Many leadership transitions are made more turbulent than necessary because of misconstrued or misaligned expectations. We can’t stress enough how crucial aligning expectations is to getting off to the right start. Making sure everyone agrees on the important issues and priorities is literally the foundation to building the first hundred days pyramid - and your future success.

Let’s face it, no one, regardless of how experienced or talented, is equally adept at every aspect of a job. In any case, as Immelt points out, even if you are above average across the board, no leader has the time to concentrate on every aspect of the job, especially in the earliest days of a new position. Think about where your personal involvement will yield the most leverage and where someone else might do an even better job.

As you involve more and more people in the change process, you may feel as if you’re treading water. This feeling comes from having to introduce and convince each new wave of people as your changes percolate down through the organization. During your first year there will never be a time when your strategic agenda isn’t being criticized, questioned, and debated. Be patient, and remember that the new converts will need the same time that you and others did to get it.

Creating the conditions for a cultural transformation takes all the tools at your disposal. You can’t, for example, command an internally focused culture to magically metamorphose into one that canonizes its customers. You have to nudge, suggest, cajole, and ultimately convince people that the new environment you’re proposing really is the best one for the business and, perhaps more important, for themselves. That takes time - and a good sense of timing.

Some leaders look back on their first hundred days and say, “If I could do it again, I wouldn’t hesitate so long to make those key people changes or that strategic move.” Others were glad they exercised restraint. In most cases the timing are dependent on the situation.

Communication is a central aspect of leadership and indeed all human activity. It has a magnified effect during your first hundred days. Take care to do it well and do it often, which requires active listening, tailoring communication approaches both to your natural strengths and to the situation, and giving and getting direct feedback. It will help support your strategic and cultural agenda; it will also help you avoid many of the most common pitfalls that threaten new leaders as they try to get off to the right start.
