engineering courses, communication skills are not taught explicitly;however, students are expected and held accountable for being able to speak and write well.Consequently, there is a need to change university engineering programs in order to provideopportunities for students to develop communication skills (Pet-Armacost, & Armacost, 2003).The importance and need for oral and written communication skills in engineering has beenclearly recognized. Engineering students who have good communication skills are more likelyto succeed and advance in the professional world than those who don’t.Team-Working Skills in EngineeringIn today’s work environment, project tasks generally involve the establishment of teams formedby people from different functional

others to constitute avirtual team” [1]. With the concept of virtuality, the notion of “working together apart” [2]very well captures the essence of what the virtual world presents to organizations. In fact,people no longer have to be confined in the same continent, let alone building or room, inorder to work on a project. The new face of organizations is that of a much decentralizedgroup, with diverse sub-groups dispersed all over the four corners of the world. Virtualteams and networked organizations are the latest stage in the evolution of organization [3].Virtual teams are a type of small group. They differ from other small groups in forms ofcommunication, number of relationships, and in the ability to create in a global context.The

Since numerous six sigma projects have been discussed in the literature, thistechnique could be implemented in the Engineering Management curriculum at both theundergraduate and graduate levels. One caveat is important. General Electric and others thathave embraced six sigma projects have found the revolutionary changes leading to productinnovations diminish over time.

As leaders attempt to create high performance andagile work environments, the importance of individual performance increases, which, in turn, relies onindividual employees’ well-being (health). This paper investigates to what degree, if any, prospectiveEngineering Managers understand the relationship between the implementation and execution of Leaninitiatives and increased levels of employee stress.The literature review associated with this project indicates that Lean activities can cause increased stressamong

number of graduate engineering managers beingpart of project teams that involve a substantial amount of quality / process managementactivities. As a result, it has become imperative for any graduate EM program to includequality/process management as a part of their EM curriculum. These courses on quality/processmanagement introduce the graduating engineering manager to a plethora of quality/processmanagement topics. However, not all of them receive an equal emphasis by the instructor, norpotentially by the organization they join post graduation, as well. However, there is aconsiderable dearth of open literature on EM education discussing the relative importance ofquality/process management topics that are taught as a part of any graduate EM

repeatedlyobserved that most of the fresh graduate Engineering Managers generally enter an organizationnot just as a traditional hardcore engineer, but also as project managers, technical sales people,systems engineers, systems analysts, and so on (Abel, 2005; Farr and Kotnour, 2005). As aresult, the competencies of a typical engineering manager should extend well beyond thetraditional engineering skills to technical and managerial skills as well, and with the blurringboundaries between engineering/technology and management, these overlapping roles can proveto be very important for an organization to remain relevant in the modern economy.The rapidly growing importance of engineering managers in the industry has in turn led to agrowing importance of EM

Academy of Engineering(NAE) has identified that the engineers of 2020 need to have strong analytical and problemsolving skills while being readily adaptable to advancing technologies in a globally connectedworld (1). A classroom syllabus typically contains conventional lectures and a group project. Itmay also contain a business example provided by a guest lecture or case study. These currentteaching methods have displayed positive results, but barriers between academia and industrycan be made seamless by incorporating both advances in technology and motivational techniques(2) . Students will find the transition to be more cohesive after they have completed a curriculumthat facilitates superior student understanding.Initial Assessment: Learning
