The Leadership Pipeline Risk: Why Organizations Need to Prepare Managers Before They Lead

By AMA Staff

Organizations depend on managers to translate strategy into performance, develop employees, navigate change, and build strong workplace cultures. Yet many managers step into people leadership roles without the preparation needed to succeed.

According to the 2026 AMA Talent Development Study, 51% of respondents reported being promoted into people management without formal leadership training. The finding points to a significant organizational challenge: Managers are being asked to develop others before they themselves have been adequately developed.

For organizations, this is more than a training issue. It can become a leadership pipeline risk.

The Rise of the “Accidental Manager”

High-performing individual contributors are often promoted because they have demonstrated technical expertise, strong results, or deep organizational knowledge. But succeeding as an individual contributor and succeeding as a people manager require different capabilities.

New managers must suddenly learn how to communicate expectations, coach employees, provide feedback, address performance issues, make decisions, navigate ambiguity, and support the development of others.

Without preparation for that transition, organizations can create what is often described as the “accidental manager”: someone who may be highly capable in their area of expertise but has not yet developed the leadership skills required to manage people effectively.

Why Underprepared Managers Create Downstream Risk

When managers lack the skills or confidence to lead effectively, organizations may experience:

• Inconsistent employee experiences
• Reduced team performance
• Poor communication and feedback practices
• Lower employee engagement
• Increased turnover among high-potential employees
• Weaker succession pipelines
• Reduced organizational agility

Underprepared managers may also spend disproportionate amounts of time responding to performance problems rather than proactively improving team effectiveness.

That creates a difficult cycle. Managers are expected to build capability within their teams, but without adequate leadership development of their own, they may struggle to provide the coaching, guidance, and performance support employees need.

Manager Development Should Begin Before the Promotion

Organizations can reduce this risk by treating management readiness as a deliberate process rather than something employees are expected to figure out once they receive a new title.

Leadership preparation can begin before an employee formally assumes responsibility for managing others. Potential approaches identified in the AMA research include:

• Leadership readiness programs
• Transition-to-management onboarding
• Mentorship and peer support
• Leadership simulations and experiential learning
• Ongoing coaching and reinforcement

Creating a more intentional pathway helps prospective managers understand what people leadership requires, while giving them opportunities to develop and practice those skills.

Manager Development Is Not a One-Time Event

A single management course can provide important skills and frameworks, but effective manager development should continue after the initial transition.

The AMA research points to a broader development model that combines structured onboarding, ongoing coaching and mentoring, practical application, feedback, reflection, and reinforcement over time.

Embedding development into day-to-day work gives managers opportunities to practice new behaviors in real situations. They can apply what they learn, receive feedback, reflect on their performance, and continue building capability as their responsibilities grow.

This also has an important multiplier effect.

Managers who experience meaningful professional development themselves may be better positioned to reinforce development within their own teams. In that way, investment in managers can help establish a broader culture in which learning and performance improvement become part of everyday work.

Building a Stronger Leadership Pipeline

Organizations increasingly expect managers to do far more than supervise work. They are being asked to develop people, facilitate performance, navigate change, strengthen culture, and help employees adapt to increasingly complex workplace demands.

Preparing managers for those responsibilities is part of building sustainable organizational capability.

Organizations that intentionally prepare employees for management—and continue developing them once they enter leadership roles—can create a stronger foundation for leadership succession and employee development.

The central challenge is straightforward: Managers are expected to develop others, but too many are being asked to do so without first receiving sufficient development themselves.

Closing that gap can help organizations build a healthier, more sustainable leadership pipeline.

Frequently Asked Questions

What is a leadership pipeline?

A leadership pipeline is the process through which an organization prepares employees to take on progressively greater leadership responsibilities. A strong pipeline helps ensure that employees moving into management have opportunities to build the capabilities required to lead people effectively.

What is an “accidental manager”?

An accidental manager is someone promoted into a people-management role primarily because of strong individual performance or technical expertise but who has received limited preparation for the responsibilities of leading others. The AMA study found that 51% of respondents had been promoted into people management without formal leadership training.

Why is first-time manager training important?

First-time managers face a significant shift in responsibilities. Instead of focusing primarily on their own work, they must communicate expectations, coach employees, provide feedback, manage performance, make decisions, and develop others. Intentional preparation can help them build those capabilities before leadership challenges become larger performance issues.

What skills should new managers develop?

The AMA research emphasizes capabilities including communication, coaching, feedback, decision making, people leadership, performance management, and navigating change and ambiguity. These skills help managers support both employee development and team performance.

Is one management training program enough?

Manager development should not be treated solely as a one-time event. The research recommends combining structured leadership preparation with ongoing coaching, mentoring, practical application, feedback, reflection, and reinforcement within the daily flow of work.

How can organizations strengthen their leadership pipeline?

Organizations can create intentional pathways into management through leadership readiness programs, transition-to-management onboarding, mentorship, peer support, experiential learning, and continued coaching.
