1.CourseInformationThefollowingisthecoursecatalogdescriptionofME497/8,SeniorDesignProject:
Projectof thestudent'schoice iscarriedthroughfromproblemformulationtocompletion.Thissequencerepresentsthestudents'majordesignexperienceandisbasedonknowledgeand skills acquired in earlier courses. Design criteria and objectives are formulated, andrealistic constraints including economic, environmental, sustainability, manufacturability,ethical, health and safety, social, and political are considered. Engineering analysis andsynthesistechniquesareappliedanditeratedtoobtainanoptimaldesignsolution.Studentsdesign and conduct experiments to verify design performance. Students document theirachievementsthroughoralandwrittenpresentations.

KeepingRecordsSomerecordshouldberetainedofalltransactionsofteammeetingsthroughouttheyear.Therecordshouldincludemajordecisionsandbasicassumptionsmade,andshouldclearlyidentifyactionitemstobecompletedandbywhom.Keepmeetingagendas and minutes is encouraged; they are a record of what your team haslearned,decided,andaccomplished;andwhatyouhaveplannedtodoandhowyouplantoaccomplishit.Minutesshouldinclude:● Date,location,time,andpeoplepresent ● Itemsaccomplishedsincethelastmeeting ● Individualresponsibilitiesfornextweek’swork ● Newfactsanddata;changedworkplan;problemsorquestions,etc.
CommunicationThe effective communication of technical ideas is a critical skill for engineers.

Facultyadvisorsarenotprojectmanagers,but academic advisors for these student projects. The responsibility for projectmanagementandproductionofdeliverableslieswiththeteam,andwiththeteam’sproject manager.

WorkingwiththeMachineShopStaffThe shop supervisor and technicians act as both consultants and contractors onyour senior design project. Clear, timely communication with the machine shopsupervisor is vital, and must be carried out in a professional manner.
