Successful application services are based on a total of four pillars that must be fulfilled. This ensures that both employees in day-to-day operations and the company itself benefit from them. First of all, there is communication. Clear, secure and, above all, timely communication at eye level is important in order to clearly communicate goals and threats and to clearly identify the need for action. Quality is another pillar in management. As a manager, the quality of one's own work and thus also the quality of the applications must always be the focus. This automatically leads to the pillar of speed. This includes not only the speed of response when problems arise, but also the speed of the applications themselves. Waiting times for users slow down the entire workflow in the company. The last pillar concerns costs. Good cost awareness and a sustainable cost-benefit calculation are important in order to maintain a balance in this system.
