As an organization grows, it changes rapidly… So naturally the work and roles are in constant flux. Specific roles and responsibilities at a 50-person company often have a large breadth and range of seniority. For example, a given role could require work that’s described as a Level 2, as well as work that’s described as a Level 4. At a larger organization one role is likely to fit solely in a Level 2.
As an organization grows and matures, the work and corresponding roles deepen and become more specialized. As a result, the level descriptions require additional dimensions and specificity. Additionally, it is common to add layers of management as growing teams hire more experienced leaders.
