What Is a Development Assignment? Growing Internal Successors Deliberately

As Global Head of Research & Leadership Advisory at JRG Partners, I have written this plain-English explainer because the question comes up in nearly every client conversation. A development assignment is a deliberately chosen role, project, or experience given to a high-potential leader to build specific capabilities they need for future roles. It is one of the most powerful tools for developing internal successors, because leaders grow most through stretching real experiences, not through training alone.
What follows is the practitioner’s version: the definition, how it actually operates, where it is commonly misunderstood, and what employers should take from it. It is written for people who have to make decisions with the concept, not merely recognize the term.

What a Development Assignment Is

A development assignment is a purposeful experience, a stretch role, a challenging project, a rotation into an unfamiliar function or geography, given to a promising leader specifically to build capabilities they lack but will need. Unlike routine assignments, it is chosen deliberately for its developmental value, targeting the specific gaps between where the leader is and where they need to be for future roles.

Why Development Assignments Work

Research and experience consistently show that leaders develop most through challenging experiences, not classroom training. A well-chosen development assignment forces a leader to build new capabilities under real stakes, general management, cross-functional leadership, turnaround, scaling, in ways no course can replicate. It is the primary mechanism by which high-potential leaders are prepared for larger roles, which is why deliberate assignment is central to succession development.

How to Design Development Assignments

Effective development assignments start from the gap: what capabilities does this leader need for their likely future roles, and what experience would build them? The assignment should genuinely stretch, real stakes, unfamiliar territory, while providing support to succeed. It should be chosen deliberately, not left to chance, and paired with reflection and coaching to extract the learning. The art is matching the assignment to the specific development need and the leader’s readiness.

Using Assignments in Succession Development

Development assignments are the engine of building internal successors: a company that identifies high-potentials and deliberately routes them through the experiences that build the capabilities its future leadership roles require creates genuine readiness, not just names on a succession chart. This requires planning assignments years ahead of need, accepting the short-term cost of stretching people, and treating experience as the primary development tool. It is how replacement planning becomes real succession.

How It Works in Practice

In practice, a company developing a high-potential leader identifies the capabilities they need for future roles, then deliberately assigns them experiences that build those capabilities, perhaps a P&L role to build general-management skill, a turnaround to build decisiveness, or an international assignment to build breadth. The assignment stretches the leader under real stakes, with support and coaching to extract the learning. Over time, a sequence of such assignments builds the genuine readiness that prepares internal successors for larger roles.

Why This Matters for Employers

Development assignments are the most powerful tool for building internal successors, because leaders grow most through stretching experiences, not training alone. Understanding how to design and use them deliberately helps companies build genuine leadership readiness rather than merely naming successors who are not actually prepared.

Common Misconceptions

The misconception is that leaders are developed primarily through training programs. Research shows they develop most through challenging real experiences; development assignments, deliberately chosen stretch roles and projects, are the primary mechanism, with training a supporting complement.

A Practical Example

Consider a company grooming a functional leader for eventual general-management responsibility. Rather than sending them to a course, it gives them a development assignment: running a small business unit with real P&L accountability. The stretch forces them to build the cross-functional, commercial, and decision-making capabilities general management requires, under real stakes. When a larger GM role later opens, the leader is genuinely ready, prepared by experience rather than by a name in a succession box. That readiness is exactly what development assignments create.

The Bottom Line

Understanding Development Assignment precisely, what it means, how it differs from adjacent concepts, and when it applies, helps employers and boards make cleaner decisions about structure, hiring, and accountability. For senior roles, that precision is not pedantry; it is what keeps expectations, contracts, and reporting lines aligned from day one.
