Selecting the NPS-type scale of 0-10 has many benefits compared to e.g. smileys.
Our scale of 0-10 was selected, because it is better in finding the areas what to develop within your services. NPS-type calculations react to change faster than any average scale. This helps to recognise positive and negative changes faster.
It also makes it possible for you to compare the results to NPS. Many companies are measuring their consumer or business to business services with this scale. Now when the metrics are the same, your stakeholders are able to discuss with their own business with numbers/results that can be compared to their own on high-level.
We believe that some times smilies are selected to get more responses. We have proven that high response rate is possible also with NPS-scale.
The Net Promoter Score (NPS) is an index ranging from -100 to 100.
HappySignals also has the average score available, if needed.
