Flowcharts and diagrams are becoming increasingly important as the complexity of the IT environment grows. For example, it works very well to visually represent this type of environment by means of an ICT architecture plate. This helps reduce complexity and increase stability and scalability. But you can also design flowcharts for example customer service processes. There are many tools available with which you can do this (often for free). Here you will find a selection of these types of applications.
