Organization is going to receive a bunch of technical documents from contractor - drawings, procedures, etc. - for the whole plant.
Currently contractor keeps its project documentation in Lotus Domino.
- What software you recommend for Document Control?
- What is the best way for migration from Lotus?
- My organization uses SAP for maintenance, finance; it would be logical to extend SAP to document control as well, but I do not know if there are SAP modules for Document Control?
Mike T suggested MOSS, which is a good product.
However, I suspect that the needs are quite basic, so Windows Sharepoint Services (WSS) alone might just do the trick. WSS is the backbone of MOSS, but is missing quite a few of the features (including workflow). But for basic document management (security and version control), the document libraries in WSS will do just fine.
And the price is right! It is included (for no additional charge) with Windows Server 2007.
To provide some sort of answer to your other questions ...
2 - Domino migration - Don't let the contractor make it your problem. Ask them to provide the docs in a standard format (i.e. RDF or PDF). Worst case, you will need someone to manually put them into WSS. This isn't nearly as much effort as you think, and clerical help if far less expensive than consulting help.
3 - SAP does indeed have a document management system (SAP DMS), and I imagine it works well, particularly for documents connected to SAP transactions. I have no idea of the license and implementation costs, but I would be shocked if they are less than 100 times the implementation costs of WSS.
Try testing out Microsoft Office SharePoint Services (MOSS 2007 or the upcoming 2010). It may not be a perfect fit for every occasion. It's main strength is document management and collaboration. Due to it's broad appeal and good underlying structure built upon .NET, it can help solve many other problems if you are willing to put the time into it.
The easiest way to integrate Domino is to use Lotus Quickr 1. We also have a big Lotus Domino Server farm but we're using sharepoint because of it's office integration and it is really easy to use.
Whatever you're going to use I recommendend you to hire an consultant to get started with such a project. Both solutions are really big and you can waste much time without reaching your goals.
Document control in SAP in managed by these services (which one depends on what you want to do):
