a. This NASA Policy Directive (NPD) provides the overall policy framework for NASA's strategic acquisition process with appropriate references to other key processes and directives. This strategic acquisition process complies with NASA obligations as a Federal agency and is applicable to each of NASA's major areas of investment (Flight Programs and Projects, Information Technology and Institutional Infrastructure, and Research and Technology) to ensure the efficient, effective use of the resources entrusted to the Agency.
b. NASA's strategic acquisition process supports obtaining, or advancing the development of, the systems, research, services, construction, and supplies to fulfill the Agency's mission and other activities which advance the Agency's statutory objectives. Within the framework of this strategic acquisition process, NASA utilizes multiple authorities to meet these objectives. NASA's authorities include, but are not limited to, grants, cooperative agreements, international agreements, and Space Act Agreements (SAAs), in addition to NASA's acquisition authority to contract for goods and services through procurements. The Agency also has the authority to enter into other types of arrangements depending on the circumstances, such as Inter-Agency Agreements (IAAs), leases, concession agreements, property loan agreements, and Cooperative Research and Development Agreements (CRADAs). This NPD establishes the strategic acquisition governance framework under which these authorities will be used.
c. This strategic acquisition process supports NASA's strategic management system, as defined in NPD 1000.0, Governance and Strategic Management Handbook, by augmenting the Agency governance structure for decision making with the processes necessary to support efficient, effective execution of Agency programs and projects. This strategic acquisition process begins with an idea or proposal that aligns with NPD 1001.0, NASA Strategic Plan, and fulfills an identified need or objective and ends with the completion of a program or project or the final disposition of a product or service (see Figure 1.0). The integration of the strategic acquisition process and the strategic management system ensures special attention is given to major acquisitions and significant adjustments to portfolio content. Major acquisitions that are directed at and critical to fulfilling the Agency's mission, entail the allocation of relatively large resources, or warrant special management attention.

d. This integration of the strategic acquisition process and the strategic management system is implemented by the Strategy Implementation Planning (SIP) process that guides specific budget and acquisition decisions. This allows the evaluation of issues such as the appropriate application of administration priorities, Agency strategic planning and new initiatives in a portfolio of programs and projects, and budget availability to assess both short-term and long-term alignment. The SIP process is implemented through select reviews conducted at the direction of the NASA Administrator, resulting in guidance to inform the strategic acquisition process. This guidance is incorporated into the Strategic Programming Guidance of the Planning, Programming, Budget, and Execution (PPBE) process and further applied to decisions made in the Agency Acquisition Strategy Meetings (ASM), conducted by the NASA Associate Administrator. See attachment D. -- Figure 1.0-NASA Strategic Acquisition Process.
e. It is NASA policy to:
(1) Have a strategic acquisition process that complies with:
(a) All applicable laws and regulations.
(b) Applicable Agency and Center directives, requirements, procedures, and processes.
(c) The Agency's core values.
(2) Execute the strategic acquisition process through a disciplined strategic management system employing:
(a) Clearly defined roles, responsibilities, processes, and requirements for planning and execution.
(b) Both a short-term and long-term perspective.
(c) Monitoring and/or metrics that ensure effective implementation.
(d) Appropriate authorizations and approvals that ensure decisions are made in a timely manner. Decisions, approvals, and authorizations are documented in signed agreements. A signed agreement between authorized employees of NASA organizations serves as a binding agreement between those organizations. A change requires renewed approvals and authorizations or creation of a new agreement.
(e) A process that integrates applicable lessons learned and knowledge sharing.
(f) Appropriate consideration of all NASA authorities when developing the acquisition strategy.
(3) Have checks and balances built into the strategic acquisition process that ensure:
(a) NASA capabilities, as required by senior Agency management to efficiently and effectively implement the NASA Strategic Plan, are maintained, including workforce and infrastructure, over both the short term and long term.
(b) Existing NASA capabilities are used rather than acquiring new capabilities when existing capabilities are available and are considered necessary for NASA's strategic future.
(c) All major new acquisitions and significant adjustments to portfolio content are reviewed by senior Agency management to ensure they fulfill an identified need that is aligned with the NASA Strategic Plan and are compatible with expected resources and capabilities.
(d) The acquisition strategy is reviewed and agreed upon by senior Agency management before authorizing resource expenditures for major acquisitions.
(e) Application of Technical Authority, Dissenting Opinion, independent review, safety, quality assurance, and tailoring principles, as defined in NASA policies and procedural requirements, are applied and tailored for the selected authority.
(4) Ensure that personnel involved in the strategic acquisition process have the appropriate skills, competencies, and certifications across the range of management, technical, and business disciplines necessary to carry out their individual acquisition responsibilities.
(5) Ensure that organizations having a substantive interest in the acquisition strategy are effectively integrated into the strategic acquisition process as early as appropriate and throughout the duration of their interest in order to include their needs, benefit from their experience, and encourage communication.
(6) Ensure acquisitions that require cost, schedule, and/or confidence level estimates are based on realistic estimates and achievable schedules that:
(a) Cover all costs associated with meeting the need or achieving the objective, including:
(1) Costs such as institutional support requirements, technology investments, and multi-Center operations.
(2) Costs associated with Agency constraints.
(b) For major acquisitions, are based on probabilistic cost and scheduleestimate(s) and confidence level(s) that have been approved by the decision authority.
(7) Ensure when acquisition decisions are made the strategy, direction, and execution phases have consistent acquisition commitments to assure overall alignment for all authorities using Agency resources with cost estimates by fiscal year and applicable Federal budget account projections.
(8) Ensure organizations meet programmatic, institutional, technical, cost, and schedule commitments to fulfill the NASA acquisition strategy, as determined by the selected NASA authority.
(9) Incorporate a risk-informed decision-making process that includes the identification, analysis, and management of programmatic, institutional, technical, cost, schedule, environmental, safety, management, industry, and external policy risks that might jeopardize the successful execution of the Agency's acquisition strategies.
(10) Consider, when developing an acquisition strategy, the full spectrum of acquisition approaches, as appropriate, to advance the Agency's objectives, taking into consideration providing best value, maximizing competition, and preserving the Agency's core capabilities. Seek to optimize the use of NASA's, industry's, and academia's expertise, and maintain the required supporting workforce and industrial base.
(11) Ensure that execution of the acquisition strategy respects and appropriately maintains the relationship between NASA and its suppliers or partners, including their separate roles and responsibilities.
(12) Promote competition and small business participation throughout the strategic acquisition process.
(13) Require disclosure of financial interests from those persons participating in the strategic acquisition process, and avoid personal conflicts of interest to the greatest extent possible in all acquisitions.(14) Ensure that organizational conflicts of interest are identified and resolved throughout the strategic acquisition process.

NPD 1000.5, NASA Acquisition Policy, dated January 15, 2009.
Acquisition - Obtaining, or advancing the development of, the systems, research, services, construction, and supplies to fulfill the Agency's mission and other activities which advance the Agency's statutory objectives. (The definition of acquisition in this document is used in a broader context than the FAR definition to encompass the spectrum of various NASA acquisition authorities and approaches to achieve the Agency's mission and activities).
REFER TO NID 1000.110 FOR REVISED DEFINITION
Acquisition Strategy - The plan or approach for using NASA's acquisition authorities to achieve the mission of a program or project. It includes the recommendations from make/buy analyses, the recommendations from competed/directed analyses, proposed partnerships and contributions, proposed infrastructure use and needs, budget, and any other applicable considerations.
Acquisition Strategy Meeting (ASM) - A decision-making forum where senior Agency management reviews and approves program and project acquisition strategies. The ASM focuses on considerations such as impacting the Agency workforce, maintaining core capabilities, make-or- buy decisions, supporting Center assignments, potential partnerships, and risk.
Approval - Permission by an authorized employee to proceed with a proposed course of action. Approvals must be documented.
Competition - An acquisition strategy whereby more than one entity is sought to bid or propose in order to provide capabilities. The awardee is selected on the basis of criteria established by the activity for which the work is to be performed.
Cooperative Research and Development Agreements (CRADA) - CRADA means any agreement between one or more Federal laboratories and one or more non-Federal parties under which the Government, through its laboratories, provides personnel, services, facilities, equipment, intellectual property, or other resources with or without reimbursement (but not funds to non-Federal parties) and the non-Federal parties provide funds, personnel, services, facilities, equipment, intellectual property, or other resources toward the conduct of specified research or development efforts which are consistent with the missions of the laboratory; a CRADA does not include a procurement contract or cooperative agreement.
Major Acquisition - Acquisitions that are directed at and critical to fulfilling the Agency's mission, entail the allocation of relatively large resources, or warrant special management attention.
Procurement - The acquiring by contract with appropriated funds of supplies or services (including construction) by and for the use of the Federal Government through purchase or lease, whether the supplies or services are already in existence or must be created, developed, demonstrated, and evaluated.
Space Act Agreements (SAA) - The National Aeronautics and Space Act of 1958 (herein, the Space Act), as amended (51 U.S.C. 20113(e)), authorizes NASA "to enter into and perform such ... other transactions as may be necessary in the conduct of its work and on such terms as it may deem appropriate, with any agency or instrumentality of the United States, or with any state, territory, or possession, or with any political subdivision thereof, or with any person, firm, association, corporation, or educational institution."
Strategic Management/Strategic Management System - A series of integrated activities that enable the Agency to establish and execute strategy, make decisions, allocate resources, formulate and implement programs and projects, and measure performance. The comprehensive set of processes that NASA follows is collectively called the strategic management system, which is described in NPD 1000.0.
Strategy Implementation Planning Process (SIP)- The SIP process represents an integrated Agency-level activity to transform high-level Agency strategy into guidance for implementing NASA's portfolio and budget planning.
Supplier - An individual, partnership, company, corporation, association, or other service having a contract or agreement for the design, development, manufacture, maintenance, modification, or supply of items under the terms of a contract or agreement. A government activity performing any or all of the above is considered a supplier.
