Standard : Internal Mobility and Progression Rate

Description

Internal Mobility and Progression Rate tracks how frequently engineers move into new roles, grow within their teams, or take on broader responsibilities within the organisation. It is a key signal of talent development, career support, and a culture of learning and recognition.

This metric helps organisations evaluate how effectively they are investing in their people, promoting from within, and enabling engineers to evolve with changing business needs.

How to Use

What to Measure

  • Number of engineers who moved into a new role, discipline, or level over a set period (e.g. quarter or year).
  • Include both lateral moves (e.g. backend to platform team) and vertical promotions (e.g. Engineer to Senior Engineer).

Formula

Internal Mobility Rate =
(Number of internal moves ÷ Total engineering headcount) × 100

Progression Rate =
(Number of role level advancements ÷ Total engineering headcount) × 100

Segment by:

  • Role level (e.g. junior, senior, lead)
  • Time in role or tenure
  • Department or capability area

Instrumentation Tips

  • Use HRIS or career frameworks to track role changes and promotions.
  • Distinguish between planned mobility and reactive movement due to organisational churn.
  • Track progression against DEI targets if applicable.

Why It Matters

  • Enables growth: Engineers stay longer when they see progression opportunities.
  • Promotes retention: Employees are more likely to stay when they can grow internally.
  • Builds versatility: Internal moves increase cross-domain expertise and adaptability.
  • Inspires others: Visibility of career movement builds momentum and motivation.

Best Practices

  • Publish career frameworks with clear criteria for advancement.
  • Create visible internal job boards or secondment opportunities.
  • Pair engineers with mentors or sponsors to support mobility.
  • Hold regular progression check-ins aligned with development goals.

Common Pitfalls

  • Lack of clarity around what constitutes progression or career movement.
  • Biased or inconsistent application of promotion standards.
  • Hoarding of talent within teams due to short-term delivery concerns.
  • Failure to support lateral moves as valuable progression.

Signals of Success

  • Progression is seen across diverse teams and backgrounds.
  • Career conversations are regular, structured, and inclusive.
  • Teams report high clarity on how to grow and what’s expected.
  • Internal hiring is prioritised before going to external market.
