I was able to install, configure a demo and present it in very short-order. The code is easy to understand, separates logic from presentation (see discussions on MVC elsewhere) and does a great job doing what it says it will do.
While it may seem hard to please both the HR department and the IT department, the JobGrok extensions do just that.
I would recommend downloading, reading, installing and configuring the extension to give it a try. The reviews can only do so much, but when there didn't appear to be any "negative" reviews when I was looking for this type of application, I figured it would be worth investigating. I was not wrong. The reviews about it being easy are true.
You do need to do some reading, and I would recommend going to their forums. Most of the questions I had were answered there.
I might like to see more community involvement on the forums though. From what I was able to see, almost all of the questions were answered by the developers. Kudos to them, but perhaps as more people start to realize the potential of this extension the community will be able to step up and assist in the development of a potentially great package.
Beyond just the OS Model, JobGrok has easy to understand code, well commented and easy to follow along. No obfuscation or complex objects with hidden trails to find. Modifications are relatively easy if you read the notations. Just what good OS code should be.
On the implementation side, it is easy to install, and easy for end-user admins to manage once it is up and running. This is key since most "managers" of this type of package will be from Human Resource departments, while installers and code maintenance will be done by IT staff.
While ready for prime-time, the developers seem to also understand that, like most Open Source projects, it is growing and evolving. My experience with the support staff has been positive when suggesting areas of improvement and possible additions to the package. I do not have enough time using JobGrok yet to give any feedback on how/when those suggestions get implemented, but they have been very receptive to ideas.
Our company is moving ahead with using JobGrok, and I have to at least recommend giving it a serious try. I was able to give a working demo to our HR department with just a few hours of installation and population of the multitude of options available. This extension definitely deserves two thumbs up. I look forward to seeing this project grow even further.
