Answer as always……it depends.

It depends on your customer and their relationship with your organisation. It depends on what type of service interaction you are looking to evaluate. It depends on the scale of the programme you are looking to develop in terms of volume of surveys. It depends on the depth and frequency of reporting the organisation requires. And so on and so on……oh yes and what budget you have.

But what are the options?

Post: send out a paper based self-completion questionnaire to customers.

Email: send out an email to customers that directs them to an online based survey.

SMS: send out questions and invitations to take part in research via SMS.

Outbound IVR: contact customers using an automated dialling and IVR system.

Post call IVR: direct customers to an IVR based survey immediately after a customer service interaction.

Outbound agent telephone survey (Computer Assisted Telephone Interviews - CATI): market research interviewers contact customers to complete a telephone based survey.

There is also any number of multi-methodological solutions too. For example, phone based agents inviting customers to complete an online survey or sending customers an invitation to an online survey via SMS.

At the end of the day each of these approaches should be considered for any customer feedback programme. Fifth Quadrant uses more than one of these approaches but it is always the client’s objectives and situation that drives our recommendation. To help you navigate this challenge, over the next few blogs I will go into a bit more detail about the advantages and disadvantages of each. Starting with outbound agent telephone surveys.

Using this approach ensures high quality and standards throughout the interviewing process. This methodology promotes quality data collection and ensures that data is safely and effectively stored for immediate analysis and future reference. I will admit I am a bit bias towards this methodology as we do run our own customer satisfaction outbound call centre in house and we have used this methodology quite extensively.

One of the big advantages of a CATI methodology is that it can deliver very high response rates, often in the 30%-40% range which is much higher than other methodologies. From a data quality and quota management perspective it is much easy to maintain control. For example, if a survey is of poor quality, that survey can be immediately flagged and replaced. With other methods you have to wait until the fieldwork is complete before reviewing the data quality. In addition if you have skilled interviewers you can often gather a much greater depth of understanding from open ended questions.

From a negative perspective, the biggest issue is cost. CATI can be more expensive than other methodologies and hence may result in a lower sample size given a particular budget or higher costs for a similar sample size. As a CATI methodology may be based on a smaller sample, the depth and frequency of reporting may be less when compared to other methodologies.

One of the most important elements to take into consideration when choosing an appropriate methodology is the scope, breadth and depth of the information that is required. CATI is great for collecting a much more detailed level of information compared to some of the automated approaches. With a CATI survey you can probably keep the customer involved for up to 15 minutes which allows for much more information to be collected. The key trade off here is volume of data versus depth of data.

Next time……..SMS.
