Application Service Providing (ASP)
Based on ASP, companies can outsource entire administrative departments or process steps. The application service provider is responsible for the operation and maintenance of the service. The outsourcing company does not purchase the required software, but rents it via the data network to use it as needed.
Business Process Outsourcing (BPO)
This is a special form of outsourcing and describes the outsourcing of entire business processes. The difference from other forms of outsourcing is that not a part of the structure organisation (i.e. an organisational unit/department), but a part of the process organisation is to be outsourced.
Business Transformation Outsourcing (BTO)
This service model combines counseling and operation of IT and business processes, i.e. it integrates outsourcing and business consulting.
Comprehensive Outsourcing/Complete Outsourcing
This outsourcing model is used to outsource entire company departments, including major parts of the personnel, to a third-party company.
Managed Services
For a defined period of time, services are rendered by a specialised supplier. The client may then make use of, but also cancel, the service at any time.
Outtasking
External service providers take over specific tasks. The difference from BPO is that the outsourcing company keeps process control.
Transitional Outsourcing
This model helps companies cope with technology changes: The company transfers the relevant tasks to a third-party provider who is skilled in both the existing and the new technology.
