Extreme project management (XPM) refers to a method of managing very complex and very uncertain projects. Extreme project management differs from traditional project management mainly in its open, elastic and nondeterministic approach. The main focus of XPM is on the human side of project management (e.g. managing project stakeholders), rather than on intricate scheduling techniques and heavy formalism. Extreme project management corresponds to extreme programming. Advanced approaches to extreme project management utilize the principles of human interaction management to deal with the complexities of human collaboration. The term "Extreme project management" has not been picked up by any of the international organizations developing Project Management Standards. What might be understood as a similar concept is "Agile Project Management". The ISO Standard ISO 21502:2020 refers to the term "agile" as a delivery approach (of products; related to project scope), and the PMBoK Standard published by the Project Management Institute refers to an "adaptive" type of development lifecycle also called "agile" or "change-driven" with regard to the product development lifecycle of a project (an element of the project lifecycle). As it is known, the software industry is a fast growing domain and in constant development and change. Despite the fact that there are plenty of methodologies and techniques used when it comes to project management, some new, and others that have been used for decades, extreme project management is one of the modern approaches to project management in this industry. Given that requirements are constantly changing and technology is evolving very rapidly, extreme projects move forward very fast and allow for teams to work in shorter timelines, being able to better understand and approve each other's ideas and work. For extreme project management to produce rapid change, it is necessary for all team members to communicate and reach full understanding.
