The Big Data Revolution is Expensive. Re-Evolving Your Data is Not.

Here’s Why

Part 2 – Engineers’ Perspective

Siraj Tahir@sirajt

• It takes a revolution to make the solution

• Too much confusion, so much frustration

• It takes a re-evolution to make the solution

• Too (avoid) much confusion, (and) so much frustration

Part 1 – Key Points

• Avoid Expensive Mistakes• Leverage Existing Data• Focus on Objectives not on Objects• Enhance & Enrich with BigData• Understand Limitations• Create Insight• Generate Actionable intelligence

Types of BigData

• Enterprise and Business Operation Data

• Customer and Consumer Data

• Civil Engineering & Citizen Services Data

(from Three kinds of Big Data by Alistair Croll, 2012)

Is BigData New Concept for Engineers?

Not entirely a new concept …

• Environmental Models– Weather & Climate, Hydrological, Hydraulic, etc

• Construction Management Models– Buildings, Roads, Bridges, Tunnels, etc

• Utility service provision models – Water, Electricity, Gas, etc

(Joseph Stretha, Iowa State University )

If its not new…

How have we dealt with it in the past?

So what is new?

Big Data

Variety

Volume

Complexity

Velocity

Why Use it?

• Reduce Uncertainty

• Improve Operational Intelligence

• Increase Efficiency

• Ensure Compliance

• And mostly….. Because there is no other option!
