Overall Satisfaction with Optimizely Digital Experience Platform (formerly Episerver DXP)

Primarily used for controlled introduction of a feature. Perform A/B testing and fairly quickly determine the effectiveness of a proposed change in user experience.
  • Provides quicker release cycle for the way the product cards should be displayed.
  • Provides feedback for new product introduction and how it'll be perceived.
  • Allows rapid blackout from user experience changes that alters traffic flow.
  • Can use better interface for managing test, including scheduling and notification.
  • Feels too heavy for simple projects, though this isn't a factor once past the PoC stage.
  • Notification on various aspects can be made more powerful and granular if such a need arise.
  • Speed to market.
  • Richness of user interaction data and possible AI/ML analyses.
  • Relatively quick learning curve for new team members.
  • Almost immediate payoff in terms of the benefit.
  • Easy to justify the TTM benefits to upper management.
  • Still somewhat hard to justify ROI, though this is not my expertise.
There is a big difference between the two: Google Optimize uses Bayesian analysis while Optimizely uses Frequenting. There is a risk of counting multiple visits. Google Optimize data isn't available instantly (if I remember correctly). Optimizely's analyses dashboard is a lot richer and offers a better experience, though it may get intimidating.

It is well suited for heavy-duty A/B testing where management would like to see and quantitatively determine the effect of a change. It is not so efficient to try for a single page simple form, except when the form is part of a larger workflow. The security model is not very well understood, including RBAC and protection against injection attacks.
