Determine the indicator's value using the following methodology:
1) Decide whether you will collect the data from people who are already using the product (the ‘users’) or from people who are not using it but are aware of the product (the ‘non-users’).
Collecting data from the users will tell you how easy or difficult it is for them to use the product. Such data can help to improve customer service, the development of instruction manuals, the adjustment of marketing interventions as well as how to refine the design of the product.
On the other hand, collecting data from non-users can help you understand their perceptions regarding the product’s ease of use. Due to their lack of experience with the practice, their perceptions might be ‘incorrect’. However, since people are heavily influenced by what they think, understanding these perceptions can help to improve the marketing strategy (e.g. by focusing on addressing common misconceptions).
2) Conduct individual interviews with a representative sample of your target group members:
- First, assess whether a respondent uses the product (see relevant guidance). If you are measuring the perceptions of non-users, asses whether they are aware of the product (only people who are aware of the product should be asked about the ease-of-use).
- Next, assess the respondent’s perception of how easy or difficult it is to use the product (A1 below). Additionally, it is recommended to assess the reasons for her/his opinion (A2 below). In the case of users, it is also recommended to assess what could make it easier to use the product (A3 below).
Q1: “In your opinion, how easy or difficult is it to use [specify the product]? Would you say that it is very easy, quite easy, a bit difficult or very difficult to use it?”
A1: very easy; quite easy; a bit difficult; very difficult; does not know.
(the following questions are not mandatory but are highly recommended; ask them only if the previous answer is ‘a bit difficult’ or ‘very difficult’)
Q2: “Why do you think that it is difficult to use the product?”
A2: provide pre-defined answers + option ‘other – specify: ………………’
Q3: “What would make it easier for you to use this product?”
A3: provide pre-defined answers + option ‘other – specify: ………………’
Note:
- It is very important that you keep probing: “What else would make it easier?”; “Anything else?”
To calculate the indicator’s value:
- count the number of respondents who stated that the product is either very easy or quite easy;
- divide this by the total number of respondents (excluding those who did not know)
- multiply the result by 100 to convert it to a percentage
