Professional knowledge = functioning knowledge
• is pragmatic
• results from the experience of the learner who can apply
declarative knowledge to work in practice
Reflect on
University knowledge = declarative knowledge
• is about concepts, models, methods and theories
• results from research
• forms a solid foundation for professional knowledge

Teaching for Quality Learning at University, third edition,McGrawAssignment 1: RE process and activities
• Read and analyse the article written by Nuseibeh and Easterbrook (2000).
According to the article,
“Whether viewed at the systems level or the software level, RE is a multi-disciplinary,
human-centred process. The tools and techniques used in RE draw upon a variety of
disciplines, and the requirements engineer may be expected to master skills from
a number of different disciplines.”
• Based on the article, explain
– how do the authors mean by a multi-disciplinary, human-centered RE process
and
– what kind of activities does the RE process consist of.
• Based on your present understanding of problem-solving process,
choose three topics from the article that you find
useful, interesting or challenging to understand and reflect on them.

Requirements Engineering: A Roadmap. 9
Proceedings of the Conference on the Future of Software Engineering, ACM Press, pp. 35-46.Role of RE in problem solving
Requirements engineering [Nuseibeh and Easterbrook 2000]
is the process of discovering the purpose of the system by identifying
stakeholders and their needs, and documenting those in a form that is
amenable to analysis, communication, and subsequent implementation.
Requirements engineering [Qure, CORE & Reflex projects*]
means that requirements for a system are defined, managed and tested
systematically. The purpose of RE is to ensure that the system satisfies
customer and user needs i.e.
the usage of the system provides value for customers and users.
What are commonalities and
differences of these definitions?

• Explain how requirements engineering (RE) relates to customer value
creation
• Compare traditional (Hofmann & Lehner 2001) and agile RE practices (Cao & Ramesh
2008) from the perspective of customer value creation
• Identify four good RE practices that can support customer value creation
and explain why you selected these ones

The Elements of Value: Measuring and delivering what consumers really want
Harvard Business Review, 94(9) 47-53From feature development to customer value creation Critical questions: Where is customer value created? What does customer value mean?
Customer value creation
Value is created in customers’ processes when
individual consumers or industrial users
make use of the solution.
This conclusion has been made by Christian Grönroos (2007) and
it is based on the article written by Normann and Ramirez (1993),
Grönroos C. (2007) Service Management and Marketing – Normann R. and Ramirez R. (1993)
Customer Management in Service Competition, From Value Chain to Value Constellation, 16
third edition, John Wiley & Sons, Ltd. Harvard Business Review, 71(4) 65-77.Customer value creation
Where is customer value created?
• Value for customers is
not embedded in products and systems.
• Products and systems are only facilitators
of customer value.
The focus is not on the products but
on the customers’ processes,
where value emerges for customers and
is perceived by customers.
Grönroos C. (2007) Service Management and Marketing –
Customer Management in Service Competition,
third edition, John Wiley & Sons, Ltd. Page 27Customer value
A simple formula for customer value is
• either summative i.e. benefits minus sacrifices
• or ratio i.e. benefits divided by sacrifices (Smith & Colgate 2007)
Customer
= Benefits - Sacrifices
value
Benefits and sacrifices can be both tangible and intangible.

Customer value of the MyCourses system? 20Current state: Inside-out Approach Key finding 1 Product features are seen as the core of value creation. Pitfall 1 Adding too many features to the product. Pitfall 2 Improving individual features too much. Pitfall 3 Launching stripped version of features fast. Kauppinen M., Savolainen J., Lehtola L., Komssi M., Töhönen H., and Davis A.

Company’s processes and the whole solution.
All the customer’s processes must be supported in a satisfactory way..
Some of the processes are more critical to the customer than others..
Those processes have to be supported especially carefully..

segments and user groups customer processes

Value is created in Understanding customers’ processes is
customers’ processes. the core of value creation.
28The ultimate goal of requirements engineering
is to support development teams in building
solutions
the usage of which
creates value for customers and users.
