Once you determine an individual's leadership readiness, giving them opportunities to expand their leadership ability is essential. Rothwell (2010) suggested some powerful leadership development experiences: 

Supporting People: Experiences that provide opportunities to lead, supervise, coach, or mentor people for whom one is either directly or indirectly responsible. 

Managing Profit and Loss: Experiences that provide opportunities to lead or manage an operation, major project, or business with end-to-end responsibility for performance. 

Developing New Directions: Experiences that provide opportunities to start something new, make strategic changes, carry out a reorganization 

Serving Customers: Experiences that provide opportunities to interact directly with external customers. 

It is leveraging Technology: Experiences that provide opportunities to transform technological capacity into profitable products and services. 

Managing Business Diversity: Experiences that provide opportunities to have sole responsibility for a job large in scope with multiple functions 

Working Internationally: Experiences that provide opportunities to develop global business understanding and cultural awareness. 

Inheriting Problems: Experiences that provide opportunities to fix problems created by former incumbents 

Having High Stakes: Experiences where high visibility and responsibility for success or failure is evident 

Experiencing Job Overload: Experiences where the sheer size of the job requires a significant investment of time and energy 

Proving Oneself: Experiences where one has to demonstrate one's ability to handle the job. 

In your opinion, which of the points above should a selecting official consider most in promoting someone to a leadership position and why?
