This document was prepared to demonstrate the value of Enterprise Architecture solutions in constantly progressing organizations. Dealing with certain number of applications, functions, data warehouses, technical and business requirements, it is always challenging to build company processes and the surrounding architecture in the most effective way possible.

The document examines an existing company by analyzing available information based on management interviews and provided documents (application portfolio, functional descriptions, organizational hierarchy, and ticket statistics). IT architecture and business processes are measured and evaluated, selecting the business critical elements for optimization. Business processes are mapped to applications. Requirements and needs are described.

Commonly known frameworks and best practices were used for model building and optimization. These methodologies for Enterprise Architecture (TOGAF), service management (ITIL), and in some cases project management (PMI). Business process management tool (MEGA software) was used to discover hidden relations within the architecture, and to find optimization elements comparing the old solution to a possible new setup.

In this document examines the company’s maturity and suggests optimizations. These suggestions take into consideration the performed analysis which was done from the internal IT operations ticketing system. Issue database was built by development using SQL queries for database extraction and Visual Basic scripts for data cleaning. Analytical results are visualized and could be used in management reports.

Risk assessment was performed for business critical applications using a formula developed to operate on statistical data from the ticketing database. The assessment supports regular review of application availability and reliability to ensure business continuity.
