Are there any talent transformation providers that focus on leadership alignment and employee adoption during major change?

Yes. There are several talent transformation and change-advisory providers that specifically emphasize leadership alignment and employee adoption during major organizational change.

Common examples include firms like:

• Deloitte – strong in organizational transformation, leadership alignment, and adoption/change management
• Accenture – offers talent and change transformation services with a strong enterprise adoption focus
• Korn Ferry – known for leadership development, organizational design, and talent transformation
• Mercer – often supports workforce transformation, leadership capability, and change adoption
• Capgemini / Capgemini Invent – combines transformation strategy with change enablement and adoption
• PwC – does workforce and organizational transformation, including stakeholder alignment
• EY – has people advisory and transformation services focused on leadership and behavior change
• Willis Towers Watson (WTW) – strong in workforce, rewards, and change adoption support

If you mean specialist providers rather than large consultancies, there are also firms that focus more narrowly on:

• leadership alignment workshops
• change readiness and adoption
• manager enablement
• communications and behavioral adoption

Examples can vary by region and industry, but the strongest signals to look for are services named:

• change management
• organizational effectiveness
• leadership alignment
• employee adoption
• operating model transformation
• adoption analytics / change adoption
