FSN Analysis

15/12/2023 0 By indiafreenotes

FSN Analysis is a classification technique used in inventory management to categorize items based on their consumption patterns and movement within the inventory. The FSN Analysis categorizes items into three groups: Fast-moving (F), Slow-moving (S), and Non-moving (N). This classification helps businesses prioritize their inventory control efforts and resources based on the pace of item consumption and turnover.

Categories in FSN Analysis:

  1. Fast-Moving (F) Category:

Items in the Fast-Moving category are characterized by high consumption rates and rapid turnover. These items are in constant demand, and their stock levels are depleted quickly.


  • High sales volume.
  • Frequent replenishment.
  • Short shelf life.

Management Approach:

  • Tight inventory control.
  • Frequent monitoring and reorder points.
  • Efficient order processing to meet high demand.
  1. Slow-Moving (S) Category:

Items in the Slow-Moving category have a moderate consumption rate and turnover. They are not as critical as Fast-Moving items, and their stock levels are relatively stable over time.


  • Moderate sales volume.
  • Slower turnover compared to Fast-Moving items.
  • Longer shelf life.

Management Approach:

  • Periodic review and analysis.
  • Adequate inventory control measures.
  • Balanced stock levels to avoid excess.
  1. Non-Moving (N) Category:

Items in the Non-Moving category are characterized by low or no consumption. They have minimal turnover, and their stock levels remain relatively constant over an extended period.


  • Low or no sales volume.
  • Rarely consumed.
  • May be obsolete or have limited demand.

Management Approach:

  • Minimal control efforts.
  • Infrequent monitoring.
  • Consideration for potential obsolescence.

How to Perform FSN Analysis:

  • Determine Consumption Patterns:

Identify the criteria for categorization based on consumption patterns, such as the rate of sales, turnover, or demand frequency.

  • Evaluate Items:

Evaluate each inventory item based on the chosen criteria to determine its classification into the Fast-Moving, Slow-Moving, or Non-Moving category.

  • Assign Categories:

Assign each item to one of the FSN categories based on the evaluation. For example, items with the highest sales volume and turnover may be classified as Fast-Moving, followed by Slow-Moving and Non-Moving items.

  • Implement Different Control Measures:

Apply different inventory control measures and management approaches based on the FSN category. Fast-Moving items may require more frequent and rigorous control compared to Slow-Moving or Non-Moving items.

Benefits of FSN Analysis:

  • Resource Optimization:

Helps optimize resources and efforts by focusing on items with different consumption patterns.

  • Efficient Inventory Management:

Guides more efficient inventory control strategies tailored to the pace of consumption for each item.

  • Cost Optimization:

Supports cost optimization by aligning inventory control measures with the characteristics of each category.

  • Risk Mitigation:

Identifies and mitigates risks associated with slow-moving or non-moving items, such as potential obsolescence.

  • Strategic Stock Planning:

Facilitates strategic stock planning to ensure that the inventory is managed appropriately based on the demand characteristics of different items.
