ABC analysis groups stock items by how much they matter to the business in terms of value and usage. Category C consists of many low-value items that are used but each contributes only a small amount to total value. Because there are so many of these items, they typically make up the majority of items listed in stock records—about three-quarters in common practice. The takeaway is that most items aren’t high-value individually, but their sheer numbers dominate the stock list. This is why Category C is seen as roughly 75% of items in stock records, even though A items drive most of the total value and require tighter controls.

The data to include on the final list of approved capital projects is the complete set that ties the purchase to the right financial and asset-management records from the start. Purchase account keys (charge numbers) ensure the cost posts to the correct general ledger accounts. Asset category provides the classification needed for capitalization, reporting, and policy adherence. Identification codes (when appropriate) give each asset a unique tag or serial number so it can be tracked through acquisition, inventory, maintenance, and disposal. Depreciation expense account number designates where the asset’s depreciation will be recorded, which is essential for ongoing financial reporting and budgeting. Omitting any of these elements would leave gaps: you’d risk misposting costs, misclassifying the asset, losing ability to uniquely identify and track the asset, or misallocating depreciation. Including all four ensures the requisition aligns with proper accounting, asset management, and depreciation planning.

ABC analysis is about prioritizing inventory management based on how much each item contributes to value. It classifies items into three groups—A, B, and C—according to their annual cost impact, with A being the most valuable items, B moderate, and C the lowest. The main idea is to focus control efforts where they count most: tighten stock accuracy, set appropriate stock levels, and schedule more frequent reviews for A items, while applying lighter controls for C items. This targeted approach helps prevent stockouts and excess stock where it would hurt most, and it guides where to invest monitoring and replenishment resources. It isn’t about SAMPLEforecasting, setting price discounts, or evaluating suppliers, which are separate activities.

Cost-Plus-Fixed-Fee means the contractor is reimbursed for allowable costs actually incurred and receives a fixed amount of profit that does not change with the actual costs. The fixed fee is negotiated at the outset and stays the same unless the scope of work changes, in which case the fee may be adjusted. This setup is used when costs are uncertain, shifting cost risk to the buyer while giving the contractor a predictable, fixed profit.

Reorder point is designed to cover the amount you expect to consume during the time it takes to receive a new order. That expected consumption depends on how long you wait (lead time) and how fast you use stock (demand). In practice, you estimate this by using the average lead time, multiplied by your average demand, and then you add safety stock if there’s variability. So the lead time used to compute the ROP is the average lead time because it provides a balanced, central estimate of how long you’ll be without replenishment. Using the maximum lead time would push the ROP higher than necessary and increase carrying costs, while the minimum lead time would risk stockouts. Total lead time isn’t a standard basis for this calculation.
