The importance of RE

• Publications reveal that software projectsstill fail or have cost and/or time overruns

• Numerous studies show that about 60% of the errors of system development projects originate in the RE stage.

• Effort to fix a requirement defect:

Requirements Engineering

Time to overcome the chasm!

6

Requirements Engineering is getting started• Number of attendees in conferences increase• Number of certified professionals is growing fast• The profession “Requirements Engineer” has been officially

acknowledged in the first country (Switzerland)

Increase efforts by• setting quality standards• improving the application of RE• demonstrating the value of RE

Requirements Engineering

The problem

7

Customers, suppliers and development partners talk past each other when defining requirements

• Incomplete Requirements• Ambiguous Requirements• Missing common understanding of Requirements• Different prioritization of Requirements• Conflicts between project partners• Time and cost overruns• Missing, wrong or „gold plated“ functionality

Consequences (incomplete)

Certification – How does it help?

Why not “just” Training?

Training• Provides the fundament for Know-How acquisition• Is a recognized form of qualification• Is part of employee motivation

Certification• Common definition of terminology to improve communication

and Know-How transfer• Provides an international recognized fundament for training

Training Providers align their trainings to a “standard” – the syllabus of the certificate

• Motivates professionals to improve their skills• Motivates companies to invest in training• Offers a possibility to companies to demonstrate their expertise

Good certification gives profession prestige in IT industry eyes

•Example: testing profession•ISEB CTFL (British) introduced 1999•ISTQB (international) started 2002•Now ISTQB has issued more than 295’000 certificates worldwide

•Got 48 Member Boards•The uderstanding and prestige of testing has grown considerably!

• In Poland: approximately 6000 certificates•And RE is more important than testing…
