A Request for Change (RFC) is a formalized mechanism for documenting, assessing, and approving modifications to a system, software, or process within an SDLC framework. It ensures that proposed changes are evaluated for their feasibility, impact, and alignment with project objectives. RFCs are essential in environments requiring controlled evolution of systems, such as in Agile, DevOps, or traditional Waterfall models.
Key Components of RFC in SDLC
1. Purpose
The RFC process formalizes change management to ensure:
Controlled updates to software.
Avoidance of unintentional disruptions.
Traceability of changes for auditing purposes.
2. Structure of an RFC
A typical RFC includes the following sections:
Change Title: A brief summary of the proposed change.
Requestor Details: Information about the individual or team requesting the change.
Description of Change: Detailed explanation, including reasons and expected outcomes.
Impact Analysis: Assessment of potential effects on system functionality, timelines, and stakeholders.
Priority and Severity: Classification of urgency and importance.
Approval Workflow: Stakeholders responsible for approval.
Lifecycle of an RFC
1. Submission:
An RFC is initiated by stakeholders, describing the need for change and its anticipated benefits.
Example:
{
“title”: “Add OAuth 2.0 Authentication”,
“requestor”: “Security Team”,
“description”: “Integrate OAuth 2.0 to improve authentication security.”,
“priority”: “High”
}
2. Impact Analysis:
Technical teams assess risks, dependencies, and resource requirements. It may include:
Codebase reviews.
Database schema adjustments.
Performance tests.
3. Approval:
The RFC passes through the Change Advisory Board (CAB) or designated approvers based on impact level.
4. Implementation:
Approved changes are scheduled and deployed via CI/CD pipelines or manual procedures.
5. Validation and Closure:
Post-implementation, the change is tested, and outcomes are documented for closure.
Challenges in RFC Implementation
1. Incomplete Documentation:
Missing details can lead to ambiguity in execution.
2. Prolonged Approval Processes:
Bureaucratic delays can slow down Agile workflows.
3. Underestimated Impact Analysis:
Overlooking dependencies may lead to unforeseen failures.

Significance of RFC in SDLC
1. Auditability: Provides a historical record for regulatory and compliance needs.
2. Operational Efficiency: Ensures that changes align with organizational goals.
3. Quality Assurance: Facilitates comprehensive testing and validation prior to deployment.
In modern SDLC methodologies, RFC processes are tightly integrated into Agile boards (e.g., Jira) and DevOps tools to streamline approval workflows and maintain robust versioning.
