The IREB Certified Professional for Requirements Engineering is a
standardized qualification for requirements engineers and business
analysts.

The certification is based on a multiple-choice exam covering the
freely available syllabus. The Foundation Level exam has no pre-
requisites. The education program is offered more than 10 countries

The exam for the Foundation Level has a theoretical nature and requires
knowledge especially in the field of requirements engineering with focus
on, but not exclusively for, the specification of software products.

As of October 2011, there were over 7100 IREB Certified
Professionals for Requirements Engineering worldwide.

Requirements engineering as the first step of system development crucially
influences the success of the development project.

The four core disciplines of requirements engineering are: elicitation,
documentation, verification and validation management.

Professionalism in requirements engineering avoid defects in system
analysis and establishes a structured proceeding from project idea to a
valuable set of requirements.

An enterprise produces parts for the automobile industry. The executive board
has decided that the firm‟s product catalog shall be available on the Web,
allowing direct electronic ordering via Web. An important large customer was
pushing the idea. The firm has accordingly launched a development project. The
requirements specification has just been released, and the project leader
decides to have the specification reviewed in a technical review. As experts she
names four co-workers from the testing department, who did not participate in
the production of the specification.

Evaluate the decisions and choices of the project leader by marking each of
them as suitable or unsuitable.
(2 points)
suitable unsuitable
The moment for the review is well chosen.
A document review is a suitable testing procedure for the current situat
