“I’m an oil man, ladies and gentlemen. I have numerous concerns spread across this state. I have many wells flowing at many thousand barrels per days. I like to think of myself as an oil man”. – Daniel Plainview, There Will Be Blood
Data is the new oil; many people acknowledge that.
However, while no one would imagine trying to drill for oil without the proper expertise, the same is not true when it comes to drilling for insights. All too often, the horror scenario that gets played out across too many organizations is that a manager becomes aware of the importance of data. Said manager then assigns the task to a member of staff who may, or may not, have the skillset or the ability to learn the necessary skills. The staff member with all the best intentions may find great insights (accurate, meaningful), or they may not.
More importantly, organisations jump into the data-dashboard-insights-visualisation field demanding the sexy, shiny final product, without wanting to spend time and money doing the groundwork. It’s like demanding plastics without building refineries and factories that enable petrochemicals to be turned into plastics.
The most unsexy but necessary work associated with data analysis is getting and preparing the data. It is very rare to get data from just one source. Most of the time, data comes from multiple sources, requiring copious amount of time to integrate into a single source. Even when data comes from the one database, it still needs to be checked, cleaned and prepared because missing, corrupted or just incorrect data is all too common. And there is nothing seemingly glamorous about this task – even though cleaning up data so that it’s consistent and reliable – is the foundations of the data analysis structure.
Do you have the skills needed to clean, check and integrate your data? Do you have the patience? Can you explain to management why 90% of the perspiration has been spent on data cleanup? Are you sure, before you dive into data analysis that your input isn’t garbage? Garbage in, garbage out definitely holds true for data analytics. If data isn’t properly cleaned and prepared, the analysis of it can be worthless.
Analytics come in four distinct types: descriptive, diagnostic, predictive, and prescriptive. Each builds off the other. As shown in the figure 1, it is a pyramid with each level supporting the next. Briefly,
A big mistake that companies often make is that they prioritise a single tier. If one of the top tiers is prioritised before securing the bottom tiers, the analytical process becomes unstable. If only descriptive analysis is attempted, then benefits from higher tiers of more insightful analysis is missed.
To take full advantage of the data analytics pyramid, you need the right skillset in your team. You need data analysts. But how do you even know what a good analyst looks like?
If you wouldn’t try to drill for oil without the proper expertise, why drill for insight without the proper data analytics skillset? At P-I, we are experts. We know what to do and we would like to do it for you. We opened this article with a quote from Daniel Day Lewis’s character, Daniel Plainview, from There will be blood about oil. Let us close this article by modifying the quote for data as it applies to us,
