Standardized our Java estate and have reduced licensing costs while maintaining strong support
Azul Zulu's ability to allow us to standardize our Java estate on a single and well-supported platform stands out as one of its best features. This standardization simplifies our compliance audits and ensures all our applications receive timely security updates.Azul Zulu positively impacts our organization by providing a platform that allows us to standardize Java on a well-supported platform. Without the high cost associated with other proprietary vendors, Azul Zulu provides an excellent platform for running our applications.

Improved agent adherence and scheduling have boosted satisfaction but reporting still needs real time
In terms of improvements for Calabrio ONE, since I do not work with forecasting, I think we could collaborate AWS with Calabrio ONE to get live data fed into Calabrio ONE, which would be even greater for forecasting. We pull the majority of our reports through Calabrio ONE, and something I have noticed is that for the intraday report, if we want to pull data at 12:30, we have to wait until 12:45. It is a 15-minute refresher window, which is lagging behind. This delay is the same for any report being pulled. I do not have a grand overview of forecasting, but it generally takes a long time, and my agents have not been able to collaborate AWS with Calabrio ONE in the forecasting aspect. Apart from that, everything else is working great on Calabrio ONE. I would love it if it was more real-time and if I could download the data almost immediately without waiting for that 15-minute buffer. I rate Calabrio ONE a seven because I feel it could be improved. As I mentioned, the 15-minute buffer is an issue, and the real-time feeding into forecasting could be better. If we could control Shift Bags within Calabrio ONE instead of using another application like Teleopti to manage Shift Bags or control overall shifts, that would be even better. Right now, we use a combination of Teleopti and Calabrio ONE to decide the Shift Bags. The quantity and quality of results provided by Calabrio ONE are accurate 95 percent of the time. The forecasting feature in the application might not be the most accurate, which is an area where we do have issues, especially when scheduling breaks at intervals where calls might be at a higher volume. Those are rigged. Apart from that, since breaks and other meetings get allotted automatically, we do have to manually move them around because that forecasting is not accurate. If that could be improved, it would be great.

Quotes from Members

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

Pros

"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."
"We've had no issues with stability."
"I have found the video capture to be the most valuable feature."
"I have used many tools such as Verint, IEX, and Avaya, but I saw that Calabrio ONE was far better than other tools."
"Calabrio ONE has increased agent satisfaction to a great extent."
"I was able to use Calabrio to provide data and analytics in a visually stimulating fashion which captured my audience's understanding with ease."
"Easier for RT and TM's to view current adherence."
"Makes agent schedules more accessible and easy to use."
"The dynamic scheduling functionality allows the agents to be more empowered which was not an option on our previous tool."
"Overall I feel this is a great product with a fantastic support network with an exciting features roadmap ahead."
 

Cons

"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."
"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."
"Being able to "publish" or rerun the schedule for only one agent would be ideal."
"Need a column for hours scheduled on main page."
"A few of the features were "nice to have" features, but version 9.3 had some "deficiencies"."
"It would be nice if this product supported operating systems other than Windows. Some work is needed on better support of multiple browsers."
"Try and correct bugs prior to release."
"I rate Calabrio ONE a seven because I feel it could be improved."
"It sometimes needs quite clunky work arounds for certain things, e.g. If I add exceptions into agent schedules such as holidays or long term sickness, it's not easy to just delete them."
"Calabrio ONE's user interface is a bit slow, but this issue likely stems from our internet package rather than the application."
