Most businesses regardless of size will promote personnel without providing training to their personnel in their new position. Each position from supervisor to CEO requires different skills at each level and without training the newly promoted employee can perform underperform. The impact can be felt in increased employee turnover, decreased productivity, to at its extreme, a toxic environment. Leadership development is a necessary component of a well-run company and can increase productivity and employee retention. Leadership development programs usually have three components for success. They are employee assessment, training in the form of a course or program, and follow-up after the initial course to ensure that deliverables are accomplished.
