Frequently Asked Questions

What is the difference between a data lake and a data warehouse?

A data warehouse stores structured, filtered data that has already been processed for a specific purpose. It's optimized for fast querying and business intelligence.

A data lake, on the other hand, is a vast pool of raw data in its native format. It's ideal for data scientists and analysts to explore and run experiments on unstructured and semi-structured data before it has been cleaned or organized.

How long does a typical big data implementation take?

The timeline varies significantly based on scope and complexity. A focused Proof of Concept (POC) or pilot project can often deliver value within 3 to 6 months.

A full, enterprise-wide implementation can take 12 to 18 months or more. The key is the phased approach, which allows for iterative value delivery rather than a single, long 'big bang' release.

How do we measure the ROI of a big data project?

ROI is measured against the specific business objectives defined in the strategy phase. It can be calculated through cost savings (e.g., reduced maintenance costs, lower inventory carrying costs), revenue generation (e.g., increased sales from personalization, new data products), and risk reduction (e.g., lower fraud losses, improved compliance).

It's crucial to establish baseline metrics before the project begins to accurately measure the uplift.

What skills are essential for a big data team?

A well-rounded big data team requires a mix of skills, including: Data Architects to design the overall system, Data Engineers to build and maintain data pipelines (ETL/ELT), Data Scientists to build analytical models and run experiments, and Business Analysts to translate business needs into technical requirements and interpret results.

This skills gap is a primary reason many companies opt for a staff augmentation model with specialized PODs.
