Items that employees use on a daily basis and need readily available are kept in the workspace. Everything else is put in another location where files and materials can be managed more efficiently. Also, due to the increasing amount of team-based work that organizations are implementing, the need for team files is increasing. These files can be kept in a central or shared location rather than duplicating files for every team member. A lot of clients look to alternative officing for space efficiency.
Accessibility is only one factor to consider in choosing the type of storage equipment.
The importance of the other factors varies with the needs of the organization. You have to look at the physical requirements, the needs of the users, and the constraints of the building. When we work with a client to reduce their workspaces or design space for mobile workers, we design workstation storage to include immediate access materials. Everything else can go to a central storage area. For this we've tried conventional storage solutions and two-drawer cabinets, but they take up a lot of space.
