The way of the cost reduction

@The cost reduction of the product is the activity to have hung the survival of the industry on. The business needs the development of the product with appeal which is accepted by the market. Then, it doesn't sell in case of not being a selling price with the lowness of 1 dollar than the competition maker. Moreover, it has become a deficit if the profit isn't over even if it sets a low selling price. For the industry, it is every day in the war condition.
The great part with production cost has been approximately fixed at the setting of the design cycle and the manufacturing method of construction of the product and the production quantity. However, the role which does a cost reduction in the factory is big. That is, the mission at the factory is to manufacture a designed product cheaply in the good quality.
Therefore, the way of reducing a cost of production is explained from the experience of the writer below.

The condition to implement the activity of the cost reductionB
‡@ "The production cost item of expense" which composes a cost of production become the accounting system to understand, being monthly every product.
‡A A production cost item of expense every process be particularly grasped like the following table as much as the material process, the manufacture process, the assembler.

The active classification of the cost reduction
A cost reduction is activated, dividing into the following classification after servicing above condition.
‡@ The value analysis activities which changes a design specification
‡A The purchasing cost reduction activity of the bought our parts and the direct material
‡B The manufacturing expense cost reduction activity
@
The item classification of the cost reduction
‡@ The direct cost reduction item (The item which can do a cost reduction when an item is adopted on the same day)
@@₯ The design specification VA item, the standard of quality VA item, the inexpensive material change item and the purchase relation item
‡A The indirect cost reduction item (The item which can not reduce in the production cost in case of implementing the activity of the factor system of the item and result's not coming out)
@@₯ The item of the direct labor productivity improvement₯ The facility overall efficiency improvement item₯ The indirect material change expenses reduction ite₯ The factory management expense (in addition to the fixation expenses, the indirect labor) item₯ The stock, the physical distribution cost reduction item

@In the following. It writes down details about the activity of the cost reduction with manufacturing expenses at the factory.
The reduction of the manufacturing expense
‡@ The cost reduction for the change processing
‡A The cost reduction for the fixation processing
It is divided.
By the past, the productivity improvement activity (the direct labor) was a main activity but under present condition, has a limit cost reduction's.
The match which passed to cost of production item of expense in general is necessary.
That is, it is a direct material cost, change expenses (The consumable stores, the power energy expenses, the repairing expens, the physical distribution costs).@Moreover, the activity which improves the fixation expense, the indirect labor and the factory administrative cost which is made factory management expenses and so on is necessary.Also, the improvement which makes cheap facility mold about the repayment cost of the facilities and the mold, too, and the LCA (the low cost automation) improvement, the disposal of the low load facilities and so on are more necessary.
To improve these, as the big means, a movement and so on are done for the concentration of the factory and the low labor country in the production base. Also, it is the improvement of the administrative cost (the indirect labor, the fixation expenses, the physical distribution costs in the factory) by the improvement of the production system.Then, improvement with substantial productivity and the improvement of the material yield improvement, the consumable stores, the repairing expens are done by all the loss improvement by the TPM activity.

Also, the improvement which makes the one which is made in and the share which is made outside the optimal and so on, too, are one of the meansBy the small improvement means ₯ The concentration of the production line ₯ The integration improvement of the process₯ The improvement of the low additional value work₯ The improvement of the process laying-out₯ The abridgment improvement of the work time₯ The machine cycle time abridgment improvement₯ The LCA (the low cost automation) improvement₯ The abridgment improvement of the down time₯ The improvement of doing manufacture bad and the touching up₯ The improvement of the energy cost
It improves by the above, the linear unit, the process unit
It implements these as "the production cost overhaul activity".
It writes down an active procedure and active contents below..

The production cost overhaul activity

The active step The active contents
1. Cost reduction team's being started and making an active plan EIt composes at the member of each of the design development parts, the manufacturing technique parts, the manufacturing management parts, the quality assurance parts, the manufacturing departments, the purchasing departments to the cost reduction project team formation.
₯ It makes the master plan of the cost reduction activity.(Object product, the outline goal, the active period)
2. The actual state grasping of the cost of production and the production line of the present situation ₯ It investigates the actual cost of the object product in detail (different from the process according to the process) according to the item of expense.
₯ It investigates in the facility overall efficiency of the manufacturing line, and the loss structure (the trouble, the plan, minor key stop Ages, bad in the manufacture, the touching-up), production cycle time, the efficiency, the production system, the number of the manufacturing management points, the stock, production lead time and so on.B
3. The setting of a goal cost of production and the setting of a factor system par ₯ It thinks of "the selling price-the profit=the production cost"Then, it sets a goal with cost reduction percentage from the request of the cost reduction from the customer.
The value which deducted a gross profit (the operating profit + marketing management expenses + development expenses) from the target cost becomes a par with cost of production.
₯ The value which subtracted an actual manufacturing cost from the goal cost of production becomes a cost reduction goal sum.
.It lays out a goal sum to each construction of cost item of expense in these
₯ It sets the par of the production factor system according to the production cost item of expense.
The pars of the facility overall efficiency, the efficiency, the neck process cycle time, the material yield, the fraction defective and the stock such as the ₯ production lead time
‚S4. It extracts an item according to the viewpoint of the cost reduction. ₯ It displays the actual article of the object product, and the similar product, the other company product in the comparison.
₯ It digs up a straight cost reduction item, consulting
₯ It digs up following "the cost of production reduction item digging-up table" according to the process according to the manufacturing process to the reference in the indirect cost reduction item.
₯ It totals the assumption cost reduction sum of each item and it digs up twice of items of the par (50% of implementation yields).
Especially, the design specification item and the item in the aspect of the quality presuppose the thing where the execution yield is bad.
5. It is the execution of the item, saying the programming of the item. ₯ It drafts an item program.It makes an active plan, dividing here with the straight item and the indirect item.
The straight item(Design specification VA, the standard of quality VA, the part sharing, doing the becoming of the material which is inexpensive and the procurement part)
The indirect item
(₯ The improvement of the productivity₯ The improvement of the productivity₯ The cycle time abridgment₯ The improvement of the yield₯ The improvement of the production system₯ The reduction of the stock₯ The efficient-ization of the indirect business₯ The development of the new method of construction₯ Doing the becoming which is made in and so on)
₯ It develops to be short-term, the middle, the activity to do long-range division, OBJ DO in these.
6. The result confirmation of the cost reduction
Then, it puts the brakes.‚UD
₯ It grasps an actual cost regularly according to the item of expense with the confirmation of the implementation item. Then, it confirms the performance suiting of the cost reduction.
₯ Especially, the result of the factor system goes back when the drag isn't sound. It depends and it develops the means which doesn't always relax an activity.
