IntroductionThe chances of a product being developed on time and within budget are dependant on thoroughand precise analysis of the client's current situation and needs. Informally, the client’s needs arealso called “requirements.” A “requirement” is a specification of what should be implemented bya product. The IEEE standard defines requirement as “A condition or capability that must be metor possessed by a system or system component to satisfy a contract, standard, specification or Page 7.748.1 Proceedings of the 2002 American Society for Engineering Education Annual

To this end, I give an early readingassignment in Statics - Vicky Hendley’s article, “The Importance of Failure.”1 In the article,Hendley lists examples of failures that led to great successes, discusses the importance of learningfrom failure, and introduces issues in ethics and professional responsibility. By noting that amistake offers more opportunities for learning than a successful answer, students are less likely tobe averse to examining their mistakes.Henry Petroski writes, “Treating every case of failure as an opportunity to test hypotheses,whether imbedded in design or in theories about the nature and process of engineering itself,makes even the most ancient of case studies immediately

Major freewaydamage occurred up to 32 km from the epicenter. Collapses and other severe damage forcedclosure of portions of 11 major roads to downtown Los Angeles.

Theessential element in this configuration was that all the transducer signals remained in analogform up to the workstation enclosure. The analog to digital conversion was performed inside theworkstation enclosure.

This process substantially reduces the assessment -improvement-verification turn-around time, making it easier to determine the effectiveness of teaching orcurriculum changes on the learning experience.

Humor, spontaneity, variety of activity, animated delivery,enthusiasm for the subject matter, and the presence of drama in the classroom can help fostersuch emotions. It may appear difficult upon first glance to imagine how one brings drama andflair into the engineering world of derivations, complex equations, and code requirements. Ittakes more imagination than a class on law or history, which seem to lend themselves better todramatic effect.
