Scrolling through the images, it's hard to imagine someone greenlighting these ideas. David Pereira, the Head of Product Management at Virtual Identity, thinks it often happens when development gets too 'dry.'

"Products are built for people. Yet, many people lead product innovation through numbers, which means people become numbers [and] behaviors become data points," Pereira wrote. "Therefore, misunderstanding of the audience is inevitable because of too many false assumptions. Product teams that don't challenge the data become blind and build useless products."

The product manager pointed out that there's nothing wrong with being data-driven, it's just that teams need to understand when to apply numbers and when to stay away from them.

"Data will bring us insight from the past, showing details about customer behavior... However, we should not overlook the power of observation," Pereira said. "Once we observe real people using real products, insights will come to us [naturally], and [we'll be able to] understand how people use the [said] product [way better]."

Pereira is a big fan of prototyping. "I prefer accepting that [I] don't know enough; at best, [I] have a set of assumptions, which need validation as fast as possible. That's my approach for [all] ideas."

In his opinion, the Lean Startup method created by American entrepreneur Eric Ries is an excellent way of building products that solve real problems.

However, I guess it's either we have less useless stuff or more content on r/OfCourseThatsAthing. How can we possibly make this choice?!
