Book excerpt: The essential guide for project managers and leaders.Project managers are often responsible for big teams and millions (sometimes billions) of dollars to deliver successful outcomes on time and within budget. But the reality is, most complex projects don't live up to their promise - they often fail, under-deliver or get delivered but burn out everyone in the process. Author and experienced project manager, Kieran Duck, argues that this is because the normal approach to project management doesn't work when projects are complex. The traditional emphasis on certainty and predictability comes from an industrial era where the focus was on controlling resources and effort. These days projects are unpredictable, they are emergent and performance relies on the opinions of key stakeholders and team members.The Complex Project Toolkit provides a way through this. Based on the concepts of design thinking, this comprehensive toolkit adds to existing project management approaches with new mindsets, practices and skills that will lift the performance of your most ambitious projects and improve the experience for everyone involved.
