A Predictive Approach is a development approach in which the project scope, time, and cost are determined early in the project life cycle. Often referred to as waterfall, this method relies on a structured sequence of phases with defined deliverables and low tolerance for change once planning is complete.
It is best suited for projects with well-understood requirements, stable environments, and clearly defined outcomes.
Key Characteristics
- Front-Loaded Planning – Scope, schedule, and cost are defined up front
- Sequential Execution – Phases follow a fixed order (e.g., initiation → planning → execution → closeout)
- Low Flexibility – Changes require formal control procedures
- Heavy Documentation – Relies on detailed plans, baselines, and approvals
Example Scenarios
- A construction project with strict regulatory and engineering constraints
- A government contract requiring fixed deliverables and compliance reviews
- A manufacturing process setup with predefined steps and outcomes
Why Predictive Approach Matters
- Provides Clarity and Structure – Enables detailed forecasting and control
- Improves Stakeholder Confidence – Sets clear expectations early in the process
- Supports Compliance – Meets needs of highly regulated or contract-driven environments
- Enables Performance Measurement – Aligns with baselines for variance analysis
