Has increased developer confidence by enabling safe production releases using targeted feature toggles
I wish we were using more targeting in our feature toggles and I wish we were using more feature toggles as well as feature toggle dependencies. Making one feature toggle or one set of feature toggles dependent on another one would allow us to turn them all on or turn them all off at one time. For improvements in LaunchDarkly, managing team members and access to those team members was challenging. We could add team members through Terraform and do it programmatically, and then modify it through the user interface. However, once we started modifying things through the interface, we weren't able to go back to using any configuration programmatically for the team members. It made it challenging to orchestrate team member management. The other aspect I wasn't particularly fond of was when they started adding AI to the interface and deployment interface. It reminded me of old school wizards when installing software and simplified the interface too much, removing some of the engineering control I preferred.

Tracking model metrics and artifacts has improved workflows but documentation needs clarity
In my opinion, the best features Weights & Biases offers are that they are easy to adapt and navigate through inside their UI, and I can check the model artifacts by versions. Sometimes when it throws errors, I can check them easily, and it has access control that's a good fit for corporate usage. What I like about the UI and the access control features is that they are just easy to navigate, easy to understand, and finding is also easy. Weights & Biases has positively impacted my organization a lot because many users are using Weights & Biases for tracking models and seeing metrics. I believe it places a lot less weight on setting up this tracking method. I can share specific outcomes or metrics since using Weights & Biases. For example, I can check each epoch's model artifacts and see how effectively it worked on my evaluation set, and it can be fetched by the unique ID.
