    problem statement

    The design process normally begins withdeveloping a statement or definition of the

    problem.An essential part of any problem statement is

    the goal that one wants to achieve.

    Goals are broad statements of intent, that haveto be elaborated into more specific objectives, tobe useful for decision making in design.

    The list of objectives, stemming from differentstakeholders in, and affected by the designproject, is called the design specification.

    What is a problem?

    To solve a problem, we first have to

    acknowledge the existence of a problem, and

    understand what the problem is.

    What is a problem?

    what does a problem definition consist of, and

    how do goals and objectives fit in?

    relative nature of problems

    Every evaluation is based on a value system,and this value system is not the same foreveryone.

    Moreover, an individuals value system maychange in the long run.

    Also, the problem-owner does not evaluate asituation as such, but an imageof the problemsituation; differences in understanding of a

    problem are easily caused by the personal viewthat is taken.All this sufficiently explains the relative nature of

    problems.

    more desirable

    A situation is only a problem if the

    problem-owner wishes to, and can, dosomething about it, through a certainaction.

    This implies that a situation must beconceivable that is more desirable than

    the present one: the goal situation

    What is the problem?

    The existing state must be defined, as well asthe problematic aspects that are experienced init.

    This is also called the status quo.

    It is, however, more important to investigatewhat causes the status quo, and how it willdevelop, if nothing is done.

    Explanations have to be found for theproblematic facts, and predictions have to bemade as to how the problem is likely to develop.

    thinking of goals

    Discontentment with a situation is not morethan a signal.

    To solve a problem, situations which are moredesirable must be conceived of.

    In a way, thinking of goals is in itself aproblem-solving process, as goals have to beconceived, and that entails difficult choices.

    Nevertheless, something of a goal should begiven, preferably formulated as concretely aspossible.

    undesirable side-effects

    For goals one thinks normally of the aspects which haveto be present in the new state.

    However, often also certain things have to be avoided.

    There is a strict rule which says: no effect without aside-effect.

    Each technical intervention has unintentional, and oftenundesirable, side-effects, and thus the solution for aproblem might create new problems.

    The undesirable side-effects should be identified andmade part of the problem definition.

    constraints

    Each problem has controllable and uncontrollablevariables.

    We can only control an undesired situation byintervening in the existing state.

    But often we cannot or may not change everything. The means design is in many cases subject to

    restrictions. So there may be certain constraints, within which a

    solution has to be found.

    These constraints are also part of the problem definition. For example: may a certain material or production

    technique be used or not? The time, budget, and other means for solving the

    problem are also constraints.

    problem definition

    The activities leading to a problem

    definition can be summarized as follows:(a) observing and describing,

    (b) explaining and predicting, and(c) identifying and formulating goals and

    objectives.

    Basic Steps in Problem Solving.

    You decide you want to solve theproblem.

    You get information about the problem.You need to understand the problem.

    You find a solution.You implement the solution.

    The Innovation Process is very similar but is fundamentally different from mostlinear single solution focused methods.

    Preparation of Design Problems Design problems are usually complex, in as

    much as they have several goals, manyconstraints and an even greater number ofpossible solutions.

    In designing a new product, you will betrying to satisfy the needs of a wide range of customers, exploit to the full the abilities of sales, marketing and

    distribution channels,

    fit in with existing manufacturing facilities andsuppliers and end up making a profit for the company.

    Defining a design problem to take account of allof this takes a lot of preparation.

    Why is it a problem?

    Exploring, expanding and defining a problemseeks answers to several questions.

    Exactly what problem is it that you are trying tosolve?

    Why is it a problem? Is it apart of a bigger or more general problem?

    Would solving this more general problem also

    solve the immediate problem? Is, therefore, the immediate problem the best

    problem to be tackling?

  • 8/14/2019 20080701-230-

    three key characteristics

    What is the ideal solution to the problem? What is it about this solution that makes it ideal? Is this solution ideal only in particular

    circumstances and if so, what are thesecircumstances?

    The answers to these questions shouldestablish three key characteristics of theproblem:

    1. the problem goal,2. the problem boundaries and3. the problem gap.

    problem definition

    This exploration of the problem aims to reach asimple, concise and workable definition.

    It should specify the problem goal sufficiently sothat you know when a solution has been found.

    It should also allow potential solutions to be

    compared and ranked according to how wellthey solve the problem.

    The problem definition must also define the

    problem boundaries. These define the limits of acceptability for

    potential problem solutions.

    1st levels of commitment (commitment)

    They must specify what the product must achieve,

    in business terms, to exploit that opportunity.

    They must also present a financial justification forthe proposed investment in developing the newproduct.

    The document containing these businessobjectives is called an opportunity specification.

    2nd levels of commitment Secondly, commitment must be made to a more

    flexible specification of the specific technicalfeatures of the new product.

    These technical features, regardless of how they

    may be modified during product development,must always remain sufficiently focused toensure that the agreed business objectives are

    met.

    This technical description of product objectives

    is called a

    Most importantly, it achieves a nice

    balance between effective quality controland innovative freedom.

    Provided the technical specification

    remains faithful to the business objectives, it can be changed, if necessary, to take

    account of new ideas which emergeduring the product design process

    The opportunity specification is prepared at the

    very start of the product development process.

    It makes the case to management that there isa viable business opportunity to be exploited,even though it is not yet known what designfeatures the new product will have.

    Approval of this opportunity specification allows

    concept design to be completed with the aim ofdeveloping a set of functional and stylingprinciples which exploit the specified opportunity.

  • 8/14/2019 20080701-230-

    Once these design principles are

    established, the product can be specifiedin more detail.

    Specific design targets can sensibly beproduced now that it is known what typeof product is going to be developed.

    In other words, the design specificationcan be written after concept design is

    complete. Baxtor1995 p. 164 2004

    core benefit proposition

    The core benefit proposition should be a

    simple common sense statement describingthe advantage the product will have relativeto others in the market.

    It should be the sort of statement thatcustomers would understand, and may,indeed, form the main advertising line for

    subsequent marketing of the product. Baxtor1995 p. 165 2004

  • 8/14/2019 20080701-230-

    47/69

    Given that the product has the advantage

    specified in the core benefit proposition,

    how does it compare in terms of other aspects of function,

    in terms of price or in terms of appearance.

  • 8/14/2019 20080701-230-

    It should be quite sufficient to relate to other

    products on the market.

    So, the new product will be better thancompetitor A, will include listed features from

    competitors B, C and D, and, as we have saidabove, it will be priced no higher than the 75thpercentile of all competing products.

    Also, the opportunity specification does

    not need to be a comprehensive list of allaspects of the new product.

    It just needs to cover the key factors inmaking the product a commercial success.

    significant business opportunity

    A significant business opportunity exists only

    when there is an identifiable difference betweeni) the demands and wishes of customers and

    ii) the products offered by competitors.

    This business opportunity can only be exploitedwhen the available technology allows a productto be made which satisfies the previouslyunsatisfied market demands.

    Product trigger: market pull

    Market pull refers to the demand by the marketfor a product or product features not currentlyoffered by your company.

    This market pull may be recognized in two ways.

    Firstly, competing products may be edgingahead of your present products, creating amarket demand for you to enhance yourproducts in order to catch up.

    Secondly, there may be market needs notcurrently satisfied by any existing product.

    competing product analysis

    It is usual to start analyzing competing productsbefore researching markets.

    This can give the subsequent market research amuch clearer focus and allow more structuredand meaningful questions to be asked to

    potential customers. To describe the variety of ways existing products

    will compete with the proposed new products.

    To identify or evaluate opportunity forinnovations. To set targets which the new product must meet

    in order to compete effectively.

    where to draw the line

    where to draw the line on competing productsshould be firmly based on market forces.

    The choices customers face when making apurchasing decision will obviously depend upon

    the range of products stocked in the target salesoutlets for your proposed new product.

    These stocked competitors must, therefore, be

    the focus for all competing products analysis.

    65/69

    2.Judgment for characteristics

    Judgment is also needed in deciding what

    characteristics of competing products to study. What you want to know about competing

    products obviously depends upon how you

    see these products competing with yourproposed new product.

    If the companys strategy is to produce basic,

    low price products, then the price ofcompeting products and the design factorswhich determine their cost of manufacture

    will be of greatest importance. Baxtor1995 p. 171 2004

    66/69

    3. Setting targets

    Setting targets, as described earlier, is the

    main aim of product planning. In preparing an opportunity specification,

    the type of targets you need to set are

    those of relevance to the businessperformance of the proposed new product.

    These generally amount to price andmeasures of product value
