This is an excerpt from,” Did Sharknado Chew Up All Your Lead Time?”,” found in the August 2013 edition of Retail Value Chain Federation’s monthly newsletter, RVCF Link. To see the article in its entirety: RVCF LINK. It is part of an ongoing 5 part series on Demand Forecasting and Inventory Replenishment.
Lead Time is a large factor in your supply chain performance. Like a shark chewing voraciously, Lead Time variance chews up profits in multiple ways. A shorter than expected lead time causes overstocks with additional carrying costs, theft, and potential damage issues. A longer than expected lead time creates out of stock service issues or additional product and freight costs and devours customer opinions and bottom line profits.
Poor lead time performance also “chums” your supply chain with a barrage of activity; e-mails, phone calls, and impromptu meetings drain organizational energy and productivity while increasing stress levels.
Planning and Analysis: Before You “Enter the Water”
Perception is reality for many companies or where you sit depends on where you stand. If you know lead time issues exist you may believe you know the cause before you assemble the data and analysis to support your conclusions. The opposite is also true; you may believe lead time is not a problem. Some companies believe their short lead times and weekly orders reduce their service risk; often, they don’t even plan or track lead time. Statistically and figuratively companies in this latter group are frequently wrong.
“If you can’t measure it, you can’t improve it” – Peter Drucker
Many companies don’t track or include lead time analysis in their planning process. Instead, they manage lead time issues like a shark sighting – at the last possible moment. Working at the individual PO level, when service issues pop-up like a shark fin on the water surface, it is too late to plan! Studies show that companies, that manage their supply chains holistically, tracking and forecasting each step, are significantly more profitable than their competitors.
There ARE sharks in the water, so plan carefully before entering.
Your supply chain complexity varies by supplier and is location specific. Lead Time Days can also include many other factors: external – transit days, customs, waiting for approvals, and internal – QA inspections, DC to DC transfers, DC processing time, or product processing time to get them ready to use/ship/sell.
We’re Going to Need a Bigger Boat
Poor Lead Time planning can cause additional freight expense or the purchase of excessive quantities of product to meet your business needs. You might use alternate suppliers with higher logistics or product costs or, worse, air freight! Sometimes you are forced to go big or lose big. Lead Time Forecasting across your supply chain with all your suppliers is an important step in reducing these problems and improving profits!
Analyze a Few Problem Vendors
You may want to look at 5 or 10 of your problem suppliers in depth. Start simple; look at the total lead time, not the pieces, that comes later, the goal is to highlight the issues. You can gain further insights by downloading historical information by supplier/location into Excel, generate some averages and graph the variability of allowed lead time versus actual on a PO by PO basis.
To find some examples and easy directions on accomplishing this, download our New Lead Time Forecasting Toolkit. The kit contains: “Guide to Lead Time Analysis,” an Excel ™ workbook w/examples and instructions on analyzing lead time information, a PowerPoint™ presentation “Lead Time Forecasting,” along with several topical articles.
After analyzing a few vendors your results may suggest automating your review using a Lead Time Forecasting Program. A Lead Time Forecasting Program will track all of your supplier, location, product combinations and tell you the correct lead time. Effective solutions will have tools to identify seasonality and other LT influences. Lead Time Forecasting software should also create exception management and allow you to tell the system when long lead times are to be ignored in special cases like placing seasonal orders months ahead of normal operations.
Conclusion: Eliminate Inventory Sharks!!!
A clear vision of Lead Time can help you avoid the sharks, whether they’re based on land, sea, tornadoes, or even alien planets. Like looking out across a vast ocean, many companies have a large number of product locations. Automated Lead Time Forecasting and exception management tools are a key to success; get your supply chain swimming in profits. There are SaaS solutions on the market now that are easily installed and should pay for themselves with an ROI reached in weeks. Eliminate the sharks and you can sail into greater success.
