3. Elicitation/Requirements Gathering
is the practice of collecting the requirements of a system from users, customers
and other stakeholders.
 Prepare for Elicitation
 Conduct Elicitation Activity
 Document Elicitation Results
 Confirm Elicitation Results
4. Types of Requirements
Business Requirements
• Sounds Like a high-level business goal or objective.
• Example: “Expand the number of customers we have by 50% next year.
• Why it’s important: Establishes the business case for the project.
Types of Requirements
Use Case
• Sounds like the name of a process, collection of individual steps.
• Example: “Customers will be able to plan an adventure.”
• Why it’s important: Use cases are containers for functional requirements in context.
Types of Requirements
Quality Attribute
• Sounds like a quality characteristic that a system should posses, e.g.
performance, security, etc.
• Example: The system should be able to accommodate 100 simultaneous users.
• Why it’s important: The system should ensure a certain quality of service to
users.
Types of Requirements
Data Definition
• Sounds like information the system will create, update, read, or delete.
• Example: If I enter a name I want to see their address.
• Why it’s important: A system can’t work without data.
Types of Requirements
Functional Requirement
• Sounds like a single statement of one individual function. (Will, or Shall
statements)
• Example: With the correct 4 digit pin the system will allow the user access the
ATM machine.
• Why it’s important: These are the detailed functional requirements of the
system.
Types of Requirements
External Interface
• Sounds like getting information from or giving information out.
• Example: Perform a search, get a result.
• Why it’s important: Almost every system communicates with something
else in the universe.
Types of Requirements
Design Constraint
• Sounds like a limitation of the solution or implementation.
• Example: “The UI has to function with IE8 and above.”
• Why it’s important: Design constraints must be considered when the solution
is determined.
Types of Requirements
Solution Idea
• Sounds like a solution or statement of design.
• Examples: We will only be able to accept electronic applications.
• Why it’s important: Work backwards from the solution idea to the
underlying business requirements. “What's the problem we are trying to
solve?”
Types of Requirements
Business Rule
• Sounds like a policy determined by management, or some regulatory agency,
that limits what people or an automated system can do.
• Example: “Customers must be registered before they can use the ATM
machine.
• Why it’s important: System must ensure compliance with all business rules.

Organizing Requirements
 Creating a Requirements Document is really about
packaging the requirements
 Create a requirements set or package that reflects the
requirements for a particular system, sub-system, or a
number of systems together
 Define requirements that are applicable to the entire system;
global requirements
 Define requirements that are specific to sub-systems and eventually to
individual use cases
