There are two factors that will determine how quickly you can implement the various Herschel modules.
Firstly, the time your staff have free to learn how to use the system. The key to successful implementation is to let your staff explore Herschel and try things, before actually going live. The system can be set up with a training area for this purpose, if required.
Secondly, how much manufacturing data you already have available. You are not going to be able to use the more advanced facilities of the system if the information needed isn’t to hand. For example, the system can’t produce kits of parts for works orders if you haven’t entered any assemblies.
Typically a company will be using the basics of each module a couple of weeks after installation, but implementing all the features of the system can take several months.
