ETAPA 1. ENTENDIMIENTO DEL NEGOCIO

SITUACIÓN ACTUAL

Datos de ventas, ordenes, sitios, personas, movimientos asociados a ventas de los últimos tres años.

Recursos computacionales para análisis: R, tableau, SSMS.

Requerimientos

Resultados visuales y fáciles de comunicar para la toma de desiciones.

Asumimos que los datos están correctos y que no hay necesidad de revisar otro material para corregir la información. ### Riesgos Que los datos no sean correctos

Terminología

Categoría y subcategoría: hace referencia a grupos de productos que son usados para una misma función.

Ticket promedio: ventas totales dividido entre en número de ordes, siendo una representación de que tan garndes son las compras que se hacen en alguna categoría, persona, región.

Costos y beneficios

Información útil para la toma de desiciones en cuanto a los productos que se están vendiendo y las regiones de importancia para dirigir esfuerzos de marketing.

Objetivos

Objetivo 1:

Identificar productos con baja rotación en inventario: Este objetivo busca optimizar la gestión del inventario, reduciendo costos asociados a productos que permanecen demasiado tiempo almacenados o que tienen poca demanda. Criterios de Éxito: ● Detectar productos con pocas unidades vendidas en los últimos 6 meses. ● Identificar productos que han permanecido en inventario sin movimiento durante los últimos 3 meses.

Objetivo 2:

Determinar regiones prioritarias en ventas para dirigir esfuerzos de marketing: Este objetivo busca conocer qué regiones generan mayores ingresos, para enfocar campañas de marketing y estrategias comerciales. Criterios de Éxito: ● Identificar los estados o países donde los ingresos por ventas han aumentado en el último año. ● Calcular el ticket promedio por cada región, determinando los más rentables o forma de flujo.

Criterios de exitos de minería.

1. Identificar productos con baja rotación en el inventario para optimizar espacio y reducir costos..
2. Analizar tendencias de venta por región para entender dónde enfocar esfuerzos comerciales.
3. Determinar qué tipo de regiones generan mayor rentabilidad.

ETAPA 2. ENTENDIMIENTO DE LOS DATOS

Base de datos: AdventureWorks

Naturaleza de los datos: La base de datos AdventureWorks OLTP es un sistema transaccional utilizado para simular un entorno de negocio real. Contiene datos de ventas, productos,inventarios. Es usada usualmente para prácticas de desarrollo, modelado relacional y consultas

Tablas a utilizar:

● Tabla: Production.Product Campos de uso: ProductID, Name, ProductNumber, SafetyStockLevel, ReorderPoint Justificación: Información básica de productos, útil para identificar qué productos tienen baja rotación o están sobrestockeados.

● Tabla: Production.ProductInventory Campos de uso: ProductID, LocationID, Quantity Justificación: Permite conocer el inventario actual.

● Tabla: Sales.SalesOrderHeader Campos de uso: SalesOrderID, CustomerID, OrderDate, SubTotal Justificación: Útil para obtener las fechas de ventas, lo que permite analizar tendencias temporales.

● Tabla: Sales.SalesTerritory Campos de uso: TerritoryID, Name, CountryRegionCode Justificación: Permite agrupar y analizar ventas por región o país
