Most organizations acknowledge the need for Electronic Document Management (EDM). However, many consider only their office-size documents when they implement their EDM. 
If you haven’t considered the importance of your large format documents as well as your small format documents in your Electronic Document Management Plan, then now’s the time to think about it. As public and private industry sectors require digitization of their records, whether for disaster prevention, green practices, or storage expense reduction, they need to maintain a consistent workflow processes across all sectors regardless of the document size.
These benefits of Electronic Document Management apply regardless of document size:
- Eliminates the drudgery of bulk paper filing and the difficulty of finding what’s been filed
- Filing flexibility – the same document can be filed under several different references for easy reference no matter how you search for it
- Integrating large format electronic files as well as small format documents enables you to achieve one consistent and logical filing structure for ALL your documents.
Paper and PC-generated files received from any source can be filed into one EDM, where they can be viewed or acted upon by any user or users simultaneously across a network or the Internet. This ability to share both small format and large format documents has several advantages:
- inter-departmental issues can be resolved more quickly
- Customer questions can be answered without having to search through paper documents
- Reduction in printing and copying documents saves time and money
- Important documents don’t get mislaid
- Freeing up expensive floor space used for paper storage can result in large cost savings
How to Include Large Format Documents in your EDM
To stay competitive, organizations must be able to capture content from hard copy documents with speed, accuracy, and flexibility. This can sometimes be a more complicated process for large format documents than it is for small format. Organizations can eliminate workflow processing bottlenecks in scanning large format drawings, charts, maps, or other
over-sized documents directly into EDM or ECM software and electronic capture software by choosing a large format scanning solution that offers an industry-standard interface, 
high quality scans and document-specific presets. For instance, Contex’s EDM/ECM solutions provide these abilities and eliminate the challenges of processing documents larger than B-size in a business process workflow. Include a turnkey indexing product to make the processing of large format documents into an EDM workflow as easy and seamless as possible. This will save both time and money in the long run.
You should establish how you want to retrieve your digital assets prior to beginning the large format scanning project. This is critical to the success of managing large format drawings in your EDM. Whether you choose to manage your drawings in a simple electronic file folder or decide to index by project names, drawing names or other criteria that help identify the drawing, make sure that you stick to the indexing scheme throughout the scanning project. This ensures that your large format assets can be easily located by entering one of the tags that relate to the file, enabling instance access to the information. The integration of large format assets within document management systems can help reduced cost and improve productivity, with a resulting positive impact on your bottom line.
