As new technologies emerge and others mature, technical sections are expected to come and go. The topical focus of a technical section can become less relevant, obsolete or it can evolve over time and begin to overlap with another technical section or other member group. Technical Sections must adapt, redirect, or in some cases, disestablish. This is a normal and expected part of the technical section life cycle. Following are the guidelines related to maintaining healthy technical sections and ensuring they continue to address the changing needs of SPE members.
