# Projected KPIs Readme

*(!) If you are reading this, be warned that any model within this folder contains **ESTIMATES** in the form of projections.*

## Purpose

The `\kpis\projected` folder is dedicated to projected KPIs modelisation, which include mostly any relevant dimension and measure and time aggregation needed for transforming data into business estimates.

These are likely depending on the actual KPIs.

## Convention

- Any model within the folder `intermediate\kpis\projected` needs to follow this convention: `int_kpis_projected__{structure_type}_{time_dimension}_{relevant_entity_name}`.

For the structure type, time dimension and relevant entity name, please refer to the documentation within KPIs - it remains the same.

## Contributing guidelines

**Always KISS - Keep It Simple Stupid**: An easier model is better for debugging. If we're in need to do advanced predictions, then likely we'll need to do Machine Learning rather than just business rules.

**Always report the error**: There's multiple ways to check how good or bad is an estimate, but at least provide a simple measure for each estimate. Make sure that this estimate is based on a recent period from which we are able to retrieve the actual data (the source of truth). Make sure that this estimate can be computed in the past without any data leakage - otherwise Uri will be very, very mad.

Have fun!
