Acquisition Management System Fig. 3: p. 4 of 79
Motivation All FAA investment initiatives must go through a Service Analysis (SA) and CRD process. During SA and CRD, the service organization must build a legitimate and compelling case that shows how a proposed initiative fulfills an FAA service need In both SA and CRD, a set of products will be developed by the service organization that act as both milestones for progressing through the AMS lifecycle and as building blocks for creating a sound acquisition case. from p. 2 of 79
Service Analysis Phase Fig. 4: p. 5 of 79
Requirements: Service Analysis • Inclusion in EA Roadmap • The roadmap effort is currently in progress. • Concept of Operations (CONOPS) • CONOPS is both a stand-alone document and a sub-section within the Shortfall Analysis Report. • Shortfall Analysis Report (App. C) • This report re-states the problem being addressed by the initiative, identifies the severity of the problem, and explains the methods used to generate the shortfall estimate. • Preliminary ACAT Determination Request (App. A) • Acquisition Category (ACAT) classifies project based on dollar thresholds and appropriate qualitative factors. • The assigned ACAT Level determines the future governance of the program. • Approved CRD Plan (App. B) • The CRD plan outlines the approach the service organization will employ to complete the CRD phase of AMS.
Service Analysis: Concept of Operations • The CONOPS document includes the following sections (App. K): • Executive Summary • Description of Operational Need • Service or System Justification (Description of Desired Change) • Proposed Service or System • Operational Scenarios • Impacts • References • Appendices
Service Analysis: Shortfall Analysis Report • This report re-states the problem being addressed by the initiative, identifies the severity of the problem, and explains the methods used to generate the shortfall estimate. • It contains, but is not limited to, the following products.
Service Analysis: CRD Plan The CRD Plan is the document that outlines the approach the service organization will employ to complete the CRD phase. Its purposes are: • Ensure agreement among all organizations providing CRD resources • Define products to be completed during the CRD phase • Establish a milestone schedule for the CRD effort
CRD Plan: Other Deliverable Activities • Conduct Safety Risk Management • Develop Preliminary Requirements (pPR) • Develop Range of Alternatives • Estimate Costs and Benefits • Create Investment Analysis Plan (IAP) • Finalize ACAT Designation Request • Prepare for Investment Analysis Readiness Decision (IARD)
CRD Phase: Concept of Use (CONUSE) • The CONUSE document is an expansion of the CONOPS: • Focus is on the user (i.e. user’s language, needs, expectations, etc.) • It describes specifically how users will employ the proposed capabilities and how they will function in the operating environment (secondary focus) • The CONUSE will be used as a foundation for performing the functional analysis and, in turn, developing the preliminary Program Requirements.
CRD Phase: Concept of Use • The CONUSE document includes the following sections (App. L): • Background Information (including References) • Description of Operational Need • Service or System Justification • Proposed Service or System • Operational Scenarios • Description of Impacts • Appendices
CRD Phase: Functional Analysis • The Functional Analysis product takes stakeholder needs and translates them into the functions required to satisfy the need. • Higher-level functions are decomposed into sequentially lower-level sub-functions. • A function is defined as a characteristic action or activity that needs to be performed to achieve the desired service. • Stakeholder needs are derived from the Needed Services product, the Preliminary Shortfall product, the CONOPS, and the NAS System Requirements document (SR-1000). • During Functional Analysis, focus is on what the new service will do, not how the service will be performed.
CRD Phase: Functional Analysis • Through the process of decomposing and analyzing functions, a description of the system emerges and becomes the framework for developing requirements and physical architectures. • Analysis of the operating environment is also required. • Changes to an environment or multiple operating environments may require defining additional functions. • Required analysis tools: • N2 Diagram • Functional Flow Block Diagram
Functional Analysis: Generic N2 Diagram • N is the number of entities • Functional or physical entities are placed on the diagonal axis • The remaining squares of N x N matrix represent the interface inputs and outputs Fig 4.7-5 : System Engineering Manual
Functional Analysis: Example N2 Diagram • Blank square indicates no interface between respective functions • An ‘X’ placed in square corresponding to Row I, Column J indicates data flow from function I to function J. Fig 4.7-6 : System Engineering Manual
