You're the PM of a startup for remote-controlled shower water heaters. Define a problem statement and plan an MVP.

Problem Statement

Users currently lack the ability to adjust their water heater settings without being physically present at the unit, leading to inconvenience and potential energy waste. For instance, a user might arrive home to a cold shower or unnecessarily heat water when not needed.

Minimum Viable Product (MVP) Plan

Product: A mobile application (iOS and Android) that allows users to remotely control their water heater.

Core Features:

1. Remote Temperature Adjustment: Users can set their desired water temperature via the app.
2. On/Off Control: Users can turn the water heater on or off remotely.
3. Scheduling: Basic scheduling functionality to set preferred heating times (e.g., morning, evening).

Target Audience:

• Homeowners and renters in the USA experiencing cold weather (typically below 20°C).
• Users who value convenience and energy efficiency.

Success Metrics:

• App download and active user rate.
• Number of remote adjustments made.
• User satisfaction scores related to convenience and control.
