These estimates are based on the average monthly profits from the most recent year, extrapolated to the next quarter. Remember that these are projections and actual future profits may vary based on various factors.
 

Analysis of returned products and estimated defects

I suggest that notes should be made about the reasons for returning products and what problems there were in the product that led to its return, and an attempt should be made to avoid these problems to increase sales and gain trust among customers.

  • The most returned products in the last year, 2039.
     


 

  • Most Returned Products For All the Years.
     


 

  • Estimated Defect Rates for Products.

This analysis is only an estimate as the database does not have any field indicating the product defects or the reason behind the defects for each product. To address this, it is recommended to include a new field in the database that records details such as defective products, the date they were returned, and the reason for the defect of each product for more accurate analysis.
 

Inventory Analysis

Assuming that sales trends continue the following year as they are, how much product inventory would we need at the beginning of the year, to service the value of demand in the first two months?

  • Inventory Optimization: Implement a just-in-time inventory system to reduce holding costs and avoid stock-outs.

  • Data-Driven Restocking: Use sales forecasts to guide inventory restocking decisions.
