We also have data on the following:
-
License - is a description of what license the customer has, where the data would either
be “Freeware” or “Premium.” You believe that premium software customers should buy
more services.
-
Size - is a description of the size of the customer by turnover. You categorize this description
into three broad levels, namely “Small,” “Medium,” or “Big” based on certain thresholds.
Your initial belief is that bigger customers will buy more services.
-
Trust - refers to the trust the customer has in your product and company. You have measured
trust through four questions in an online survey that you sent to the key account
holder at the client. Various areas of management theory, past research and your experience
suggests greater trust may lead to greater sales, all else being equal.
-
Customer satisfaction - is also seen as important, and is also a core concept in previous theories and
studies. You also measure satisfaction through four questions in a paper-based customer
survey. Again, various areas of theory, research and your experience suggests greater
satisfaction may lead to greater sales, all else being equal.
-
Enquiries refers to the average number of enquiries about the core software product logged with
the call center or online help by customers, per month, since starting use of the
product. This data is provided by your in-house customer relationship management (CRM)
data system. You believe that more enquiries may associate with higher sales, because
customers who make more queries are more engaged with the software and perhaps more
needful of consulting and/or training to help them with their requirements.
Figure 1.1 First lines of initial dataset shows the first twenty rows of an initial dataset, as it might appear in a data sheet
(we will use this data in SAS analyses throughout the book). Here, we have limited
the data to customers who have bought services.
Notes: This table is not all the data: I have omitted most of the Trust and Satisfaction
variables to enable the table to fit the page. You will see the whole dataset when
we open the SAS data file later in the text. Note also that there are mistakes in
the data that we will detect and clean later.
Because sales is your key focus in this study, these other variables will mostly be
seen as issues that can help explain or predict sales.
There are other issues that the case will consider, such as:
-
Analyzing the customer base by types of licenses and sizes
-
Relating the other variables (for instance, does higher satisfaction lead to higher
trust?)
-
Focusing on differences in core variables (like sales) between sizes and licenses.
