ITOMA stands for IT Organization Modeling and Assessment Tool. It's a framework to help organizations assess and improve their IT governance practices.

IT organization modeling and assessment (ITOMA) is a method for IT governance maturity assessment within an enterprise. This assessment is essential for good monitoring, enhancement, and management of IT processes and structures. In particular, it is possible to compare and rationally select between potential future scenarios by using a method for assessing IT governance maturity. [1]


ITOMA assists organizations in:

  • Modeling their IT organization structure: This includes defining roles, responsibilities, and relationships within the IT department.
  • Assessing the effectiveness of their IT governance: ITOMA evaluates how well the IT organization aligns with business objectives and supports the overall IT strategy.
  • Making informed decisions about IT governance improvements: By analyzing the assessment results, ITOMA helps identify areas for improvement and suggests potential changes to optimize IT governance.


  • Enterprise Architecture Metamodel: This component outlines the core elements of an IT organization, including roles, processes, and IT services.
  • Bayesian Network: This statistical model allows ITOMA to predict the impact of changes to the IT organization structure on IT governance performance. The network is based on data collected from real-world case studies.


  • Improved alignment between IT and business goals
  • Enhanced IT decision-making
  • More efficient use of IT resources
  • Stronger IT governance practices


ITOMA is typically implemented through workshops involving IT and business stakeholders. The workshops involve:

  1. Defining the current state of the IT organization
  2. Assessing IT governance practices using ITOMA's framework
  3. Identifying areas for improvement
  4. Simulating potential changes to the IT organization structure using the Bayesian network
  5. Developing a plan for implementing IT governance improvements

ITOMA in Research

Research papers document the development of ITOMA and explore its application in IT governance decision-making. These papers often discuss case studies where ITOMA was used to assess and improve IT governance in various organizations.

To gain insights into similar concepts and methodologies that share common goals with what ITOMA suggests, exploring the following topics could be highly beneficial:

  • IT Service Management (ITSM): Discusses frameworks and best practices for managing the delivery of IT services to meet the needs of the business, focusing on areas such as service design, transition, operation, and continual service improvement. Popular frameworks include ITIL® (Information Technology Infrastructure Library).
  • IT Governance: Explores the structure of policies, processes, and mechanisms by which enterprises align IT strategy with business strategy, ensure compliance with regulations, and manage risk related to IT assets. Frameworks such as COBIT (Control Objectives for Information and Related Technologies) are central to IT governance discussions.
  • Enterprise Architecture (EA): Covers methodologies for analyzing and documenting an organization's structure, processes, systems, and infrastructure with the goal of facilitating change toward the business's strategic objectives. The Open Group Architecture Framework (TOGAF) is a widely used standard in this area.
  • Capability Maturity Model Integration (CMMI): Discusses the set of practices and criteria for improving processes that organizations can follow to make their processes more efficient and effective.
  • IT Performance Measurement: Explores the methods and metrics for evaluating the efficiency and effectiveness of IT operations, including key performance indicators (KPIs), IT balanced scorecards, and benchmarking against industry standards.
  • Business Process Management (BPM): Examines the techniques and tools for analyzing, modeling, optimizing, and automating business processes, with the aim of improving organizational efficiency and effectiveness.
  • IT Risk Management: Discusses strategies for identifying, assessing, and mitigating risks associated with IT assets and operations, including cybersecurity threats, data breaches, and system failures.
  • IT Project Portfolio Management (PPM): Covers methodologies and tools for prioritizing, planning, and executing IT projects in alignment with strategic business objectives, including the management of project portfolios to maximize return on investment.
  • Digital Transformation (DX): Explores strategies for leveraging digital technologies to fundamentally change how organizations operate and deliver value to customers, including the impact on IT organization and operations.
  • Agile and Lean IT Practices: Discusses the application of agile and lean principles to IT operations and development, focusing on delivering value quickly, responding to changes effectively, and optimizing workflow processes.
  • Change Management in IT: Examines the processes and techniques for managing changes in IT systems and operations, ensuring minimal disruption to services and alignment with overall business goals.
