If the feature you're working on is to add PayPal as a payment method, and the reason is to increase conversion, then be sure to always show the current conversion rate and the result you're hoping to achieve. Most important, after the feature goes live, be sure to highlight the impact on that conversion rate. If the impact was good, celebrate it. If the impact was not what was hoped, then emphasize to everyone that, while you did ship the feature, the result was not successful. Point out specifically what was learned, but explain that you have other ideas for ways to get the desired result.
