UML

Activity

Diagrams

As you explored the resour

ces, you learned how IT professionals use

different modeling tools and techniques to better understand the design of a

system. One of the most prominent modeling tools is a Unified Modeling

Language (UML) activity diagram. A UML activity diagram for a soon

to

be

designed system is like the architect’s blueprint for coding the solution; it

illustrates the workflow of a system. Due to their complex nature, UML

activity diagrams are often developed through collaboration between the

system analyst and the devel

opment team. These diagrams are high level

and can easily be understood by members of a project team who do not have

as much technical experience, such as stakeholders and project managers.

For this module’s discussion, you and your peers will reflect on U

ML activity

diagrams.

In your initial post, answer the following questions:

·

Based on what you’ve already learned about system design and

analysis, as well as the software development life cycle, discuss in what

phase you think a UML activity diagram should

be created.

·

Why is it important to develop a UML activity diagram prior to the

developers writing the code for a system?

·

How can you see these diagrams being helpful to you as a future

developer or IT professional on a project team?

·

What’s the

relationship, if any, between use case diagrams and UML

activity diagrams?

·

Reflect on what could happen if the system solution acts differently

than what is shown in the UML activity diagram.

UML Activity Diagrams

As you explored the resources, you learned how IT professionals use

Language (UML) activity diagram. A UML activity diagram for a soon-to-be

designed system is like the architect’s blueprint for coding the solution; it

illustrates the workflow of a system. Due to their complex nature, UML

activity diagrams are often developed through collaboration between the

system analyst and the development team. These diagrams are high level
