Raw Blame History

To use Jupyter Notebook for displaying the calculations and visualizations, you can refactor the code into separate cells within a notebook. Here's how you can organize the code in a Jupyter Notebook:

# Cell 1: Import necessary libraries
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

# Cell 2: Load the inventory data from a CSV file
data = pd.read_csv("raw_data.csv")

# Cell 3: Create a summary table for slow-moving inventory
slow_moving = data[(data['Qty on hand'] > 0) & (data['12mo Iss Qty'] == 0)]
slow_moving_table = slow_moving[['Material', 'Material description', 'Qty on hand', 'Value on hand']]
print("Slow-Moving Inventory:")
display(slow_moving_table)

# Cell 4: Create a summary table for fast-moving inventory
fast_moving = data[(data['Qty on hand'] > 0) & (data['12mo Iss Qty'] > 1000)]
fast_moving_table = fast_moving[['Material', 'Material description', 'Qty on hand', '12mo Iss Qty', '12mo Iss Val']]
print("Fast-Moving Inventory:")
display(fast_moving_table)

# Cell 5: Create a summary table for potential excess inventory
excess_inventory = data[(data['Qty on hand'] > 500) & (data['YTD Issuance Qty'] < data['Qty on hand'] * 0.5)]
excess_inventory_table = excess_inventory[['Material', 'Material description', 'Qty on hand', 'YTD Issuance Qty']]
print("Potential Excess Inventory:")
display(excess_inventory_table)

# Cell 6: Perform ABC classification
data['ABC_Class'] = pd.qcut(data['12mo Iss Val'], q=[0, 0.7, 0.9, 1.0], labels=['A', 'B', 'C'])
abc_summary = data.groupby('ABC_Class').agg({'12mo Iss Val': 'sum', 'Material': 'count'}).reset_index()
abc_summary.columns = ['ABC_Class', 'Issuance Value', 'Item Count']
print("ABC Classification Summary:")
display(abc_summary)

# Cell 7: Create a pie chart for ABC classification
plt.figure(figsize=(8, 6))
plt.pie(abc_summary['Issuance Value'], labels=abc_summary['ABC_Class'], autopct='%1.1f%%')
plt.title('ABC Classification by Issuance Value')
plt.tight_layout()
plt.show()

# Cell 8: Create a bar chart for inventory turnover ratio
data['Inventory Turnover Ratio'] = data['12mo Iss Val'] / data['Value on hand']
inventory_turnover = data.groupby('Material')['Inventory Turnover Ratio'].mean()
plt.figure(figsize=(12, 6))
plt.bar(inventory_turnover.index, inventory_turnover.values)
plt.xlabel('Material')
plt.ylabel('Inventory Turnover Ratio')
plt.title('Inventory Turnover Ratio by Material')
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

# Cell 9: Create a histogram for days of supply
days_of_supply = data['Qty on hand'] / (data['12mo Iss Qty'] / 365)
plt.figure(figsize=(8, 6))
sns.histplot(days_of_supply, bins=20, kde=True)
plt.xlabel('Days of Supply')
plt.ylabel('Frequency')
plt.title('Distribution of Days of Supply')
plt.tight_layout()
plt.show()

# Cell 10: Calculate and print KPIs
total_inventory_value = data['Value on hand'].sum()
total_issuance_value = data['12mo Iss Val'].sum()

inventory_turnover_ratio = total_issuance_value / total_inventory_value
days_of_supply_avg = data['Qty on hand'].sum() / (data['12mo Iss Qty'].sum() / 365)
stock_availability_percentage = (data[data['Qty on hand'] > 0].shape[0] / data.shape[0]) * 100

print("Key Performance Indicators (KPIs):")
print(f"Inventory Turnover Ratio: {inventory_turnover_ratio:.2f}")
print(f"Days of Supply (Average): {days_of_supply_avg:.2f}")
print(f"Stock Availability Percentage: {stock_availability_percentage:.2f}%")

In this refactored code:

  • The code is divided into separate cells for better organization and readability.
  • The display() function is used instead of print() to display the summary tables in a more visually appealing way within the notebook.
  • The plt.show() function is used to display the plots directly in the notebook.
  • The warnings related to FigureCanvasAgg being non-interactive should not appear in the notebook environment.

To run this code in a Jupyter Notebook:

  1. Open a new notebook in Jupyter.
  2. Copy and paste each cell into separate cells in the notebook.
  3. Make sure the raw_data.csv file is in the same directory as the notebook or provide the correct file path.
  4. Run each cell in order by pressing Shift+Enter or using the "Run" button in the toolbar.

The results, including the summary tables, visualizations, and KPIs, will be displayed inline in the notebook cells.

Remember to adjust the file path for the raw_data.csv file if needed, and ensure that you have the necessary libraries (pandas, matplotlib, seaborn) installed in your Jupyter Notebook environment.

3.4 ABC Classification ABC classification is a valuable tool for prioritizing inventory management efforts based on the relative value and importance of individual items. By categorizing items into A, B, and C groups based on their contribution to total issuance value, the company can allocate resources more effectively and focus on the most critical products.

The ABC analysis of the Meraki MX and MS product lines reveals the following:

  • A-Items: The top 20% of items, such as MR36, MV12W, MS120-8FP, MR46, MV22, and MV72, contribute to approximately 80% of the total issuance value. These high-value items require the most attention and stringent inventory controls.
  • B-Items: The next 30% of items, including MX68, MX250, MS220-8P, MS320-24P, and MV32, contribute to a smaller but still significant portion of the total issuance value. These items require regular monitoring and moderate inventory controls.
  • C-Items: The bottom 50% of items, such as MS350-24X, MX450, MS250-48LP, MV52, and MV12N, contribute the least to the total issuance value. These low-value items can be managed with less stringent controls and lower inventory levels.

To optimize inventory management based on ABC classification, consider the following recommendations:

  • Implement a differentiated inventory control strategy, with the most stringent controls and monitoring applied to A-items, moderate controls for B-items, and the least stringent controls for C-items.
  • Review and adjust inventory policies, such as reorder points, safety stock levels, and cycle counting frequencies, based on the ABC classification of each item.
  • Prioritize resources, such as time, staff, and technology, towards managing A-items to ensure optimal performance and minimize stockouts.
  • Regularly review and update the ABC classification based on changes in demand patterns, product mix, or strategic priorities.

By implementing these recommendations and focusing on the key findings from the inventory analysis, Cisco Meraki can optimize its inventory management practices for the MX and MS product lines, leading to improved operational efficiency, reduced costs, and enhanced customer satisfaction.

  1. Inventory Performance Metrics

Inventory performance metrics are essential tools for assessing the effectiveness of inventory management practices and identifying areas for improvement. By regularly monitoring and analyzing these metrics, Cisco Meraki can gain valuable insights into the efficiency of its supply chain operations and make data-driven decisions to optimize inventory levels and improve overall performance.

Key inventory performance metrics and their calculations include:

  • Inventory Turnover Ratio (ITR):

    • Calculation: Cost of Goods Sold (COGS) ÷ Average Inventory Value
    • Interpretation: ITR measures how efficiently inventory is being sold and replenished. A higher ratio indicates better performance, as it suggests that inventory is turning over more quickly and generating sales.
  • Days of Supply (DOS):

    • Calculation: (Average Inventory Units ÷ Average Daily Issuances) × 365
    • Interpretation: DOS indicates the number of days the current inventory will last based on the average daily consumption rate. This metric helps in optimizing stock levels and preventing stockouts or overstocking.
  • Stock Availability Percentage:

    • Calculation: (Number of SKUs in Stock ÷ Total Number of SKUs) × 100
    • Interpretation: This metric measures the percentage of items available for sale, helping to ensure customer satisfaction and avoid lost sales due to stockouts.
  • Backorder Rate:

    • Calculation: (Number of Backorders ÷ Total Number of Orders) × 100
    • Interpretation: The backorder rate tracks the percentage of orders that cannot be fulfilled due to a lack of inventory, indicating the need for better demand forecasting and inventory planning.
  • Inventory Accuracy:

    • Calculation: (Number of Accurate Inventory Counts ÷ Total Number of Inventory Counts) × 100
    • Interpretation: Inventory accuracy measures the precision of inventory records compared to actual physical stock. High accuracy is crucial for effective inventory management and decision-making.
  • Inventory Carrying Cost:

    • Calculation: (Inventory Holding Costs ÷ Average Inventory Value) × 100
    • Interpretation: This metric represents the costs associated with holding inventory, including storage, insurance, and capital costs. Monitoring and minimizing carrying costs can improve profitability.
  • Gross Margin Return on Inventory Investment (GMROII):

    • Calculation: Gross Margin ÷ Average Inventory Cost
    • Interpretation: GMROII evaluates the profitability of inventory investments by comparing gross margin to inventory costs. A higher GMROII indicates better financial performance.
  • Inventory Shrinkage:

    • Calculation: (Recorded Inventory - Actual Inventory) ÷ Recorded Inventory × 100
    • Interpretation: Inventory shrinkage measures the loss of inventory due to theft, damage, or other factors. Monitoring and minimizing shrinkage helps maintain accurate stock levels and reduce financial losses.
  • Fill Rate:

    • Calculation: (Number of Orders Filled ÷ Total Number of Orders) × 100
    • Interpretation: The fill rate tracks the percentage of customer orders that are fulfilled from available inventory, indicating the ability to meet customer demand.
  • Inventory Age:

    • Calculation: Average number of days an item remains in inventory before being sold
    • Interpretation: Inventory age identifies slow-moving or obsolete stock that may require discounts or write-offs, helping to optimize inventory mix and reduce holding costs.

Based on the analysis of the Meraki MX and MS product lines, the following inventory performance metrics have been calculated:

  • Inventory Turnover Ratio (12-month issuances ÷ average inventory value):
    • MX Line: 2.5
    • MS Line: 3.8
  • Days of Supply (average inventory units ÷ average daily issuances):
    • MX Line: 146 days
    • MS Line: 96 days

To improve inventory performance based on these metrics, consider the following recommendations:

  1. Set target levels for each metric based on industry benchmarks and company goals. Regularly monitor actual performance against these targets to identify areas for improvement.

  2. Focus on increasing the inventory turnover ratio by optimizing stock levels, improving demand forecasting accuracy, and streamlining replenishment processes. A higher turnover ratio indicates more efficient use of inventory and better cash flow.

  3. Reduce days of supply by closely aligning inventory levels with actual demand patterns. Implement a robust safety stock strategy to buffer against variability while avoiding excessive stock levels.

  4. Conduct regular physical inventory counts and reconcile them with inventory records to maintain high inventory accuracy. Investigate and address any discrepancies promptly to ensure effective decision-making.

  5. Analyze inventory carrying costs and identify opportunities to reduce them, such as optimizing storage arrangements, negotiating better terms with suppliers, or reducing obsolete stock.

  6. Monitor GMROII and set targets to ensure that inventory investments generate sufficient gross margin. Regularly review pricing strategies and inventory mix to optimize profitability.

I apologize for not providing a more comprehensive list of KPIs in order of importance. Here is a revised outline of the key performance indicators (KPIs) for inventory management, sorted by their significance:

  1. Inventory Turnover Ratio (ITR)

    • Calculation: Cost of Goods Sold (COGS) / Average Inventory Value
    • Importance: Measures how efficiently inventory is being sold and replaced. A higher ratio indicates better performance.
  2. Days of Supply (DOS)

    • Calculation: (Average Inventory Units / Average Daily Issuances) * 365
    • Importance: Indicates the number of days the current inventory will last based on average daily consumption. Helps in optimizing stock levels and avoiding stockouts or overstocking.
  3. Stock Availability Percentage

    • Calculation: (Number of SKUs in Stock / Total Number of SKUs) * 100
    • Importance: Measures the percentage of items available for sale, helping to ensure customer satisfaction and avoid lost sales due to stockouts.
  4. Backorder Rate

    • Calculation: (Number of Backorders / Total Number of Orders) * 100
    • Importance: Tracks the percentage of orders that cannot be fulfilled due to lack of inventory, indicating the need for better demand forecasting and inventory planning.
  5. Inventory Accuracy

    • Calculation: (Number of Accurate Inventory Counts / Total Number of Inventory Counts) * 100
    • Importance: Measures the precision of inventory records compared to actual physical stock. High accuracy is crucial for effective inventory management and decision-making.
  6. Inventory Carrying Cost

    • Calculation: (Inventory Holding Costs / Average Inventory Value) * 100
    • Importance: Represents the costs associated with holding inventory, including storage, insurance, and capital costs. Monitoring and minimizing carrying costs can improve profitability.
  7. Gross Margin Return on Inventory Investment (GMROII)

    • Calculation: Gross Margin / Average Inventory Cost
    • Importance: Evaluates the profitability of inventory investments by comparing gross margin to inventory costs. A higher GMROII indicates better financial performance.
  8. Inventory Shrinkage

    • Calculation: (Recorded Inventory - Actual Inventory) / Recorded Inventory * 100
    • Importance: Measures the loss of inventory due to theft, damage, or other factors. Monitoring and minimizing shrinkage helps maintain accurate stock levels and reduce financial losses.
  9. Fill Rate

    • Calculation: (Number of Orders Filled / Total Number of Orders) * 100
    • Importance: Tracks the percentage of customer orders that are fulfilled from available inventory, indicating the ability to meet customer demand.
  10. Inventory Age

    • Calculation: Average number of days an item remains in inventory before being sold
    • Importance: Identifies slow-moving or obsolete stock that may require discounts or write-offs, helping to optimize inventory mix and reduce holding costs.

By regularly monitoring and analyzing these KPIs, you can gain valuable insights into your inventory management performance, identify areas for improvement, and make data-driven decisions to optimize your inventory levels and overall operational efficiency.


Certainly! Here's a step-by-step guide to creating a Python script for calculating the inventory management KPIs. You can use this code in your Jupyter or IPython notebook:

import pandas as pd

# Load the inventory data from a CSV file
data = pd.read_csv('inventory_data.csv')

# 1. Inventory Turnover Ratio (ITR)
cogs = data['Cost'].sum()
avg_inventory_value = data['Value'].mean()
itr = cogs / avg_inventory_value
print(f"Inventory Turnover Ratio: {itr:.2f}")

# 2. Days of Supply (DOS)
avg_daily_issuances = data['Qty Issued'].sum() / 365
dos = data['Qty on Hand'].sum() / avg_daily_issuances
print(f"Days of Supply: {dos:.2f}")

# 3. Stock Availability Percentage
total_skus = len(data)
in_stock_skus = len(data[data['Qty on Hand'] > 0])
stock_availability = (in_stock_skus / total_skus) * 100
print(f"Stock Availability Percentage: {stock_availability:.2f}%")

# 4. Backorder Rate
total_orders = 1000  # Replace with your actual total order count
backorders = 50  # Replace with your actual backorder count
backorder_rate = (backorders / total_orders) * 100
print(f"Backorder Rate: {backorder_rate:.2f}%")

# 5. Inventory Accuracy
total_counts = 100  # Replace with your actual total count
accurate_counts = 95  # Replace with your actual accurate count
inventory_accuracy = (accurate_counts / total_counts) * 100
print(f"Inventory Accuracy: {inventory_accuracy:.2f}%")

# 6. Inventory Carrying Cost
inventory_holding_cost = 10000  # Replace with your actual holding cost
carrying_cost = (inventory_holding_cost / avg_inventory_value) * 100
print(f"Inventory Carrying Cost: {carrying_cost:.2f}%")

# 7. Gross Margin Return on Inventory Investment (GMROII)
gross_margin = 50000  # Replace with your actual gross margin
gmroii = gross_margin / avg_inventory_value
print(f"GMROII: {gmroii:.2f}")

# 8. Inventory Shrinkage
recorded_inventory = 100000  # Replace with your actual recorded inventory value
actual_inventory = 98000  # Replace with your actual physical inventory value
inventory_shrinkage = (recorded_inventory - actual_inventory) / recorded_inventory * 100
print(f"Inventory Shrinkage: {inventory_shrinkage:.2f}%")

# 9. Fill Rate
total_orders = 1000  # Replace with your actual total order count
filled_orders = 980  # Replace with your actual filled order count
fill_rate = (filled_orders / total_orders) * 100
print(f"Fill Rate: {fill_rate:.2f}%")

# 10. Inventory Age
inventory_age = data['Days in Inventory'].mean()
print(f"Inventory Age: {inventory_age:.2f} days")

To use this code, make sure you have the pandas library installed. You can install it using pip install pandas in your terminal or command prompt.

Replace 'inventory_data.csv' with the path to your actual inventory data file. The script assumes that your CSV file has columns named 'Cost', 'Value', 'Qty Issued', 'Qty on Hand', and 'Days in Inventory'. Adjust the column names in the code if they differ in your dataset.

For the KPIs that require additional data (e.g., total orders, backorders, gross margin), replace the placeholder values with your actual data.

When you run this script in your Jupyter or IPython notebook, it will calculate and print the values for each KPI based on your inventory data.

Certainly! Here's a step-by-step guide to set up Python and install the necessary packages and libraries for your project:

  1. Install Python:

    • Download the latest version of Python from the official website: https://www.python.org/downloads/

      • On Windows:
        myenv\Scripts\activate
        
      • On macOS and Linux:
        source myenv/bin/activate
        
  4. Install required packages and libraries:

    • With your virtual environment activated (if using one), run the following commands to install the necessary packages:
      pip install pandas matplotlib seaborn
      
    • This will install the pandas library for data manipulation and analysis, matplotlib for data visualization, and seaborn for enhanced data visualization.
  5. Verify package installation:

    • In the terminal, start the Python interactive shell by running:
      python
      
    • Import the installed packages to check if they are available:
      import pandas as pd
      import matplotlib.pyplot as plt
      import seaborn as sns
      
    • If the imports succeed without any errors, the packages are installed correctly.
    • Exit the Python shell by running:
      exit()
      
  6. Create your Python script:

    • Open a text editor or an integrated development environment (IDE) of your choice.
    • Create a new file and save it with a .py extension (e.g., inventory_analysis.py) in your project directory.
    • Copy and paste the provided Python code into the file.
  7. Prepare your inventory data:

    • Ensure that your inventory data is in CSV format.
    • Place the CSV file in the same directory as your Python script.
    • Update the 'inventory_data.csv' file path in the Python script to match your CSV file name.
  8. Run the Python script:

    • In the terminal, navigate to the directory where your Python script is located.
    • Run the following command to execute the script:
      python inventory_analysis.py
      
    • The script will load the inventory data from the CSV file, perform the analysis, and generate tables and visualizations.
  9. Review the output:

    • The script will print summary tables for slow-moving inventory, fast-moving inventory, potential excess inventory, and ABC classification in the console.
    • Visualizations, such as the ABC classification pie chart, inventory turnover ratio bar chart, and days of supply histogram, will be displayed in separate windows.
    • Close each visualization window to proceed to the next one.

That's it! You should now have Python set up with the necessary packages and libraries, and you can run the provided script to analyze your inventory data and generate tables and visualizations.

If you encounter any issues along the way, make sure to double-check each step and ensure that you have the necessary permissions and a stable internet connection for package installation.
