LG 2-3 use IREB terms and classification

[Johannes Hochrainer]

The learning goal 2-3 uses the terms “technological factors”, “organizational factors” and “regulatory factors”.

I suggest to use the term “constraints” instead because this is also standard in IREB. So the new wording could be:
• technological constraints
• organizational constraints
• regulatory constraint

It would also be helpful to use the following structure for the influencing factors:

Influencing Factors:

• Requirements
  • Functional Requirements
  • Quality Requirements
  • Constraints
    • Technical Constraint
    • Organizational Constraints
• Trends
• ...

Here is a quote from the iREB FL syllabus 3.1 (EU 1.1 Requirements Engineering)

In RE, we distinguish between three kinds of requirements [Glin2020]:

• Functional requirements concern a result or behavior that shall be provided by a function of a system. This includes requirements for data or the interaction of a system with its environment.
• Quality requirements pertain to quality concerns that are not covered by functional requirements, such as performance, availability, security, or reliability.
• Constraints are requirements that limit the solution space beyond what is necessary to meet the given functional requirements and quality requirements.

Although coming after the official feature freeze, we will consider this within the FL-working group.

+1 for the comment of @hoch4. We will try to update the text.

[Dr. Gernot Starke]

We heavily refactored the LG to better reflect current RE terminology and readability.
