What Are The Four Models And Frameworks For Delivering ITM?

In order to obtain solutions for IT service management, we need to understand the main concepts of delivering IT services and how they are related. This article designs a model, using which an organisation can understand about how they are delivered by internal and external providers. This model is applicable for in-house organisations and IT service providers. There are too many models and frameworks for ITSM, which causes confusion for anyone leading a service-provisioning organisation; hence, integrating all these models and frameworks is very important, and requires common approaches for arriving at solutions.
This research paper offers the ITSM managers a model that covers the entire ITSM space. The main part of the model is that it encompasses

The financial entity appears only in the service provision domain because costs and prices can be calculated only at the SD level.
The Organisation domain consists of six entities:
Organisation- relationship between the units accountable for delivering service; location- place where the people and machines are located; location type- type or class of location; the other entities are role and skills. Roles rely on skills.
The process domain includes three basic concepts:
Process reference model- set of processes required for ITSM to provide a breakdown of activities; process flow models- processes further by breaking the activities into tasks, which are linked by activity flows; service flows- processes to be implemented in practice.
The tools and technology domain comes after all the above mentioned domains, to achieve appropriate level of automation. The entities of this domain are as follows:
Use case model- role of the users of the services; technical component model- functional specification of the system; Operational mode- delivery of services through specific technologies;
Data and information model consists of the
