Hi all

The data I need help with is to analyse the data around a trial of a new way of running customer services where two initiatives were trialled where customers were given a telephone call proactively by our company to see if they had any issues that needed resolving with the aim of resolving them over the phone if possible (all the customers called or not called successfully = 106, contacted successfully by telephone only (89) OR contacted successfully by telephone and also given a free home service call (17) - and there were 23 who the customer service officers were unable to get in contact with when they called:

106 is the 89 and the 17 added together which delivers the 106 total - the number for those who were called but no one was in is essentially for information only (I think) - although they kind of act as a small control group ie they didn't have a contact so it would show how likely they were to need to call back if no one proactively phones them. The 106 is therefore the number of customers who were successfully contacted 89 of which had just a phone call and 17 had a phone call and a home service call.

All these refer to totalled cells elsewhere where I've counted up the different types of contact as a % of the 106. All these refer to totalled cells elsewhere where I've counted up the different types of contact as a % of the 17, 89 or 23.

The questions I want to answer (and where my mind is going a bit blank :confused:!) is around how to identify which method of contact was the most and least successful to meet this aim: for all customers contacted proactively by us to be able to compare whether not being contacted at all (Not successfully contacted(?)) or contacted by telephone only (Contacted by telephone only) or had a call and a home visit (Had home visit) which was the most and least successful method in preventing the customer from having to call back any more (Customers who did not have to call us back after our call).

As above but for those who had to call us back once and those who had to call us back two or more times what were the results based on the three different contact methods - did customers call back less, the same or more under the different contact methods.

The company wants to figure out if asking staff to follow this methodology had a significant enough effect on preventing customers having to call back that it's wise to continue it as an ongoing operational model, or if the effect wasn't much different to customers who weren't contacted at all - does it reduce customers having to call back or is it not much better than just letting them call themselves if they need to? Was the most important thing to give them a home service call (was just a phone call ineffective?).

Crikey I hope that's clear (and not as mud!) and any help really appreciated.
 

Excel Facts

Format cells as time
Select range and press Ctrl+Shift+2 to format cells as time. (Shift 2 is the @ sign).
do you phone the customers at random, and of those who have an issue do you - say - set up a home visit for a quarter of them, ???

what may be significant is the % needing second and third calls to resolve the situation.

maybe you could do Pareto analysis on the reasons for dissatisfaction - excel is very good for that....

Hi Oldbrewer.

The absolute crux is not having them needing to come back to us at all - our telephone call on its own or our telephone call and home service call together are meant to achieve that aim.

We select customers based on the ones we hope will not need to come back to us the most - so in this case they happen to be the more elderly/vulnerable customers and that's the basis for selection.

For ALL customers successfully contacted on the phone if the phone call doesn't resolve the issue then for all those where the issue wasn't resolved, all of them would then get a home service call.

I'm not sure if what I've done so far is correct and usable to answer what I need to answer.

I'm not sure I'd know how to set out the information in order for it to be Paretoable?

still trying to understand the basic question - are all the customers who are phoned people who "have a problem" and have reported it to you ? And you are phoning them BACK to resolve the issue ?

No. They are phoned because they fall within the group 'elderly customers' who we want to take special care of. So no there is no guarantee whether they will have an issue or won't have an issue. If they do have an issue they may not have reported it so we only learn about it when we call. We only conduct the call once.
