1) Development for to-be managers is needed. Skills in planning, delegation and evaluation are new competencies needed by those who are suddenly working as new managers. They have to be trained and taught or mentored. The possible cost of training is worth it.
2) Organizations should send their managers to schools – there are plenty of executive education programs. Courses in the basics of administrative can also prove useful, be it accounting, database management or ethics and business law.
3) Mentoring programs can be a huge help for new managers. Successful organizations know this. The mentor does not have to be a senior leader. Someone from another department, who is one or two levels above the new manager, is OK. Managers should spend some time together with their peers in order to talk about practical managerial topics about people and various systems.
