The document discusses picturing architecture using UML diagrams. It states that visualizing software architecture through diagrams helps communicate design effectively and avoids rework. Different types of UML diagrams like use case diagrams, sequence diagrams, and deployment diagrams are presented as ways to picture architectures. Benefits of this approach include improved readability, planning and standardization of the software application design.

What is Architecture?
 Derived from Greek word ἀρχιτέκτων (arkhitekton)
 Defined as both process and product of planning, designing and constructing
buildings and other stuff.
 In a day to day language, architecture means “building”

5. CONFIDENTIAL & RESTRICTED
Definition of software architecture
“The fundamental organization of a system
embodied in its components, their
relationships to each other and to the
environment and the principles guiding its
design and evolution”

Designing in an agile world !!

7. CONFIDENTIAL & RESTRICTED
Why Agile?
 Individuals and interactions over processes and tools
 Working software over comprehensive documentation
 Early detection of issues in the developed software
 Faster process of development phase
 Customer collaboration over contract negotiation
 Responding to unanticipated changes during the development phase

8. CONFIDENTIAL & RESTRICTED
A software application is…
 Huge pile of code which ultimately result in numbers.
 It is impossible for developers to design a software by visualizing the numbers
which will be actually read by the computer.

Solution – Picture the architecture

11. CONFIDENTIAL & RESTRICTED
How to picture architecture?
 Using UML
 UML acts as an effective programming language itself
 Application design can be leveraged from the mistakes done and corrected
during the design phase using UML.
 This will absolutely avoids a lot of rework during the development phase.

Organizing User Stories based in Epic
 An epic is a body of work that can be broken down into specific tasks
(stories/User stories) based on the needs/request of customers/end users.
 Story (User story) is nothing but a narrative that takes an user through some
process that results in a valuable outcome.
