The current world of VUK requires vertical development. One of the main advantages of vertical development is that it increases mental complexity, innovation, emotional intelligence and the ability to constructively resolve conflicts. The result is an improved ability to interpret situations and make effective decisions, which are the main areas of competence for solving problems in the WUCA world. Vertical development helps make individual changes more demanding, mature and competent. In order to cope with the complexity of the VUK world, you need a bigger glass of water. What exactly does it mean? Acquiring skills, qualifications and experience is essentially a process of learning or horizontal development. In other words, horizontal development transforms what is known; vertical development transforms the way of thinking. But 2020 will be remembered as the year when all organizations had to deal with the world of VUKA. But even before VOCID, PwC’s annual CEO survey showed that most CEOs said they had no talent to grow their business and respond to growing complexity. Vertical development means changing their minds. The more project managers develop in their leadership role, the less attention is paid to mastering their people, methods, tools and techniques, and the more they learn. Voices on Project Management offers ideas, advice, recommendations and personal stories from project managers from different regions and industries.
