Final answer:
The classroom strategy is based on the spiral software process model, an iterative process that allows continuous improvements and evaluations of a design, potentially leading to higher quality outcomes but requiring careful time and resource management.
Step-by-step explanation:
The classroom strategy is based on the spiral software process model. A spiral design process involves iterations where changes are made, evaluated, and then further improved upon. This model aligns with the iterative nature of many design projects, where prototypes are developed, tested, and then refined based on the understanding gained from evaluations.
The spiral model is beneficial as it often results in a much better end design compared to the initial concept. However, it also has the disadvantage of requiring significant time and resources for each iteration, possibly leading to projects being overdue and going over budget if not managed carefully.
