Requirements validation and verification in Software Engineering - Mini Project: Build & Apply

Requirements Validation and Verification

📖 Scenario: You are part of a software development team working on a new mobile app. Before coding starts, your team needs to ensure the project requirements are clear, complete, and correct. This helps avoid costly mistakes later.

🎯 Goal: Build a simple checklist to understand and apply the concepts of requirements validation and verification in software engineering.

📋 What You'll Learn

Create a list of initial requirements with exact given entries

Add a variable to track the number of requirements verified

Use a loop to check each requirement for validation and verification status

Add a final summary statement about the verification process

💡 Why This Matters

🌍 Real World

In software projects, validating and verifying requirements early helps avoid misunderstandings and costly errors during development.

💼 Career

Understanding requirements validation and verification is essential for roles like business analysts, software testers, and project managers.

1

Create the initial requirements list

Create a list called requirements with these exact entries: 'User login functionality', 'Data encryption', 'Responsive design', 'Offline mode', and 'Push notifications'.

Software Engineering

# Create the list called requirements with the specified entries
# Your code here

Need a hint?

Use square brackets to create a list and include all five exact strings separated by commas.

2

Add a verification counter

Create a variable called verified_count and set it to 0 to track how many requirements have been verified.

Software Engineering

requirements = ['User login functionality', 'Data encryption', 'Responsive design', 'Offline mode', 'Push notifications']
# Create verified_count variable and set it to 0
# Your code here

Need a hint?

Just assign 0 to the variable named verified_count.

3

Check each requirement for validation and verification

Use a for loop with variable req to iterate over requirements. Inside the loop, use an if statement to check if req is not empty (simulating validation). If valid, increase verified_count by 1 (simulating verification).

Software Engineering

requirements = ['User login functionality', 'Data encryption', 'Responsive design', 'Offline mode', 'Push notifications']
verified_count = 0
# Use a for loop to check each requirement and update verified_count
# Your code here

Need a hint?

Loop through each requirement and check if it is not an empty string. If so, add 1 to verified_count.

4

Add a final summary statement

Create a variable called summary and set it to the string 'Total verified requirements: ' concatenated with the string version of verified_count.

Software Engineering

requirements = ['User login functionality', 'Data encryption', 'Responsive design', 'Offline mode', 'Push notifications']
verified_count = 0
for req in requirements:
    if req != '':
        verified_count += 1
# Create summary string with total verified requirements
# Your code here

Need a hint?

Use string concatenation and convert verified_count to string with str().
