Understanding Project Requirements

What Are Requirements?

Requirements define what a project should do. They are the foundation of any successful software project.

Types of Requirements

1. Functional Requirements

What the system should do:

• User authentication and authorization
• Data input and output
• Business logic and calculations
• Reporting and analytics

2. Non-Functional Requirements

How the system should perform:

• Performance: Response time, throughput
• Security: Authentication, encryption, data protection
• Scalability: Handling growth in users and data
• Availability: Uptime, redundancy, disaster recovery
• Usability: User experience, accessibility

Requirements Gathering Process

Step 1 — Identify Stakeholders

• Clients and customers
• End users
• Project managers
• Development team
• QA team

Step 2 — Collect Requirements

• Interviews with stakeholders
• Surveys and questionnaires
• Workshops and brainstorming sessions
• Document analysis
• Observation of current systems

Step 3 — Analyze and Prioritize

• Must have: Essential for launch
• Should have: Important but not critical
• Could have: Nice to have
• Won't have: Out of scope

Step 4 — Document Requirements

# User Story Example
As a registered user,
I want to reset my password,
So that I can access my account if I forget my password.

# Acceptance Criteria
- User can enter their email address
- System sends a password reset link
- Link expires after 24 hours
- User can set a new password

Step 5 — Review and Validate

• Review with stakeholders
• Validate feasibility
• Get sign-off

Common Pitfalls

• Scope creep: Adding features without proper evaluation
• Vague requirements: Unclear or ambiguous specifications
• Missed stakeholders: Not including all affected parties
• Assumptions: Assuming things without verification
• Technical debt: Rushing without proper planning
