Those are not four versions of the same job. They should not receive four versions of the same leadership program.
A first-time supervisor learning to lead other people is doing fundamentally different work from an executive responsible for the whole organization. Between those two points, leadership changes again.
The leader moves from doing the work to leading people. From leading people to getting results through other leaders. From functional expertise to broader organizational responsibility. And eventually, from leading part of the organization to thinking for the whole.
The first move into formal leadership changes how success happens. Results can no longer come primarily from personal expertise and effort. They increasingly come through other people.
The work changes again when the people being led are leaders themselves. The challenge becomes creating clarity, accountability, and consistency without stepping back into their jobs.
Expertise may have built the career. At this level it can no longer define the boundaries of the leadership. Success increasingly depends on seeing across functions, balancing competing priorities, and leading beyond what the leader personally knows best.
At the enterprise level, decisions cross boundaries. Leaders must weigh consequences they cannot fully predict, balance competing interests, and make choices for the health of the institution , not simply the function they came from.
Your organization may have new supervisors learning to lead people while experienced managers are learning to lead other leaders and senior executives are taking on broader responsibility. That is normal.
The useful question is not which transition matters most. It is where responsibility is changing, and what those leaders need now.
Where is responsibility changing in the next twelve months, and who is moving into it?
A leadership transition happens when a change in responsibility changes the work of leadership itself. The leader may have a new title, but the important change is what they are now responsible for, how results must be achieved, which decisions become theirs, and what others need from them.
BlackRidge maps four. SHIFT is the move from doing the work to leading others. ARENA is the move from leading people to leading through other leaders. ASCENT is the move from functional expertise to broader organizational leadership. EDGE is the move from leading part of the organization to thinking for the whole. Each transition creates different developmental demands.
Because the work is not the same. A new supervisor may need to stop solving every problem personally. A manager of managers must learn to lead without taking over. A senior functional leader has to see beyond their expertise. An enterprise leader must make decisions for the whole organization. Development becomes more useful when it reflects those differences.
Start with responsibility, not title. Ask what the person is becoming responsible for, how they must now create results, which decisions have become theirs, and who depends on their leadership. BlackRidge frames that transition before development begins.
