Who am I?

Stefan Sturm, Managing Director of IREB GmbH

What is the IREB GmbH?

What is the IREB e.V.?

International Requirements Engineering Board (IREB) e. V.

Operating company of the IREB e.V.

The importance of RE

• Publications reveal that software projects

still 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:

up to 100 times higher

A profession with a long tradition

23rd IEEE Requirements Engineering Conference – Ottawa 2015

21st REFSQ conference – Essen 2015

14th REConf – Munich 2015 – over 400 participants

But….


Is it really well established?

We are doing Business Analysis,

not Requirements Engineering!

• BA Planning and Monitoring

• Enterprise Analysis

• Solution Scope

• Requirements Elicitation

• Requirements Documentation

• Requirements Modeling

Requirements Validation (Review)

• Requirements Negotiation (Conflict

Management)

• Requirements Engineering Tools

• Requirements Management

• Solution Assessment and Validation

Requirements

Engineering!


Why “Engineering”

6

Very obvious for • Safety

• Security

• Medical

• Defense

• ….

But as well for • Consumer products

• Lifesyle

• Gadgets

• User centered

approaches

• Agile projects!

You’ve got

one shot

only!


Why should software testers care about it?

page 7 International Requirements Engineering Board e. V.

• Have you ever wondered….

• …. where the requirements for your test cases come from?

• …. why the requirements for your test cases are of poor quality?

• …. why the requirements for your test cases are incomplete?

• …. why the requirements for your test cases are ambiguous?

• …. why the requirements for your test cases are contrary to

each other?

Because of poor Requirements Engineering!


Have you ever really applied it?


• Have you ever thought about….

• …. clearly identifying the stakeholders of the system you

should test?

• …. using appropriate techniques for eliciting and documenting

requirements beyond interviews and Word documents?

• …. using appropriate techniques for requirements validation?

• ….

Have you ever thought about doing

Requirements Engineering?

Requirements Engineering and Testing

Two sides of the same coin


• Software Testers should care about Requirements Engineering

because it ….

• …. bridges the gap between business needs and

Software Testing

• …. delivers important input for

Software Testing

• …. significantly improves the quality

of requirements documents


It’s getting started!

10

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)

Increased efforts by • setting quality standards

• improving the application of RE

• demonstrating the value of RE


Common terminology, techniques and methods

11

Different implementation of Requirements Engineering • At customers, suppliers, partners

• In distributed teams at different locations, offshore, near shore

• In different industrial sectors

Problems in communication due to • different languages

• different cultures (ethnological and company specific)

Misunderstanding of “agile” • Elicitation of requirements is underestimated

• Documentation and traceability of requirements is neglected

Why do we need it?


The problem

12

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)


Challenges

13

Common understanding of terms • Within distributed teams

• Between customers, suppliers and development teams

• Over language and cultural boundaries

Elicitation, documentation and administration

of Requirements • Over release cycles

• In the context of agile development

• Within distributed teams


Challenges - continued

14

Know-How Transfer • To new employees / with staff fluctuation

• Within distributed teams……(see first point)

Different skill levels • Many practitioners do not have an education in systems/software

engineering


Certification – How does it help?

15

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

Comparison to other certification schemes

BCS Diploma in Business Analysis

• BCS is well established only in the UK

• BCS, offers a comprehensive range of business analysis certifications; but

not any advanced course in Requirements Engineering

• IREB and BCS have signed a MOU:

– Candidates that have completed the IREB’s CPRE Foundation level will

be exempt from taking the BCS Certificate in Requirements Engineering

to achieve their Diploma.

– Candidates that have completed the BCS Certificate in Requirements

Engineering will be exempt from taking the IREB CPRE Foundation

level to progress to the Advanced level.

The CPRE


IIBA CBAP /CCBA

• IIBA is well known worldwide

• Both CBAP and CCBA have high entry criteria

• 685 CCBA worldwide*

• 4866 CBAP worldwide*

• More on the strategic level whereas the CPRE is more practical oriented

*As of February 19 2015

28

The CPRE


IIBA CBAP /CCBA: What to do Describes the BA process end to end on a process level

IREB CPRE: How to do Describes the RE related tasks in great detail with concrete hands on information

29

When defining your BA process look at the BABOK® from IIBA!

When implementing the concrete RE tasks look at the CPRE from IREB!

The CPRE


IIBA CBAP /CCBA “When we were introducing structured business analysis at Sunrise, we used

the BABOK® Guide from the IIBA. This served as the basis for the definition of

our processes, which are described there in some detail. When we then wanted

to implement a training curriculum and certification program, we moved fully in

the direction of the IREB/CPRE.

The CPRE syllabi offer in our opinion a more practice-oriented approach. The

focus there is on concrete methods and techniques for requirements elicitation,

documentation, management and conflict resolution, which are not treated in

the same depth by the IIBA.

In my opinion the use of the BABOK® Guide for process definition and the

CPRE for requirements engineering training and certification complement each

other ideally.”

Christoph Wolf, Manager Business Analysis, Sunrise Communications AG
