In today's competitive
marketplace, many manufacturers have designed their production processes
to handle a wide variety of products, sizes, packaging and volumes to
accommodate the demand from an ever-increasing number of market niches
and needs. This demand has created a more complex production environment
and has put increased pressure on manufacturers to manage production
runs, raw materials, packaging, and changeovers more efficiently. This
complexity, if not managed well, can cause substantial losses in efficiency
and output, resulting in sub-optimal production runs, higher manufacturing
costs, lower asset utilization and lower profits. In order to deal with
this problem, several companies have turned to HMC
to analyze the cost of complexity and provide a solution for managing
it.
Complexity comes from a variety of sources. And while
there is a need for some complexity, much of it is not essential. For
example, some manufacturers don't eliminate old or unneeded SKUs. This
will tend to slow down the production process because of unnecessary
changeovers. They may also be able to combine SKUs in order to generate
longer, more productive runs. A careful analysis of the production process
will often reveal opportunities to combine packaging forms that reduce
changeovers and lower package material costs. A thorough analysis may
also show other areas in the production process where complexity exists,
but is not required.
Analyzing the production process provides some tangible
benefits but often it only scratches the surface in terms of reducing
complexity and generating significant cost savings. HMC
has developed an innovative tool that gives its clients a better
perspective on understanding complexity in the production process. Most
companies today use an allocation technique to assign costs to various
parts of the manufacturing process, also known as Traditional Cost Accounting
(TCA). HMC consultants, however, apply
an Activity Based Costing (ABC) technique, which more accurately reflects
the true cost of producing various products. This is extremely important
because if the costs are not applied correctly, manufacturers will make
production decisions that are not efficient or cost-effective.
At HMC, we use software
tools developed by ABC
Technologies (now SAS), a leader in the field of activity based
costing. These tools enable us to allocate our clients' manufacturing
costs to the activities that produce them, and then analyze more accurately
how those costs flow through their production process. This analytical
technique will produce a more accurate assessment of production costs
and the cost of complexity, and yield a better and more reliable solution
to the complexity problem.
Let us show you an example of what we mean. Let's consider
XYZ Manufacturing, who produced products A & B. They made 100 of
product A and 1000 of Product B, and it took 1 hour of direct labor
to produce product A and 2 hours of direct labor to produce Product
B. At $20 per hour for labor, the direct labor cost for Product A was
$20 and the direct labor cost for Product B was $40. Total overhead
costs were $100,000, and it consumed 2,000 hours of labor.
Under TCA, the overhead allocation costs for Product
A and B are as follows:
|
Product
A Overhead:
($100,000/2,000 hrs. = $50 hr. x 1 hour) = $50 per unit |
Product
B Overhead:
($100,000/2,000 hrs. = $50 hr. x 2 hour) = $100 per unit |
|
If we look at how the costs break down by activity,
we see a different picture:
|
| Activity: |
Total
(Hrs. / Cost) |
Product A
(Hrs. and Cost) |
Product B
(Hrs. and Cost) |
| Set-Up |
100 / $10,000 |
25 / $2,500 |
75 / $7,500 |
| Machining |
800 / $40,000 |
100 / $5,000 |
700 / $35,000 |
| Receiving |
50 / $10,000 |
10 / $2,000 |
40 / $8,000 |
| Packing |
50 / $10,000 |
10 / $2,000 |
40 / $8,000 |
| Engineering |
1000 / $30,000 |
500 / $15,000 |
500 / $15,000 |
| Total |
2000 / $100,000 |
645 / $26,500 |
1355 / $73,500 |
|
Using this ABC methodology, the overhead cost allocation would be as
follows:
|
Product
A Overhead:
$26,500/100 = $265 per unit |
Product
B Overhead:
$73,500/1000 = $73.50 per unit |
|
Now let's compare the total per unit production costs
using each methodology:
|
| Product A Cost: |
TCA
|
ABC |
| Overhead: |
$50.00 |
$265.00 |
| Direct Cost: |
$20.00 |
$20.00 |
| Total: |
$70.00 |
$285.00 |
|
|
| Product B Cost: |
TCA |
ABC |
| Overhead: |
$100.00 |
$73.50 |
| Direct Cost: |
$40.00 |
$40.00 |
| Total: |
$140.00 |
$113.50 |
|
As this chart clearly shows, using activity based costing
produces a significantly different product cost, which will have a substantial
impact on production planning decisions. By allocating the costs based
upon the activity that produced it, we can get a better fix on what
is driving production costs and how to manage them more effectively.
We can also get a more accurate picture of the profitability of each
individual SKU.
What we have also found is that marketing decisions
that increase the manufacturing complexity have typically been based
on the traditional accounting method, which as we've noted above can
seriously misrepresent the true production cost, and ultimately, the
true product profitability. As a result, some companies add SKUs thinking
there is added profitability when in reality, there could be added loss.
Only by using Activity Based Costing can the true profitability of each
SKU be determined. Armed with that knowledge, it is then possible to
make more effective production planning decisions that yield maximum
output at minimum cost in a complex manufacturing environment.
At HMC, we believe in
giving our clients the best tools and methodologies that help them understand
their manufacturing process and environment. Utilizing activity based
costing, we help our customers determine true production costs and product
profitability, which in turn enables them to identify the cost of complexity
and, with our assistance, find ways to reduce it or manage it for maximum
performance.
