Teams Develop Solutions Faster with Rational

CTS6-09 Rational Approach.ppt 2

How do we do that?

Friendly Finance

As we just saw…..we improved productivity of the programmers, but it is ALSO important to improve the productivity of the ENTIRE development team.

Integration between ClearQuest and RequisitePro- No requirements are missed by the team- Project is automatically documented

Reduces project risk- Enforces a structured process - Projects are properly managed- Real time project status

What is UML

The UML is the standard language for visualizing, specifying,constructing, and documenting the artifacts of a software intensive system.

The UML specification can be downloaded from: http://www.omg.orgUML = Unified Modeling Language

Rational Software lead the effort to standardize UML and thenprovided tools that delivered UML Modeling

Let’s build a giant Lego Castle !

Can you build this castle in 30 minuteswithout ANY instructions?


Why Use Modeling ?

FACT 1: Most developers just want to code to get the job done.FACT 2: Development time can be drastically reduced by proper

software modeling and documentation.

1. Efficient team development

2. Increase QUALITY of code? Fewer bugs, less rework

3. Fully understand the system / application before we code

4. Fully document system / application? Easier for others to maintain and understand? Changes can be easily be made

5. Increase re-use of code


UML Diagrams

1. Use Case Communicates to the customer what functionality is in the project scope, and who the system actors are.

2. Activity Shows the workflow in a business process.

3. Collaboration Shows the objects participating in a scenario of a use case, how the objects are related, and the messages sent between the objects.

4. Sequence Shows the objects participating in a scenario of a use case, howthe objects are related, and the messages sent between the objects. Similar to collaboration diagram but in a different format.

5. Class Diagrams the classes or subset of classes in a system along withtheir relationships, attributes and operations.

6. Statechart Shows the dynamic behavior of an object, including the states that it may exist in.

7. Component Shows the physical components that make up a system.

8. Deployment Addresses how the system will be deployed.

Sequence Diagram – The “Project View”

Developers

Developer opens ClearQuest to see requirement and opens RequisitePro to see the use case requirement. Uses integration with XDE to identify the effected code.

Productivity is enhanced? Requirements are quickly identified? Easily identify objects to change? Visual UML diagrams document system architecture
