6 Product Development Mistakes That Kill Great Ideas
October 6, 2026
And how to avoid them before your next big launch
We’ve all had a time in our careers where we had a strong instinct about something and built something around it – only to watch it fall flat in the market.
We end up telling ourselves our instinct was wrong.
But Mark Pincus sees it differently. And he would know: he’s the cofounder of Zynga, which dominated the mobile gaming world in the early social internet era.
Just last week, I released the fascinating conversation he and I had on How Leaders Lead. In it, he said something every leader needs to hear:
“Your instincts are right, but your ideas are wrong.”
In other words: there are a lot of strategic pitfalls that can prevent a great instinct from becoming a successful product.
Before you build your next big thing, here are six mistakes you need to avoid.
1. You’re unclear about what you’re building
We’ve all had that sinking feeling near the end of a project where we realize nobody on the team is quite sure what they’re building anymore … or why it matters.
That’s why, at Amazon, before they write a single line of code on a new product, they write two documents: a press release and a FAQ.
As CEO Andy Jassy explained to me on How Leaders Lead, the press release forces the team to articulate what they’re building and why anyone would care. The FAQ helps them think through the hard details upfront. Together, they create clarity for everyone involved.
Too often, what starts as a good instinct ends up drifting and getting diluted once the work begins. By using Amazon’s “working backward” documents, you can avoid that mistake and make sure what you’re building really matches the original instinct.

2. You didn’t get buy-in from your team
I learned this one the hard way.
In my PepsiCo days, I launched Crystal Pepsi on the instinct that people wanted a clear cola. But our franchise bottlers kept telling me it didn’t taste enough like Pepsi.
I didn’t listen. I thought they just didn’t get it.
But as you probably know, Crystal Pepsi didn’t last. It launched with a bang but died fast as customers tried it once and didn’t come back for more.
Crystal Pepsi might have been the right instinct. But if you don’t allow your instinct to be shaped by your team, you’ll miss out on key insights that could make or break it. Plus, just like the bottlers in my story, people who aren’t involved in something don’t have a stake in making it work.
So when your big idea raises objections, your first question shouldn’t be “how do I get past this?” It should be “what if they’re right?”
3. You have no channel for customer input
It seems obvious to say that you should involve your customers in your product development. Yet you’d be surprised how often companies launch products first, then ask for feedback later.
By then, it’s almost always too late to implement without a lot of time and expense.
I love how Aneel Bhusri and his team at Workday build customer input right into the product development process.
When Workday was developing a new product called Accounting Center, they assembled a group of eight customers from different industries to help define what they needed. Those customers shaped the product right from the start.
It may feel like an extra step, but make customer input a core part of the process, not an afterthought. What they tell you before you build is worth ten times more than what they share afterward.

4. You’re trying to change too much at once
When your instinct is strong, the temptation is to swing big. But the best product builders know that innovation works best in small doses.
Mark Pincus often sees entrepreneurs who try to change too much at once. In our conversation, he told a story about a friend who launched a robotic restaurant with a health-forward menu. Either one of those elements on its own might have worked. But both together gave customers too many reasons to hesitate, and the concept failed.
Don’t let too many variables drag down a solid idea. Start with what’s already proven, make it better in one obvious way, then add one new idea that’s uniquely yours.
5. You don’t have a simple way of explaining it
It doesn’t matter how great your product is if people can’t quickly understand what it is and why it matters.
Ben Goodwin artfully dodged this problem when he created Olipop, a gut-healthy carbonated drink. But a “probiotic beverage” wasn’t going to fly off shelves.
So he framed it differently: it’s a soda. A better soda with ingredients that can help your digestive system.
He wrapped a genuinely new idea in a form people already understood and craved. This “Trojan horse” approach meant customers never asked “what is this?” They just went straight to “I want it.”
Make sure you can explain your product in one sentence that doesn't require any prior knowledge. If you can’t, you’re not ready to launch.
6. You’re trying to make it perfect before you launch
Waze cofounder Uri Levine has a phrase that should be on the wall of every product team: “The biggest enemy of good enough is perfect.”
The company that launches an imperfect product and listens to real users will outpace the company that fusses over every detail.
“If you’re embarrassed to launch it,” Uri told me, “that’s exactly the right timing.”
Sure, it feels scary. But when you’ve got something that’s viable, get it out there. Listen, and then improve on what you learn.

I’ve seen a lot of great instincts die on the vine because the ideas and execution around them got in the way. Great leaders know how to protect those instincts from the mistakes that kill it.
Get clear on what you’re building before you build it. Involve the people who need to believe in it. Listen to your customers early and often. Change the right things. Make it easy to understand. And launch before you feel ready.
Do those things, and your next great idea has a fighting chance.
