What it is

CES builds on the finding that loyalty depends more on how much effort it takes to get something done than on delight. The less effort, the more likely people come back.

Ask right after a specific step is done, such as exporting a report or inviting a colleague, not about the product in general.

How it is calculated

CES = the mean of answers 1 to 7. In addition, the share who agree (5 to 7).

How to read the result

  • Tack places the mean in bands: from 5.8 the step is easy, from 5.2 average, below 4.6 it costs people needless effort.
  • Compare steps with each other: fix the one with the lowest CES first.

When to use it

  • After a specific step in the app is done.
  • After reworking a feature, to confirm it really is easier.

Frequently asked questions

What is the difference between CES and SEQ?

Both measure ease. SEQ asks after a task in a test how difficult it was. CES asks real users after a step in the product whether it was easy.

Is CES on a 1 to 5 or 1 to 7 scale?

Both are used. Tack uses the seven-point one, which tells small differences apart better. Do not compare results from different scales.
