People Analytics - CRIS-DM Simplified

Actualizado: 2 nov 2022

As in other areas of data science, extracting value from data in people analytics also has a process with well-defined stages.

The basic process of any solution is compiling and incorporating

an organization’s HR knowledge to learn from using computational learning algorithms, data science,

and reasoning. Finally, faced with a demand for information, you

have to be able to respond (prediction, classification, recommendation)

by justifying the results with objective metrics.

The CRISP-DM Methodology was born in the 1990s. CRISP-DM

(Cross Industry Standard Process for Data Mining) provides a

the standardized description of the life cycle of a standard data analysis

the project, similar to how it’s done in software engineering with

software development life cycle models.

In our people analytics methodology, we generally simplify this

process from six phases to four steps. But, essentially, we adhere to

the model consolidated in the 1990s.




Step 1: Define HR Needs.

This initial phase focuses on understanding project objectives. In

people analytics, we think about this business need by asking a

question.

Have a look at this quote by John Bersin25 that demonstrates why

you need to question ”what for?”:


Step 2: Study and Understand the Data.

The data comprehension phase begins with the initial data collection

and continues with the activities that allow you to familiarize

yourself with the data, identify quality problems and discover preliminary

knowledge about the data. And then you may find interesting subsets

to form hypotheses about the hidden information.


Step 3: Modeling

The analysis process consists of executing Data Analytics techniques

to identify patterns that represent the relationship between

the data, applying algorithms to the variables under analysis, such

as regressions, k-nearest neighbors, neural networks, decision trees,

Bayesian networks, etc.


Step 4: Evaluate and Deploy. Action

The last step is to transform the generated patterns into concrete

action plans that can help the people in human resources to achieve

their goals.
