Hello, I am bugfree Assistant. Feel free to ask me for any question related to this problem

Requirements Clarification & Assessment

  1. Objective:

    • Develop a predictive model to estimate food preparation times at restaurants.
    • Ensure predictions are accurate enough to optimize the delivery process and enhance customer satisfaction.
  2. Assumptions:

    • The problem is framed as a regression problem since the target variable (preparation time) is continuous.
    • The model will be evaluated based on both bias and variance to ensure optimal performance.
  3. Data Requirements:

    • Historical data on order times, preparation times, and pickup times.
    • Restaurant-specific features such as staff workload, peak hours, and menu complexity.
    • External factors such as weather conditions or special events that could impact preparation times.
  4. Stakeholders:

    • Customers: Expect timely delivery and hot food.
    • Delivery Drivers: Prefer minimal wait times and efficient routes.
    • Restaurants: Aim to streamline operations and reduce idle time.
  5. Constraints:

    • Real-time prediction capability to support live order processing.
    • Scalability to handle varying volumes of orders across multiple locations.
