Configuration management features improve workflow but require a steep learning curve
I need to work more with Helix Core to identify specific areas for improvement. However, it has an extensive feature set that leads to a steep learning curve, where users need to learn quite a bit of features to work with it effectively.

"It can be adapted to any process flow and easily be integrated with other in-house tools using the ClearQuest API."
"Customization level of the tool to meet client’s requirements, you can do almost all of the customizations for a project or ticket management system, and notification, hooks, and UI customization are very stable."

Cons

"The user interface could benefit from a more modern look and feel."
"It’s very expensive, especially considering that there are much more economical options out there."
"Lack of a modern web interface compared to other systems might discourage customers."
"However, the user interface seems very static and the user experience was not the best."
"The part of Perforce that could be most improved is its automatic resolving of code merge conflicts."
"However, it has an extensive feature set that leads to a steep learning curve, where users need to learn quite a bit of features to work with it effectively."
"There are scalability issues when there is too much traffic, such as when there are extremely huge amount of calls by APIs."
"It scales well, but installation and server management gets technically very complicated when the installation grows."
"Perforce does not appear to have an enterprise scale software test environment. We sometimes serve as their software QA department."
"The offline versioning needs to be improved."
