Notes of an IT Architect. Eugeny Shtoltc

      * He contacts the Product Owner to obtain a business description of the required service, and on what features he agreed with the customer, business processes.

      * He liaises with the corporate architect to get the conceptual architecture of the functional area of the service and the requirements of the standards that the service falls under.

      * He contacts the platform architect to get the component base.

      * He contacts the server architects with whom he integrates.

      * He contacts with specialists responsible for procurement (if new servers, paid software are used), security, technical support of the service (if new stacks are used), support, legal department (if OpenSource products are used).

      When joining a project, like a manager, it is necessary to familiarize yourself with what is available and identify the stakeholders (stakeholder). Stakeholder – related to the project. He may be interested in success or, conversely, not interested. ITIL4 (IT Infrastructure Library version 4), a collection of recommendations for the use of ITSM (IT Service Management) from 2019 created by more than 150 authors to build IT developing since 1986, defines such basic types as Sponsor, Customer, User, Service Provider and others:

      * User – a person who uses the service. For example, if the system is developed for the accounting department, then the accountants will be the users, although the customer can be the head of this department. Often they will test the product being developed and evaluate it;

      * Customer – make demands and is responsible for the result from its consumption. For example, if the system is being developed for an internal department, then the head of the department orders this system for his employees in the expectation that their work will become more efficient;

      * The sponsor is the resource owner who approves the payment. For our example, it may be a CFO who considered it economically justified to develop this system to increase efficiency for such a volume with such risks in the current situation;

      * Contractor – an interested party responsible for the provision of services. The contractor can be both internal and external. For architecture, they can be a development team, system engineers, individual departments integrating with their various services, and others;
