Glowing Partners 05 March 2026

Michael Watkins' classic work "The First 90 Days" is one of the most widely read books in management literature. Because research shows that 40% of new leaders fail within 18 months of taking on their role. This rate is both surprising and preventable.

The Biggest Mistakes in the First 90 Days

Pressure to take quick action: Many new leaders make decisions too quickly to show they are "doing something." This haste often means making changes without understanding the context.

Not listening: With the "ready solution" feeling from previous experiences, they start talking instead of listening to the organization and people.

Ignoring team dynamics: While focusing on technical success factors, relationships, trust, and culture are neglected.
