it, and listen for whether anyone can tie the quota to the accounts behind it. A strong number on a rich book and a modest number on a thin one can reflect the same effort.
-
What do I see when I watch this person work a real deal?
Reports tell you what happened, and watching tells you how. Join a site walk, a bid review or a renewal meeting, and pay attention to what the seller does before and after the customer is in the room. Listen for what the buyer has agreed to do next and why the buyer would act this quarter. One deal is a small sample, so see more than one before you settle on a view.
-
Which managers inspect deals and which just report them?
Gallup estimates that managers account for at least 70% of the variance in employee engagement scores across business units. That finding covers engagement and gives no direct read on sales results. In a pipeline review, listen for questions the CRM could not have answered and for forecasts that move after the front-line manager looks at a deal. A manager who reads the system back to you may be doing what the last leader asked for.
-
Who do customers ask for by name?
Customer trust is evidence nobody can stage for a new leader. When you meet your largest accounts, ask who they work with and who they would want on the next project. A name that keeps coming up tells you where the relationships live, and that matters before you move a territory or change a role. Silence can mean a recent handoff, so check the account history before you read anything into it.
-
What do the people on this team say is in their way?
Ask each person, one to one, what slows them down and what they would change first. The answers describe the system the team works inside, from pricing approvals and quote turnaround to handoffs with operations. When several people name the same obstacle, that is a fact about the operation before it is a fact about any one of them. Asking also shows the team how you plan to form your views, which is fair to them.
-
What would it cost to wait 60 more days before making a change?
Waiting can cost deals and customer goodwill while a gap stays open. Acting early can cost you someone customers trusted, plus the time and money to hire and ramp a replacement. Put both costs on paper for each change you are weighing, and listen for the cost that the people pushing for speed leave out. Conduct problems and harm to a customer sit outside this question and get handled when you find them.
"Which people decision am I about to make on opinion alone?"
Ask yourself this before you change anyone's role or territory. Name the evidence behind the decision and where it came from. If it rests on a secondhand account or a first impression, go and see the work. The goal is a decision you could explain to the person it affects.
How can you tell if your read of an inherited team is sound?
Good signs
- Your view of someone has changed since you arrived, in either direction.
- You can point to a live deal you watched behind each view you hold.
- Sellers have told you what gets in their way, and some of it was about the system.
- You know which results came with a strong book of existing customers.
- Managers bring you deals they changed their minds about after a review.
Warning signs
- Your strongest opinions about people came from someone else before you met them.
- Last year's attainment report is the only evidence you hold on someone.
- Your first-week view of each person has not moved since.
- A manager's pipeline review repeats what the CRM already shows.
- The team hears about changes through rumor before they hear it from you.
Case study Fictitious numbers
A new VP Sales joins a PE-backed fire and life safety services company with 14 sellers across three branches. Last year's report shows two sellers at opposite ends. Seller A booked $1.56 million against a $1.2 million plan, 130% of quota. Seller B booked $700,000 against a $1.0 million plan, 70% of quota. The prior leader's notes mark B for replacement.
- Renewals and repair on sites already under agreement
- New customers and won bids
- Each seller's plan
The attainment report puts A at the top and B at the bottom. On new business alone, B booked $240,000 more than A.
The territories explain much of the gap. A's branch holds the largest base of inspection and service agreements. Of A's $1.56 million, $1.1 million came from renewals and repair work on sites already under agreement, and $460,000 came from new customers. B took over a territory with few agreements, so all $700,000 came from new agreements and won bids. On new business alone, B booked $240,000 more than A.
The split changes the questions the VP needs to ask about both sellers. The VP holds off on any change for 60 days and joins each of them on live bids and renewal meetings before deciding whether a role or a territory should move.
FAQ
How long should you wait before changing an inherited sales team?
Wait as long as the evidence takes. That means long enough to watch each person work live deals and to see each manager run more than one review. The right length differs by person, so compare the cost of waiting with the cost of a wrong change one decision at a time. Conduct problems and harm to a customer get handled right away.
How do you tell if a sales rep's results come from the territory?
Look at what the territory held when the seller took it over. Compare the share of bookings that came from existing agreements and renewals with the share that came from new customers and won bids. Ask how quota was set and whether it moved with the accounts. Two sellers with the same attainment can be doing different work, and territory design is a decision the company made.
How do you assess sales managers you inherited?
See them in the meetings they already run, more than once, before you form a view. Ask their sellers what the manager helps them with, and compare the answer with what you saw. Say plainly what you expect a review to surface, and give each manager a fair chance to show it before you decide.
Should you tell the team you are assessing them?
Yes. A team expects a new leader to form views, and silence feeds rumor. Tell them what you will look at, such as live deals and customer relationships, and that you will take time to see the work firsthand. Clear expectations make the assessment fairer and give each person a chance to show their work. Keep individual conclusions private until you have talked them through with the person.
