Architect Roles
 1st and in advance, what are IT architect types:
 Software Architect
Design the technical solution of the entire application. The logical and
physical structure.
 Infrastructure Architect
Ensure the safe and productive deployment and operation of enterprise
applications. This involves managing hardware, network and operating
systems.
 Enterprise Architect
Ensure convergence between business needs and technologies by
establishing architectural guidelines such as enterprise conceptual data
models or, in service-oriented environments, business service interfaces.

Who is?
Simply
 Architecture is the structure of the system, comprised of:
 components or building blocks
 the externally visible properties of those components, and
 the relationships among them
 The people who do this are called architects.

Architect Roles
 2nd what’re main skill set in
Architect
 The architect is a technical
leader
 The architect understands
the software development
process
 The architect has knowledge
of the business domain
 The architect has technology
knowledge
 The architect has design skills
 The architect has
programming skills
 The architect is a good
communicator
 The architect makes decisions
 The architect is a negotiator

 Crafting the right architecture to solve the problem by:
 Define, document, and communicate it
 Ensures everyone is using it, and using it correctly
 Ensures the software and system architectures are in synchronization
 Ensures management understands it (to the detail necessary)
 Identify and interact with stakeholders to make sure their needs are being met
 Ensures that the architecture is not only the right one for operations, but also for
deployment and sustainment
 Resolve disputes and make tradeoffs
 Resolve technical problems
 Understand and plan for evolutionary paths
 Plan for new technology insertion
 Manage risk identification and risk mitigation strategies associated with the
architecture

Competency Conclusion
As you become more senior in architect role, it is less about what you know
and more and more about who you are -- your personal characteristics.

To Build Architecture
 Goals, architectural goals tend to address the following
questions:
 What is the expected lifespan of the system?
 Will the system need to respond to technological changes
over that time, such as new versions of middleware or
other products?
 How frequently is the system expected to adapt to change?
 What changes can we anticipate in the future, and how can
we make them easier to accommodate?
