More than ever businesses around the world are recognizing the importance of treating their customers and employees like 'real' people and not "users", "buyers" , "resources"et al. Welcome to the experience economy! It is time everyone understands the importance of experience management and the powerful outcome and business value generated through the insights obtained by combining X-data and O-data.
SAP offers some powerful solutions to enable such an experience economy. SAP Business Technology Platform at the core and center enables this by connecting X-data from Qualtrics and O-data from various SAP Line of Business services together. SAP Analytics cloud is the go-to analytical solution offering on the platform, that can be leveraged for data-driven insights connecting O-Data from Line of Businesses to X-Data from Qualtrics, driving decisions that create "people experiences"
For some time now, SAP Analytics Cloud(SAC) has a standard connector to Qualtrics to fetch and analyze survey responses. Refer to this blog post by rituparna.reddi for more information. The Qualtrics connector makes it easy, efficient and quick to consume Qualtrics survey results in SAC in conjunction with O-Data from other data sources.
In this blog post however, I would discuss the technical details of another approach/use case where I have done the following:
For the sake of better understanding I have come up with a simple use case.
William James, American psychologist said: “The deepest principle of human nature is a craving to be appreciated.”
There are numerous studies out there which prove a lack of appreciation at work is one of the major reasons for employee turnover in a company. It is also believed appreciation has a direct impact on employee productivity. Here is an article which puts this in perspective. What if we can correlate responses on specific questions about employee appreciation, to the number of awards given out and the number of achievements logged in a SuccessFactors system.
Here's a quick architecture diagram:
Let's now look at the details of the prototype:
Here's the approach :
1.a. I have an employee engagement survey of type Employee XM created in Qualtrics.
1.b. I have my HANA service instance up and running and I have created a multi-target application with a HANA DB module . For starters, here is a great developer tutorial you can refer.
Here is a snapshot of how my entity looks like,
1.b. I have used Qualtrics APIs to read the response real-time , every time a response is completed and submitted. This data is written into my table that I have generated in the last step.
Refer to this well documented guide from Qualtrics on how to listen to and retrieve responses real-time
Essentially the steps are as follows :
SuccessFactors provides APIs to access data, enable open integration and allow easy extensions. APIs are of type SOAP/OData. For this prototype I am interested in the oData API for Continuous Performance Management
In this step I have done the following :
2.a Set up the oData Adapter on the HANA Service for Smart Data Integration.
2.b Configure the SuccessFactors System as a remote source system for data replication.
You can follow this blog post to set up the adapter and configure the SuccessFactors system for data replication.
2.c Create virtual tables for the tables of interest. I am interested in getting the User data, Achievements and SpotAward details from the SuccessFactors System.
2.d. Created FlowGraphs to only extract the fields I need and set up replication tasks.
While creating virtual tables from a remote source , you need to ensure the technical user of your HDI container is authorized to access to the remote source. You can take a look at the following links to understand how to do this:
https://blogs.sap.com/2019/02/23/smart-data-integration-cross-container-access-and-the-sap-hana-serv...
As always, one of the best references for anything HANA related is SAP HANA Academy . To understand and create flowgraphs, replication tasks refer the playlist from SAP HANA academy for "how to use SDI in SAP HANA Service"
https://www.youtube.com/playlist?list=PLkzo92owKnVyeoyU0f_6nZVYh4TXb-Z9y
Let's see how this looks in my Web IDE :
SFSF Remote source:
Once I have my access setup from my MTA project to the remote source (as per the steps in the blog/video referenced previously), I can set up my virtual tables.
I have created 3 virtual tables, for User, Achievement and SpotAward.
The flowgraph in my WebIDE . This maps only the fields that I am interested in from the virtual tables on the source side to new tables on the target side.
So now I have my target tables and data , which I can consume in my calculation views
Create calculation views to correlate data from SuccessFactors on how many achievements an employee has logged vs the awards that he has received and map it to how he feels.
Here's the view of the correlated data from the calculation view that compares employee appreciation with actual achievements and awards given out
I have consumed calculation views created in my HANA service on Cloud Foundry through live access in SAC. You can refer to this blog post which collates the information you can use to set up such a connection.
Here is a screenshot of the SAC story which shows X+O Data how in most cases where the employee is demotivated and feels unappreciated, there is a direct relation using quantifiable numbers how many achievements he has had and how many awards were given out. I have set up an auto refresh for the model every 5 seconds
Every time a new survey response is submitted, the new data gets written to HANA, and also through the replication tasks new data from the SF system is also written into HANA. I also have an auto-refresh configured on the SAC story, So, the data that you will see on the SAC dashboard will mostly be latest.
Cheers!
