Below’s an example of an estimation table based on the matrix of complexity, uncertainty, and effort:
| Story Points | Reference | Uncertainty | Risk | Efforts | FE Example | BE Example |
|---|---|---|---|---|---|---|
| 1 | 1. Stories that take < 0.25 day to complete 2. Stories that only involve FE OR BE 3. Stories that is clear, no need to investigate/find root cause | Low - 100% Clear | Low | Less than half a day: 1 hour or less | Small UI update that doesn’t require BE work: - Color, Font, Positioning that doesn’t require relayout - Sorting (no BE work) - Only impact 1-2 screens/controls | - Configurations only |
| 2 | 1. Stories that take < 0.5 day to complete 2. Stories that is more of FE OR BE work, the other is minimal 3. Behavioural work, involve calculation/ logics | Low - Involves some changes to current calculation/logic | Low | Around half a day to 1 day | - Calculate/Sum/Count numbers - Small UI change but on multiple screens (3 or more) | - Minor changes to existing API (Add/edit/remove fields...) - Minor change on calculations to current API |
| 3 | 1. Stories that take around 1 day to complete 2. Change behavior/calculation/logic of current function that we need to rework the function 3. New calculation/logic that is different than existing default from sources | Low - Need to spend time to check the logic/calculation/ reproduce | Low | Around 1 working Day | ||
| 5 | 1. Stories that take 1-2 days to complete 2. Only need single/simple new endpoint to complete 3. Little or no migration data needed 4. Little or no DevOps involvement | Low - Medium Some clarification needed but the main flow is clear | Medium | Around 3 working Days | ||
| 8 | 1. Stories that take half a Sprint to complete 2. New feature that requires multiple endpoints/screen 3. Need some research to figure out solutions 4. Migration data needed 5. Medium Server/DevOps involvement | Medium - High - Completely new feature - Need some research to figure out solution | Medium → High - Follows current architecture design - Might impact other feature(s) - Might need migration of data | Around 5 working Days | ||
| 13 | 1. We are not sure if it works 2. Need leaders to take a look into new approach/solution and test to see if it works 3. POC work 4. Architecture change and/or new coding approach | High - Research/POC/ Architecture Stories | High - We are not sure if it work or not | If cannot deliver in a working week, please break it down |
