The traditional career model—graduate from college, enter an industry, climb the corporate ladder through defined steps, retire with a pension at 65—was always more myth than reality for most workers. In the 21st century, with average job tenure shrinking, entire industries transforming, and the concept of a "career" increasingly fragmented, the ladder metaphor is less useful than ever. Understanding how careers actually develop, and how to navigate them deliberately, requires abandoning the ladder for more accurate frameworks.
The Career Lattice vs. The Career Ladder
The career lattice model, proposed by researcher Ravenna Hogneby and popularized by organizations like the Families and Work Institute, describes modern careers as lattices—allowing movement up, down, sideways, and diagonally—rather than ladders that only allow upward movement through hierarchical levels.
Research by Mary Ellen Vest and colleagues documents the shift: younger workers (Millennials and Gen Z) prioritize different dimensions of work than previous generations, including flexibility, meaning, learning, and work-life integration. These priorities don't always align with ladder-climbing, leading to non-linear career paths that appear chaotic by traditional metrics but may serve actual values better.
The "Slash Career" Phenomenon
Research by Sir Richard Branson and others has documented the rise of portfolio careers—people who combine multiple income sources (e.g., "accountant/yoga instructor/real estate investor" or "engineer/writer/consultant") rather than holding a single job. The COVID-19 pandemic accelerated this trend, with studies showing significant increases in side gig participation and freelance work.
The portfolio career offers resilience (income from multiple sources reduces dependency on any single employer) but requires managing multiple professional identities, tax situations, and client relationships. It's not for everyone, but for many it's more realistic than traditional employment.
Skill Transferable Mapping
A key insight from career research: skills are more portable than jobs. Rather than planning specific career moves, mapping transferable skills allows more flexible navigation of career changes.
Research by the Harvard Business Review on transferable skills identified several categories:
- Communication skills: Writing, presenting, negotiating, listening, explaining complex topics
- Analytical skills: Research, data analysis, logical reasoning, pattern recognition, problem diagnosis
- Management skills: Planning, organizing, delegating, coaching, performance management
- Creative skills: Ideation, design thinking, visual communication, prototyping, improvisation
- Relationship skills: Networking, collaboration, conflict resolution, stakeholder management, trust building
The exercise: list skills you've developed (from any context—paid work, education, volunteering, hobbies), then identify industries or roles where those skills are valued. The skill-based approach decouples career planning from specific employers or titles.
"The skills you bring to work today are the foundation for the work you'll do tomorrow. Jobs are temporary; capabilities are permanent." — Gary Bolles, career researcher
Network Effects on Career
Research consistently shows that career opportunities come disproportionately through networks rather than through formal applications. A study by Wayne Baker and Robert Cross of the University of Michigan found that both the quantity and quality of professional connections predicted career success more strongly than traditional credentials.
Mark Granovetter's foundational 1973 study "The Strength of Weak Ties" found that most job changers learned about new positions through casual acquaintances rather than close friends. Weak ties—relationships that aren't emotionally intense—are valuable because they connect you to information circles beyond your immediate network. Your close friends tend to know the same things you know; acquaintances know things you don't.
The implication: building and maintaining a diverse professional network—even connections that feel superficial—creates career optionality. Networking isn't just for job seekers; it's career infrastructure that creates opportunities before you know you'll need them.
Deliberate Practice Applied to Career
K. Anders Ericsson's research on deliberate practice—the type of focused, feedback-driven practice that produces expertise—has been applied to career development with interesting results. His findings suggest that merely accumulating years of experience doesn't produce expertise; what matters is the quality of practice during those years.
For career development, deliberate practice means:
- Seek discomfort: Growth happens at the edge of current competence. Staying in comfortable roles produces comfort, not growth.
- Get feedback: Without feedback, improvement plateaus. Seek managers, mentors, or peers who will tell you honestly how you're performing.
- Focus on weakness: Conventional wisdom says play to strengths. But for career advancement, addressing critical weaknesses (communication, leadership, technical gaps) often matters more than further strengthening strengths.
- Practice specifically: General reading and learning are less effective than specific practice on specific skills. If you want to improve at presenting, present.
The Portfolio Career Trend
The Bureau of Labor Statistics data shows that Millennials change jobs approximately every 2-3 years, far more frequently than previous generations. This job-hopping behavior has been criticized as lacking loyalty, but research suggests it often reflects strategic career building.
Studies of career success find that early-career job hopping can accelerate learning and salary growth by exposing workers to diverse industries and skills. The optimal strategy appears to be: stay long enough to learn something (typically 1.5-2 years minimum for most roles) but don't stay so long that you stop growing.
Practical Career Planning Protocol
Nonlinear Career Planning Framework
Step 1: Map Your Skills, Not Your Job Title
Write down every skill you've developed—technical skills, soft skills, from any context. This list is more valuable than your resume for career planning. Identify which skills are transferable to other industries and roles.
Step 2: Identify Your Career Vectors
A career vector is a direction of growth, not a destination. Instead of "I want to be a VP," ask "In what directions do I want to grow?" Possible vectors: more technical depth, more leadership scope, more creative latitude, more geographical flexibility. Vectors help you recognize opportunities that align with your growth.
Step 3: Build Network Edges
Actively cultivate weak ties—connections beyond your immediate team. Attend industry events. Connect with people in roles or industries you find interesting. These connections become future opportunities and information sources.
Step 4: Practice Deliberately
For your key development areas, create deliberate practice opportunities. If leadership, volunteer to lead projects. If public speaking, seek presenting opportunities. Practice without feedback produces slow improvement; seek feedback aggressively.
Step 5: Review and Adjust Annually
The career lattice requires regular recalibration. Annually assess: What skills have I developed? What skills do I need next? What vectors am I growing along? Are my current opportunities aligned with my vectors? Adjust based on what you learn.
The Honest Assessment
Modern careers aren't built through planning alone—they're built through experimentation, relationship, and adaptation to changing circumstances. The workers who navigate them best aren't those with the most detailed plans but those with the clearest values, the most transferable skills, and the largest networks.
The traditional ladder still exists in some industries and organizations. But for most people, the lattice—sideways moves, diagonal jumps, temporary retreats, portfolio combinations—offers a more realistic and often more satisfying career path. The skill is not following a predetermined path but developing the capabilities and connections that make productive career navigation possible.
