BOARDROOM LESSONS

Mistakes I Made as a CFO - So You Don't Have To

Most business books focus on success.
This one focuses on mistakes - because that's where the real lessons live.

After more than four decades as a CFO and senior finance leader, David Jolliffe learned that the most costly problems in business rarely begin as disasters. They begin as small decisions, overlooked details, or assumptions that quietly go unchallenged.

In Boardroom Lessons, he shares the real experiences that shaped his career - from early misjudgements and financial control failures to strategic decisions, leadership pressures, and high-stakes boardroom challenges. These are not theoretical case studies. They are real situations drawn from decades of working inside complex organizations, private equity-backed businesses, and international operations.

Each chapter tells the story of a mistake, explains what went wrong, and highlights the lesson that emerged from it. Some lessons are technical. Many are human. All are practical.

This book offers an honest look at how decisions are made under pressure, how problems develop over time, and how leadership judgement determines whether businesses succeed or fail.

• Why small financial mistakes can create major business risks
• How weak controls quietly grow into serious problems
• When instinct matters more than spreadsheets
• Why strong systems protect businesses from hidden threats
• How strategy decisions can succeed - or fail - based on execution
• The leadership habits that separate strong organizations from weak ones
• How to recognize warning signs before they become crises

Boardroom Lessons is written for:

• Finance professionals and accountants
• Business leaders and senior managers
• Entrepreneurs and founders
• Board members and investors
• Young professionals building careers in business
• Anyone responsible for making decisions that carry real consequences

Whether you are early in your career or already leading teams, the lessons in this book provide practical insight into how businesses really operate - beyond spreadsheets, forecasts, and strategy presentations.

In business, experience is often a hard and expensive teacher.

Learning from your own mistakes can take years.
Learning from someone else's mistakes takes minutes.

Boardroom Lessons offers decades of hard-earned insight - so you don't have to learn everything the hard way.
