Structure, Governance, Ethics
1. How is the IT department organized?
IT systems services: The department of people who provide technical support for
IT services such as email systems, accounting applications, desktop computers,
and mobile devices which are used in most organizations.
- Organizational structure varies: depending on the organization’s size, culture,
competitive environment, industry, and other factors. Larger organizations with
independent departments will have a group of senior executives. Smaller
companies may combine some of these departments.
- Technology office: investigates new information systems technologies and
determines how the organization can benefit from them. For example, many
organizations are using web services technology and planning how they can best
use that technology to accomplish their goals and objectives.
- C hief technology officer (CTO): sorts through new ideas and products to identify
those that are most relevant to the organization. The CTO’s job requires deep
knowledge of information technology and the ability to envision how new IT will
affect the organization over time.
- Websites: Traditionally designed and maintained by the IT department, but now this task
belongs to the marketing department in order to keep up with branding and control of content;
while IT provides technical support for the website. Project managers. Lead analysts, developers
and technical analysts are on the web development team.
2. What is information technology architecture?
-IT architecture: basic, but complex framework for all the computers, systems,
and information management that support organizational services. Its complexity
increases as more services are supported and different technologies are used. A
popular metamodel to organize the IT architecture is Zachman’s framework.
-Enterprise architect: person who manages the IT architecture. He/she creates a
blueprint of an organization’s information systems and the management of these
systems; while developing the blueprint, the architect considers organizational
objectives, business processes, databases, information flows, operating systems,
applications and software and supporting technology.
3. What is alignment, why is it important and why is it difficult?
Alignment: ongoing process of matching organizational objectives with IT architecture. Fitting
IT architecture to business objectives is continuous challenge. It is measured as the degree to
which the IT department’s missions, objectives, and plans overlapped with the overall business
missions, objectives, and plans. Communication between business and IT executives is the most
important indicator of alignment.
It is difficult to achieve because it depends on organizational context, business goals & IT
architecture in the organization.
4. What is information systems governance?

processes for IT & related services. The goal of IS governance is to improve the benefits of an
organization’s IT investment over time by:
