How do you estimate effort for Scrum tasks or stories?

Short answer: login screen might be a 2-point story (simple, well understood). A feature with integrations nd security considerations may be 8 points due to complexity and risk. Pro Tip: void estimating in hours — it introduces false precision. Focus on relative effort, not duration.

Real-world example (ShopNest)

Agile for ShopNest means ship a thin checkout slice every sprint, get feedback, then improve—not a 6-month big-bang release.
