SAIGE’s 10-stage iterative methodology supports a phased delivery approach which stresses the completion of manageable portions of the total solution in rapid succession. Throughout each iteration, SAIGE works closely with the client to review deliverables and obtain acceptance before progressing to the next stage. The 10 stages are illustrated in the graphic below.

In the Assess stage, SAIGE interviews the key client personnel to assess and document the "as is" state and to define and validate the "to be" state. The result is an end state route map.

During the Planning stage, SAIGE collaborates with the client to define critical success factors, document project scope, develop and complete a detailed project plan, and gather high-level requirements. In the Discover stage, these high-level requirements are expanded into detailed business requirements and functional specifications.

In the Design stage, SAIGE develops an integrated model describing how the business requirements will be implemented. Data requirements and logical models are also finalized.

During the Build stage, SAIGE develops and tests the system and solution components. The UAT (User Acceptance Testing) plan is also finalized. In Test, UAT is completed. SAIGE reviews the results of the test cases with the client before moving onto the Deploy stage.

Once testing is completed and approved, the solution “goes live” in the Deploy stage. During Deploy, training is conducted and a user helpdesk is functional with policies, procedures, and personnel.

For the Production stage, SAIGE offers two alternatives based on the client’s preferred method of sustaining the solution. If the client requires sustainment duties be handled by in-house staff, SAIGE will transition all duties to client personnel. If the client prefers to have sustainment duties outsourced, SAIGE will provide the appropriate resources for a predetermined period of time. Whichever alternative is selected, SAIGE tracks system performance in order to deliver metrics for final acceptance. Finally, in the Review and Accept stage, SAIGE compares the solution’s performance to business case metrics to ensure project objectives have been met.
