The first 90 days after an executive promotion

Michael Watkins’s 2003 book, The First 90 Days, popularized ninety days as the frame for a leadership transition. Most of those days go to introductions, listening tours and early wins, and none of these tests whether the executive and the role fit.

G. Damon Wells

Find what changed in the job

Start by mapping the differences between the old role and the new one. Feedback slows down, sometimes from weeks to a quarter. Decisions that used to stay inside the executive’s own team now depend on peers who report to someone else. Information arrives after several people have edited it. A mistake can travel a long way before anyone can repair it.

Each difference marks a place where an old strength may reverse. Direct control can turn into interference, and speed into volatility.

Run a few bounded tests

Pick two or three behaviors tied to the friction the map predicts. Give each one an owner, a signal to watch and a review date. Delegating two recurring operating decisions is one example. Reviewing dissent before each major decision is another, and so is changing how often weak signals are brought to the executive.

At day 90, put the results next to the original map. Some tests will have worked, and some will show that the map was wrong. Both are worth having. The 90-day plan in the P×E Development Platform works the same way. Each priority comes with a stated limitation, the signal that would show it is wrong, and conditions for keeping, revising or stopping it.

  1. Weeks 1–3Map the changeCompare the old role and the new one, and write down which habits are likely to cost.
  2. Weeks 4–11Run two or three testsEach has an owner, a signal to watch and a review date.
  3. Day 90Compare with the mapKeep, revise or stop each test, and correct the map itself.

Protect the path for bad news

Frances Milliken, Elizabeth Morrison and Patricia Hewlin published interviews with 40 employees in 2003 about issues they had not raised with their bosses. Most had been concerned about something at work and kept it from a supervisor. The reason they gave most often was fear of being seen or labeled negatively, and of damaging relationships they valued.

An executive stands at the end of a long chain of those decisions. By the time a concern arrives, several people have judged whether it was safe, important and presentable enough to pass on. So the executive can feel well informed and still hear only what the system has learned to deliver. In the first months, find out where weak signals start and who edits them. Then watch how you respond to the first piece of bad news, because the people below are watching too.

  1. Front line
  2. Supervisor
  3. Manager
  4. Director
  5. Executive

At each step someone decides what is safe, important and presentable enough to pass on.

Clarify decision rights before demanding speed

Transition plans often reward visible action before anyone has settled who owns which decisions. Teams wait. Peers negotiate around the new executive. Routine questions travel upward, because no one knows whether the new leader wants to be consulted or asked for permission.

Write down a small set of recurring decisions. For each, list the owner, the input it needs, the conditions that bring it to the executive, and the date it will be reviewed.

Review the arena, not only the executive

At day 90 most organizations ask whether the executive adapted. They should also ask whether the role was described accurately. An operation sold as stable may depend on things the briefing left out. A high-threat assignment may come without the authority or resources to control its risks. Right Leader, Wrong Arena says a Chaotic arena gives a leader “something like ninety days to change the structure or watch it fail.” That puts an accurate description of the arena inside the executive’s first quarter.

The executive answers for their choices. The organization answers for the conditions it created, the authority it granted and the information it let travel.
