The list herein may refer to the equipment, materials, and assemblies required for production of the end product.

Step 2: Determine the duration between material order date an expected delivery date for every item in the BOM.

When calculating this duration, you need to consider the supplier’s raw material requisition, processing, and shipping.

Additionally, figure out the work schedule of your organization and for the vendor or sub-contractor too.

Step 3: Find the component in the BOM, which has the greatest lead time.

Ensure you review the lead times for every material in the list as a way of prioritizing one with the greatest lead time.

Step 4: Review the schedule of production to figure out the specific dates and times, which the product quantities shall be available.

You should then adapt the period yielded herein in your organization’s workweek.

This makes it easy to accommodate weekends and holidays in ensuring the production operations are seamless.

Step 5: Now, calculate the administrative lead time. It is primarily the time needed for processing all the necessary paperwork and also completing any requirements of materials purchase.

This involves determining the time required for choosing a supplier, purchase order preparations, purchase authorization, and transmitting the order to the supplier.

Step 6: Here, you’ll calculate the lead time for inter-operations. It is the time required for the task to move from one work center to another during the production process.

Determine and calculate and add all the individual aspects of inter-operations, including the queue time, preparation, post-operations, waiting, and shipping times.

Step 7: Now, you can calculate the overall lead time for the manufacturing process by adding all the different lead time aspects and finding the total.

You’ll then find the total manufacturing lead time of the particular product.

What is the Difference Between Manufacturing Lead Time and Delivery Time?

Manufacturing lead time primarily refers to the commencement time of physical production of the first sub-module, process it, and render it ready for delivery.

In other words, the overall time taken between starting and completing the production process of a particular product awaiting delivery.

On the other hand, delivery time refers to the duration between completed production process and the customer receiving the product.

In simpler words, the delivery time is the period taken during transportation of the commodity from the manufacturer to the customer.

How does Lead Time affect Cost?

Lead time vs cost

Ideally, lead time tends to have a substantive effect on the inventory size of any particular supplier.

Poor management of lead time often leads to stock-outs, which is critical since it reduces fulfillment of customers’ orders as well as product assembly.

In general, underestimating the amount of stock required often tends to be costly to the company in cash flow, turnover, and reputation.

Therefore, appropriate lead time leads to receipt of all the necessary components arriving together.

It thus helps in reducing costs related to shipping and receiving.

Furthermore, improper lead time management can also result in excess inventory, which often tends to put a strain on the company’s budget.

In a nutshell, lead time has a general impact on the company’s income generation and cash flow.

If it is poorly managed, it affects the supplier’s modus operandi, turnover, and reputation among the customers as well.

What is a Lead Time in Procurement?

It refers to the interval between the initiation of procurement action and receipt into the supply module of the production model purchased due to such actions.

In other words, lead time in procurement is simply the period between the first effort initiating products or services until the time of arrival.

Production lead time factors in establishing the need, determining the product and sourcing vendors, negotiation time, ordering and paying.

Additionally, procurement lead time also incorporates the purchasing and its lead time.

In most cases, the purchasing lead time is often measured in months.

But in some instances, it can as well be measured in weeks.

This depends on the scope, size, and quantity of the product being procured.

What is the difference between Manufacturing Lead Time and Shipping Lead Time?

Manufacturing lead time refers to the duration between the start of processing an order and the time the production process is over.

It is basically the time taken between processing the raw materials and finished product.

In some instances, it is always referred to as production lead time.

On the other hand, shipping lead time refers to the duration between dispatch and receiving of a particular shipment.

In some cases, shipping lead time is also known as handling lead time.

Therefore, the shorter the lead time, the higher the customer gratification.

And the essence of this is it builds the reputation of the business and generating more income as well.

It reduces dead stock-When a product takes more time than anticipated to arrive in the warehouse for whatever reason, customers often tend to look for alternatives.

The more it takes to arrive, the more options the clients seek.

And so by the time the goods finally get to your warehouse, they end up as dead stock.

This can be costly since it affects the balance sheet, budget plans, and cash flow of the company.

It enhances flexibility – Reduced lead time enables the company to understand the variations in stock.

In a significant way, it enables you to understand the dynamics of the market and also process the products based on the demand and fluctuations of the market.

How can you Reduce Lead Time?

Generally, lead time is a partial function of your order management system.

The manner you communicate supply of your orders with the vendors and time it takes for fulfillment of the same is also a determinant factor of lead time.

So to reduce the lead time, there is the essence of working from both ends and get buy-in from vendors.

Here are some tips of ways of reducing lead time;

Order in small bits but frequently – Generally, larger orders often take time to be fulfilled and shipped.

The trick is always to produce stock on a more regular and rolling basis.

This helps to attain agility when it comes to meeting market demands.

Additionally, it also makes it easy for the manufacturer to produce and ship the product relatively quickly.

Go for automated inventory management – The likelihood of making a human error when juggling multiple suppliers’ lead time by using basic computer applications is extremely high.

To eliminate the inevitable administrative errors and risks, it would be imperative to automate your inventory management system.

Such a system makes it easy for you to create an order when the stock gets to the reorder point.

Vertical integration – If your company has enough capacity in terms of machinery, space, capital, and human resources, this would be the best idea.

It merely entails sourcing, producing, and assembling internally.

It is easy to integrate suppliers vertically.

In this instance, you’ll be able to meet the demands of retailers within the shortest time possible since all aspects are within the control of your company.

Formulate a clear lead time contract – One of the stipulations of your lead time contract to suppliers should be clear repercussions for any late shipments of your order.

The repercussion could as well stretch to late warnings affecting stock availability, damaged products, price change, and discontinuation, among others.

This will enable you to avert incurring expenses arising from the inconveniences of the supplier.

Share your sales information with your supplier – Ideally, this is more or less of incorporating the supplier as your partner.

The more you share your sales data with the supplier in advance enables them to determine what’s popular.

It also allows the manufacturer to anticipate your needs and get ahead of an order before it is created.

What is EOQ Model in Manufacturing?

It is an abbreviation for Economic Oder Quantity model, which merely refers to the ideal order of quantity a particular company should procure to reduce inventory-related costs.

For instance, EOQ helps in minimizing costs such as order costs, holding costs, and shortage costs, among others.

The essence of EOQ model is to ensure the right quantity of inventory is ordered according to the batch.

This is helpful because it bars a company from frequently ordering from the supplier.

It also helps to ensure there is no excess inventory sitting on the hand.

EOQ

How does EOQ Model Work inLead Time?

Before calculating the EOQ in lead time, it is necessary to determine the setup cost, holding cost, and demand rate.

You also need to consider the reordering timing, order placing cost, storing costs.

In essence, of the company makes orders in smaller quantities but frequently as a way of upholding a specific inventory level, the costs become higher.

What is Lead Time in Logistics?

It refers to the duration from the time a purchase order is created for the supplier until the moment the commodities are delivered to the customer.

Logistics lead time often takes a holistic dimension, given you have to know the other elements of supply times.

For instance, you have to know the production lead time, delivery lead time, and shipping lead time, among other dimensions.

What is the difference between EOQ and POQ Models?

Primarily, EOQ model is the order quantity, which minimizes the total handling and ordering costs.

EOQ tends to take into account inventory holding costs, including shortage, ordering, and storing costs.

POQ model, on the other hand, tends to provide solutions on how-to on the ideal quantity to produce in a particular situation as well as the right time to order specific quantity.

The major difference between these elements revolves around the variance.

EOQ model variance is independent, whereas the variance in POQ model is dependent.

Additionally, the demand rate for EOQ hardly changes, thus making it somewhat predictable.

On the other hand, the demand rate for POQ model is dependent on the production level of the chain.

The other difference here is that naturally, EOQ model’s assumption is the company will produce its quantity at any specific time.

Contrary, the assumption of POQ model is the company will produce every unit only when the company has placed the order to the suppliers.

What is Inventory Management,and why is it Important in your Business?

It refers to the control of inventory and stock items.

It essentially involves supervision of goods flow from manufacturers to the warehouses and point of sale stores through the suppliers and distributors, respectively.

Enhances inventory and planning – Inventory management helps to gauge necessary products, which are in good condition, and arrived-as-described.

It is integral in mitigating stock variance issues and also helps in creating space and cost-effectiveness.

Increases efficiency and productivity – This process helps to eliminate manual input of the stock items hence allowing employees to focus on other fundamental areas of the business.

Enhances customer management and satisfaction – A well-organized inventory management will help to supervise your customers and meet their demands accordingly.

The net effect of this is increased sales turnover and gratification of the customers.

Saves money and time – Keeping track of inventory enables you to save a considerable amount of money and ample time.

This is by determining possible dead stock and finding ways of eliminating the same and also preventing ordering more.

What is Reorder Point?

It refers to the specific level of inventory, which prompts action to stock up the particular inventory.

In simple words, it refers to the threshold a stock should never go below.

It is the least amount possible of a certain commodity, which a company holds in stock, and it’s triggered to re-order should stock fall to the amount.

The essence of the reorder point is to enhance efficiency and convenience by ensuring stock is replaced as soon as it runs out.

This is vital since it helps to avert incidences of stock-outs hence helping in seamless business continuity.

Reorder point is also vital in preventing unnecessary inventory holding costs, which may arise due to placing orders a bit early.

Reorder point

How do you Calculate your Reorder Point?

When calculating the reorder point, it is necessary to use the formula after factoring in all the essential components.

One of these elements is determining the safety stock levels.

Also, in this case, you need to determine the average daily sales and lead time in days.

Once you are preparations are clear, you can use easily calculate the actual reorder point using the following formula;

Reorder Point = (Average Lead time by Average Daily Usage) + Safety stock

Alternatively, you can use a relatively shorter formula to calculate your reorder point.

But this formula does not necessarily factor in the safety stock.

This formula merely requires you to give an estimate of the maximum quantity of materials or products you might require per day.

You’ll then multiply the figure you arrive at by maximum lead time for manufacturing or procuring activities.

In this case, the figure you arrive at will be more or less conservative since you are using estimated maximum usage.

Reorder Point = Maximum Lead Time by Maximum Daily usage

What is Safety Stock, and Why is it Needed?

It refers to the level where surplus stock is often maintained as a way of mitigating risks associated with stock-outs often triggered by uncertainties in demand and supply.

Carrying out safety stock is vital in many ways including the following;

  • Protects against unpredicted discrepancy in supply
  • Prevents stock-outs hence keeping customer service and general satisfaction levels relatively high
  • Averts disruptions revolving around the manufacturing and delivery of goods
  • It helps to compensate for calculation inaccuracies

In a nutshell, it makes it easy for business operations to stay afloat.

Moreover, it also makes it easy to manage and control inventory, thus enhancing efficiency and cost-saving.

How is the Safety Stock Set?

When calculating safety stock, you merely need to have all the necessary information surrounding your purchase and sales order history at hand.

After that, you only need to apply this formula, also referred to as inventory equation to determine the safety stock;

Safety stock = (maximum lead times in days x Maximum daily usage) – (Average daily usage x Average lead time in days)

Using this stock holding formula makes it easy for your business to navigate safety through any possible fluctuations in demand as well as lead time.

Is Safety Stock same to Minimum Stock?

Not necessarily!

Safety stock is basically the inventory, which a company holds in excess of its requirements to cover for the risks associated with lead time.

Ordinarily, there are unforeseen uncertainties, which might arise due to unavoidable or deliberate cases.

In such instances, the safety stock keeps the company going, especially when it comes to continuous supply and delivery to the customers.

Minimum stock level, on the other hand, refers to the level, which indicates the need for reordering based on the strategy and movement of the company.

Ideally, an item in stock should never be allowed to fall below the minimum stock level.

Safety stock

What is the Optimal Safety Stock Level?

There is no definite optimal safety stock level.

Generally, it depends on the service level, and this involves balancing the inventory costs and the stock-out cost.

And this gives you a vital variable for determining the appropriate amount of safety stock.

In other words, the higher the service level, the more the safety stock you need to hold.

What is the Difference Between Cycle Stock and safety stock?

Cycle stock refers to the inventory anticipated to be sold depending on the demand prediction.

In some cases, it is referred to as working stock.

This explains why it is described as a portion of inventory available to meet the specific demand within a particular period.

It is the cycle stock that the customer’s order will be fulfilled from in the inventory.

Safety stock, on the other hand, refers to the stock utilized whenever the actual demand supersedes the sales forecast.

It also comes in handy when perhaps the production output happens to be less than planned.

Ideally, safety stock is merely designed as a cushion for the inventory in case of any unforeseen occurrence in meeting the demand and supply.

What are some of the Best Practices that you can Advise for Inventory Management?

In the supply chain business, inventory management is an integral element in enhancing efficiency and success of the trade.
