My phone telling me how much power in the battery I have left is a form of KPI I use on a regular basis. The color and image of the battery icon is specific and measurable. Charging my phone for more battery life would be achievable. Lastly, It’s relevant to how much use I can get out my phone in a specific timeframe.
For number 3, I’ve done this a lot in the pre-autosave days. If I’m in a rush the last thing I will think about doing is setting up a backup to a database I’m working on. If it’s not a personal database, I can’t see anyone making this mistake. It’s just too risky not backing up all the data that’s being changed.
