3Step 1 Create a Design Brief
- The design brief topics, provided here as
examples, offer a systematic approach for a DfE
project of some magnitude. However, the topics
are suggestions only. Use those that make the
best sense for your company and project.
4- A design brief can include
- General analysis of the existing product, as in
traditional design briefs. - Reasons for the selection of the specific product
or component for DfE. - Particular DfE strategies chosen as a focus.
- A statement about the project team's latitude,
i.e., how radically the existing product concept
can be changed. - Indication of the environmental and financial
objectives. - How the project is to be managed.
- How the results will be documented and measured.
- Final composition of the project team, plus any
outside experts, and a description of members'
responsibilities. - Project plan and time frames.
- Project budget and its allocation to subsequent
activities.
5Step 2 Analyze the Product's Environmental
Profile A good understanding of the product's
main environmental impacts during its total life
cycle is an essential first step. Your project
team should decide the exact scope of the
environmental profile by considering, not only
the physical product, but also the whole system
required for the product's proper functioning.
6Qualitative analysis versus quantitative
analysis The project team needs to decide how to
analyze the environmental profile of the existing
product. Several methods, qualitative and
quantitative, are available to do this. This
section describes two qualitative tools the MET
Matrix and the DfE Checklist. For best results,
they should be used in conjunction with each
other. While a qualitative analysis does not
involve data, it is not as detailed as a
quantitative approach. Often, just establishing
the environmental impact of a component or
sub-assembly of the product will
suffice. However, if your team plans to deviate
from the qualitative approach recommended in this
section, you may find advantages to allocating
more time and money on an extensive quantitative
life cycle analysis. For example, the project
team may undertake a quantitative approach when
they have minimal understanding of the
environmental impact of the product. When the DfE
project is over, you will gain valuable
information by comparing the environmental
profile of the improved product to that of the
former product. This data may also be important
for companies who have an existing Environmental
Management System in place, and for companies
upstream or downstream in the supply chain. If
your project team decides to analyze the
environmental product profile in greater detail,
it can make use of computer tools developed for
this purpose, e.g., Life-Cycle Assessment
software. The team may also consider hiring a
consultant experienced in Life-Cycle
Analysis. Another solution is to combine
qualitative and quantitative approaches if this
would better meet your company's needs. In this
case, the MET Matrix and DfE Checklist, discussed
below, can be combined with a quantitative
life-cycle assessment.
7The MET Matrix (Material cycle, Energy use and
Toxic emissions) The MET Matrix is a qualitative
tool for performing a functional analysis of a
product's environmental profile. Its vertical
axis is used for stages of the product life
cycle, while the horizontal axis allows for input
on the environmental effects per life-cycle
stage. The environmental effects are grouped into
three main areas 1. Material cycle
(input/output)2. Energy use (input/output)3.
Toxic emissions (output) The product life cycle
is divided into five stages 1. Production and
supply of materials and components.2. In-house
production.3. Distribution--this is presented
only once, although it represents all
distribution stages in the product life.4. Use,
including operation and servicing.5. End-of-life
system, including recovery and disposal.
8To use the MET Matrix, the project team should
undertake three activities a) Define the product
system boundaries Your team defines what exactly
belongs to the product system being studied
versus what does not. It should focus not only on
the physical product, but also the auxiliary
products/consumables necessary during the
product's total life span. b) Perform a needs
analysis After defining the product, the team
must address two central questions 1) how does
the product fulfil the needs it is meant to
satisfy? and 2) can a product system be developed
that fulfils the same needs in a radically more
effective and efficient way? For a more detailed
description of the needs analysis, see the
discussion on "Needs Analysis" in the DfE
Checklist later in this section. c) Perform a
functional product analysis The team should then
set up a MET Matrix using the MET Matrix
Worksheet in order to focus on the physical
product and its separate components
9- The functional analysis begins by describing
- The product's functionality.
- Listing weak and strong parts/components.
- Measuring or projecting the product's life span.
- The product's energy consumption.
10- Functional analysis should
- Disassemble the product
- Measure the weights of the assemblies and
components. - List the type and amount of materials and
components. - Identify connections between materials and
components.
11- To perform the functional product analysis
systematically, the team should - Fill out the matrix for the main product,
ensuring that auxiliary products/consumables are
taken into account. - Study a specific sub-assembly or component in a
separate matrix if this item itself turns out to
be a serious environmental problem. - Examine all the cells of the matrix and highlight
those where there are environmental bottlenecks. - If possible, use measured data in the matrix to
prevent working with vague statements
12- Material Cycle This column is for information on
environmental problems concerning the
input/output of materials. It should include data
about - Non-renewable materials.
- Materials that create emissions during
production, e.g., copper, lead and zinc. - Incompatible materials.
- Inefficient use or lack of re-use of
materials/components in all five stages of the
product life cycle.
13- Energy Use This column is for information
regarding energy consumption. Your team should - List inputs of materials with an extremely
high-energy content in the first cell. - Include energy consumption for the product itself
as well as for transport, operating, maintenance
and recovery. - Include exhaust gases produced as a result of
energy use.
14Toxic Emissions This last column is for the
identification of toxic emissions to land, water
and air.
15- The DfE Checklist
- DfE Checklist Worksheet provides support for a
qualitative environmental analysis by - Listing all the relevant questions that need to
be asked when establishing environmental impacts
during the product's life cycle. - Indicating improvement options for areas where
environmental problems are identified. - The Checklist starts with a needs analysis--a
series of questions concerning the functioning of
the product as a whole. This section of the
Checklist answers the overarching question to
what extent does the product fulfil its main and
auxiliary functions? This answer is necessary
before the team can focus on the environmental
impacts in each life-cycle stage. - The set of questions regarding the functioning of
the product as a whole is followed by five sets
of questions that correspond to the five stages
of the product's life cycle.
16Step 3 Analyze Internal/External Drivers
- Motivation to implement DfE can come from two
different directions. - Within the company itself--internal drivers.
- From the immediate surroundings--external
drivers.
17Internal drivers Your team should fill in the
Internal Drivers for DfE Worksheet.
18Internal drivers
19Trade/industrial organizations. These
organizations often encourage member companies to
take action on environmental improvement and/or
may impose penalties on companies that do not
take required action. As well, standardization
organizations are expanding all existing norms
and standards to include environmental issues.
The ISO 14 000 series will become the
international standard for certifying
environmental management systems. It is expected
that product-related aspects, such as the
obligation to collect and publish environmental
data, will be incorporated in this standard.
20Internal drivers
- Need for increased product quality. A high level
of environmental quality will raise product
quality in terms of functionality, reliability in
operation, durability and repairability. - Image improvement. Communicating a product's
environmental quality to users through an
environmental "seal of quality," such as the
Environmental Choice Label or a good report in
consumer tests, can improve a company's image
significantly. - Need to reduce costs. Companies can combine DfE
strategies with financial benefits by - Purchasing fewer materials for each of its
products. - Using energy and auxiliary materials more
efficiently during production. - Generating less waste and lowering disposal
costs. - Disposing of hazardous waste.
Need to stimulate innovation. DfE can lead to
radical changes at the product system level--the
combination of product, market and technology.
Such innovations can provide entry into new
markets. Employee motivation. Morale generally
increases when employees are empowered to help
reduce the environmental impact of the company's
products and processes. DfE can also boost
employee motivation by improving occupational
health and safety. A sense of responsibility. A
growing awareness that business must play an
important role in working towards sustainable
development can provide a strong incentive for
implementing DfE
21External Drivers
22- Government Policies. Product-oriented
environmental policy is growing rapidly in
northern Europe, the United States and Japan.
Some examples and trends - Legislation on "extended producer responsibility"
and "take-back obligation." Germany has
introduced a take-back obligation for goods such
as television sets, computers and cars. The U.S.
Environmental Protection Agency requires
discharge disclosures for certain types of
generators. - Introduction of eco-labelling programs for
products or product groups. - Requirement to provide environmental information
on products and processes, requiring business to
pursue more pro-active environmental
communication policies. - Development of industrial subsidy programs to
stimulate DfE activities and encourage companies
to carry out research into potential
environmental improvements. - Termination of subsides on energy-intensive
production methods and energy/raw material
consumption.
23- Market demand/competition. The needs/wants of
suppliers, distributors and end-users are
powerful drivers for environmental improvement.
Some examples and trends - Requirements by some companies--generally large
corporations--for environmental-safeguarding
declarations from suppliers. Some companies are
systematically looking at their entire supply
chain and imposing the new environmental
standards or other measures of environmental
performance. - Boycotts or other actions by consumer
organizations/environmental groups. For example,
Greenpeace successfully pressured industry to
develop GreenFreeze, an ecologically efficient
refrigerant made of propane and butane that can
replace environmentally harmful
chlorofluorocarbons (CFCs). - Environmental requirements incorporated into
consumer product testing. If a product fails to
get a high score on these requirements, it will
no longer qualify for the title of "best buy" or
"good choice," no matter what other excellent
features it may possess. Good environmental
ratings can increase market share. - Increased implementation of "responsible care
programs" in many industries, resulting in more
companies with experience in cleaner production.
In cases where intense competition exists for a
particular product, companies with a good
environmental profile can have an "edge."
24Waste charges. Waste-processing charges such as
land-fill and incineration costs are likely to
increase, based on the principle of "polluter
pays." The prevention of waste and emissions,
re-use and recycling will consequently become
more economic.
25- Environmental requirements for design awards.
Several respected design competitions have now
stipulated that contestants must provide specific
environmental information on their products. - One example is the German Industry Forum (IF)
Design Award, affiliated with the Hannover Messe,
which has a five-year plan to obtain
environmental information on aspects such as
packaging, materials used, re-usability and
warranties. Other international design
competitions now pro-active with regard to the
environment are - IDEA award in the United States.
- G-Mark award in Japan.
- Form Finlandia award by Nestle.
- Excellent Swedish Form by the Swedish Design
Council. - Brown Competition in Germany.
- ION award in the Netherlands
26Step 4 Analyze Improvement Options
- The project team should list improvement options
on the DfE Improvement Options Worksheet,
grouping them according to a classification based
on the seven DfE Strategies. The Improvement
Options Worksheet can also be reformatted to
include the DfE Sub-Stratgies. (DfE
STRATEGIES)After listing the improvement
options, the team can then use the DfE Strategy
Wheel Worksheet to visualize the main areas for
product improvement.
27- The DfE Strategy Wheel The team should plot the
existing product's environmental profile, using
the results of the MET Matrix Worksheet and DfE
Checklist Worksheet. (Step 2 Analyze Product's
Environmental Profile) - Assign a rating, from 0 (poor) to 5 (excellent),
according to the seven DfE Strategies. - Plot seven points on the Wheel along the
corresponding axis. - Connect all seven plotted points.
- The area generated is a visual representation of
the product's environmental profile. - Plot a second Wheel using the results from the
DfE Improvement Options Worksheet. The difference
in area between the two plotted surfaces is a
graphical representation of the level of
"ambition" for the DfE project.

29Strategy Wheel with current and targeted
environmental ratings
30- Short-term, long-term goals. The Strategy Wheel
can also help you communicate short- and
long-term goals. - For example, a power-tool manufacturer decides to
apply the DfE strategies to the design/product
development of its cordless screwdriver. The
current environmental profile for this product is
a "poor-to-fair" rating for all seven DfE
Strategies. - The team identifies two goals for the short term.
- Significantly improve performance in product use
by specifying a more efficient motor (Strategy 6
Reduce Impact During Use). The benefits are 1)
decreased number of times batteries have to be
recharged and 2) reduced cost of ownership for
the end-user. - Reduce injection-moulding waste by redirecting
plastic re-grind for use in a less critical
application product (Strategy 4 Optimize
Production Techniques). - The project team illustrates these short-term
priorities on the DfE Strategy Wheel by plotting
the screwdriver's existing profile and short-term
priorities.

32Cordless Screwdriver Long-term Goals
33- Step 5 Study Option Feasibility
- The DfE Priority Matrix Worksheet categorizes
each improvement option according to - Anticipated environmental merit.
- Technical, organizational and economic
feasibility. - Market opportunities.
- The project team should take note of those
options can be matched to the DfE drivers. (Step
3 Analyze Internal/External Drivers)
34Priority matrix worksheet
- The Worksheet can help a company systematically
establish DfE priorities. Experience with DfE
projects has shown that every area in the company
involved in product development--management,
marketing, purchasing, research and development,
and production--should have representatives
participate in a priority-setting
workshop/meeting. The group should - List and assign a priority rating to each
improvement option. - Label each option as a possibility for
implementation in the short term (ST) or long
term (LT). - The group can estimate technical feasibility and
market opportunities using techniques normally
applied in your company.
35Work out realistic solutions
- Work out the solutions selected as most promising
according to the defined project-specific
priorities, appropriate to the given overall
strategies and integrating the set environmental
and social goals and requirements
