K-Factor (Virality Factor)
K-Factor is a metric that measures how effectively an app attracts new users. It is used to describe your app’s virality or how much improvement it has on driving engagement for each existing user. K-Factor defines how popular your product is, by comparing it to the average number of people who install and use it.
Kanban is an organizing method that generally divides workload into columns as to do, doing, done. It is a dynamic method invented to help teams more efficiently complete their work. Rather than only doing a bit of work at a time, every column gives the team an idea of how much work is being accomplished at any given moment. This is best practice because it creates an awareness of how much work is being completed.
