Published in 1944 yet still indispensable, "The Unwritten Laws of Engineering" reveals the hidden social dynamics that determine engineering success more than technical skills. For 75+ years, this timeless classic has shaped professional standards across industries - what career-defining wisdom are you missing?
W.J. King (William J. King), author of The Unwritten Laws of Engineering, was a distinguished engineer and educator whose work reshaped professional development literature.
Originally published in 1944 by the American Society of Mechanical Engineers as a guide for new engineers, his book evolved into a cross-industry classic on workplace dynamics and leadership principles.
A former General Electric engineer and longtime UCLA engineering professor, King drew from decades of industrial and academic experience to craft pragmatic advice for navigating organizational hierarchies and technical challenges. His companion work, The Unwritten Laws of Business, further expanded these principles for managerial audiences.
King’s succinct, actionable maxims—emphasizing ethics, interpersonal skills, and systemic thinking—remain foundational in engineering education and corporate training programs worldwide. The book has been republished in over 30 editions and translated into 40 languages, cementing its status as a perennial resource for professionals seeking to master the unwritten rules of career success.
The Unwritten Laws of Engineering by W.J. King is a professional guide addressing non-technical challenges in engineering careers. Originally published in 1944, it outlines practical "house rules" for workplace conduct across three areas: essential advice for beginners, leadership principles for managers, and personal/professional ethics. The book emphasizes administrative wisdom, interpersonal dynamics, and proactive problem-solving over technical skills.
This book is essential for new engineers, technical managers, and professionals seeking career advancement. It’s particularly valuable for those struggling with workplace dynamics, communication, or leadership challenges. Experienced engineers also benefit from revisiting its timeless principles to refine their professional conduct.
Yes. Despite its age, the book remains a cornerstone of engineering literature for its concise, actionable advice. Reviewers praise its focus on soft skills—like communication and accountability—that are critical for long-term career success. The 60-page format makes it a quick yet impactful read.
New engineers should:
Managers learn to:
Key personal guidelines include:
A hallmark line advises, “Let’s go see!”—encouraging engineers to investigate problems firsthand rather than relying on secondhand reports. This embodies the book’s emphasis on proactive problem-solving and collaboration.
Both books share W.J. King’s core principles, but The Unwritten Laws of Business broadens the audience to non-engineers. The original engineering-focused version includes industry-specific examples, while the latter adapts advice for general corporate settings.
Its focus on human dynamics in technical fields transcends technological changes. Remote work, AI integration, and interdisciplinary teams amplify the need for soft skills like communication and adaptability—areas the book addresses comprehensively.
W.J. King was a General Electric engineer and UCLA professor who wrote the book in 1944 after observing workplace failures stemming from poor professional conduct, not technical errors. His pragmatic insights stemmed from decades of industry and academic experience.
Some note its brevity and lack of technical depth, but most agree its purpose—to codify implicit workplace norms—is fulfilled effectively. Modern readers may need to contextualize older examples, but the core principles remain universally applicable.

Engineering education equips you with formulas and technical knowledge, but leaves a critical gap in professional conduct that determines your ultimate success. When W.J. King published "The Unwritten Laws of Engineering" in 1944, he created what Bill Gates would later call "a book I'd recommend to every engineer." This enduring classic reveals a fundamental truth: technical skills may get you hired, but your professional behavior determines how far you'll go. While you're mastering thermodynamics and calculus, no one teaches you how to navigate office politics, manage relationships with supervisors, or lead teams effectively. Yet these unwritten rules make the difference between stagnation and stellar advancement in your engineering career.
The most counterintuitive lesson for new engineers? Your approach to minor tasks will determine your trajectory more than your technical brilliance. Many young engineers consider routine assignments beneath them, awaiting opportunities to prove themselves through major projects - this is backwards thinking. Your handling of seemingly trivial responsibilities shapes your reputation profoundly. Rather than strategizing career moves, excel at your current responsibilities. Develop what King calls "the ability to get things done" - a combination of initiative (energy to start), resourcefulness (finding ways around obstacles), and persistence (completing what you begin). Many brilliant minds become known as "good starters but poor finishers" who abandon projects when new ideas capture their attention. When facing obstacles, seek immediate workarounds rather than accepting delays. Cultivate the "let's go see!" attitude - inviting stakeholders to investigate equipment problems together instead of speculating from your desk. Master communication by stating your main point first, then adding relevant background, avoiding the common trap of burying conclusions beneath excessive preliminaries.
No relationship impacts your early career more than the one with your direct supervisor. This relationship requires navigating sometimes contradictory principles with finesse. Keep your supervisor thoroughly informed. Managers typically struggle to extract enough information rather than receiving too much. When technical difficulties arise, present them promptly alongside potential solutions. No manager likes surprises, but solid recommendations transform difficult situations. Your supervisor's requests take priority - even if you believe other tasks are more important. These visible assignments often impact your performance rating more than less conspicuous projects. When given a specific task, either do exactly what was requested or return to discuss it further. Never ignore tasks or substitute your own approach without consultation. This doesn't mean blind deference. Don't show excessive timidity by constantly seeking minute directions. Management directives are generally guidelines formulated without information discovered during execution. Keep others informed of your progress, and seek approval for well-considered deviations when necessary.
Engineering never happens in isolation. Your effectiveness depends on collaborating across organizational boundaries. Success requires building productive relationships spanning multiple departments - from operations and finance to marketing and customer service. The cardinal rule? Never invade another department's domain without the knowledge and consent of the manager in charge. This common offense causes trouble when: employing someone else's subordinate directly; committing another department to work without consultation; making promises involving other departments; or performing functions assigned to others. These violations breed resentment, foster confusion, and typically indicate you're neglecting your own responsibilities. In all transactions, "deal in" everyone with a legitimate stake. It's easy to overlook stakeholders - like implementing technical changes without consulting maintenance teams or modifying processes without involving safety personnel. Even when no apparent harm results, people resent being excluded from matters affecting them. When dissatisfied with another department's service, address your concern directly to the individual responsible - not their supervisor. Complaining over someone's head damages working relationships. Similarly, copying a person's supervisor on complaint emails can be offensive, implying you don't trust their ability to address the situation.
The transition from individual contributor to manager represents one of the most challenging career shifts engineers face, requiring skills beyond technical expertise. As a manager, maintain awareness of your domain without micromanaging. Delegate responsibility even when you could handle tasks yourself-failing to do so is unfair to subordinates and creates dependency. Good executives ensure their organization runs smoothly in their absence. With limited time, focus only on what you're directly responsible and accountable for. Leverage all available resources and expertise, reserving your attention for areas where you bring special talent. The notion that anyone can do anything with enough effort leads to inefficiency. Develop the habit of "boiling matters down" to their simplest terms. The ability to reduce complex situations to essential elements is wisdom. Practice integration, condensation, and simplification rather than expansion and complication. This mental discipline becomes invaluable as you advance. When possible, prepare for major announcements by consulting key personnel in advance. This diplomatic approach, while basic in politics, is often neglected in engineering. Failing to consult those affected by changes creates avoidable resentment and embarrassment.
Successful project management requires overcoming "technical tunnel vision" - the tendency to focus solely on your expertise while neglecting other aspects. Develop foresight to plan the "whole" project early, considering all stages from initial design through market delivery. Elements like inventory planning, regulatory approval, user instructions, and promotional materials are as crucial as engineering design itself. A brilliantly designed product may fail if user manuals are unclear or regulatory compliance wasn't addressed early. In a competitive world, excessive caution often creates greater danger. Engineering managers should undertake bold development programs, setting high marks and working aggressively to meet them. Competent organizations produce their best work when pushed beyond comfort zones. Creating your own emergencies proactively beats having competition force them upon you later. Knowing when to stop development is critical - generally when you've met design specifications and budget with just enough time to complete the program on schedule. Design engineers often chase improvements while missing commitments. Remember that improvements will continue, but launching on time with a product meeting specifications trumps delaying for perfection.
While engineering education emphasizes technical training, emotional competencies-communication, interpersonal skills, self-control-contribute significantly more to superior job performance than cognitive abilities. Intelligence and technical knowledge are necessary but insufficient; those lacking technical capability are typically filtered out before employment. Perhaps the most valuable personal trait is the ability to get along with diverse people. This quality stems from good-natured friendliness and following the "Golden Rule": appreciating others' strengths, controlling impatience, avoiding grudges, and maintaining a healthy sense of humor. However, don't sacrifice principles just to be agreeable. Stand your ground in necessary conflicts when you know you're right. If you're easily pushed around, you will be. Respect comes from demonstrating readiness to engage in principled (non-personal) disagreements when warranted. In the long run, nothing surpasses the importance of integrity. Beyond ethics, integrity builds others' confidence in you. When your word is your bond, transactions become simpler. Character becomes remarkably transparent in an engineering office-people are quickly recognized for exactly what they are. Your actions speak so loudly that others cannot hear contradictory words.
