Approach to interface analysis

• Identify Integrations– Functional teams create CSDs.– System of Systems Architecture (SoSA) describes the enterprise level

integration points needed for the overall Nodal solution.– Integration Design Authority (Technical & Business Architects), project

teams and integration vendors work together to produce artifacts as described previously

• Repeatable Interface Specifications & Design– Integration artifacts are produced that contain:

• Data Element Name, Element Attributes, Volumetrics, Data Frequency etc.• Business Triggering Events that drive the movement of information

– The integration teams use these artifacts to analyze the interface and develop Use Cases

• Identify gaps, integration characteristics, mismatches and transformations of data that is necessary between systems

– Integration specifications and Use Cases are the input to design and implementation of the integration between systems.

– Feed the design back into SoSA.

Integration Timeline

• What to expect– Several integration specification & integration design documents

are currently in preparation. External interfaces will come to TPTF for approval.

– Many are being produced significantly ahead of Projects’ build schedules

– Rework may be necessary to Projects, SoSA and integration artifacts as the interface specification work progresses

• Timeline Dependencies– Work in progress - the detailed build schedules have not been

finalized between projects and EDS’s– Shows earliest start, latest finish & delivery dates for interface

specification and design artifacts– Based on approximately 150 external interfaces and 250 internal – Does not account for substantial refactoring
