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.

It consolidates all logs into one place and provides required features and functionalities
Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to do RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The ability to turn off a flag is crucial when a task is not complete, especially if there is an error in a commit."
"LaunchDarkly has positively impacted my organization as the value we deliver to customers is much faster, and we saved a lot by using this feature instead of implementing it ourselves."
"The best feature LaunchDarkly offers is the capability of having a feature flag that we don't have to build in-house."
"These features in my current project have helped my team because they allow us to specifically target users to start turning on functionality, we can monitor the behavior and make sure that it's behaving as expected when the feature toggle is turned on, and then we can increase the usage."
"LaunchDarkly has positively impacted our organization by allowing us to confidently ship products across different environments, knowing we can easily turn off any feature that faces issues."
"From the development side, it allows us to manage multiple things."
"The setup is easy."
"It has really helped during the series of product lines and faster deployment and faster development."
"LogDNA consolidates all logs into one place, which is super valuable."
"We haven't had anything yet that we couldn't do through LogDNA."
"With LogDNA, which brings all the logs together in an interleaved stream, it allows us to take a transaction and relate it to other contextual events making the gathering of evidence for auditors and our internal RCA much more productive."
"The solution aggregates all event streams, so that if there are any issues, it's all in the same interface."
 

Cons

"We need experience to use it, and the initial setup can be difficult. Also, sometimes it has breakdowns."
"The feature where one feature flag is dependent on another could be explored more for our usage."
"Fetching information about multiple flags in a single action would be beneficial."
"I did not particularly like the rule area; there are many things to add into the rule to enable it, and I think we could make it easier or more customizable at the organizational level."
"I don't see any return on investment; I work in the platform team that has to manage the LaunchDarkly infrastructure, and I can't really see any return on investment."
"I think LaunchDarkly's customer support can be improved as it is not responsive."
"Right now, no improvements are needed."
"LaunchDarkly can be improved by managing old flags. We have an issue with old flags; it became very messy very fast and we need to be very disciplined about managing these flags."
"Every once in a while, our IBM cloud operational implementation gets behind. Sometimes, when we have a customer event, we do not get access to the latest logs for about 30 minutes, particularly for the sites that are heavily utilized. This is clearly not good. It is impossible to RCA when you can't look at the logs that pertain to the time period in which the event occurred. It could be more of an operational problem than a feature problem. I don't have visibility about whether it is a LogDNA issue or just an operational issue."
"No ability to encapsulate a query or a filter, and communicate or share that among the team."
"Scalability could be improved; we are using it through the IBM cloud deployment and on some of the data centers that are very heavily used, there is a significant lag in the event stream, sometimes 10, 15 minutes behind, which makes the RCA impossible."
