Tier
A tier corresponds to a threshold in a progression mechanism. It can trigger a change of status, a benefit, or a reward. The reference period and the handling of multiple transitions must be specified. Well-presented thresholds make the next objective understandable for the participant.
A concrete example
A threshold of €5,000 and then a second of €10,000 unlock different benefits in a hypothetical example. The participant can see the remaining amount to be reached.
A point to consider
A threshold is not a status: it can trigger a one-time bonus. Specify whether bonuses are cumulative and how to handle returns.
Verify the accessibility and cost of thresholds
Project the distribution of participants around each threshold based on relevant historical data. A threshold that is too far apart can be discouraging; several thresholds close together can concentrate the budget without changing behavior. Document what happens when a single transaction crosses several thresholds and when a return brings the cumulative total back down. The displayed rule and the calculation must yield the same result.
Questions to ask your team
- What proportion of the public can reasonably reach each threshold?
- Does the budget take into account multiple entries?
