This document discusses the challenges of software requirements engineering. It defines software requirements as descriptions of a system's features and functions based on user expectations. The main challenges are: (1) requirements often change as the world changes; (2) stakeholders have different perspectives that can conflict; and (3) effective communication between engineers and clients is difficult due to lack of time or information. Requirements engineering is inherently difficult due to these issues.

2. Context
 What is Software Requirements?
 What are the challenges in dealing with requirements?
 Requirement Changes
 Different Perspective
 Lack of Communication
 Summary

3. What is
Software Requirements?
 The software requirements are description of features
and functionalities of the target system.
 Requirements convey the expectations of users from
the software product.
 The requirements can be obvious or hidden, known or
unknown, expected or unexpected from client’s point
of view.

4. Fundamental reasons why establishing
requirements for complex systems will
always be a difficult technical and
organizational problem
What are the challenges in dealing
with requirements?

5. Changing Requirements
Differing Perspective
Lack of or Over Communication

6. Requirement Changes
 System requirement reflect the world outside
the system.
 As this constantly changing then the
requirement will inevitably also change.
 It is often difficult to understand the
implications of change for the requirements as
a whole.

7.  Technology changes
 Organizational
changes
 Market changes
 Economic changes

8. Different Perspective
 Different perspective are not consistent
and different stakeholders will want
different things from a system.
 It is inevitable that some requirements
will be conflicting so that it is impossible
to satisfy all stakeholder requirements
without compromise.

10. Lack of Communication
 Stakeholders are too busy
 Unable to get more information
 Not able to update client

11. Summary
Requirement engineering is an inherently
difficult process
Issues that contribute to this difficulty are
- Changing requirement
- Differing views of system stakeholders
- Lack of communication between
engineer and client
