An iterative rollout approach is a way of delivering a product or service incrementally, rather than in one big launch. This allows the project team to test and validate the product with real customers, get feedback, and make adjustments as needed. This reduces the risk of delivering a product that does not meet the customer's needs or expectations, or that has major defects or errors. By delivering the highest business value earlier, the project team can also demonstrate the benefits of the new model to the executives and stakeholders, and gain their support and confidence. An iterative rollout approach is consistent with agile project management principles, which are recommended for high-risk and high-uncertainty projects. References:
