DOORS/AnalystModeling for Requirements Engineering

IBM Software Group | Rational software

What’s your view?

”A picture paints a thousand words”

”A thousand readable words could have been put in the space of this one unreadable drawing”

or...

It is not ”either-or”, it is both. Hence: DOORS/Analyst


Requirements Engineering Challenges

Requirements elicitation Elicitating all requirements from all stake-holders

Define scope and boundaries for the problem as well as the suggested solution

Requirements clarification Specify unambiguous requirements

Attain mutual understanding of requirements among involved stakeholders

Foundation for reuse Shorten development times by being able to reuse information created early later in the

development lifecycle


Do You Visualize Requirements Today?

When working with requirements do you create a picture – a mental model – of how the system should work?

In requirements gathering workshops do you produce storyboards, Microsoft ® PowerPoint ® pictures or whiteboard scenarios?

When communicating with other team members, do you draw pictures to explain how a requirement should be understood?


Introducing DOORS/Analyst Industry-first Visual Modeling Inside a Requirements Management Tool


DOORS/Analyst Capabilities

Sketching diagrams or defining complete models

Automatically creates diagrams from textual requirements and keeps them in synch

Create!

Save!


DOORS/Analyst Capabilities

User-defined, domain-specific symbols create rich descriptions and overviews

Maintains DOORS security levels, access control, baselining

Links DOORS requirements to model for quick navigation and traceability


DOORS links from textual objects tomodel elements


Model ‘awareness’ with non-intrusive syntactic and semantic checks


Benefits of DOORS/Analyst

Low learning curve and easy to get started No need to worry about keeping the different representations – visual and

texual – up to date

Based on familiar usability paradigms and standardized pictures and diagrams

Improved requirements elicitation Get richer input from customers

Less ambiguous requirements

Easier to demonstrate requirements to end users

Maintained traceability of requirements Quickly find the relevant model element via bi-directional links from textual

requirements


Benefits of DOORS/Analyst (cont) Enhanced feedback and buy-in from stakeholders

Elicit better feedback from key people in the organization

Involve also non-technical people in the requirements management process

Strengthened collaboration with other team members Quickly embellish requirements with sketches

Ensure that requirements are completely understood by implementers

Symbols and diagrams used are familiar to most system and software developers

Simplified international cooperation Visual models provide ”common ground” for all

Transfer model to TAU/Developer

Refine model, simulate and generate final application

Establish a traceability chain to the original information in DOORS while models are transferred


Summary: DOORS/Analyst

Easy-to-learn, yet powerful visual modelling inside DOORS

Synchronizes and stores diagrams together with textual requirements

Maintains traceability between text and models

Provides customizable symbols

Enhances requirements quality, simplifies internal and external communication, and jump-starts systems development
