Lead times are probably the biggest contributing factor that influences the performance of your supply chain.

Understanding lead time is important for every type of business.

An Examole of What Happens if You don’t Understand Lead Time

Let’s say you’re a retailer who orders a product that has a lead time of one month.

Two weeks after placing the order, your research shows that interest in the product has vanished.

Now when that product finally arrives in two weeks, it runs the risk of becoming dead stock.

And that’s just a simple process of ordering something, for manufacturers they have to consider:

• Material lead time;
• Production lead times; and
• Cumulative lead times.

If there’s one hiccup with any of these lead times, your overall manufacturing lead time is affected, which means customers’ orders will be delayed causing them to become unhappy and drive away sales.

Reducing your manufacturing lead times by as much as you possibly can will help you avoid creating bottlenecks as you wait for deliveries or resolve customer wait times as quick as possible.

But, how exactly do you go about reducing your manufacturing lead time?

How to Reduce Manufacturing Lead Time

So, you now know how to calculate your lead time, but now comes the hard part, implement processes to reduce your lead time.

Well, this is where you can begin to dissect things and work out how to reduce lead time in your master production schedule because remember, the lower your manufacturing lead time, the less your customers have to wait for their orders.

The first is to make sure you are taking your inventory management seriously enough. But how does this help?

For one, it decreases your preprocessing time by making your purchasing a more efficient process. You don’t have to spend as much time planning your purchases because you already know if anything is missing.

The other effect it has is to make sure that you always have the right set of materials in stock. This means no waiting around with your hands in pockets for a delivery of raw materials before anything gets done.

Here are three quick tips that can get you started on the journey of reducing manufacturing lead time.

Shorten Lead Time and Optimize Inventory Management

Tip #1 – Set Reorder Points and Safety Stock

Getting into the habit of setting reorder points and keeping safety stock is going to be a lifesaver later down the line and help you implement lean inventory. A reorder point is a technique of identifying what is the optimal level of inventory to keep stocked until you order or manufacture more items.

Safety stock, on the other hand, is usually associated with make to stock businesses, but it doesn’t hurt to practice this, even if you use just-in-time inventory. Your safety stock is a buffer, so you can still fulfill orders while waiting on deliveries or production to finish.

Tip #2 – Complete Tasks in Parallel

It’s easy to become laser-focused on a product’s workflow.

From point A, it moves to point B, point C, and so on. But it might be that one of the stages of production can be started and finished in tandem with other processes?

By figuring out what tasks can be completed at the same time you’ll be saving 100’s of hours in the long run.

Tip #3 – Automate Inventory Management

Tracking supplier lead times and your own manufacturing lead times manually is an inevitable disaster waiting to happen.

According to studies, in every 300 characters, there’s at least one mistake. This might seem a non-issue to you, but over time these errors quickly add up and increase your lead times and bleed capital from your business.

Automating your inventory management will allow you to monitor inventory movements in real-time, and identify the inventory turnover ratio of your products.

But, be sure that you’re reducing lead time, and not cutting corners…

There is a difference.

Maintain Product Quality When Reducing Manufacturing Lead Time

When decreasing lead time these two factors should always be in the balance:

• Product quality; and
• Customer satisfaction.

You can spend all the time in the world scheduling to absolute perfection and managing your inventory valuation methods. There are always factors that are out of your control because we all know that manufacturing rarely goes exactly to plan.

Margins of error need to be accounted for, and more than that you have to stay in touch with the floor level operations.

Often it occurs that workstations decrease their lead times at the expense of product quality.

It may be that you can have two of your team members working simultaneously on tasks.

But did you consider that beforehand they were using each other’s free hands for quality assurance when working alternately, and now they can’t do that?

There are so many minute details that can be missed when reducing lead times, that often corners can be cut even without any malice intended.

The worst-case scenario here is that there are knock-on effects on your customer’s satisfaction.

It’s important that you make changes gradually to processes so that you can keep track of your product quality and customer satisfaction.

You always need to consider the balance struck between lead times and your final product.

There are dangers to fixating on one angle because you might end up with tunnel vision. And then your hard work sadly just goes to waste.

So, with changes to be made but the steps needing to be incremental, what is the best way of tracking your progress when reducing your manufacturing lead time?
