Standardizing on a single PDF vendor, which can provide a complete solution at an affordable price, to address the differing needs of dissimilar users, provides many benefits.
Enterprises have many different types of users. They have power users and novice users. Users that employ multiple devices and users that prefer only one. Those that use desktop computers and those that use mobile devices. Some users utilize cloud or virtualization services like SharePoint and Citrix and some don't. Some users need access to PDFs with rights-managed confidential information, some don't. These different user types form “pockets of utilization” across the enterprise.
What's more, users may use different computing platforms and software applications to create documents than those who receive them, which can mean trouble with opening and displaying documents.
