2.2 Definitions & Key Terms (Part 2)
Key Takeaways
- FAR Part 2 definitions control which procedures apply—misclassify the requirement and you select the wrong Part pathway
- Acquisition, contract, solicitation, offer, and Contracting Officer are foundational terms that appear across every lifecycle phase
- Commercial product and commercial service definitions open Part 12 procedures and often enable streamlined approaches
- Micro-purchase and simplified acquisition concepts are threshold-driven; thresholds adjust over time—learn the procedural logic, not stale dollar trivia
- Exam traps frequently pair a wrong definition with a plausible but incorrect procedure (e.g., treating a noncommercial buy as commercial solely for speed)
FAR Part 2 — Definitions of Words and Terms is not a glossary to skim once. On CON 3990V, definitions function as procedure switches. If you mislabel the thing being bought, the dollar band, or the role of the person acting, you will select the wrong pathway among Parts 8, 12, 13, 15, 16, 19, and others—even if you remember clause numbers from training.
This section builds the definition set used constantly in Guiding Principles, Pre-Award, Award, and Post-Award items.
Why Definitions Control Outcomes
Consider three common switches:
| If the requirement is defined as… | Then procedures often shift toward… |
|---|---|
| Commercial product/service | FAR Part 12 (with simplified or negotiated methods as allowed) |
| Within simplified acquisition threshold (and other conditions) | FAR Part 13 simplified acquisition procedures |
| Above SAT / more complex negotiation | FAR Part 15 contracting by negotiation (unless another authority applies) |
The exam loves stems where the narrative sounds commercial or feels simplified, but the facts fail a definitional element. Always match facts to the definition before choosing a process.
Core Definitions You Must Own
Acquisition
Acquisition means 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. Acquisition begins at the point when agency needs are established and includes the description of requirements to satisfy agency needs, solicitation and selection of sources, award of contracts, contract financing, contract performance, contract administration, and those technical and management functions directly related to the process of fulfilling agency needs by contract.
Exam use: "Acquisition" is broader than "award day." Planning, market research, solicitation, award, administration, and closeout all sit inside the acquisition lifecycle. Guiding Principles questions often test this end-to-end view.
Contracting Officer
A Contracting Officer is a person with the authority to enter into, administer, and/or terminate contracts and make related determinations and findings. The term includes certain authorized representatives of the Contracting Officer acting within the limits of their authority as delegated by the Contracting Officer.
Exam use: Authority is delegated and limited. The label "Contracting Officer" is not ceremonial—it is a legal status tied to appointment. Distinguishing CO authority from program, COR, or finance roles is a recurring trap.
Contract
A contract is a mutually binding legal relationship obligating the seller to furnish the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the Government to an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders or task letters issued under basic ordering agreements; letter contracts; orders such as purchase orders under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications.
Exam use: Not every Government document is a contract. Understand that certain orders and modifications can form or change contractual obligations when properly issued. Conversely, informal emails or verbal "go aheads" from non-authorized personnel do not create valid Government contracts.
Offer
An offer is a response to a solicitation that, if accepted, would bind the offeror to perform the resultant contract. Responses to invitations for bids (sealed bidding) are offers called "bids" or "sealed bids"; responses to requests for proposals (negotiation) are offers called "proposals"; responses to requests for quotations (simplified acquisition) are quotations, not offers—though practice language sometimes blurs this, Part 2 precision matters.
Exam use: Procedure labels track solicitation type. Confusing IFB/bid, RFP/proposal, and RFQ/quotation leads to wrong evaluation and award rules.
Solicitation
A solicitation is any request to submit offers or quotations to the Government. Solicitations under sealed bid procedures are called "invitations for bids." Solicitations under negotiated procedures are called "requests for proposals." Solicitations under simplified acquisition procedures may require submission of either a quotation or an offer.
Exam use: Publicizing (Part 5), competition (Part 6), commercial (Part 12), simplified (Part 13), and negotiation (Part 15) all revolve around how the solicitation is built and released.
Commercial Product and Commercial Service
Commercial product and commercial service definitions (as set forth in FAR Part 2) are the gateway to FAR Part 12. In plain CON 3990V language: if the item or service meets the commercial definition (including certain of-a-type and evolved commercial concepts as defined), the acquisition generally uses commercial policies and clauses under Part 12, which are designed to more closely resemble customary commercial practice.
Why the exam hammers this:
- Commercial pathways can enable streamlined terms, different clause sets, and often different documentation expectations
- Misclassifying a developmental, highly Government-unique requirement as "commercial" to save time is a classic integrity/procedure failure
- Correct commercial classification is a facts-to-definition analysis, not a preference for speed
You do not need to recite every sub-definition word-for-word on exam day, but you must know that definition drives Part 12 applicability, and that "we always buy it this way" is not a definition.
Micro-Purchase and Simplified Acquisition Threshold (Conceptual Rules)
Thresholds in the FAR adjust over time (inflation adjustments and statutory updates). For CON 3990V preparation, prioritize conceptual rules over memorizing every stale dollar figure from an old slide:
| Concept | Procedural idea (learn this) |
|---|---|
| Micro-purchase | Very low-dollar purchases may use streamlined methods (often purchase card within authorized limits and policy) with reduced competition formalities compared to larger buys |
| Simplified acquisition threshold (SAT) | At or below the SAT (and when other conditions are met), FAR Part 13 simplified acquisition procedures may be used |
| Above SAT / other triggers | More formal procedures (e.g., Part 15 negotiation, sealed bidding where applicable) and additional documentation often apply |
Exam-smart approach:
- Identify whether the estimated value sits in micro-purchase, simplified, or higher-tier territory as a concept
- Apply the matching procedure family
- Check for overrides: required sources (Part 8), small business programs (Part 19), commercial status (Part 12), statutory preferences, or competition exceptions (Part 6)
If a practice question uses a specific dollar amount, treat it as a scenario fact for that item—but do not build your entire study plan on a number that may have been adjusted. WarU/FAI emphasize understanding when simplified vs negotiated procedures apply, not trivia recall of every historical threshold.
Head of the Agency (and related senior terms)
Head of the agency means the Secretary, Attorney General, Administrator, Governor, Chairperson, or other chief official of an executive agency, unless otherwise indicated—including certain deputies or assistants designated to act. Related terms (such as agency head, senior procurement executive, and chief of the contracting office) appear in approval chains for justifications, deviations, determinations, and other actions.
Exam use: Many Part 6 justifications, Part 1 deviations, and other high-impact decisions require approval at a specified level. The correct answer often hinges on who must approve, not only what must be approved.
Other high-frequency Part 2 terms
| Term | Why it matters |
|---|---|
| Supplies | Property broadly (with definitional nuances)—affects how requirements are described and which clauses apply |
| Services | Includes many non-personal service arrangements; improper personal services arrangements are a compliance risk |
| Simplified acquisition procedures | The Part 13 toolkit used at/below SAT when authorized |
| May / shall / should / must | FAR drafting conventions control whether a rule is mandatory or discretionary—read carefully in real work; exam stems often signal mandatory vs optional paths |
| In writing | Many actions require written documentation for enforceability and file sufficiency |
How Definitions Create Exam Traps
Trap 1: Wrong procedure from wrong label
Stem implies a commercial buy because "industry sells something similar," but facts show a unique Government development effort. Wrong path: Part 12 commercial shortcuts. Right path: analyze commercial definition carefully; if not met, use the appropriate noncommercial procedure set.
Trap 2: Treating quotations like sealed bids
RFQ under simplified procedures may seek quotations. Applying sealed-bidding award mechanics (or Part 15 formal discussions rules) without authority is a process error.
Trap 3: Role confusion
A COR or PM is described making commitments. Candidates who forget the Contracting Officer definition may "validate" an unauthorized commitment instead of identifying the authority problem and ratification path.
Trap 4: Threshold amnesia vs threshold obsession
Some candidates freeze because they cannot remember an exact dollar. Others memorize one old number and ignore the stem's stated value. Best practice: use the stem's value, apply the category logic (micro / simplified / formal), then check exceptions.
Trap 5: Ignoring required sources and socioeconomic overlays
Even with a correct dollar band, Part 8 required sources and Part 19 small business rules can change the path. Definitions get you into the right neighborhood; other Parts may still redirect the street.
Minimal DFARS Definition Awareness
CON 3990V expects primarily FAR fluency with minimal DFARS overlay. Practically:
- Know that DFARS may add DoD-unique definitions or refine terms for defense acquisitions
- Do not assume a DFARS definition erases the FAR baseline unless the scenario clearly points to a DoD-unique construct
- When in doubt on the exam, apply the FAR Part 2 concept first, then consider whether a DoD supplement would add constraints (approvals, clauses, source restrictions)
You are not building a DFARS encyclopedia for this exam. You are preventing FAR definition mistakes that cascade into wrong Part selection.
Study Drill: Definition → Pathway
Use this closed-book drill after reading:
- Read a scenario and underline facts that map to definitions (what is being bought, who is acting, how responses are requested, estimated value category, commercial vs not)
- Write one sentence: "Because X is defined as Y, the primary procedure family is Z."
- Name one override check (required source, competition exception, set-aside, deviation)
- Only then look at answer choices
That sequence mirrors how strong performers avoid attractive wrong answers.
Bottom line
Part 2 is the dictionary that decides which chapters of the playbook you open. Master the switches—acquisition lifecycle breadth, CO authority, contract formation, solicitation/offer types, commercial status, and threshold concepts—and the rest of CON 3990V becomes a navigation problem instead of a guessing game.
