Big & Thick Data as a (tough) approach to transformational projects

To have impact, numbers need stories and vice versa. For business to form a complete picture, they need both Big Data (quantitative information) and Thick Data (qualitative information). Each of them produces different types of insights at varying scales and depths. They may yield interesting synergies and complement each other.

In particular, the tactical decision-making level has a large decision-making gap that can leverage this ‘dual’ approach. On the one hand, analytics-based methods are able to quantify and generalize insights (Big Data); on the other hand, there are empirical approaches that can improve the business perspective and the depth of analysis (Thick data).

We’ve devised four main methods to integrate Thick into Big Data:

  • Raise hypothesis: use Thick Data as a source of inspiration to raise hypothesis that are than tested over the population with Big Data
  • Confirm correlations: check Thick Data insights to confirm correlations that were found through exploratory Big Data analysis
  • Warm-up: plug Thick Data numbers into the warm-up phase of a Big Data project
  • Full connector: start using Thick Data similarly to the Warm-up method, but then continue to use it to keep calibrating the Big Data model

 

Big & Thick Data in the Telco industry with a full connector approach

A great example of a blend of Big & Thick Data is a program launched by a leading Telco provider, with the goal of empowering staff to interact with customers on a personalized level.

The first approach was to combine 79k data variables around customer service and marketing into a single Net Promotor Score (NPS). This model helped move from around 30k NPS attributions per year to scoring the whole customer base with an accuracy of around 80%.

The next step was a sentiment analysis over call center records to move into contextual customer insights, thus refining the NPS score.

Leverage NPS data allowed to differentiate marketing strategy and interaction guidelines between customer groups (detractor vs. passives vs. advocates). For example, to make carefully crafted outbound calls for detractors and use electronic direct marketing (EDM) for advocates. The insights obtained were also essential to ensure there was a clear follow up point to use with each customer.

To engage staff, was built a simple internal portal, with NPS, interaction scripts and key client info. At this point was critical to create strong engagement links with IT.

During the first six months, 50k costumer issues were identified and solved. As a result, the costumer perception (NPS scores) improved.

 

The path towards transformational projects

As we can learn from the previous case study, transformational projects involve cross-functional skills in Thick Data, Data Science and Management.

Effective transformational projects that leverage Big and Thick Data require:

  • a holistic perspective of the problem, covering multiple integrated processes, stakeholders and KPIs
  • a solid methodological approach, to grasp the synergies of both data streams 
  • a sustainable cultural change towards the execution and adoption of such projects to support decision making
