Inventory Management in Manufacturing

Description

* The Course has subtitles in English, Afrikaan,  Italian, Simplified Chinese, Spanish and Japanese

In a Manufacturing Industry, you will be using multiple types of materials to make and sell your Products. Each type of material according to it's use, will have to be planned for fulfillment, storage, usage in Manufacturing and selling the main products. Various types of material such as Raw material, Finished material, sub-assembly or semi-finished material and MRO etc are to be handled in different ways in terms of planning, storing, valuations and managing their inventories.

Hence planning of materials for making and selling product and planning of the product (finished items) themselves needed multiple levels of strategy to ensure you keep the customer satisfied and at the same time, keep your financial parameters in control.

You hence needed to understand the functions of multiple types of inventories to determine the kind of controls you want to apply. Understanding on various types of materials helps in that aspect. In addition, the special classifications such as ABC Analysis can consolidate the kind of material that need maximum attention and those that can have relatively loose controls. In other words ABC classification helps you determine the level of Inventory Policies and controls to apply on specific group of Items

The planning of the materials was quite preliminary before 1960's. Those days, the planning was just reactive on the basis of inventory stock levels. the review of stocks was also done only on basis of stock level of each item without any consideration on dependencies among the items handled in your organization. For example, you plan laminations, Wood and bolts at individual levels without acknowledging that all of them together may be required to make a piece of furniture such as Table, Chair etc. The assumption made in these reactive inventory planning methods were not at all close to real business scenarios. Hence planning used to fail many times. Or to avoid the risks you might be purchasing huge quantities of materials. in both cases the results will lead to financial losses in terms of loss of customers or loss of investment due to huge inventory costs.

The evolution planning to more and more matured levels was from the basic order point system to Time phased order point (which looked at timing of order in addition to tracking stock levels) and Material requirement planning - MRP (which in addition to TPOP way of working, added the "Kit based planning". There are a few more enhancements to the planning that included Constraint based planning . You also have another concept of reaching NO INVENTORY state, in what is called Just in Time - JIT environment  by removing all inefficiencies causing the need to hold inventories.

The course will cover the above aspects in a structured form.

You start with Inventory definition and appreciate the need to perform inventory management.

After that you will run through a few popular Inventory types and how they are handled in relation to manufacturing environment.

You will than go through Inventory classification based on which the level of control to be applied on each class of the inventory is determined.

The context of how planning is evolved over a period of time is briefed after covering the inventory aspects in above sets of lessons

A few quantity or stock based order review methods (such as Re-Order Point, Period Order Quantity , Two Bin System etc) are introduced.

This set of lessons is followed by a few Demand based order review methods which included TPOP - Time phased Order point method and most comprehensive planning method - MRP as well.

Popular Lot sizing techniques are explained with relevant illustrations for most of the methods. While explaining the Selection factors for each techniques, some influencing factors  are briefed.

You may want to know how Safety Stock is planned and calculated to handle unforeseen demand. One section Safety stock calculations will provide insight on demand analysis, demand variations and safety stock calculations.

Section on Inventory Valuation has lessons explaining the post popular accounting techniques for Inventory, such as LIFO, FIFO, Standard Costing, Average Costing and Process costing etc. You will go through example valuations for most of these methods.

With understanding that all your planning and calculations need accuracy of inputs such as Inventory data, the section Inventory accuracy provides fair understanding on Inventory accuracy and important Inventory counting and correction methods such as Physical or Annual Inventory, Cycle Counting and combinations. For each method, sample counting techniques, report analysis are explained through an example scenario.

Finally you need to know how is your Inventory Management Performance. Lessons in this section explain the performance metrics that directly or indirectly reflect the Inventory Management performance. The metrics such as Inventory turnover ratio provide indirect measure of sales and delivery performance, whereas other metrics such as Customer service directly reflect the performance of sales and Manufacturing. You will go through many examples and calculations in this section as well.

The Course is associated with a Practice KIT of 75 Questions and answers along with explanation for each of the Questions in the Kit. These explanations themselves act as additional notes for the students benefit when they prepare for Certifications in space of  Production and Inventory Management and Supply Chain Practice etc.
