Leadership is one of the strongest predictors of workforce performance. It is also, by current research, in visible crisis.
DDI’s Global Leadership Forecast 2025, the largest and longest-running global leadership study (spanning over 50 countries and more than 10,000 leaders), found that trust in immediate managers has fallen to just 29%, down from 46% in 2022. It reported that 71% of leaders report increased stress, with 40% of stressed leaders having considered leaving leadership roles entirely. The same study found 77% of CHROs lack confidence in their bench strength for critical roles.
Most organizations still develop leaders the way they did twenty years ago: a generic workshop, a book, and the hope that people figure it out. The data on manager trust and burnout suggests that approach is failing at scale.
Industrial-Organizational (I-O) Psychology offers an alternative: developing leaders using assessment, measurement, and behavioral science instead of one-off training. At Invictus Strategy & Solutions, our team of I-O Psychologists applies this approach systematically rather than as a single workshop event.
Why Leadership Gaps Are a Top Driver of Workforce Failure
Leadership quality has an outsized effect on team outcomes. Gallup’s research on manager impact, one of its most consistently replicated findings from the State of the Global Workplace research series, attributes roughly 70% of the variance in team engagement to the manager. Gallup’s most recent global data shows that effect compounding: manager engagement itself fell five points in a single year, from 27% to 22% between 2024 and 2025, a steeper drop than among individual contributors, and fewer than half of managers globally report ever having received formal management training.
Common, well-documented leadership gaps:
- Little or no structured coaching or feedback skill-building
- Promotion based on technical performance rather than management ability
- No formal behavioral assessment is conducted before leaders take on direct reports.
- Inconsistent decision-making and communication under pressure
These are measurable skill gaps, not fixed personality traits. That is exactly why they respond to structured development.
Why Generic Leadership Training Falls Short
A single workshop, without measurement or follow-up coaching, has limited ability to produce sustained behavior change. This is consistent with what DDI’s ongoing leadership research shows. Despite widespread investment in leadership training, confidence in leadership bench strength keeps declining, and high-potential individual contributors are increasingly likely to leave. The findings show that departure intentions in that group rose from 13% in 2020 to 21% in 2024. They also found high-potential employees are roughly 3.7 times more likely to leave when their manager doesn’t provide regular growth opportunities.
Training that isn’t tied to measurement, role-specific data, or ongoing coaching tends not to move these numbers.

The I-O Approach to Leadership Development
At Invictus, leadership development follows a structured, evidence-based sequence rather than a single event:
- Assessment: leaders are evaluated using validated tools, which may include behavioral assessments and structured feedback, typically measured against a defined leadership competency model specific to the organization.
- Diagnosis: specific, role-relevant development needs are identified rather than generic “areas of improvement.”
- Development plan: a customized plan with measurable goals and a timeline.
- Coaching: ongoing coaching focused on behavior change, not just knowledge transfer.
- Measurement: progress tracked against defined indicators over time.
- Integration: leadership development tied explicitly to organizational goals rather than treated as a side initiative.
What the Research Says About Leadership and Burnout
DDI’s Global Leadership Forecast 2025 connects leadership quality directly to both retention and leader wellbeing. Leaders who receive regular coaching and clear development support report lower stress and are less likely to consider leaving their roles. This matters for a reason many organizations overlook, as burnout isn’t confined to individual contributors. DDI’s research shows the leadership layer itself is under acute strain, which then cascades to every team that leader manages.
The Financial Case for Leadership Development
Poor leadership shows up in the numbers organizations already track. The engagement-to-profitability link covered in our piece on organizational assessments is, per Gallup’s own research, heavily manager-driven. An undertrained or disengaged leader provides one of the fastest, most direct routes to these bottom-line costs. Both SHRM and Gallup put the cost of replacing an employee at 50%–200% of annual salary. Replacing a manager or leader tends to sit at the higher end of that range given the disruption to the team they managed.
Leadership development, framed this way, is not a soft-skills expense. It’s a lever on the same metrics finance already cares about.
Managing Risk Through Better Leadership
Inconsistent leadership also creates compliance and legal exposure. Inconsistent decision-making in hiring, promotion, and discipline is exactly the pattern that can trigger adverse-impact findings under the EEOC’s Uniform Guidelines (the “four-fifths rule”). Structured, well-documented leadership practices are one of the more direct ways to reduce that exposure, in addition to improving performance.
Invictus Strategy & Solutions has direct experience supporting government contractors on these compliance-adjacent leadership standards, drawing on our standing as a Service-Disabled Veteran-Owned Small Business (SDVOSB).

How Invictus Approaches Leadership Development
The process typically includes:
- Initial leadership assessment and goal-setting
- Multi-rater feedback collected from peers, managers, and direct reports where appropriate
- Behavioral assessment and leadership-style analysis
- A customized development plan with measurable goals
- Executive coaching focused on behavioral change
- Progress tracking over time
- Integration with organizational performance systems
When to Bring in an I-O Leadership Consultant
Consider leadership development support when your organization sees:
- High turnover concentrated under specific managers
- Talented leaders showing signs of burnout or disengagement
- Difficulty promoting from within due to unclear leadership standards
- Growth that has outpaced current leadership capacity
- Succession-planning gaps in critical roles

FAQ
What is the difference between leadership training and leadership development? Leadership training is typically a one-time event focused on specific skills. Leadership development is an ongoing process that includes assessment, coaching, and measured behavior change over time.
How does Industrial Organizational Psychology improve leadership development? I-O Psychology uses validated assessments and behavioral science to identify specific, role-relevant development needs and build customized plans, rather than relying on generic training content.
How long does executive coaching take to show results? Timelines vary by individual and organization; sustained behavior change from coaching engagements is generally measured over a period of months rather than weeks, consistent with how DDI and other leadership-research organizations track development outcomes.
Is executive coaching only for senior leaders? No. Managers at any level who are ready to build coaching, feedback, or decision-making skills can benefit.
How is leadership development measured? TThrough tools such as structured feedback, team performance and retention data, and progress against the specific goals established in the development plan.
What happens if leaders resist coaching?Instead of treating coaching as mandated compliance, skilled coaches secure buy-in by linking development directly to key goals. They focus on outcomes leaders already care about: team performance, reduced stress, and career trajectory.
