The whole science of management is changing to accommodate this new type of employee. Communication is the greatest challenge faced by management. Some corporations have dozens of divisions world-wide, and employ hundreds of thousands of people. Effective operation of the corporation requires that people working on different parts of a project share information about it. Sometimes a problem on one project can be solved by a person who has similar experience on another project.
Professional people are also expensive.
This all seems very intimidating to the individual who has just accepted a first job in a huge corporation. Your first work assignments will be relatively straightforward tasks you were hired to do. If you get stuck, you will find lots of other people in your group, including your supervisor, who will help you accomplish your tasks. After 2 to 5 years, your performance on projects will lead to your establishing your niche in the organization, and in 4 to 10 years you may be an expert in your field. In all of your work, you will become more valuable as you know and are known by more people with other special skills or knowledge.
