The ABC Method was originally developed by Alan Lakein and consists of assigning a priority status of “A,” “B,” or “C” to each of the items of your to-do list or task list. “A” Status Items — “Must Do” High priority, very important, critical items, with close deadlines or high level importance to them.

Example of ABC Analysis Step 1: Multiply the total number of items by the cost of each unit to find the annual usage value. Step 2: After noting all the products of the inventory, it’s time to list them in the descending order based on annual consumption value.

ABC method of inventory control involves a system that controls inventory and is used for materials and throughout the distribution management. It is also known as selective inventory control or SIC. ABC analysis is a method in which inventory is divided into three categories, i.e. A, B, and C in descending value.

ABC/XYZ analysis is a method of grouping planning objects (characteristic value combinations, SKUs) based on their value (revenue or sales volume) and dynamics of consumption or sales. The analysis ranks planning objects according to their value contributions in terms of sales or contribution margin.

How to calculate ABC XYZ inventory analysis

1. Identify the items you want to include in the analysis.
2. Calculate the coefficient of variation for each item e.g (standard deviation / mean) * 100.
3. Sort the items by increasing coefficient of variation and accumulate the figures.
4. Set the boundaries for each category.

The distance formula states that the distance between two points in xyz-space is the square root of the sum of the squares of the differences between corresponding coordinates. That is, given P1 = (x1,y1,z1) and P2 = (x2,y2,z2), the distance between P1 and P2 is given by d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2.

ABC analysis of inventory helps you keep working capital costs low because it identifies which items you should reorder more frequently and which items don’t need to be stocked often – reducing obsolete inventory and optimizing the rate of inventory turnover.

Depending on your needs, it may be necessary to count class B inventory as infrequently as twice per year and class C inventory only once per year. The ABC analysis method saves time and labor counting only the inventory required by the cycle for the class of inventory versus counting all inventory items each cycle.

Features or Characteristics of Activity Based Costing 1. The total cost is divided into two types i.e. fixed cost and variable cost which is necessary to provide quality information to design a suitable cost system in a manufacturing concern. 2. The proper distinction is made between the cost behavior patterns.

ABC analysis is an approach for classifying inventory items based on the items’ consumption values. Consumption value is the total value of an item consumed over a specified time period, for example a year. Their consumption values are lower than A items but higher than C items.

Also referred to as ‘optimum lot size,’ the economic order quantity, or EOQ, is a calculation designed to find the optimal order quantity for businesses to minimize logistics costs, warehousing space, stockouts, and overstock costs. The formula is: EOQ = square root of: [2(setup costs)(demand rate)] / holding costs.

The four types of inventory most commonly used are Raw Materials, Work-In-Progress (WIP), Finished Goods, and Maintenance, Repair, and Overhaul (MRO). When you know the type of inventory you have, you can make better financial decisions for your supply chain.

Manufacturers deal with three types of inventory. They are raw materials (which are waiting to be worked on), work-in-progress (which are being worked on), and finished goods (which are ready for shipping).

Stocktaking (or stock counting) is when you manually check and record all the inventory that your business currently has on hand. It’s a vital part of your inventory control, but will also affect your purchasing, production and sales.

• Periodic Stock Count. Periodic stocktaking can be monthly, quarterly or half-yearly checking of the entire stock over one or two days dependent on the amount of stock.
• Continuous, Perpetual Stock Count.
• Pick Accuracy.
• Stockout Validation.
• Annual Stocktaking.

Stock items are the goods you sell to customers. Inventory includes the products you sell, as well as the materials and equipment needed to make them. Although the definition of stock is concise, there are four main types of inventory: raw materials, work in progress, MRO supplies and finished goods.

Stock-taking or “inventory checking” or “wall-to-wall” is the physical verification of the quantities and condition of items held in an inventory or warehouse. This may be done to provide an audit of existing stock. It is also the source of stock discrepancy information.

Purpose of Stocktaking Stocktaking allows you to keep an accurate track of the physical stock you have, what’s been sold, and what hasn’t. It’s all about comparing the physical stock to what the report says then finding any discrepancies.

An inventory discrepancy happens when the actual on-hand inventory stock is different from the item quantity recorded in an inventory system. Undetected stock discrepancies can result in lost sales, overstocking and poor customer service.

While stocktaking is the physical process of verifying the quantity and quality of the inventory on hand, stock checking is the process that ensures that the stock levels are sufficient to meet the demands of the customers without a delay in the delivery.

Blind Stocktake. With the blind method, quantities are NOT displayed, or given to the counter. Counters simply record whatever number they find, and move on to the next stock. In the case of serialised stock, serial numbers are only shown once they have been scanned.
