I have heard of various manufacturing strategies for example "just in case" and "just in time" but Proven seem to be operating on a "not in time" parts strategy. This is a very dangerous position for them to be in.
The longer term plan on parts seems to be to make all their suppliers and installers deliberately and consistently over order on parts so that they hold stock for warranty and replacement parts instead of Proven. I cant imagine a lot of the smaller installers will want to see all their money tied up in holding excess Proven parts. I guess i must have misunderstood something!
Your comments about keeping existing customers happy are very pertinent.
I am yet to hear about what will happen with the warranty.
Will keep you posted.
