In a recent LinkedIn post, Tim Denning shares a personal anecdote about a significant error early in his career and the valuable lesson it taught him about organizational culture and professional growth. Denning highlights how a pricing mistake with a major Silicon Valley tech client could have led to his termination, but instead, became a turning point due to his manager’s supportive approach.

The High Stakes of a Pricing Error

Denning recounts a critical situation from five years prior where an incorrect rate was sent to a key client, resulting in a loss for his company with every transaction. He admits to feeling immense pressure and the fear of being let go, especially as a relatively new member of the team.

“I felt terrible. I was still regarded as a recent addition to the group. I readied myself to be terminated.”

The initial shock, however, wasn’t the error itself, but the subsequent conversation with his team manager. This interaction, as Denning describes, shifted the focus from the mistake to the resolution.

From Error to Opportunity: The Manager’s Role

Denning emphasizes the critical role of leadership in how mistakes are handled within an organization. His manager’s response was not one of blame, but of guidance and problem-solving.

“It’s not the error you created. It’s how you fix it. That’s what matters.”

This perspective empowered Denning to proactively address the issue with the client. He openly communicated the mistake and the circumstances surrounding it, requesting an opportunity to rectify the situation. This transparency, Denning suggests, was met with understanding from the client, who recognized the impracticality of the incorrectly quoted rates.

Taking Ownership and Implementing Solutions

Following the client’s agreement to the corrected rates, Denning details the collaborative effort with his manager to prevent future occurrences. They implemented a double-verification system for all estimates, a practical measure to enhance accuracy and operational integrity.

“Poor companies will terminate you for making errors. Great companies will collaborate with you to transform the error into a success and enhance systems simultaneously.”

Denning argues that the distinction between poor and great companies lies in their approach to employee errors. While some organizations might resort to immediate termination, he posits that more effective companies see mistakes as opportunities for improvement and employee development. This philosophy fosters a culture of learning and resilience.

Choosing the Right Environment

The core message from Denning’s post is a call for professionals to evaluate their work environments based on how they handle errors. He concludes with a simple yet profound piece of advice:

“Choose carefully.”

This seemingly brief statement encapsulates the importance of seeking out workplaces that support growth, encourage transparency, and view challenges, including mistakes, as catalysts for positive change and system enhancement. Denning’s experience underscores that accountability, coupled with supportive leadership, can turn a potential career-ending event into a valuable learning experience and a demonstration of competence.
