For complex, integration-heavy Service Cloud programs, Salesforce best practice is to deliver iteratively with short, inspect-and-adapt cycles so that integration touchpoints can be validated early, risks reduced, and scope refined as the team learns. This aligns to Agile methodologies (such as Scrum or Kanban) rather than linear, big-bang delivery.
The Service Cloud Consultant Study Guide under Implementation Strategies emphasizes planning for incremental releases, continuous stakeholder feedback, and frequent validation across systems—key characteristics of Agile delivery. This approach ensures early visibility into integration challenges and allows for adjustments throughout the project lifecycle.
In contrast, Waterfall follows a sequential design process with late-stage testing, which introduces higher risk for complex, multi-system implementations. Six Sigma is a process improvement framework focused on reducing defects, not a delivery methodology suitable for Salesforce implementations.
