KPI means a key performance indicator. Your KPI pretty much is how you are doing during the specific timeline. Anything you do within that organization should be match and related to your KPI.
Especially startups are either struggling to find the right KPIs for team members or not motivate them well. Either way, you should ask yourself “ What’s my KPI”? If you don’t have a clear one, create your own and share it with your boss. Tell that should be my KPI. I am a big believer in “What do you think or What do you suggest” questions.
