Why have inventories?
There is much talk now about the need for low inventories in the system and the benefits that implies for the system. In a way it bothers me almost isolated approach the issue of stocks and perhaps the fact that somehow lost a bit the concept that inventories are in the Theory of Constraints, especially when it comes to low or high inventories.
Theory of Constraints for the essential is the cushion that protects the system against possible disruptions. A cushion can be long or stock depending on the protection we seek to establish in the system. So, to protect the exploitation of critical resources (physical restraints or internal lever pressing points), we define shocks while helping to establish the line (plan of releasing work orders or production materials) and affect in-process inventory. That is, the shock of time results in inventory of work in process, although the level of these stocks is consistent time on the shock and not a specific amount of materials or products.
Additionally, in a system we usually have two stock buffers to protect the system. Commodity cushion that protects us against disturbances in the procurement processes that require, and the shock of finished products that protect us against variations and disturbances that may exist in the market and distribution system. The management of these buffers is critical to meet the replenishment.
Then, the inventory is only a buffer is necessary only when the client is less tolerance of our time in advance, or in the case of inputs, when the time before the supplier is not so quick to supply us our needs within our own tolerance. Thus, we can not talk about low or high levels of inventories and even venture to compare this with the traditional in concept inventories. While we keep talking about inventories and buffers not, keep current confusion between traditional approaches and management constraints.
Shock Management, Accounting and Investment
I think the emphasis in this concept is critical to the TOC or management restrictions. It is therefore the ideal environment in the TOC is a make-orders and improvement efforts should always try to make as much as you can the traditional production environment to a production against orders. The shocks of time management and stock is the essential tool for this. This concept is essential to the solution of production, and distribution solution for sales and marketing solution under the constraint management.
addition, the emphasis in the TOC is the conversion of inventory sales, but that revolves around three key metrics of throughput, investment and operating costs. The investment concept is elementary in this case, since it is all that we acquired with the intent to sell and somehow cleverly split the investment in fixed assets we buy and then sell it. This ingenious concept is a difficult concept to digest from the traditional perspective, and especially if we have clarity of the concept of buffers. Clear that fixed assets are investments and accounting for TOC evaluation of future investments in capacity are clearly only when we can evaluate the real impact on the holistic system, taking into account the existing restrictions and possible future restrictions. Even considering that investments in fixed assets is part of there is one that deserves much attention from the merits involved.
Accounting in the Theory of Constraints clearly differentiates the buffer stocks of raw materials (which we bought with the intention of selling) of the dampers in process and finished products. Traditional accounting is not conducive to facilitate the detachment necessary for the management constraints are enhanced in a company and is one of the most restrictive normally found to initiate change under the management of constraints.
In an enterprise system we know we have stocks of both raw materials and products in process and finished products - mainly as a result of shocks and not a traditional budget outline. Also, the throughput speed is a concept in the generation of this contribution and also the emphasis of the concept of truly variable costs, without accounting devices such as the traditional cost accounting - can not continue talking about throughput and contribution as if they were synonyms.
Equating inventory investment, the TOC only intended to infer that is what we bought with the intention of selling and purchasing cost is the only thing we know with sufficient certainty - so we deal with stocks of raw material cost as an investment until you actually receive the income from the sale value . The real life of inventory in the system, from raw material to finished product depends only on the speed with which we move the incoming raw material to the actual sale of the same processing into products / services of added value.
