Getting Started with Rational Doors Tutorial

If you’re new to Rational DOORS, the initial learning curve can feel steep. However, by

breaking down its components and functions, you can quickly become comfortable

navigating the environment.

Understanding the User Interface

One of the ﬁrst steps in any rational doors tutorial is familiarizing yourself with the user

interface (UI). The UI is organized around modules, objects, and attributes:

**Modules:** Think of modules as containers or documents holding your

requirements.

**Objects:** Each object typically represents a requirement or a piece of

information within a module.

**Attributes:** These are properties associated with objects, such as requirement

ID, status, priority, or description.

Navigating through modules and eﬃciently searching for speciﬁc objects is a daily task in

Rational DOORS. Learning how to customize views and ﬁlters will improve your

productivity.

Creating and Editing Requirements

To begin managing requirements, you’ll want to know how to create new modules and

add objects:

Open Rational DOORS and create a new module.

Add objects to the module, each representing an individual requirement.

Fill in attributes for each object to detail the requirement’s speciﬁcs.

Use rich text formatting to make descriptions clear and easy to read.

Editing existing requirements involves updating attributes or object content, which can be

done directly in the module view. Rational DOORS supports bulk edits and copy-pasting,

which is helpful when dealing with large datasets.

Organizing Requirements for Better Traceability

Traceability is arguably one of the most powerful features of Rational DOORS, allowing

stakeholders to track the lifecycle of each requirement and its relationships with other

project elements.

Using Links to Establish Relationships

In Rational DOORS, you can create links between objects to represent dependencies,

derivations, or satisfaction of requirements. For example, a high-level requirement can be

linked to detailed sub-requirements or test cases.

These links provide a visual and systematic way to ensure nothing falls through the cracks

during development. Understanding how to create, manage, and visualize these links is

crucial in a rational doors tutorial.

Traceability Matrices

Traceability matrices are tabular reports that map requirements to other artifacts.

Rational DOORS allows you to generate these matrices, which are invaluable during audits

or reviews. They help conﬁrm that all requirements have been addressed and properly

tested.
