Talent Strategy: When to Promote and When to Hire

The decision between promoting internal talent or seeking it externally isn’t a simple cost dilemma; it’s one of the most important strategic levers for your business’s growth and stability. A wrong choice can slow innovation, deteriorate culture, or inflate budgets. The question isn’t which is better, but which responds to the specific needs of the vacancy, the team, and the organization at this moment. Aligning this decision with business objectives is fundamental to building solid and agile teams.

Recruitment is no longer about filling seats. It’s about a calculated allocation of human capital. A strategic approach means understanding that internal mobility strengthens culture and retains institutional knowledge, while external hiring injects new competencies and perspectives. Ignoring either path limits the organization’s potential. That’s why the real challenge is building a system that allows making the best decision in each case, based on data rather than assumptions.

Fundamentals of organization-centered recruitment

Before comparing methodologies, it’s crucial to establish that both are tools in the same arsenal. Internal recruitment leverages existing human capital, promoting employees who already know the culture, processes, and key people. This includes vertical promotions, lateral transfers, or creating hybrid roles. On the other hand, external recruitment seeks talent in the general market through platforms, agency partnerships, or direct search, aiming to attract competencies that don’t exist within the company. Both paths are necessary for sustainable growth, and the key is knowing when to activate each one.

Strategic advantages of internal mobility

Fostering growth from within is more than a cost-saving measure; it’s a direct investment in culture and retention. When employees see clear career paths, their commitment and productivity increase.

1. Accelerated Time-to-Impact: An internal employee already knows the systems, culture, and key players. Their learning curve is significantly shorter, allowing them to generate value almost immediately in their new role.
2. Reduced Cost per Hire (CpH): Eliminates direct expenses like job portal postings, agency fees, and recruitment marketing costs. According to studies, savings can reach up to 50% compared to an external hire.
3. Strengthened Culture and Commitment: Promoting internally sends a powerful message: the organization invests in its people. This improves morale, fosters loyalty, and reduces voluntary turnover rates.
4. Lower Risk of a Bad Hire: The candidate’s performance and cultural fit are already known. The surprises that often arise after the first months of a new external employee are eliminated.
5. Retention of Critical Institutional Knowledge: Prevents experience and accumulated knowledge about clients, processes, and past mistakes from leaving the organization.

The value of new perspectives from external talent

While internal promotion is safe, long-term growth often requires an injection of new ideas, skills, and experiences. External talent is the catalyst for innovation and market adaptation.

1. Access to New Competencies and Skills: Allows incorporating profiles with experience in emerging technologies, new markets, or methodologies that don’t exist internally.
2. Boost to Innovation and Diversity of Thought: A new member can challenge “we’ve always done it this way,” breaking silos and fostering creativity with fresh perspectives.
3. Expansion of Available Talent Pool: The external market offers a much larger universe of candidates, increasing the chances of finding the exact profile for a highly specialized role.
4. Resolution of Accelerated Growth Needs: When a company expands rapidly, external recruitment is the only way to scale teams at the speed the business demands.
5. Sending Competitive Signals to the Market: Hiring a recognized industry leader can improve employer brand positioning and attract more high-caliber talent.

The hidden cost no one measures in each decision

The choice between promoting or hiring goes beyond obvious expenses. Each path has hidden costs that directly impact productivity and culture. Ignoring them means making a blind decision.

In internal recruitment, the main hidden cost is the “domino effect”. When you promote someone, you create a new vacancy: the one that person left. Now you have to fill that second position, generating a chain of movements that consumes time and resources from multiple team leaders. Another cost is stagnation. An overreliance on internal talent can lead to thought homogeneity, reducing the company’s ability to innovate and adapt to market changes.

For external recruitment, the most underestimated cost is cultural dilution. A new employee, no matter how competent, may not adapt to the company’s values and unwritten ways of working. Poor adaptation can generate conflicts, demotivate the existing team, and in the worst case, end in premature departure, doubling the hiring cost. Additionally, there’s the cost of lost productivity during the learning curve, which can extend from three to six months, a time when the new team member consumes more resources than they generate.

Creating a hybrid model: the 70-20-10 framework

A mature talent strategy doesn’t choose sides but builds a deliberate hybrid model. The 70-20-10 Framework is a balanced approach that aligns recruitment with business objectives:

• 70% of vacancies are filled internally: This should be the foundation. Prioritize promotion and lateral mobility for operational roles, middle management, and senior specialists. This creates a development culture, stabilizes operations, and maximizes knowledge retention. It requires a robust performance evaluation system, career plans, and transparent communication of opportunities.
• 20% are filled externally for specific skills: Allocate this portion to roles requiring technical or specialized competencies that don’t exist in the organization. These could be cybersecurity experts, data analysts with experience in new software, or digital marketing specialists for a new channel. This approach ensures the company remains current and competitive.
• 10% are filled externally for leadership or transformation roles: Reserve this small but critical portion for high-impact positions, such as directors or leaders of new business units. The goal here is to inject strategic vision, challenge the status quo, and lead cultural or market changes. An external leader can bring a network of contacts and a perspective impossible to cultivate internally.

Strategic closure of the talent decision

The choice between internal and external recruitment isn’t a battle of “one against the other” but a strategic dance requiring balance and vision. Internal promotion is the pillar of a solid culture and knowledge retention, while external hiring is the engine of innovation and adaptability. No organization can prosper long-term without a healthy flow of both. Adopting a reactive approach, deciding case by case without a framework, is a recipe for inconsistency and missed opportunities.

Conclusion: a talent ecosystem, not a pipeline

The ultimate goal is to stop viewing recruitment as a pipeline that opens to fill a gap and start seeing it as managing a talent ecosystem. A healthy ecosystem cultivates its own talent through career plans and mentoring while enriching itself with the cross-pollination of ideas and skills from outside. Implementing a conscious hybrid model, like the 70-20-10 framework, allows organizations to be proactive, agile, and strategic in managing their human capital, turning recruitment into a true competitive advantage.
