Abstract  Purpose: The purpose of the degree project is to examine how the development within the planning process has been over the past thirty years and also to highlight challenges and the shortcomings that arose in the last 30 years. Through streamlining, minimizing costs and specifying the design leads to further development and simplicity in the planning process. Method: The method in the degree project began with a literature study where a theoretical frame of reference regarding the planning process is presented to expand the knowledge of the subject. Subsequently, a qualitative study was conducted in the form of interviews with experienced individuals in the construction industry. With the literature studies and interviews as a basis, practical application was also carried out in the form of a model study where the functionality of different software was considered. Results: The results of the study present a summation of the interviews conducted. Digital development has facilitated with calculation programs or drawings that are simpler than before, and easier to edit with the help of digitization, but it has also resulted in poor communication, poorer connection and less collaboration because of this digital development. Furthermore, these problems have led to several errors in the projects. Another important problem that is noticed in the work is to cut off the projects in smaller moments that always create confusion and shortcomings. The stage shifts in the projects damage two major factors which are time and cost. After a summer of the interviews conducted, the data collected from the literature study were analyzed and linked. The analysis led to a proposal for improvement which is presented in the results of the work. Conclusions: Regarding the results of the study conducted in this degree project, plenty of conclusions are drawn on how the planning process have developed over the past 30 years, such as where in the planning process there are shortcomings, what development opportunities there are and what their potential consequences are.
