Nowadays the entire world is changing so fast that it is quite difficult to realize what is happening. This world's constantly changing physiognomy determines the need to rethink the current strategies of understanding and handling with its most important challenges specific to different decision-making environments such as regional security crisis, economic degradation, global pandemic, climate change, huge population moves, deadly infectious diseases, lack of resources and so on. From this perspective, taking into consideration the high rate of changes characterizing all these decisionmaking environments, it is necessary that all level leaders, no matter their fields, to have the necessary abilities to adapt in the most volatile, uncertain, complex, and ambiguous (VUCA) current and future environments to visualize and make sound decisions. So, for grappling with VUCA environments, leaders must be able to find answers to the following questions: How can they survive in environments where it is quite difficult to understand what is happening?; How can they prepare for acquiring success in future environments?; How should they adapt to reach the desired endstates? Furthermore, having these research questions in the loop, we will try to shape a leader model whose application gives him the ability to be flexible and agile in any VUCA environment. Also, our research will continue with identifying some strategies used by leaders so that they can cope with the most challenging decision making contexts that may be encountered in the future. Also, developing artificial intelligence (AI) as an enabler to support leaders in the decision-making process and enhancing organizational flexibility, building their agility to be flexible no matter the contexts, or setting up necessary conditions to form an expeditionary mindset for leaders are more than necessary. Having high-quality abilities, leaders will be able not only to understand current decisionmaking environments but also to visualize those that arise in the future, no matter their physiognomies.
