The first 90 days: why capable leaders stall, and how to make the shift deliberately

Every senior appointment starts with a quiet contradiction. You were chosen for what you have done, then asked to succeed by doing something different. The technical judgement that got you the role is the price of entry. It is rarely the thing that decides how the role goes.

I learned this the hard way in my own first executive transition. The credibility was never the problem. What caught me out was everything around it: leading through people instead of doing the work myself, building trust before I needed it, reading the politics, and knowing when to listen and when to act. What I needed was not more technical knowledge. It was a clear-eyed sense of what the seat actually demanded, and the discipline to make that shift early.

Capability is the entry ticket, not the job

Decades of research into why capable executives come undone, most consistently from the Center for Creative Leadership and from Hogan, point at the same short list every time: weak relationships, failure to build a team, and failure to adapt. Almost never a deficit of technical or functional skill. The higher you go, the more the so-called soft skills become the hard ones.

The skills that earned you the seat are the entry ticket. They are not the differentiator any more.

The transition is where those patterns are set, for better or worse, which is why the first 90 days carry so much weight. It is also why moving deliberately in that window costs so little and pays for years.

Role inertia, the quiet failure mode

There is a particular version of this worth naming, because it is the quiet one. Call it role inertia: continuing to lead as the person you were, holding on to the work that made you successful, instead of revaluing what the new seat actually needs. It is subtle precisely because the old work is the work you are good at. The first 90 days is when you either make the shift or quietly fail to. I have written about that pull, and the moment a trusted colleague pointed it out to me, in Breaking through role inertia.

Read your situation before you set the plan

Not every situation demands the same response, and one of the first tests of executive leadership is recognising what you have inherited. If you walk into a live crisis, you cannot afford to spend the first month listening while events outrun you. If you inherit a strong, stable function, acting with unnecessary urgency can do more damage than inaction, and the cost is usually paid in lost trust. Misreading the situation is one of the fastest ways to lose credibility.

A simple way to name what you have walked into, drawn from Michael Watkins' work, is five situations: a start-up you have to stand up, a turnaround in trouble, accelerated growth outrunning its governance, a realignment that is drifting but cannot yet see it, and sustaining success you are trusted to protect. Each rewards a different pace and a different first move. Decide what you have inherited before you decide what to do about it.

Treat trust as the job, not a by-product

Influence, not authority, is what actually moves an organisation. Trust is the currency you spend, and it does two things at once. It sets your speed: where trust is high, decisions move quickly and cost little; where it is low, you pay a tax on every interaction. And it sets your reach: where it is absent, people will not give you honest disagreement, so you get false consensus, then weak commitment, then poor results. New executives tend to over-invest in proving competence, the part that got them the role, and under-invest in signalling intent. Make your intent visible early. People forgive a capability gap far sooner than a motive they cannot read.

Name your own derailer

Capable executives fail on a small number of predictable patterns, and almost always on the one they cannot see in themselves. The point is not to score yourself well. It is to name the one most likely to be yours while there is still time to manage it: being right and abrasive, holding too much yourself, running your last role's playbook in a system that is not your last system, activity without outcomes, or going quiet on the unglamorous risks like cyber and governance until they fail loudly.

You do not need more concepts. You need a cadence, and the discipline to hold it. Listen and diagnose first, then decide and align, then deliver visible value and set your operating rhythm. What makes it work is not the calendar. It is doing the harder, quieter work, the trust, the situation read, the honest look at your own derailers, deliberately rather than by accident.
