A/B Testing and Experimentation

Our team uses it as a core part of our release and Validation process across client projects, not just internally.

Feature Rollouts and Testing

we've integrated Optimizely Feature Experimentation into our development and release processes to address several key business challenges, including employing it for feature flags for controlled rollouts of new functionalities, and for A/B testing which has become integral to our decision-making process.

Risk Mitigation and Validation

That has solved a longstanding problem of all-or-nothing releases, where any new algorithm introduced carried a huge rollback risk.

Integrations with Other Tools

We currently can't correlate feature flagged experiments with Salesforce CRM data.

Ease of use and understanding

Tools aren’t easy to understand

Reporting and results overview

From an app's perspective, it's very difficult to be fair. Whilst with, I guess other features, more generically speaking, I think it'd be the results side of things. We'd really love to have that exported out into a way that we can have an overview of the experiments that we've run and the results and be able to understand our win rates and those sorts of things. I think it's very difficult to have a nice overview of the results and insights as well. Just having a single space for us to look at our insights is where we're struggling, I guess.

Please provide some detailed examples of things that Optimizely Feature Experimentation does particularly well.
