How is Estimation Done in a Scrum Project?
The estimation of user stories is done based on their difficulty
A particular scale is used to assess the difficulty of the user stories. Some type of scales are:
Numeric Sizing (1 - 10)
T-shirt Sizes (S, M, L, XL…)
Fibonacci Series (1, 2, 3, 5, 8…)
Dog breeds (Great Dane, Chihuahua…)
