In essence, ecosystems were competing on trust. Trust had become a source of competitive advantage. The question, then, is "How did they do it?" How did they design for trust? When we examined the successful ecosystems, we found seven trust tools embedded in them. Let me start with the first one, access. Many of the successful ecosystems define very well who is allowed in and who can be kicked out of the platform for bad behavior. HopSkipDrive does access well. It takes the drivers through a strict background check before they are hired into the platform. They also have a zero tolerance policy, which is superclear to everyone, so drivers know they can be terminated if they are caught illegally using their mobile phones while driving. Next is contracts. Trustworthy ecosystems formalize a relationship with all participants through contracts. If you've ever clicked the box "I agree to the terms and conditions," you signed an ecosystem contract. Then, there is incentives, and this is a big one. Successful ecosystems encourage cooperation through rewards, or by motivating participants to interact with each other in a positive manner. eBay and Amazon use reputation as an incentive. If you're a seller, and you have good reputation, you can charge higher prices for your products. Then, there is control, and I know it's a bit off to talk about control in trust, but we are not talking about forceful control -- it’s more like a gentle guidance, like an invisible hand nudging you in the right direction. Successful ecosystems shape the behavior of participants so the kind of cooperation required will emerge in the platform. Uber does control well, and it dictates to the driver the best route to take, so the passenger trusts the driver will not take the longer route just to make some more money. Then, there is transparency, which is superclear, isn't it? Sort of, ecosystems who are trustworthy make past and present behavior visible to everyone participating in the platform. And that's the reason why you feel a pit in your stomach if you've ever booked an Airbnb with a host who is new to the platform and doesn't have any reviews yet. And of course, Airbnb has managed to make transparency work both ways. If you are a guest, and you trash a house, the other hosts will know about it thanks to the Airbnb review system. Then, there is intermediation. How does the platform act as a middleman in the moments of truth of cooperation? Taobao, Alibaba's online shopping platform, does intermediation when it acts as an escrow agent between sellers and buyers. It basically holds the seller's money, until the buyer says she is satisfied with the product. Last but not least, mitigation. How does the platform handle mishaps or prevent them from happening in the first place? Did you know that LiveAuctioneers, an auctions platform for art, collectibles and antiques, has a broad protection program that guarantees payments on the platform? That's an example of mitigation. So those are the seven trust tools, the toolbox. Even more interesting is how they appear to combine in the successful ecosystems we studied. On the one hand, there is no silver bullet, no single tool that can solve for trust. On the other hand, you don't need the seven tools to be successful. You need 3.6, on average. So how do you pick? It depends on the kind of ecosystem you design. If interactions among the participants are key, like in most social-media ecosystems, you will require a combination of access, transparency and control in order to be successful. These are the very tools Facebook uses, and these are the tools, interestingly enough, causing Facebook so much grief right now. When there is a main last mile for the delivery of the promise, like in most gig economy ecosystems, then, you will require mitigation in order to cater for failed delivery. When there is a large asymmetry of information, say between sellers and buyers in used goods marketplaces, then, you'll require a combination of intermediation and mitigation. And of course, when there are many dimensions to the platform, you will require a larger combination of tools. Let me say one more thing, because I've been a consultant long enough to know that many of the business leaders watching this may be saying, "Hey, this is great. Let's digitize all these tools and we'll have the best and most successful ecosystem ever." Well, before you move to action, let me tell you something. Yes, digital plays a meaningful role in enabling trust, and in some cases, the very existence of the ecosystem. You could say that digital could be the backbone of systemic trust. However, there is no such thing as trustless trust.
