Evidence-based levelling: growth not naming but proving

When an organisation grows, more teams, more titles and more layers are added. Then it becomes important to clarify exactly what each level means. In this blog, you will read how to work with evidence rather than opinions so that promotions feel fairer and cause less discussion.

Where it often goes wrong

Once there is growth, a few things happen at once:

• additional teams and titles will be added

• decision-making around promotions slows down

• expectations per level are not clear

People hear words like “medior”, “senior” or “lead” but no one can explain exactly what the difference is in behaviour and results.

Consequence:

• promotions sometimes feel arbitrary

• conversations are about interpretation rather than impact

• people drop out or get stuck

Without an evidence-based system, the whole ‘leveling’ narrative quickly loses credibility.

Make evidence leading

The basis of evidence-based ‘leveling’ consists of two components: an evidence library and proof assignments.

Evidence library

For each role and level, record 4 to 6 pieces of evidence. These are concrete examples of work that show someone is at that level. Think about:

• a customer case with measurable results

• a delivery that reduced a risk

• a process improvement that shortened lead time

• a project where multiple teams are well included

Use real examples from your own organisation. The more recognisable the better.

Proof assignments

Then formulate short tasks that someone can perform within the current role to show the next level. For example:

• “lead one cross team kickoff with a risk overview and a plan for the first four weeks”

• “Reduce the time to hire for profile X by 20 per cent and document how you did it”

Thus, growth does not become something vague in a conversation report but visible in daily work.

Reward without title inflation

Create salary bands by level, not by title. That gives peace of mind and clarity.

Practical:

• create one page per pay band

• For each band, describe the decision criteria and 2 to 3 concrete examples

• ensure that title changes only occur when behaviour and outcome belong to the level

Reward then follows from evidence, not from the need to “give something” to someone.

If you deliberately deviate from the line, briefly note why. This protects the system from arbitrariness and helps make criteria sharper.

Calibrate with examples, not opinions

Calibration is nothing more than checking together whether you mean the same thing by “junior”, “medior”, “senior” or “lead”.

Composition

Put managers and seniors together at the table. Everyone brings two cases with:

• context

• data

• description of impact

Working form

For each case, you answer three questions:

• what was the purpose

• what has demonstrably changed

• what makes this appropriate for this level

So you always link behaviour to results, not impression or favour factor.

Outcome

On each case:

• confirm the current level

• appoint a growth gap

• Or formulate a proof assignment for the next period

That way, you turn calibration into a learning moment rather than a political conversation.

---

Display the growth path visibly

For each role, create a simple roadmap with two columns: “now” and “next step”.

For each step, you show:

• which proof task belongs to it

• which example case serves as a reference

• who is available as a mentor

Employees can then see at a glance:

• which examples count

• which steps are logical

• where they can find help

Thus, promotion does not follow from potential alone but from evidence that someone is already delivering at the next level today.

---

Measuring what matters

To see if evidence-based ‘leveling’ works, you can follow a few things:

• promotion lead time by level
  Number of months between first piece of evidence and final decision

• retention by level
  Do people stay longer when the criteria are clear

• internal mobility
  Percentage of colleagues growing horizontally or diagonally within 12 months

• quality of calibration
  Number of cases per session that include data and concrete results, not just opinions

These figures show whether the system makes the organisation stronger and not just tighter.

Common mistakes and how to avoid them

A few pitfalls recur frequently:

• too much competence language
  Write in examples, not abstract terms.

• no owner
  Designate a library owner for each role to collect and update examples.

• thinking in projects
  Don't think of evidence-based ‘leveling’ as a trajectory that is ever “finished”. It belongs in your regular work routine.

• titles as band-aids
  Use rewards and assignments to value growth, not single titles without appropriate behaviour.

Start small, prove fast

You don't have to revamp the entire organisation right away. A workable first step:

1. Choose one group of roles where there is most friction around promotion now.

2. Write down 4 pieces of evidence for each level, with examples from the past 6 months.

3. Plan an initial calibration session with three cases and record the decision for each person in one paragraph.

4. Create a simple roadmap and put it on your internal home page with a link to the proof assignments.

After two months, evaluate retention, internal mobility and promotion time. This will allow you to quickly see whether evidence-based ‘leveling’ is working in your context and where you need to make adjustments.
