Selected Media Reviews

Inc. Best Books for Business Owners 2010: “Jonathan Byrnes…makes the shrewd observation that no one in companies actually manages profitability. As a result, opportunities go unexplored and inefficiencies are allowed to linger. Worse, the mindless pursuit of new business means companies bring on customers who actually end up costing them. This enormously practical book shows readers how to rethink every part of their companies – from sales to supply chains to service – with an eye toward sweeping up money currently left on the table.”

— Leigh Buchanan, Dec. 8, 2010

“Sure, the global recession took a big bite out of earnings at plenty of companies, but according to profitability guru and MIT senior lecturer Jonathan L.S. Byrnes, the downturn has masked an even deeper problem: Most businesses are still operating the way they did in the Age of Mass Markets….He explains how to thrive in what he calls the Age of Precision Markets, an era ushered in by internet-empowered consumers and fraught with changes ‘as profound and disruptive as those that occurred when roads were first paved.’…No question about it, the changes Byrnes recommends in Islands of Profit add up to a total overhaul of practices and assumptions that have lingered unexamined in some companies for decades, which is why he also throws in some shrewd advice about handling resistance to change.”

— Anne Fisher
CNNMoney/Fortune, Nov. 12, 2010

“In the corporate world, MIT’s Jonathan Byrnes is the go-to man for one reason: he can figure out where the profit is and where it isn’t. Byrnes, a consultant and senior lecturer at MIT has authored more than one hundred books, articles, cases, notes, and expert submissions. For four years he wrote “The Bottom Line,” a highly-regarded Harvard Business School monthly column on managing profitability. In short – he knows what he’s talking about.”

— Gloria McDonough-Taub, Oct. 22, 2010

“Islands delivers an executive ed program’s worth of insight. Most CEOs know that some kinds of revenue are more profitable than others. Byrnes explains in great detail how to turn that knowledge into action.”

— Leigh Buchanan, Oct. 1, 2010

“An island destination you can’t miss…Top executives and managers at all levels and in any kind of enterprise should not miss a single word of a business book that deserves wide recognition for addressing the key to survival: making a profit.”

— Soundview BizBook Review of the Week
Feb. 14, 2011

“No business leader can afford to ignore the urgent and sobering recommendations Dr. Jonathan Byrnes offers in his new book ‘Islands of Profit in a Sea of Red Ink.’ Given the shocking prevalence of unprofitable business activity in an exceptionally turbulent marketplace, the advice he offers in ‘Islands of Profit’ can help ensure the profitability, stability, and growth of companies at every level.”
