Excel in Your EngineeringWhen I reflect on my 20-plus years of experience as a chemical engineer, I realize how wonderful my profession is. As engineers, we provide the essential link between technology and humanity. Our job is to make the world better for its human inhabitants while protecting the environment. And we fulfill our mission amongst the demands and guidelines of the business world.But sometimes we get so bogged down in the everyday aspects of our jobs that we lose sight of the big picture. We forget to appreciate engineering—though it is challenging, creative, interesting, significant, and even fun.For example, there’s nothing like getting engrossed in a tough technical problem and coming up with a neat solution. Do you find yourself hurrying to the office because you look forward to working? Do you ever wake up in the middle of the night thinking about a problem and lie there working out the details of a brilliant solution? Do you get up to write notes so you won’t forget your breakthrough in the morning?Engineering can be that wonderful. And being involved in your work doesn’t mean you’re a nut or a workaholic. We should like what we do: Enjoying something and doing it well is a“chicken-and-egg” situation. We tend to like activities we per form well, and to be good at things we enjoy. So here’s some advice for both enjoying and improving your engineering work.1.Enhance technical skillsEngineering provides many opportunities to develop existing skills and to learn new ones. In fact, we have to keep learning or we atrophy--that’s the nature of any profession. The ability to grow is one reward of a good job. As your interests and involvements change, and as technology changes, you need to keep learning.2.Hone interpersonal skillsNot all the development opportunities relate to technical matters. Successful engineering practice is strongly dependent on interpersonal and communications skills. It’s important to learn about people, motivation, organizational behavior, written and oral communication and visual aids. With these skills as with any others, practice makes perfect (or at least very proficient).In addition, remember that we are also “business people” and, as such, should keep up on trends in the business world, particularly in our industry. These communications skills can help develop relations both within and outside the company.Activities outside of the workplace can be good opportunities for enhancing nontechnical skills. They can help you improveinterpersonal, leadership and communication capabilities.For example, it’s easy to get into leadership positions in volunteer organizations. All you have to do is attend some meetings and show that you’re willing to help out, and soon you’ll move right into whatever you want to do.3.Do the whole jobYou’re probably familiar with the concept of “completed staff work” (CSW). According to this concept, a subordinate presents his or her boss with solutions, or at least options, rather than problems. The reasoning is that the person closes to the problem is better prepared than anyone—even the boss—to make a decision and to implement it. Decision are best made at the lowest practical level.Before passing your work on to the boss, try to make the work as complete as you can. That means not only writing the report, but also the cover letter and any transmittal notes it will need to flow smoothly through channels. Think through any political ramifications and make appropriate contacts to preclude problems. Anticipate questions and prepare for them. If your boss looks good, you look good.By maximizing the quality and quantity of your work, you maximize your value to your employer. Learn to do many things well. Be the engineer who can write a project proposal, plan and performexperiments, design equipment, analyze data, develop a mathematical model, write and present results, and bring in the next job. If you do it yourself—or lead others in doing it—or you will be indispensable.4.see the big pictureMany engineers with little experience view their job too narrowly. They’re content to just do what they’re asked. They may be creative in carrying out designated tasks, and they may see some minor extensions of it, but they don’t explore widely enough.But the “big picture” is not just the concern of higher-level people. Everything that happens in the company affects all of its employees. In turn, each employee can contribute to the well being of the company.You can get involved in long-range planning, business development, and diversification into new products or services. The people who are already involved in these matters will welcome your help. Although you might start out with a small role, you will soon be contributing more and more. Such efforts often begin by demanding a little more of your personal time, but are later sanctioned by your supervisors as you prove your capability.5.Be a leaderThere’s always a need for leadership of technical activities, andmany engineers are suited to this. Leaders aren’t born; leadership skills are developed.Leadership is different from management. For example, consider a large group of people in a jungle; their task is to cut a path through the underbrush. Managers recruit the workers, teach them how to use a machete, provide them with appropriate clothing, arrange their transportation to the job site and ensure that they are fed.But the leader is the one at the front of the group, showing them where to cut the path. Pr perhaps the leader tells the group that this is the wrong jungle and they need to go elsewhere.Managers take charge f administrative, executive and business matters. They supervise employees’ work to make sure that operations are flowing smoothly. Leaders, on the other hand, are those who break ground, bring in new technologies, and point the way toward innovation.You don’t have to have any assigned management responsibility to be a leader. People respond to leaders—with or without prestigious titles.As a matter of fact, you may be able to develop true leadership skills better if you don’t have admin istrative responsibilities. When you don’t have jurisdictional authority over people, you find otherways to influence them. Instead of ordering people to do things, you make them want to do them—and that is the best way.1.Be a mentorAs we gain experience, we can help younger engineers develop their potential. People pick up a lot of their attitudes toward work, approaches to problems, and working methods from their senior colleagues. If you are a senior engineer, your impact on new employees is particularly strong and important.New engineer should be able to take a sufficiently broad view of their jobs and not limits themselves. It is rewarding to accomplish work through others, to see them develop into stronger engineers and move into positions of more responsibility.Sometimes part of your success as an engineer may be hiring or training someone who goes on to do things you can do yourself. You can help a promising engineer with capabilities beyond your own. And if you have a hand in developing someone who goes on to a really high position in your company, be proud of your accomplishment.2.Beware of diversionsA multifaceted profession, engineering involves other disciplines. But think about your chosen path before becoming involved in a peripheral area.For example, many engineers become enamored with computers. Today is personal computers can certainly enhance out productivity. Remember, however, that a computer is a tool just like a telephone or a calculator. Do not let yourself value the means over the end. If you are working on computer tasks that support personnel can do more efficiently, you are probably not employing your time well.Some engineers are so fascinated to computers that they have in reality shifted from being engineers to being computer scientists. There’s certainly merit in doing what you enjoy, but issue a caution. Remember that you had good reasons for going into engineering in the first place, and if you drift into another area, you may later find it difficult to return to your engineering duties.Management is another popular diversion. For some engineers, going into management is a positive move. Management is challenging and rewarding, and many engineers are well suited to it. In addition, having an engineer-turned-manager is helpful to the other engineers. Moving in and out of management position, especially in the lower levels of management, can actually be good for an engineer’s career.However, the longer you stay in management, the more you run the risk of no longer being able to return to engineering. Most engineers who move into lower-level management positions are wiseto regard them as a temporary diversion from their true profession.3.Keep fitGood health is essential to doing a good job. When you’re fit, you have more energy and feel better generally. Thus you can put more onto your work, a well as into there aspects of your life. Because most engineers have predominantly sedentary jobs, it is important to eat carefully and get enough exercise.4.Enjoy your professionAs professional engineers, we need to keep developing and broadening our skills. We need to expand the scope of our work and reach the full potential we have, to the benefit of both ourselves and our employer. For most engineers, the best job security is being able to do high-quality engineering work, which is always in great demand. Finally, we should relish the varied challenges and excitement that constitute engineering at its best.。
