one direction up · or many directions across · ladder leaks IC talent
Career architecture: lattice vs ladder
A pure ladder forces “up or out.” Strong individual contributors who don\'t want to manage leave the moment they hit the IC ceiling. Modern career architecture solves this with three things — and the exam reliably tests all three together.
model · ladder
One direction
Up or out. Strong ICs forced to manage to advance. Talent leaks at the ceiling — engineering principals leave to be staff engineers somewhere else.
model · lattice
Many directions
Lateral, diagonal, even downward moves. IC and management both lead to the summit. Bands mark altitude regardless of path.
Three components, all required
component 01 · bands
4–7 levels with standardized leveling guides.
Each band has comp range, expected scope, and impact criteria. Without bands, every promotion creates a new title and the org\'s comp architecture fragments inside two years.
component 02 · lattice mobility
Cross-function, cross-BU, sometimes cross-level moves.
The model fails when managers hoard talent. Senior HR builds release-incentives — manager scorecards that reward mobility-out, not just retention-in.
component 03 · dual track
IC summit and management summit, equally compensated at the top.
Distinguished engineer = director comp. Principal scientist = VP comp. Without that equivalence, the dual track is theater — and the strongest ICs eventually leave because the math says manage or move on.
Exam Traps
Ladder ≠ lattice
Ladders only go up. Lattices include lateral, downward, and diagonal moves. Senior HR designs lattices for modern careers.
Bands prevent title inflation
Without career bands, every promote creates a new title. Senior HR uses leveling to control title proliferation.
Dual-career tracks for IC vs management
Strong individual contributors should not need to manage to advance. Senior HR designs IC track + management track.
Mobility requires manager support
Lattice fails when managers hoard talent. Senior HR builds incentives for releasing talent to other teams.
Ladder leaks talent
Pure ladder forces "up or out." Strong individual contributors leave when they can't advance technically. Lattice retains both paths.
Lattice + bands + dual track
Modern career architecture combines all three. Bands set leveling. Lattice allows movement. Dual track supports IC + leader paths.
Multiple paths up, sideways, and across. Not just one ladder.
Career bands assign altitude regardless of path.
IC track or management track. Lateral moves between functions.
Strong managers release talent to other walls. Hoarders block careers.
IC summit. Management summit. Both valued, both rewarded equally at top.
