The Importance ofThe Importance ofGood Requirements

The Requirements Effect

Study after study has

shown that clear,

accurate and

complete

requirements have the

biggest impact on Waste 46% of your time

Faulty requirements and low requirements maturity:


biggest impact on

project success.

IAG Consulting found

that faulty

requirements can eat

up 39% or more of

your resources. Deliver fewer projects on time and on budget

Waste 39% of your development budget

Only a third of projects

succeed

� Systems and software

projects with poor

requirements experience

more defects, delays and

cost overruns

� 68% of projects are delivered

32%

68%

� 68% of projects are delivered

late, over budget, or not

according to requirements.

� Less than a third are

successful.

� 24% are cancelled before

they are completed, or

delivered but never used.

Understanding your internal

customers' software

requirements is crucial to

delivering the right solutions

to:


� Meet their needs

� Keep the organization running effectively

The Effect of Requirements Analyst Capability

The requirements analyst capability is the most

significant contributor to project effort.

� Best requirements analysts: 29% less effort

� Worst requirements analysts: 42% more effort

The J-Curve Effect of Learning New Skills

The J-Curve Effect

� The advanced beginner has difficulty applying a new skill.

� Reverts to old ways, creating a productivity gap

The J-curve effect can occur when an Advanced Beginner struggles in applying new practices.

Avoiding the J-Curve Effect

Two critical components of

successful skill adoption

� Move staff from one stage to the next faster

� Avoid the J-curve effect


These two models can help

you:

� Breadth approach

� Depth approach

The Breadth Approach

The Breadth Approach

� Develop a solid foundation of Best Practice skills

� Refine these skills over time.

Requirements Definition Tools Overview

What to look for in a tool

� Builds upon industry best practices forrequirements definition and management

� Allows you to define your process first

• Can be configured to support your process


• From simple to complex processes

� Visually supports multiple end-to-end processesand methodologies

� Flexible, open platform based on standards

� Single collaborative platform for all stakeholders

� Low total cost of ownership and fast time-to-value

Systems Engineers’ Look at Visure Solutions IRQA

IRQA provides Systems Engineers with:

� Graphical representation of requirements

• Flows down to subsystems and components

• Functional decomposition

� Flexible import/export and roundtrip support


� Flexible import/export and roundtrip support

• Word, Excel, DOORS, and other external tools

� Open architecture with an integration platform and plug-in SDK to extend IRQA or automate tasks

• Based on standard programming languages

• Create customized requirements solutions

� Integrated risk management

• Supports FMEA/FMECA, facilitating traceability, impact analysis and reporting on risk elements

21

Systems Engineers’ Look at Visure Solutions IRQA

IRQA provides Systems Engineers (continued)

� Model-Based Systems Engineering

• Integrates with UML/SysML tools and Matlab/Simulink linking requirements with system and design models

� Requirements-based testing for verification and validation


validation

� Flexible views and traceability

� Product lines and variants support with requirements, use case and test-case reuse

� Web access for collaboration among distributed teams

� Powerful reporting

• Project dashboards and compliance documents

22

Demonstration of IRQADemonstration of IRQA

What IRQA does best

Enable collaboration

� Visual process structures improveunderstanding

� Web-based access keeps everyoneworking in a single database

� Role-based user groups and workflows


� Role-based user groups and workflowsaid ease-of-use

� Semantic analysis avoids incomplete,unclear or duplicate requirements

� Verification and validation lets everyone knows what will happen and when

� Checking out a single requirement aids team efficiency

� Discussion forums allow continued feedback

24

What IRQA does best

Support process and methods

� Information metamodel helps you define different types of requirements and their relationships with one another

� Block diagrams graphically capture, communicate and enforce requirements


communicate and enforce requirements processes, their elements and relationships

� Flexible, process-neutral approach allows you to define, control and enforce your requirements processes, across the spectrum from agile to waterfall

� Process focus improves compliance with user requirements, standards and regulations

25

What IRQA does best

Mitigate risk

� Improve requirements quality with semantic analysis

� Open architecture, integration platform and import/export capability supports requirements exchange and validation


exchange and validation

� Traceability to block diagrams and all external artifacts in a single database improves analysis and understanding of change impact

� Requirements attributes for priority, cost, risk and origin provide weight, so you can focus on the most important requirements first

� Customized workflows and alerts for transitioning requirements keep the project moving forward on schedule
