One hundred years ago today the Titanic sunk in the icy waters of the North Atlantic in a disaster that claimed the lives of 1,514 passengers.

A passing collision with an iceberg caused the ship to take on water and ultimately sink, which could have been prevented—or at least mitigated—if the Titanic’s leaders had acted differently, according to a new e-book.

“The captain and officers put their faith in the supposedly unsinkable ship, with all its modern technology, and ignored some basic leadership tenets that might have prevented the disaster or at least made the outcome less terrible,” explained the author Jocelyn R. Davis in a blog post on Forum.com.

Davis is head of global research and development at leadership development company Forum, and her e-book on the Titanic is “Leadership Failures Sink Unsinkable Ship: Business Lessons from the Titanic.”

“Today, the same thing can happen in businesses,” she added on the blog. “Leaders often overlook people factors and fall into one of the following traps.”
