Slide 4

What Is an Open System Approach? The open frameworks methodology is a coordinated business and specialized procedure to: pick economically upheld determinations and measures for chose framework interfaces (outer, inner, useful, and physical), items, practices, and instruments, and fabricate frameworks taking into account secluded equipment and programming outline.

Slide 5

Business and Technical Approach It is a business way to deal with influence utilization of business items that guides assets to a more escalated preparatory outline push to result in a lifecycle cost lessening. As a business approach it underpins the DOD arrangement activities of CAIV, expanded rivalry, and utilization of business items. It is a specialized methodology that accentuates frameworks building, interface control, measured outline, and configuration for update. As a specialized methodology it bolsters the building objectives of outline adaptability, hazard decrease, setup control, long haul supportability, and improved utility. The Open Systems Approach Makes Sense Whether You are a Manager, Engineer, Logistician, Comptroller, or Contracting Officer.

Slide 16

REQUIREMENTS ANALYSIS OUTPUTS THREE VIEWS Operational Focuses on how the framework will be worked by clients, including interoperability needs. Sets up HOW WELL and UNDER WHAT CONDITION the framework must perform. Utilitarian Focuses on WHAT framework must do to create obliged operational conduct. Shows obliged inputs, yields, states and change rules. Physical Focuses on HOW the framework is built. Key to building up the physical interfaces and innovation necessities.
