    • The Reality of Big Data
    • #beltech2014
    • #1 – What problem are you trying to solve?
    • Most of SME’s problems aren’t Big Data, it’s just data.
    • Without a question you are wasting your time.
    • #2 – Data will need cleaning
    • Roughly 80% of your data project will be getting the data into shape before processing.
    • Btiany Spears
    • #3 – Hadoop, on it’s own, will NOT give you the answers.
    • #3 – Hadoop, on it’s own, will NOT give you the answers. (The Big Data version of “putting it in the cloud”)
    • If anyone says, “will Hadoop just give us the answers” or “put it in the cloud”, do this….
    • Spit on one, or both, of their feet and bite your thumb while shouting: “The fig of Spain!”.
    • #4 – Do you actually need Hadoop?
    • A well crafted algorithm may give you more benefit.
    • It’s about knowing the right questions.
    • And refining and refining and refining…..
    • The first run won't work at all The second only makes you wonder The third will have you on your knees.....
    • #5 – Data changes
    • …especially when you don’t own it.
    • If you feel your data has value then retain it.
    • If your data passes over the “creepy line” then definitely retain it.
    • #6 – Skills are in short supply
    • Work with what you have.
    • Play with data, it’s the best way to learn.
    • Collaborate with others to fill the skills gaps.
