User management is actually rather late to the IT party. Back in the days when IT was referred to as Management Information Services (MIS) and "the computer" lived in a big, climate-controlled glass room, the only management of users was making sure they lined up properly waiting for the delivery of printouts. "Authorization" meant identifying yourself to the guard at the door and "access control" meant having a key to the door of the computer room. The only people who actually interfaced with the computer were called "operators" and they all used a single account -- actually no account at all.
Timeshare systems, the advent of UNIX-based shared hosts, and especially the proliferation of workgroup, departmental, and enterprise networks of personal computers lead first to the use of user accounts to separate "my stuff" from "your stuff" and later to the concept of shared things, or "our stuff." Rudimentary security, in the form of simple passwords to control access, was fairly prevalent by the 1980s; however, the use of file, folder, and application security didn't really hit its stride until the late 1980s and early 1990s.
UNIX systems allowed a matrix of permissions that was three by three -- read, write, and execute permissions for the user, his or her group, and "everybody", whereas Novell, and later Microsoft, introduced a rich array of rights and privileges that could be assigned to individual users or groups of users. The advent of directory services—both those tied to the network operating system (NOS) directories and those that evolved from email address books into global access lists (GALs) and into what are now called enterprise directories -- further enriched the opportunities to control, on a granular level, the authorization of users and their access to resources.
The Evolution of Provisioning
Provisioning is both a more recent development than user management and a much older concept. Today's use of the term provisioning (often called electronic provisioning to differentiate it from older, manual provisioning) is simply describing the automation of the many manual tasks that Human Resources, Facilities, and IT departments have had to do for employees for many, many years. The term was adopted from the telco environment in which it has been used for decades to cover the process of providing premises equipment (for example, a telephone), identification (that is, a phone number), and a dial-tone to subscribers.
However, the telcos didn't create the term; they simply appropriated it from its earlier usage, which goes back centuries. When Christopher Columbus importuned Queen Isabella to pawn her jewels to support his expedition, it wasn't that he needed the money to hire a crew -- typically the crew was paid at the end of a voyage with a share of the ship's profit. Mariners needed lots of money to "provision" their ships -- provide food, rope, guns and powder, blankets, livestock, trade goods, navigational instruments, and more. Everything the ships might need had to be bought before they sailed because there were no shops along the way. Store keepers, unlike sailors, required "cash on the barrelhead" (you didn't get the barrel until they got the cash) for all purchases. This entire process was and still is called "provisioning the expedition."
Today's usage is surprisingly close to that definition, as electronic provisioning seeks to provide an employee with everything needed to navigate to and use the resources of the enterprise. You might say we've moved from provisioning the world explorer to provisioning the Internet explorer.
