At JRG Partners, we compiled this ranking from what we see across executive searches, so it reflects practice rather than theory. A strong executive hire can still fail if onboarding is botched, and some onboarding mistakes do far more damage than others. This list ranks twelve onboarding mistakes by how much they damage a new executive’s success, from the most damaging to the merely harmful, so employers can avoid the errors that most often doom good hires.
Key Takeaways
- A strong hire can fail if onboarding is botched.
- The most damaging mistakes involve poor integration and unclear expectations.
- Neglecting relationships, context, and support undermines new executives.
- Onboarding mistakes, not hiring mistakes, doom many good hires.
- Avoiding the high-damage errors protects the investment in the hire.
Why Onboarding Makes or Breaks the Hire
Many executive failures are onboarding failures, not hiring failures: a strong hire, badly onboarded, can fail, while good onboarding sets even a stretch hire up to succeed. Some onboarding mistakes do far more damage than others. Below are twelve, ranked by how much they damage a new executive’s success, so employers can focus on avoiding the high-damage errors that most often doom good hires.
The 12 Mistakes, Ranked by Damage
1. Leaving the executive to sink or swim
Most damaging: providing no real onboarding, support, or integration and expecting the executive to figure it all out. Sink-or-swim onboarding dooms even strong hires and is the costliest mistake.
2. Unclear or misaligned expectations
Highly damaging: the executive and company are not aligned on what success looks like or what the role requires, so the executive works toward the wrong things. Misaligned expectations undermine the hire from the start.
3. No early alignment with the manager or board
Failing to align early with the manager (CEO or board) on expectations and the relationship leaves the executive without direction and support, a highly damaging omission.
4. Pressuring the executive to act before understanding
Pushing the executive to make big moves before they understand the situation leads to avoidable mistakes and alienation. Demanding premature action is very damaging.
5. Neglecting relationships and stakeholder integration
Failing to help the executive build the key relationships and integrate with stakeholders leaves them without the support and trust their success depends on, seriously damaging integration.
6. Failing to provide context and information
Not giving the executive the context, information, and access to understand the real situation forces them to operate blind, a damaging handicap early on.
7. Ignoring cultural integration
Neglecting to help the executive integrate into the culture, especially in a skeptical or established team, leaves them an outsider, undermining their effectiveness.
8. No structured plan for the first 90 days
Without a structured first-90-days plan, the executive’s critical early window is wasted or misused, reducing the effectiveness of their start.
9. Poor communication about the hire
Failing to communicate the hire well internally, or sequencing it poorly, creates a weak first impression and unsettles the team the executive will lead.
10. Overloading the executive immediately
Piling on demands and responsibilities before the executive has oriented overwhelms them and prevents the learning a strong start requires.
11. Neglecting basic setup and logistics
Failing to complete basic setup, access, tools, workspace, signals disorganization and hampers the executive’s start, a smaller but real damage.
12. No check-ins or early feedback
Not checking in or providing early feedback means problems go unaddressed and the executive lacks course-correction, a harmful but more recoverable omission.
The Bottom Line
The onboarding mistakes that most damage new executives, sink-or-swim onboarding, misaligned expectations, no early manager alignment, and pressuring premature action, doom good hires more than hiring mistakes do, so avoiding the high-damage errors protects the investment in the hire. Use this list to sharpen your thinking, then adapt it to the specifics of your company and your hire.
