The document discusses requirements analysis, which is also known as requirements engineering. It is critical to the success of a development project to properly analyze requirements and document them. Stakeholders are persons or organizations that have a valid interest in the system, and they are not limited to just the developing organization, but can also include anyone who uses the system, benefits from it, purchases it, regulates it, or is opposed to it. A System Context Diagram shows the interactions between a system and other actors it is designed to interface with, and helps understand the system's context.

1. CHAPTER 5
Requirements analysis

2. = Systematic requirements
analysis is also known as
requirements engineering

3. =>The term requirements analysis can
also be applied specifically to the
analysis proper, as opposed
documentation of the requirements,
it is also a critical to the success of a
development project

4. Stakeholders
– are persons or organizations
(legal entities such as
companies, standards bodies)
which have a valid interest in
the system.

5. It is increasingly recognized that
stakeholders are not limited to the
organization employing the analyst.
Other stakeholders will include:
•anyone who operates the system (normal
and maintenance operators)
•anyone who benefits from the system
(functional, political, financial and social
beneficiaries)

6. •anyone involved in purchasing or procuring the
system. In a mass-market product
organization, product management, marketing
and sometimes sales act as surrogate consumers
(mass-market customers) to guide development
of the product
•organizations which regulate aspects of the
system (financial, safety, and other regulators)
•people or organizations opposed to the system
(negative stakeholders)
•organizations responsible for systems which
interface with the system under design

7. System Context Diagram
A System Context Diagram
(SCD) in software engineering
are diagrams that represent the
actors outside a system that
could interact with that system

8. System context diagrams are
related to Data Flow Diagram, and
show the interactions between a
system and other actors with which the
system is designed to interface and it
can be helpful in understanding the
context which the system will be part
of.
