Day 25 - Tracking UX Metrics

What is a performance metric?  Metrics measure a project or product's performance. They are the data, numbers, and goals used to track the health and success of a project.

Measuring user experience success:

1. Track the metrics related to your top goals.
2. Determine what's most important to track and keep the number of metrics very small, probably one metric. For example, are you focused on retention or growth? How much will improvement in user experience help? 
3. Engagement. Track things like how often customers use the service, upload photos, tag content, search with your product, interact with the features, sharing, etc.
4. Track happiness. Create user surveys to examine what people think.
5. Consistently measure and check user comments, feedback, ratings, and reviews to see where your users' pain points are so you can address them.
6. Task success. Are users completing tasks, abandoning workflows or getting errors.
7. Time. How much time do people spend using your service.
8. Compare conversion rates or sales before and after the updates to the user experience using metrics such as average revenue per user (ARPU).
9. ROI (return on investment) is always calculated in terms of increase or decrease of some key variable such as increased sales, customer loyalty, lower attrition, increased engagement, decreased support costs, etc.

Day 22 - Mobile Basics: Bluetooth Low Energy

Bluetooth low energy or BLE is ideal for applications such as sensors, remote controls, smart watches, health measurement apps, and fitness tracking apps to name just a few use cases. Devices such as Fitbit wristbands pair with your phone using Bluetooth LE to track your body's exercise and sleep patterns.

Bluetooth LE is a technology built in to devices that uses far less power than standard Bluetooth connections that can last for "years" without needing battery replacement or recharge.  Rather than a persistent connection, BLE uses short bursts of data and powers itself off again when finished sending the data. So it's low energy.

The Bluetooth LE on your device can be used to pinpoint your precise location.  There are BLE devices to track your wandering pets, your lost keys, and many more on the way.

How many use cases you can think of for creating new services or apps for Bluetooth LE?  Make your own list or share them in the comments area.
