Get on the Fast Track to Supply Chain Optimization: 3 Best Practices to Streamline Your Inventory Processes

by Rebecca Newell | SAPinsider

April 1, 2010

Rise above the hard realities of today’s global supply chains by improving your operational inventory targets. Uncover three best practices for inventory optimization, and learn how to leverage SAP Enterprise Inventory Optimization by SmartOps to revitalize your supply chain operations.
 

To boost efficiency, run a leaner operation, and drive down supply costs — arguably the top-of-mind goals for today’s manufacturers — many organizations are exploring inventory optimization. Inventory optimization is a technique for improving operational inventory targets to address the hard realities, such as a high number of inventory turns and low customer service levels, of today’s highly complex, ever-evolving global supply chains.

To help put your company on the inventory optimization fast track, I’ll share three best practices for enhancing your supply chain processes. These practices all center on the SAP Enterprise Inventory Optimization application by SmartOps, a solution extension supported by SAP (see Key Term box) that enables manufacturing, distribution, and retail companies to pursue optimal product availability while significantly reducing inventory and working capital. (Toward the end of the article, I’ll also offer a few bonus best practices.)

Best Practice #1: Take a Multi-Stage Approach to Inventory Management

Some companies use single-stage calculations for inventory targets — for example, setting up a single requirement plan without the flexibility or ability to make multiple changes across the enterprise — and then propagate these decisions back into the supply chain. Changes are made one at a time across the entire supply chain — a slow, cumbersome approach that hinders supply chain planners from effectively doing their jobs. This traditional, outdated approach starts with the idealized assumption that planners have complete knowledge of demand distribution, incorrectly accounts for uncertainty, and does not optimize the supply chain. But no planner knows everything, and the models that planners use should reflect this reality.

A multi-stage model is more realistic because it considers all inventory stages simultaneously, accounting for the inventory dependencies across stages at the item-location level and considering various variables and possible scenarios. As a result, inventory is optimized across the entire supply chain.

SAP Enterprise Inventory Optimization offers such a multi-stage modeling approach; the solution is based on advanced algorithms that account for the uncertainty present in supply, demand, and production inputs at a level of granularity that results in reliable, actionable outputs.

By leveraging SAP Enterprise Inventory Optimization, your planners can calculate the relationships among inventories, service levels, capacity, and costs across all stocking locations and stages — and across different types of supply chains, both within organizations and beyond enterprise boundaries, to support supplier and vendor-managed inventory.

Note!

SAP Enterprise Inventory Optimization is flexible enough to accommodate different industries, such as consumer products, manufacturing, and high tech.

Best Practice #2: Look at Supply Planning at the Enterprise Level

Supply planning is a collaborative activity that extends across and beyond enterprise boundaries. But many inventory optimization applications fail to address this expansiveness because they’re neither scalable nor capable of automating planning processes. To be successful, your technology should leverage the multi-stage model at an enterprise level by offering:

  • Visibility across multiple ERP applications and planning systems
  • Support for global inventory planning functionality for understanding inventory liabilities, maintaining service levels, and operating according to supplier and vendor-managed inventory business models

Leveraging data contained within SAP and non-SAP software systems, SAP Enterprise Inventory Optimization senses changes in demand, supply, and network alignment — and responds by providing dynamic, optimal inventory positioning. The offering provides a comprehensive, enterprise-scale process for optimizing, managing, and monitoring inventory stocking levels for finished product and raw material components at all stocking locations, in a multi-tier distribution or manufacturing supply chain.

Best Practice #3: Maintain Ongoing Visibility into Inventory Drivers

With continuous insight into the most granular levels of their supply chains, planners can identify forms and purposes of all inventories in the system and quickly and easily evaluate future planning scenarios.

Using SAP Enterprise Inventory Optimization, planners can explore questions related to potential changes in demand, demand variability, lead times, and cost, and they can target service levels either individually or together in terms of how those changes may affect the required inventory in the supply chain (see Figure 1).

In the end, these capabilities enable planners to optimize inventory levels throughout the organization, helping improve customer service levels while minimizing working capital requirements — resulting in increased efficiency and competitive advantage. The solution continuously incorporates the results of ongoing data analysis, helping identify forecast errors and biases so that planners can correct values and modify assumptions over time. With this flexibility, the solution supports continuous improvement and closes the loop on inventory management.
