The Career Lattice: Designing Growth Paths That Don't Just Go Up

For decades, the career ladder was the default mental model for progression. You started at the bottom, and success meant climbing rung by rung towards the top. That image is now showing its age. As organisations flatten, skills cycles shorten and employees redefine what a good career looks like, the ladder is quietly losing its grip. In its place, a more flexible model is gaining ground: the career lattice.

A career lattice is, at its simplest, a structured approach to non-linear growth. It enables career growth up, across, and diagonally through a combination of role changes, capability building, and curated experiences. For HR, OD and L&D teams, the lattice is less a trend to chase and more a practical response to how careers actually unfold today.

Why the Ladder is Losing Relevance

The conditions that made the ladder work no longer hold. The corporate ladder was made for a time when job descriptions did not change for decades, companies could guess what skills they would need in ten years, and workers expected to stay in one job for most of their careers. Few organisations live in that world anymore.

Three shifts are driving the change. First, structures are flatter, so there are simply fewer rungs to climb and longer queues for each one. Career ladder systems typically emphasise seniority and tenure over skills and performance, leading to talent bottlenecks when qualified employees have no upward mobility options. Second, skills are turning over faster. By 2030, 39% of the most important job skills will have changed, which means a company that keeps its workers in one narrow lane is making them less flexible at the worst possible time. Third, employee priorities have moved on. Success is no longer defined by steadily climbing the ranks within a single company; it's about exploring diverse roles and experiences.

The cost of ignoring this is real. In 2024, a survey of more than 800 companies from different fields found that 90% of HR leaders said their employees do not know what their career path is. Clarity, not just opportunity, is the gap to close.

The Four Movement Types of a Lattice

A useful way to make the lattice concrete is to think in terms of four movement types, each building something different in capability terms. Getting a promotion to a higher job level is what it means to move up. Lateral moves are when you change job roles at the same level. A diagonal move is when you switch jobs and levels at the same time. Project-based moves are short-term assignments that let workers pick up new skills without having to leave their current position.

• Upward moves remain part of the picture. These are traditional promotions within the same role or function that increase responsibility, authority, and compensation. The lattice does not abandon promotion; it simply stops treating it as the only valid direction.
• Lateral moves build breadth. Shifts to a different role at the same level allow employees to learn new skills, gain broader experience, and expand their professional network. Far from a sideways stall, research suggests these moves matter more than we assume.
• Diagonal moves combine scope and seniority. These combine a lateral shift with added responsibility, helping employees grow into higher-impact roles in a new area. They are often where future leaders are forged.
• Project-based moves keep people growing when a permanent move is not available, building skills without a formal role change.

This is exactly how a lattice reframes a single role. A mid-level operations manager facing a single ladder rung above them might instead see several options: moving up to a senior operations role, moving sideways to supply chain strategy to gain business skills, moving diagonally to regional general management after a stretch assignment, or leading a digital transformation workstream on a six-month project.

These multidirectional moves are the engine of internal mobility, and they connect naturally to mentoring and coaching. Our piece on unlocking career potential through internal mobility explores how transparent pathways and skills mapping turn these options into genuine retention. Crucially, diagonal and project-based moves are also how organisations build the cross-functional perspective that strengthens succession planning.

The Structural Backbone Non-Linear Growth Requires

A lattice is only as good as the structure beneath it. Without that backbone, you risk what one framework bluntly calls "lattice theatre": nice maps, but no actual movement.

Four structural elements make the difference. The first is career architecture and maps that show where roles connect. A lattice sits on top of your job family architecture and compensation structure, linking roles and levels to capabilities, experiences and learning so employees and managers can make informed moves.

The second is transparent criteria for movement. Job architecture, at its core, encompasses job levels, titling conventions, grades, career paths, spans of control, the criteria for career movement and equitable compensation programs based on job value. When the rules are visible, people can plan deliberately rather than guess.

The third is broad pay bands. A common fear about lateral moves is that growth means a pay freeze, but that need not be the case. With broad bands and clear rules, lateral moves can include within-band adjustments when scope or market differs; the key is consistency and transparency, avoiding ad hoc exceptions that erode trust.

The fourth is manager toolkits. Managers are where lattices live or die. Without incentives and norms, talent hoarding persists. Equipping leaders to hold genuine career conversations is essential, and good career conversations start with aligning individual aspirations to organisational needs.

Avoiding the 'Free-For-All' Trap

The flexibility that makes a lattice appealing is also its main risk. In lattices, growth can feel "unstructured," making roles, levels, competencies, and compensation rules harder to navigate. Structure is what keeps a lattice fair rather than chaotic.

Equity deserves particular attention. Lateral moves without pay clarity can erode trust, and unmanaged talent marketplaces can replicate existing biases. The antidote is strong governance: clear movement criteria, transparent pay practices and open access to opportunities. Together, these reduce reliance on informal networks, while structured sponsorship programs help ensure a broader range of employees gain access to career-defining experiences.

Measurement keeps the whole thing honest. It helps to track internal fill rates for critical roles, movement velocity, especially for high-potential and underrepresented talent, time-to-productivity for moves, retention of pivotal talent, and employee perception of career clarity.

Done well, the payoff is shared. The result is greater fairness, improved retention and a foundation for scaling the business, while leaders gain clarity on where critical skills and talent exist across the organisation, allowing them to source from within and better communicate growth opportunities.

The lattice is not a rejection of ambition or upward movement. It is a more honest map of how careers grow now: in several directions at once, each building capability the organisation will need tomorrow. The work for HR, OD and L&D is to make those paths visible, structured and fair, so that growth that doesn't just go up still feels like real progress.
