The First Thing You Must DO Often design project statements are often verbal, and sometimes quite short. These two qualities suggest that the designers ±rst task is to clarify what the client really wants and translate it to a form that is useful to the design engineer When you ±rst form your team… you should do the following Write down a problem statement this should express as speci±cally as possible what the problem is and should include: objectives and goals the current state of affairs and the desired state any constraints placed on the solution of the problem the de±nition of any special technical terms

Objectives Tree • What is it? – A method of generating an ordered list of what the design has to do to meet the client/user needs • Why you want to use it? – Provides a simplified view that is easy to follow – Provides a logical framework to your client during your design review – Helps the client to become more involved

What is an objective? • Objectives or goals are the desired attributes and behaviors that your client would like to see in the final design • They are BEING statements – They explain what the design will be not what the design must do “Stiff” is a being statement • Typically measurable (think Material Properties!) • Written as statements that “more (or less) of the [objective] is better than “less (or more) of the [objective]”. Example: lighter is better than heavier • Taken from the clients problem statement – Contains abstract and concrete requirements • Example: “safe and reliable”

What objective is not • Constraint – Restrictions or limitations on a behavior (design will fail if these restrictions or limitations are not met) – A value or some other aspect of a designed objects performance – Examples : the beam cannot have a deflection more than 0.05 in, must meet ISO 9000 standards, costs less than $5 • Constraints will become important later in the design, if used in
