PDQ Inventory is great if you have a local network of computers on or off a domain. As long as you have a way to log into them with common credentials. Great for large organizations, particularly ones interconnected with VPNs. PDQ Inventory isn't so great for PCs that aren't connected to the same LAN the server is on. (i.e. non-vpn remote users) They used to have a remote agent you could install, but it was removed after numerous issues.
Symantec Ghost Solution Suite is well suited to standard images of company approved software and standard configurations for all users. When every user has the same computer configuration, it is easily managed with a standard image across the board. It is less effective if you need to have multiple configurations for different groups. It becomes cumbersome to manage all the various images. When you add to the complexity by having to address the different drivers for the different hardware model computers, this only adds to the overall number of images you will have to manage, create and keep updated. I find Ghost most helpful with standard hardware model computers and one or two images company wide.
Logical - If I want to do something with the software, it is quite clear on how I need to go about that. There isn't some weird process that is proprietary to just that vendor and is counterintuitive. What I want to see is displayed with just a couple clicks.
The built-in help menus and general ease of use render whatever systems support there might be almost irrelevant. There is stability in the system's simplicity; if you're in the position to use such a product, you're your own best friend. Simple web searches more often than not turn up the solution to any little niggles, such as what silent install switches specific applications require (a remarkably wide choice of options exist). System updates are timely and unobtrusive, installing in no time at all. Maybe I've just been lucky; if so, long may it continue!
This software was referred to us by an IT professional. Previously, we were installing the software with the help of remote desktop applications but it was very time consuming; it was wasting the user's time since he could not use his computer. After testing PDQ Deploy, we just never looked back.
A positive impact of Ghost would be time. To deploy computers form scratch is very time consuming and labor intensive for the IT Department. Ghost clearly saves the time of the IT departments staff to quickly get a new computer out to user so they can spend their time on addressing other issues and being more productive.
Time is money. If the IT department is spending hours preparing computers and employees are out of a computer for an extended period of time waiting for one to be loaded, this is money lost to the company in paying employees to sit around and wait for a computer to be configured.
