There are as many product supervisor hats as there are product phases, and there are as many puzzles as there are product challenges. One most important puzzle is knowing causation vs. correlation.
Greedy these two ideas is essential for venture managers to grasp how sure options, stakeholders, or processes play a task within the success of the general product.
At present, PMs have a number of instruments at their disposal to assemble information. Whereas this abundance of data is welcome, PMs ought to stay as skeptical and cautious as any detective value its salt. “Warning” right here implies gathering standards that may be utilized when your instincts counsel sure insights is likely to be too good to be true (or too unhealthy to be believed!)
Right here, you’ll study all about causation, correlation, and the way they’re related. Additionally, you will perceive their variations, the advantages you would possibly achieve from correct causation, and the way in which the strategy saves time and sources for PMs.

Defining causation and correlation
In short, causation implies a selected relationship the place one particular factor or course of leads to one other particular factor or course of. Suppose how the elevator comes down once you press the precise button, or how one can burn your tongue if you’re impatient and drink your espresso too early! Right here, trigger and impact are straightforward to acquire, as in 2+2=4.
Definitely, the aim of recent analysis (for the reason that inception of the scientific technique) is to ascertain barely extra advanced causations. For instance, how does warmth evaporate water? Why do snow avalanches happen? How do seeds flip into totally shaped crops?
Completely different professionals concentrate on creating a set of kind of mounted approaches and instruments that may be replicated and examined repeatedly by completely different groups. If sufficient repetitions return the identical outcomes, then one can affirm that the proposed rationalization is correct, until a extra stable motive emerges, after all!
Compared to causation, correlation is a less complicated affair. Correlations refer to 2 processes that, a minimum of on the floor, are occurring on the similar time. Once more, water heated strongly sufficient will evaporate. Each the heating and the vapor happen concurrently. Nevertheless, and that is key, we’re not involved with explaining; the noticed relationship is all that we’ve got.
In some ways, that is how people developed prescientific information. Early farmers, for instance, would observe that seeds planted and watered in a sure means would develop to turn into crops.
That is, after all, the primary means that causation and correlation are related: they’re each used as explanatory units (although they maintain completely different weights, as you will note under).
Moreover, correlations are sometimes the start line for exploring attainable causations. It’s regular to imagine some type of relationship once you see occasions repeatedly occur collectively.
That mentioned, the next level is the crux of the matter: not each correlation will equal causation.
Head’s up product managers, correlation doesn’t equal causation
Sure, easy causal relationships are straightforward sufficient to identify if you find yourself a product supervisor, and sure, they usually seem as correlations. For example, if the app to your product introduces responsive design, your consumption of cellular and pill customers ought to improve.
Nevertheless, many different connections are more durable to clarify, and a few apparently tightly-knit developments could be completely misguided.
Let’s return to basic examples. Local weather change is a confirmed problem that took a long time to ascertain within the public consciousness. Hundreds of scientists in dozens of nations have been working collectively to establish and isolate an important causes.
One of the crucial noticed parallels is the rise in CO2 ranges within the ambiance, and the rise in international common temperatures, with corresponding results on climate techniques. Thus far so good — an initially fascinating correlation has been confirmed repeatedly, each in labs and checks as distant as house.
There’s, nevertheless, one other correlation that many scientists will not be actually inquisitive about pursuing. And this isn’t as a result of they’re afraid that it’ll problem local weather change science, it’s truly fairly the other.
That is the inverse relationship between the variety of pirates working the world over and the rise in temperature ranges. You learn that proper. As pirates have disappeared from the scene, international temperatures have risen.
Ought to we carry again pirates to resolve this international problem?
The plain reply is not any.
What we see above is a baseless or uncertain correlation. These are prevalent in enterprise, however they’re more durable to disprove when making quick-fire product choices. Listed here are some examples:
- The Californian solar is especially useful for digital corporations (the trendy tech sector might need emerged in Silicon Valley, however it has unfold all over the world)
- The extra superheroes a film has, the extra profitable it is going to be (there are lots of worthwhile superhero motion pictures, however some have been huge flops)
- The variety of customers and profitability go hand-in-hand (Twitter, with tens of millions of customers, has barely turned a revenue; whereas smaller social websites have)
- As extra persons are related to the Web, there’s an elevated expectation that content material and knowledge needs to be free (in reality, there are extra paid digital subscribers immediately than at any level within the historical past of the Web)
Please notice: it is likely to be that these noticed relationships grow to be true, even when some counterexamples are listed. Nevertheless, there’s a excessive chance that they aren’t sound sufficient to offer enterprise steerage.
In the event you lack a longtime strategy to figuring out causation, you’ll by no means know the true explanation why so many corporations in California are profitable; superhero motion pictures are so widespread; monetization and recognition don’t at all times go collectively, and persons are more and more spending extra money on on-line providers.
Subsequent, we’ll have a look at how one can leverage causation at completely different product phases.
Figuring out constructive causations in product administration
Firstly, notice that the time period “constructive” right here doesn’t indicate useful or good. We’re referring to an noticed relationship that’s been confirmed to function causally after isolating all attainable options.
Now, we’ll go over the method of figuring out constructive correlations in product administration all through a product’s life cycle:
- Researching the product
- The planning part
- Implementing product testing
- Monitoring the product’s growth and success
Researching the product
At this stage, there are sometimes no precise merchandise or options prepared for testing, however you is likely to be exploring a selected market phase or particular viewers.
Your desk and area analysis ought to purpose to substantiate or disconfirm noticed correlations, such because the connection between your competitor’s bodily retailer technique and digital visitors. Does storefront presence actually contribute to on-line orders? Or is that this an expense that your extra nimble venture might keep away from to scale up shortly?
The planning part
It’s best to make an effort to embed a causal perspective throughout your product groups when within the planning part. In the event you handle an expert operation, tech and non-tech folks can have turn into used to attaching proof to requests and value determinations.
With out correct instruction, they could be merely using improperly assessed correlations. Be certain to clarify the distinction throughout your groups to keep away from false begins.
Implementing product testing
Right here is the place testing turns into viable. You might be seemingly acquainted with A/B testing. When unsure, most growth, advertising and marketing, and different options give you the possibility of attempting out two or extra product varieties to grasp which one is extra profitable along with your target market.
You are able to do this kind of blindly, with out taking note of causal implications, however then you’re lacking out on extra worth. In the event you can establish why precisely one model of a product or function carried out higher, the perception is much more essential.
Monitoring the product’s growth and success
Proof-based, everlasting growth is essential for managing digital merchandise. However your suggestions will probably be much more highly effective should you take note of causal elements.
Why is it that my customers disliked the most recent launch: technical points, or unhealthy design? Why was that function so tough to implement: lack of staff cohesion, sources, or administration? How can we clarify our fast improve in gentle of our stagnating person development? Why ought to the sundown interval for this legacy function start now, and never additional into the long run?
These are a few of the intriguing questions you must search solutions to. Neglect trial and error, embrace your detective hat and the scientific technique that helps you establish causation.
Keep away from losing time and sources on baseless correlations
You would possibly assume that embedding yet one more perspective in your already convoluted growth course of is just too pricey. Nevertheless, causation can save loads of money and time.
For instance, self-importance metrics are a plague of digital and different industries. That’s, feeling proud a few specific piece of knowledge that truly has little or no connection to your small business efficiency. This occurs lots when new platforms gloat about their fast development and recognition, with out actually contemplating whether or not there’s a sustainable technique to retain customers or to show engagement in direction of worthwhile providers.
Baseless correlations are comparable, as they will make you waste time and sources. However the easy explanatory enchantment that a few of these unexplored observations have could make them much more harmful.
It’s nearly like being within the on line casino, betting on a quantity and a coloration for some random motive and making some winnings for some time. Nevertheless, as , the home at all times wins. In that case, you higher have a very good causal rationalization of why you failed to make sure which you could decide your self up and check out once more.
Conclusion
On this article, we talked in regards to the significance of understanding causation vs. correlation in product administration. It’s straightforward to fall into the lure of assuming a correlation is causation, so might this information be a reminder to at all times do your due diligence.
