The Role of the Data Scientist

The Role of the Data Scientist and the Art of Data Science
Gareth Herschel

More Skills are needed!! … we need analytic leaders which blend IT, Data Science and Business.

Analytic Leaders exist to change the business. The way I look at my job and role has changed.

What does it take to become an analytic leader?

How are Data Scientists different? Traditionally we use SW engineers to build an app to solve a problem. A data scientist answers questions that we did not even know we had.

Data Scientist - the sexiest job of the 21st Century

Analytics vs BI - four variations of data analysis - 1) descriptive - monitoring 2) diagnostic - understanding 3) predictive - anticipating 4) prescriptive - controlling

Data scientist cycles between deductive and inductive reasoning. Ultimately towards deductive reasoning.

Business skills of a data scientist:
1) cast salient questions
2) legal, ethics, regulations
3) decision making
4) performance criteria
If you get the question wrong, who cares about the answers?
Data science skills:
1) data exploration
2) which analytics to choose
3) feature engineering

IT Skills:
1) data logistics
2) high performance computing
3) process development

If you put the Data Scientists into the BI Competency Center, you will kill them.

(In Salesforce, the internal IT group reporting into our CIO is called “Business Technology” so you’ll see me use BT to refer to Salesforce IT) I lead the Salesforce Enterprise Architecture team within Business Technology and I’m often asked the following questions: how does Salesforce do Enterprise Architecture? why do you need Enterprise Architecture? how do you shift the conversation to business capabilities? Illuminate — The “How” of Salesforce Enterprise Architecture Let me start with the “HOW” first. Within Sales...

5 Key Components of a Successful Enterprise Architecture Function

  5 Key Components of a Successful Enterprise Architecture Function 5 Key Components of a Successful Enterprise Architecture Function Creating and managing a successful Enterprise Architecture function requires a variety of different hard and soft skills. In addition, each company is different and the Enterprise Architecture function needs to calibrate and align itself to the specific company. However, there are five common features of a successful Enterprise Architecture function that are applicable to all companies. 1. Governance Enterprise Architecture (EA) requires governance, however not in the form of complex documents, forms or processes.  Definitely avoid EA being seen as the policy-enforcement team — people will avoid EA if the perception is that EA is a blocker.  The best governance starts with a simple, recurring dialogue across multiple functions facilitated by EA. I am always amazed at how valuable it is just to get cross-functional teams to  talk . Pick...
