What both parties need to understand is that their relationship with one with the other will have changed dramatically with the introduction of such a transitional service agreement. Therefore, security and data protection should be treated in the same way as in an outsourcing relationship and, in such cases, many countries with data protection legislation need consent for the transfer of personal data to third parties. Transition service agreements can be very difficult to manage if they are not properly defined. An agreement to provide such a service is common when the buyer does not have the system or management capabilities to absorb the acquisition itself, but not the seller. This situation can occur when a large company sells an industry to a less infrastructure-intensive buyer, for example.B. a new company that has not had time to develop such skills. A transition service agreement (TSA) is an agreement between a buyer and a seller in which the seller enters into its services and know-how with the buyer for a certain period of time in order to support the buyer and get used to its newly acquired assets, infrastructure, systems, etc. An ASD is a fairly accurate business example of real events: Mom and Dad help spend their son for the first few months he works, but soon enough he will be able to take care of everything himself.
