The goal is to improve the client’s competitive edge by injecting an appetite for change into the organization and then applying that focus towards its external environment, utilizing the Alignment Strong model through the formulation, formation, and linkage of 10 integral processes, practices and systems identified in the Vitruvian alignment schematic.
  • Strategic Planning: GSG encourages the development of an adaptive business model and one year strategic plan driven by a defined management team and supporting accountability processes.
