A project is a business for a certain period of time. It has its own project organization consisting of different rules, roles, experience levels and communication structures. Due to complex project tasks as well as budget and time restrictions, the organization must not be neglected under any circumstances and must ensure a clear definition of tasks and responsibilities as well as a clear demarcation from the line organization. This is the only way to ensure cost- and time-efficient project progress. There are many different approaches to setting up the project organization and implementing the project – but what is inevitable is the use of employees across different levels of experience. This allows the distribution of tasks and responsibilities to employees with the appropriate level of experience. This makes the processing of tasks more effective and efficient in terms of time and costs. This article shows the different levels of experience that project management and consulting offer in the course of a career and the exciting tasks and responsibilities that are associated with them in the context of project work.
