Lecture 7 - Requirement Analysis: Benefits and Strategies

Question 1

INTRODUKTION:

What is the purpose of this lecture?

Answer 1

Analyse a business process and suggest how the process might be improved using IT, define the requirements to IT systems improving the process, and design the external characteristics of these systems.

Some of the major challenges are:

• Collaborating with users
• Understanding a business process

Question 3

THE BASIC CONCEPTS:

Explain Benefits dependency network (BDN).

Answer 3

The BDN provides the framework for explicitly linking the overall investment objectives and required benefits (the ends) with the business changes (the ways) necessary to deliver those benefits and the essential IT capabilities (the means) that enable these changes.

Question 4

THE BASIC CONCEPTS:

Explain Problem-based and Innovation-based intervention.

Innovation-based intervention (projects): ways and means-driven because the goal is to discover better ways of working by utilizing IT (the means) or new ways of e.g. organizing (the ways).

Question 5

THE BASIC CONCEPTS:

Explain Requirements engineering (RE).

Answer 5

The broad spectrum of task and techniques that lead to an understanding of requirements (to IT systems).

Question 6

THE BASIC CONCEPTS:

Explain Functional and Non-functional requirements.

Answer 6

Functional requirements: the calculations, information etc that the system has to deliver.
❑ Non-functional requirements: such as security, usability, performance etc.

Question 7
