Requirements elicitation techniques in Software Engineering - Mini Project: Build & Apply

Requirements Elicitation Techniques

📖 Scenario: You are part of a software development team tasked with gathering clear and complete requirements for a new project. To do this effectively, you need to understand and apply different requirements elicitation techniques.

🎯 Goal: Build a simple structured list of common requirements elicitation techniques with brief descriptions. This will help you remember and explain these techniques to your team.

📋 What You'll Learn

Create a dictionary named elicitation_techniques with exact keys and descriptions

Add a variable named priority_threshold to filter important techniques

Use a dictionary comprehension to select techniques with priority above the threshold

Add a final summary string describing the selected techniques

💡 Why This Matters

🌍 Real World

Requirements elicitation is a key step in software development to understand what users and stakeholders need. Using structured techniques helps gather clear and complete requirements.

💼 Career

Software engineers, business analysts, and project managers use these techniques to ensure the software meets user expectations and reduces costly changes later.

1

Create the initial data structure

Create a dictionary called elicitation_techniques with these exact entries: 'Interviews' with description 'Direct discussions with stakeholders', 'Surveys' with description 'Questionnaires to gather information', 'Workshops' with description 'Group sessions to explore requirements', 'Observation' with description 'Watching users perform tasks', and 'Document Analysis' with description 'Reviewing existing documentation'.

Software Engineering

# Create the elicitation_techniques dictionary with exact keys and descriptions
# Your code here

Need a hint?

Use a Python dictionary with the exact keys and string values as described.

2

Add a priority threshold

Create a dictionary called technique_priority with these exact entries: 'Interviews': 5, 'Surveys': 3, 'Workshops': 4, 'Observation': 2, and 'Document Analysis': 1. Then create a variable called priority_threshold and set it to 3.

Software Engineering

elicitation_techniques = {
    'Interviews': 'Direct discussions with stakeholders',
    'Surveys': 'Questionnaires to gather information',
    'Workshops': 'Group sessions to explore requirements',
    'Observation': 'Watching users perform tasks',
    'Document Analysis': 'Reviewing existing documentation'
}
# Create technique_priority dictionary and priority_threshold variable
# Your code here

Need a hint?

Use a dictionary for priorities and a simple integer variable for the threshold.

3

Filter techniques by priority

Use a dictionary comprehension to create a new dictionary called important_techniques that includes only those techniques from elicitation_techniques whose priority in technique_priority is greater than or equal to priority_threshold.

Software Engineering

elicitation_techniques = {
    'Interviews': 'Direct discussions with stakeholders',
    'Surveys': 'Questionnaires to gather information',
    'Workshops': 'Group sessions to explore requirements',
    'Observation': 'Watching users perform tasks',
    'Document Analysis': 'Reviewing existing documentation'
}

technique_priority = {
    'Interviews': 5,
    'Surveys': 3,
    'Workshops': 4,
    'Observation': 2,
    'Document Analysis': 1
}

priority_threshold = 3

# Your code here

Need a hint?

Use a dictionary comprehension with elicitation_techniques.items() and check priority with technique_priority[technique].

4

Add a summary description

Create a string variable called summary that says exactly: 'Selected techniques are Interviews, Surveys, and Workshops.'

Software Engineering

elicitation_techniques = {
    'Interviews': 'Direct discussions with stakeholders',
    'Surveys': 'Questionnaires to gather information',
    'Workshops': 'Group sessions to explore requirements',
    'Observation': 'Watching users perform tasks',
    'Document Analysis': 'Reviewing existing documentation'
}

technique_priority = {
    'Interviews': 5,
    'Surveys': 3,
    'Workshops': 4,
    'Observation': 2,
    'Document Analysis': 1
}

priority_threshold = 3

important_techniques = {technique: desc for technique, desc in elicitation_techniques.items() if technique_priority[technique] >= priority_threshold}

# Your code here

Need a hint?

Assign the exact string to the variable summary.
