  <ul>
    <li>Start with MVP (Minimum Viable Product) approach</li>
    <li>Use platform-based development (AWS IoT, Azure IoT)</li>
    <li>Leverage open-source frameworks (FreeRTOS, Zephyr)</li>
    <li>Partner with experienced development firms for faster execution</li>
  </ul>

  <h2>7. Timeline Expectations</h2>
