Counter-productive actions, decisions, and policies will
have a compounding
they discourage e or
thwart promising ideas, suggestions, approaches, or proposals.
And, if these do get started and then counter-productive actions cause a
failure, it will have a triple compounding
effect by discouraging future attempts!
And the consequences for all of this will be the
forfeiture of all the potential value from then on!
But, one may ask, what if the "nay-sayer"
don’t know any better?
Answer: leaders and
decision-betters have a fiduciary responsibility to "know
And, fortunately, most leaders and decision-makes have access to internal or
external expert consultants and books
and article on Advanced Product Development
and article on Strategies, and
classes that can educate everyone involved.
What is Too Often
Here are 18 common practices that prevent companies from

This is web version of DFM book Section 11.5, "Stop
Counter-Productive Policies." Be sure to
send the DFM book to any source of these policies, with post-it notes on the
appropriate section, noted by the section number below:
The section numbers coincide with section numbers in the
2020 DFM book .
11.5.1) Don’t allow Sales to “take all orders,” sell
any option ever built, and “acceptall customizations” and
pollute operations with low-volume, hard-to-build products that drain resources
away from product development and other improvement programs.
Rationalize Product Lines to eliminate or
outsource high-overhead products that are incompatible with your operations and
supply chains. If hard-to-build products really have
potential, design them into a family in a
product platform. If they do not fit into any product family,
outsource them to a specialist CM or rationalize them away and send all those
problems to your competitors! See DFMbook Section
11.5.2 Don’t Sell Every
Option Ever Sold and Accept All Customizations/*. This
is slow and expensive to do in a mass
building inventory based on
forecasts after ordered parts arrive. If it is valuable to
sell many options, then learn to do Build-to-Order. If it is valuable to
customize products, learn to do
Mass Customization. Solutions: Build
options and modules on-demand with Build-to-Order

is based on Lean Production (Section 4.1) and Standardization (Chapter
5) Customize orders with Mass
summarized in Section 4.3
and taught in Chapter 9 in the 520-page book Build-to-Order
& Mass Customization summarized
in Section D.
11.5. 3) Don’t bite off more than Engineering can chew when planning product
portfolios, which drastically decreases the success rate of all products.
Rationalize Product Lines
to focus on your most profitable products.
This can triple your profits immediately! Just stop selling your
highest-overhead "loser" products. See
DFM book Section 2.3.
Product Portfolio Case Study. The book, Fast Innovation,
(by Michael L. George, et al., 2005,
McGraw-Hill; p. 167) presents a case study which clearly shows how
too many projects diminish the chances of project success.
In the first, year a prominent company tried to
develop 120 products, but resources were spread so thin that no products
were introduced at all! The next year the workload was
reduced to 22 projects and they were able to introduce eight products in 24
to 28 months. In the next year, as they got more focused on only 20 projects,
they were able to launch 14 products in 12 months. Thus
able to successfully launch almost twice as many products in half the time!
The results of focusing product development and
rationalizing away most existing products during a three year period was
that manufacturing productivity tripled, early life failures decreased by 38 times,
customer satisfaction rose from 27% to 90%, revenue increased by 2.4 times, and
operational earnings increased from -6% to +7% !
Don’t “manage” product development with deadline management
(track "progress" at meeting arbitrary deadlines and then putting on the pressure if any deadline is
late) for the illusion of “early progress.” This will be counterproductive if
poorly set deadlines don’t encourage thorough up-front work.
SeeDFM book Section 3.2,
Solution for innovation:
Product development phase scheduling should allow enough up-front
effort, which is (a) when manufacturable innovation
is done and (b) the thorough up-front work
that will cut in half the time to stable production.
Be very sure that your product development process
actually does have a product design phase:
Some, even prominent and expensive "processes" don't, and
skip from the "concept testing" phase to the "prototype testing." phase.
Check your to see
if it has a strong product design phase, or has one at all!
DFM and Concurrent Engineering principles, as described in the
white paper on Concurrent Engineering.
See DFM book Chapters 2 and 3.
Don’t quantify only labor and part cost and then allocate (average) all
other costs (overhead) over all products, even your best "cash cow"
products. To make an impact, tell senior management that their favorite
products are paying a "loser tax" to pay for all the overhead costs on the
measurements to get pricing credit for all the overhead cost reductions,
which can range from 1/2 to 1/0 of the usual costs, as shown in for each
overhead category the page:
See DFM book Chapter 7.
remove cost after the product
is designed, which is so hard to do that it is a waste of resources that
will prevent innovation If this is even attempted, product
development teams will have to devote a very high percentage of product
development resource to make change orders to try to implement DFM retroactively

Reasons Why “Cost Reduction” after Design Doesn’t Work. See
DFM book Chapter 6.
11.5.11) Don’t go for the
low bidder on custom
parts, which means your engineers will have to design the whole part in
isolation, send it out for bids, manage a "bidding war," and then deal with the
consequences of missing out on concurrent engineering with the best vendor.
Pre-select he best vendor as a
will join your team and help you concurrently engineer the part, thus
expanding the team without hiring or transferring any personnel.
This article will show many ways this will actually cost less and get parts
ramped up quicker. See point # 15 on cautions about not to drive away
the best vendors with onerous terms & conditions and outsourced purchasing
and accounts payable. See DFM book Section 2.6.
offshore manufacturing to "save cost,"
which makes it hard to do Concurrent Engineering when there are no manufacturing
people around to be “concurrent” with. In many offshoring situations, people in
engineering and manufacturing are not even working at the same time. So
research can only be done in one time zone, and
launching a product stares with throwing a drawing package "over the ocean,"
which is followed by the Contract Manufacturer "building to print," whether
the drawings are perfect, 100% complete, and completely unambiguous -- or
not, which is the case in almost all offshoring.
Outsourcing, in general, also involves
converting documentation for outsourcing; changing all parts to "local
sources of supply" (which may involve changing hundreds of parts and
inducing hundreds of new variables), getting outsourcers up to speed; dealing with quality and delivery problems, and so forth and so on.
See DFM book Section 4.10.

phases of innovation in concurrent
After DFM training, one large company that has pioneered many of these
needed to launch an initiative called "DFM vs policy" to correct current
counterproductive policies for their first product development team to utilize
these new methodologies.
In his travels, the author of this site,
Dr. David M.
Anderson, has encountered several companies that
wasted two-thirds of
product development resources on the last three bullets (# 6, 7, and 8), which really
puts their future in doubt if that future depends on new product development.
Ironically, these attempts thwart six of the eight Half-Cost strategies,
for reasons presented at the beginning of the
PROBLEMS DEFINING "COST"
MOSTLY AS PARTS
Don't Beat up Suppliers, specifically:
can reduce many costs, reduce NPD resources demands, and reduce the time to
stable production. However, they will not be an option if purchase cost
pressures force teams into the sub-optimal practice of designing in
isolation and then going out for the low bidder. See DFM book Section 2.6.
a) Do not drive your best vendors
away with onerous terms and conditions that stretch out
payments, which doesn't really save money because
the vendors you drove away would have saved
many more costs with better work and do it faster
any saved interest will have to be paid back when
you realize all this and reverse your beat-up-the-vendor policies,
In emergencies, the slow-paying "net 60 day"
customer will get the least attention
Vendor relations is no place "beat up vendors" just
because you can or have the false believe it saves money.
b) Don't outsource Accounts Payable.
which will inevitably stretches out payments even longer and frustrate
vendors with hard to reach offshore people and cumbersome procedure.
Some companies dress these up by calling them "Portals" or :supplier
Network" like they are some kind of benefit. One of these
actually makes vendors buy an access code just to get in.
c) Don't outsource Purchasing
which can thwart standardization, selecting parts for
availability (two major bullets above) , and
concurrent engineering with
both company engineers and vendors.
d) Do not add onerous terms and
conditions to a Non-Disclosure Agreement (and call it a
"Services Agreement") and try to slip in net 60 day or worse
payment terms (or worse) or thwart class customization by claiming
world-wide IP rights to any "work product" done for a class.
Such policies will limit your training to generic training taught by
staff trainers from coprighted taught from published books.
ALERT TO VENDORS AND CONSULTS:
Insist on an NDA without terms and conditions. I f
you get a "services agreement" agreement, you and
your client will have to spend a lot of hours and calendar time to
negotiate away onerour teams and conditions. First suggest
that the client find an Exutive Sponsor first that will
appreciate e will appreciate the following issues:
Assigning IP rights precludes
customization, which results in teaching generic material from a
Stretching out payments will
discourage preparation and rush into "completion" to
get into the "payment queue." This willl
discourage spreading out webinar sessions, which can accomodate more
Ironically, shifting efforts to
contract negotiating and content to generic, presludes the need for
an NDA in the first place
The ultimate irony is that a
class that stresses not "beating up suppliers"
should not beat up the messinger.
11.5.8) Quality compromised.. Pressures to lower part cost
results in cheap parts, which will raise
more their anticipated savings, and that will have the following effect on
NPD: See DFM book Figure 1.2.
Product Development delayed
and costing more. Dealing with
problems caused by cheap parts will:
increase resource demands to deal with quality problems,
See DFM book Section 2.1
introduce many variables, which compromise
functionality, with change orders to make everything work again and fix
new problems caused by all the changes
put pressure on teams to compensate for all the above
cost increases See DFM book Figure 1.2.
delay the time to stable production.
See DFM book Figure 2.1
thwarted by pressures to keep part cost down because most standard parts are
“better” than a proliferation of the minimum spec parts, but the overall
gain from standardization would be so great the material overhead for
standard parts could be discounted to 1/10 of hard-to-get parts (see the
first page of Chapter 4 on Standardization in the
Part availability improvements
also thwarted because more available parts may raise a BOM (Bill Of
Material) entry, but the overall cost savings will be enormous by avoiding
the cost of obsolescence and
supply chain spontaneity which is a key prerequisite to Lean Production.
See Chapter 7 of book
on BTO and Mass Customization.
Off-the-shelf parts discouraged, which can focus
resources on what customers buy products for and lower overall cost, but
this will be discouraged by BOM cost pressures because purchased part cost is
the total cost , whereas BOM cost is only material cost. For instance, wires
are very inexpensive (as they may be “expensed” and not even be listed on
the BOM) but wiring generates enormous labor and quality costs to wire
products "like a house." However, DFM solution to wiring problems and cost
is standard off-the-shelf cables, which will all look like “new expenses”“
on the BOM. See DFM book Section 5.18.
Chapters 9 & 9 ) DFM guidelines thwarted, like “Eliminate Right/Left Parts,” symmetrical
parts, and part consolidation will be discouraged if “extra” processing (to
make right and left parts the same) raises a BOM entry. In one company the
VA team resisted the DFM team’s attempts combine eight different brackets
into one by drilling all the holes for all brackets into one versatile
version because it would add extra hole drilling to most of the versions!
However, if the right and left parts were molded or cast parts, eliminating
the extra mold would save tens of thousands of dollars in tooling costs.
See DFM book Chapters 8 and 9.
Worst possible scenario:
The worst possible “cost reduction” scenario is to *(a) base “cost” primarily on
parts and (b) pressure the design team for ambitious goals, like half the
(parts) cost. That much pressure on parts cost will lead to desperate searches
for the absolute cheapest cost which will:
- Compromise quality, raise quality
costs, worsen reliability, and all the costs to deal with that,
which will lengthen product development time.
- Thwart all real supply chain and lean production
cost improvements such as standardization, designing for part
availability, and off-the-shelf parts, which will be perceived as “raising”
a BOM entry
- Discourage vendor/partnerships if cost pressures on their parts
drive the counterproductive practice of designing in isolation and send out
for the low-bidder
- Discourage DFM improvements that can combine parts and simplify any designs that may raise a
The very last paragraph of the 2020 DFM
book (Section 11.9; Students and Job Seekers Guidance) cautions
engineers, who just learned DFM and are ooking for work, to
avoid companies that do the

the reputation hit from those that leave), and even those who try to

those that write Annual Reports, who should compare their bragging to the
