You may not be making a profitable decision |
| Just sub-contracting manufacture to China is not the answer. In
time, you will find that Chinese companies have reverse-engineered and
redesigned your product and are taking your markets. Not only that but
outsourcing decisions are often flawed because of the traditional works
costing, rather than by accurate value stream costing. |
| Most companies cost their manufacturing incorrectly which makes
outsourcing look profitable when in reality it’s more profitable to retain
manufacture in-house. The article from Brian Maskell below explains: |
| |
| So how should you calculate manufacture cost? |
| - from information by Brian Maskell |
| |
| The problem with current accounting systems |
| Traditional cost and management accounting methods actively work against
this and lead to bad decisions for pricing, margins, make or buy, and other
key issues. They were designed for traditional mass production and job-shop
manufacturing, with measurements such as labour efficiency, machine
utilisation, overhead absorption, and variance analyses. Traditional costing
systems are also wasteful, time-consuming and expensive. They have to be
replaced by methods that actively support low waste operation. |
| |
 |
 |
 |
The important accounting aspects |
| It is the business management system that shows you the financial impact
of changes. It uses performance measurements that motivate and enhance
actions at all levels. These are visual, focused on the value stream,
designed to prompt continuous improvement, support work-teams, and provide
fast effective feedback. |
| Your performance measures become the primary mechanisms of control as
processes are brought under control. You eliminate the need for cost
accounting and inventory control, which are traditionally needed because
processes are out of control. |
| It does not cut costs but turns waste into available capacity. The
financial impact comes as you make strategic decisions on how to use this
capacity, and from the cash flow of reduced inventory. |
| You cost the value stream to eliminate wasteful transactions associated
with traditional cost accounting. In return you get timely understandable
information. |
| You make decisions on the profitability and contribution margin of value
stream: pricing, profitability, make or buy, new product introduction,
product and customer rationalisation. QFD and target costing drives the
business by customer value not cost. You don’t need to know the cost of a
product because all decisions are made by assessing the profitability of the
whole value stream, not of individual products or product families.
Understand the flow of material, information, and cash through the value
stream and the bottlenecks or obstacles to flow. |
| The best way to reduce cost is to increase sales. Use value stream cost
analysis to understand where you expend cost with where you create value for
the customer and where capacity is available. Use Kaizens to align value and
cost through the entire value stream from sales and marketing through
product design to shop floor operations. The team studies the customers
needs and develops action plans to increase customer value and
profitability. These action plans include changes in sales and marketing,
product design changes, operational process improvements, and improved
administration. |

How standard costing can
lead to poor decisions |
| You need accurate and valid financial information when
making important decisions. But you can’t do this by using standard costs.
It is harmful, misleading, and leads to poor decision-making. Use value
stream costing instead. Calculate the costs and profitability of the value
stream as a whole, not for the individual products within the value stream.
Up-to-date information is thereby available on the total costs and
profitability of each value stream. For example: |
| 1. The sales enquiry and the response |
| Company A manufactures hydraulic equipment. The company
received a request for XJ2 valves that they have been manufacturing for many
years. It is small and simple to manufacture. The customer, a large
distributor in East Anglia, wanted to order 3,000 a month, for years into
the future at a target price of £45 per unit. The standard cost for an XJ2
is: |
| |
| Labour time to make an XJ2 |
750 seconds |
| Labour cost per hour |
£ 24.73 |
| Labour cost per unit |
£ 5.15 |
| Overhead rate |
290% |
| Overhead cost |
£ 14.94 |
| Material costs for XJ2 |
£ 22.33 |
| Standard cost XJ2 |
£ 42.42 |
|
| Because the customer was firm on the £45 price, the order
was declined because the profit margin was less than 6%, outside the
company's 15% minimum margin rule with a cost of £42.42. |
| |
 |
 |
 |
2. The inevitable outsourcing proposal |
| But the sales people were not to be deterred in their quest
for a profitable sale. They bought some time from the customer and worked on
finding an alternative source. They found a supplier in the Far East that
could provide the valve at a significantly lower price than the standard
cost: |
| |
| Price to the customer |
£ 45.00 |
| Cost from the Far Eastern supplier |
£ 30.00 |
| Overhead for incoming logistics |
7.5% |
| Total inbound cost |
£ 32.25 |
| Monthly revenue for 3,000 units |
£ 135,000.00 |
| Monthly cost for 3,000 units |
£ 96,750 |
| Monthly profit |
£ 38,250 |
| Profit margin |
28.33% |
|
| The sales people told the customer they were happy to meet
their price and set about ordering 30,000 units to be made and shipped to
the UK from the Far East. |
| |

3. The real costs and the sensible decision |
| But the financial controller was not satisfied with the
outsourcing decision. The plant had been on a lean journey and he had become
a lean leader. He had seen the value stream go from being a long-lead-time,
high WIP, traditional production process to truly lean-focused flow. They
were still a long way from being really lean - but they had made some
progress. The controller reckoned that their value stream could compete with
any company in the world. He also disliked the idea of huge inventories and
complexity that would come from sourcing overseas. It was the opposite of
lean thinking. |
| So he examined the costs using the value stream costing
information reported to the value stream manager each week. Working with the
production management team, he found that the additional volume to support
the 3,000 units-a-month order would need two more people and two more
machines. He worked out how the value stream costs and profitability would
change if they added these additional costs and revenues. |

standard cost, outsourcing, or making in house. |

|
| Clearly the best course of action was to make the product
in-house rather than outsource it. If they made the product in-house, it
would make more money and improve profitability. And the company would save
itself the problems and additional costs of sourcing from a supplier halfway
across the world. |

4. the company’s conclusion |
| After seeing this example, senior management concluded: |
| a. |
Making an important decision using a standard cost is misleading and
wrong. That you can outsource an item for less than the current standard
cost is meaningless. |
| b. |
The team did not abandon the idea of sourcing from overseas, but it was
recognized that these decisions must be made using valid and reliable
financial information. |
| c. |
Valid and reliable financial information comes from up-to-date value
stream direct costs and profitability. These are real numbers, not
artificial accounting concepts. |
| d. |
Few people in the company really understood the standard costing system,
and using it led to serious mistakes. Value stream costing is simple,
readily understandable, and gives information that can be used reliably for
decision-making. |
