Use Case 2.1 Activities

INTRODUCTION TO USE CASE MODELING


What

is a

model?


Think big,

Build in many steps

IVAR JACOBSON


UML can tell you how to make

well-formed models, but it

doesn’t tell you what models

you should build or when you

should create them.

JAMES RUMBAUGH


A fool with a tool

is still a fool.

GRADY BOOCH


What questions

should a

Use Case

answer?


• How should an actor and the system interact?

• What does a Software Developer need to build?

• What does a QA analysts need to test?

• What questions does a use case diagram answer?

• How do actors and use cases interact?

• What is the value of that interaction?

What Questions Does a Use Case Answer?


What is the

value of a

Use Case?


• They ensure your requirements are holistic

• They are easy to write and understand

• They are easy to reuse

• In Waterfall they can clearly define the solution that needs to be built

• In Agile they can do the same, or clearly define what has been built

• They are a firm foundation for a library that documents what has been implemented

What is the Value of a Use Case?


What is Use Cases 2.1?


• Use Cases were introduced almost 30 years ago

• Business Analysis, Agile, and many other practices did not even exist

• Use Case 2.0 was introduced by Ivar Jacobson in 2011 to make practices lighter,

scalable, more versatile, and easier to use

• This class blends Jacobson’s method with practices used across many organizations

today

• We will break down the whole practice into a series of simple steps and then use them!

What is Use Cases 2.0?


•Keep it simple by telling stories

•Understand the big picture

•Focus on value

•Develop in small steps

•Deliver in increments

•Build at the right level of detail
