UPDATE | WITH COMPLETE SOLUTION.
How would you define depth and breadth of an offeror's experience to be
included in a solicitation/evaluation? - ANS.... -Breadth of experience
reflects the Offeror's experience in performing the full range/all of the
efforts required. Depth of experience reflects the magnitude, significance,
and applicability/relevance of the Offeror's experience in performing each
of the efforts required. An offeror's past performance should only be
included if it is similar in nature to the new solicitation that is being
evaluated. It could be the qualifications/certification that the offeror has or
previous/relevant work that the offeror had completed.
A legally binding contract must contain what elements? - ANS.... -An offer
and an acceptance. 1. Component Parties (capacity, competence, and
Authority) 2. Mutual Assent (binding offer, valid acceptance, and meeting of
the minds) 3. Consideration (the bargained for legal value of the deal) 4.
Certainty of terms (the contract must be unambiguous) 5. Lawful purpose
(Violations of the law will not be enforced)
You receive a customer's procurement package. In it, the PWS addresses
key personnel required. The customer wants to evaluate the availability and
commitment of the proposed key personnel when evaluating offers. What
would you recommend the customer include in the instructions to offerors
for proposal submission requirements and evaluation factors? - ANS.... -I
would recommend that the customer include a requirement for commitment
letters from all vendors and state in the solicitation that key personnel with
also be evaluated by both their qualifications and by evaluating their
commitment letter. Section L - Instructions, Conditions and Notices to
Bidders, Section M - Evaluation Factors for Award.
,Why is inspection and acceptance important to the Government? - ANS.... -
FAR 46.5 Risk of loss of or damage to supplies shall remain with the
contractor until, and shall pass to the Government upon Delivery or
Acceptance. After 30 days without rejection, it is considered accepted by
the GOV. The KO wants to ensure the COR inspects all received supplies
and services to ensure we get what we ordered and are good stewards of
the taxpayers money. To prevent fraud, waste and abuse. It is part of the
quality assurance.
Explain the difference between an offeror's experience and an offeror's
past performance - ANS.... -Experience details work that the contractor has
done in scale and scope. Past performance is a report of how well they did.
Performance can be obtained by CPARS, Past Performance Retrieval
System (PPIRS), and surveys.
Explain the "Bona Fide Needs" rule. - ANS.... -It is a rule of appropriations
law. It mandates that a fiscal year's appropriations only be obligated to
meet a legitimate—or bona fide—need arising in (or sometimes before) the
fiscal year for which the appropriation was made. Penalty is Job, 2 years in
Jail and $5K fine or both.
What is the order of precedence for a solicitation or contract in accordance
with FAR 52.215-8? For example, the specifications require a different item
than is stated in the Schedule (Section B). What does the contractor use? -
ANS.... -Order of precedence Rule: UCF: a tiebreaker based on where the
argument is in the contract and not in the contract itself.
(a) The Schedule (excluding the specifications).
(b) Representations and other instructions.
(c) Contract clauses.
(d) Other documents, exhibits, and attachments.
(e) The specifications.
,Once all receivables have been delivered/completed and verified by the
customer/COR, the ACO or KO reviews the contract files for remaining
closeout actions. Why is contract closeout so important? What actions
need to be taken in closeout? Closeouts is required per FAR 4.804, it is
necessary to ensure all actions under contract are complete, final payment
is processed, and left-over funds are deobligated. - ANS.... -1. Required
deliveries completed and accepted by the GOV.
2. All services performed and accepted by GOV.
3. All option provisions if any expired.
4. GOV gives the contractor notice. Past performance evaluation (if
required). Completion settlement and final voucher submitted. Second,
release of claims signed. DD 1594 Contract Completion Statement and
1597.
On a full and open competitive negotiated acquisition, you have received
five proposals and determined that discussions are needed, what is the
process of determining which offerors are in the competitive range for these
discussions? - ANS.... -If the Contracting Officer decides that an offeror's
proposal should no longer be included in the competitive range, the
proposal will be eliminated from further consideration for award. The
Contracting Officer must provide written notice of this decision to
unsuccessful offerors in accordance with FAR Part 15.503(a). The notice to
each offeror must state (1) the basis for excluding/eliminating its offer, (2)
the basis for the determination, and (3) that a revision of its proposal will
not be considered.
The Contracting Officer must prepare a written competitive range
determination based on all evaluation factors, including a complete
rationale for decisions to include or exclude specific proposals from the
competitive range. This document is the Competitive Range Determination
memorandum.
, If you have a competitive requirement, how will you determine the Best
Value Approach to use in regards to choosing LPTA or Tradeoff? Also, give
at least one example when each is appropriate. - ANS.... -LPTA is when
price is the most important factor. Lowest price, no tradeoff. Tradeoff is
when other factors outweigh cost. It is the most flexible. We always
consider cost. Evaluation of factors in mandatory on contracts exceeding
$1MIL. (Price, quality or technical, Past Performance). Tradeoff would
usually be used in more complicated requirements where certain qualities
are more important to the customer than others. LPTA would be used for
simpler supply buys.
How would you mentor a new Contract Specialist (recent intern graduate)
that has been assigned to your team? What tools would you provide to your
specialist in accomplishing their duties? What tools do you use in
accomplishing your duties? - ANS.... -Conduct an Initial counseling that
covers duties and expectations. Set goals and priorities. Review and
approve their Individual Development Plan (IDP), Assign a coach and
mentor. I would mentor a new CS assigned to my team by helping them
through a common SAT purchase, explaining the steps and procedures
involved. I would show them local SOPs, Policy Letters, PCF, SAM,
FARsite, and WAWF.
What is an unauthorized commitment? What steps do you take in
evaluating, processing and approving an unauthorized commitment? -
ANS.... -An unauthorized commitment is $$ committed by an individual who
did not have the authority to obligate the $$. To approve a UC, you will
need to go through the ratification process.
Unauthorized commitments violate federal law, federal regulations, and the
Government-wide Standards of Conduct for Federal Employees, and the
DFARS. Ratification. Cases that cannot be ratified under FAR 1.602-3 may
be subject to resolution as authorized by FAR Subpart 33.2, Disputes and
Appeals.
