Bali Padda is the operations maverick behind LEGO's remarkable turnaround from a business basket-case, struggling to deliver on its orders, to the biggest and most profitable toy brand in the world.

As Chief Operations Officer at LEGO, Bali overhauled the toy company by shaking up its operations and instilling essential business fundamentals. He resolved issues across the supply chain and forged close partnerships between functions. He cut unpopular product lines and diverted the company's attention on hero items. He developed a relentless focus on customer service—of delivering what was promised—and he instituted weekly performance briefings known as the Visual Factory, which ultimately spread throughout the whole organization and transformed culture and performance. LEGO became the largest toy manufacturer in the world, and Bali was honoured with becoming the company's first non-Danish CEO in 2017.

In Deliver What You Promise, Bali distils his methodology at LEGO into ten essential, fundamental lessons. From how to reduce complexity to prizing reliability over agility. Why a business should be treated like a living organism and how to bring everyone together under a shared sense of purpose. On when to use soft and hard managerial skills and the hidden risks of success.

Illustrated by insider stories from LEGO, these are enduring principles that both young starters and established leaders alike need to know and can implement straight away, to deliver on what is promised.
