Big Data: How does your organization use data for decision making?

How accurate do data-based decisions prove to be?
Sort By:

Hi Kristin Jones, Thanks for the post. I feel next 20 years BIG DATA is going to create great revolution. I have heard from my friend organisation used big data it shows 20% performance improvement compare to others.

I'm waiting for our experts opinion in this regard.

My opinion is that it depends on what data to use, how to process them, how to analyze them and lastly how to use the results to make business decisions. Big storage like Cloud and fast computing allow us to collect and use Big Data but in the end it is how we use it. So my suggestion is reverse engineering, start from what decision you wish to make, and then go backwards to see what data to use. And data is always accurate (well, apart from how you collect it), but business decision is always made by human.

In our world where we use Analytics it is quite accurate. Data by itself will not help you to make decision but further analysis an bringing the right insight is the one which will make the decision accurate.

We use data to make proposals, pricing, investment decisions etc. However, the data collection and analysis is less structured / more ad hoc.

Since we are still trying to make forecasts based on past data, they are not 100% accurate... but probably more accurate than any other method we could use

Hi Kristin,

A very interesting question.

The accuracy of a decision based on the use of "big data" depends on the relevance of the data to the decision being made, and what source of data is being used. For example, using current population statistics, birth rate projections, applications by developers for new subdivisions to be created in a timeframe and existing school population over time might provide a reasonable basis from which to decide where to build the next schools in a municipality, resulting in a decision that might prove itself accurate using future hindsight.

If, on the other hand, only one of these factors was used, or some other factor that bears little relationship to future growth was used, such as overcrowding in current schools with no study of the reason for overcrowding and where the future population will likely reside, the decision made might prove to be very inaccurate.

Accuracy of the data based decision is dependent on the quality of the data,evaluation methods and the expertise of the individual or the the team.To my knowledge, there is no statistical information or a repository available on this item.
