What Architecture Design is about:

Specifies, refines, updates and makes available a formal approach to implement solutions, necessary to develop and operate the IS architecture. Identifies change requirements and the components involved: hardware, software, applications, processes, information and technology platform. Takes into account interoperability, scalability, usability and security. Maintains alignment between business evolution and technology developments..

The concept of architecture in ICT doesn't actually differ form architecture in constructing buildings or any other structures. It is the process of development of methodical specifications, models and guidelines within a coherent framework. This LU provides a general overview of the perspectives of an ICT Architecture and of the requirements for designing and implementing a consistent ICT environment.

Implementing the ICT Architecture requires to  document, publish and control the standards defined according to the Architecture for the enterprise. It includes the development at different levels of models and patterns to support new implementations, and the evaluation of complex situations, in order to ensure consistency. This LU provides guidelines to manage the Architecture in the enterprise.

An ICT Architecture is not fixed over time. Business rules and requirements, technology and best practices evolve continuously, so the Architecture must be regularly reviewed based on factors such as needs, opportunities, risks and costs. In this LU the drivers for evaluating the current Architecture and the possible new rules to adopt are discussed.

Enterprise architecture (EA) is a "practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy". Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes. This LU introduces the mostly used methods and frameworks for analysing and describing the Enterprise Architecture, and the impacts on ICT Architecture.

Fast evolving technology implies challenges and opportunities for the enterprise. The digital transformation can even change the way the organisation is doing its business. This LU describes the drivers to consider for consistently rethinking the business strategy through innovation.
