Powerpoint

We need to make a powerpoint to visualize a diagram that shows the difference between two setups. 1. setup is an old type setup with a lot of communication between different partners. This communication will lead to a service and a manual invoice. In case the "operator" updates their specifications along the way, the communication will go back and forth again, before a manual invoice can be created. 2. setup is a new way, were a lot of the communication is skipped due to a system, that generates an automatic estimated cost. This is updated a long the way as the "operator" makes changes. At the end it will generate an automatic invoice that eqauls the actual service received.
