On Cost Reimbursable contracts, what are some key areas to focus upon:

- Audit every invoice - Make sure all the costs are applicable and chargeable to your project - Make sure the seller's work is progressing efficiently - Watch for the seller adding resources to your project that do not add value or perform real work. - Watch for resources being shifted from what was said in the original proposal (e.g. more experienced people proposed and less experienced people used) - Watch for seller charges that were not part of the original plan - Reestimate the cost of the project

On fixed price contracts, what are some key areas to focus upon:

- Watch for the seller cutting scope - Watch for the seller cutting quality - When the contract requires the seller's costs to be transparent, make sure they are real costs that have been incurred, not just future costs (unless there is an agreement stating otherwise) - Watch for overpriced change orders - Check for scope misunderstandings

Your company requires that before you purchase any routers or switches for the data center you are building, you need to solicit quotes from three separate suppliers prior to submitting the purchase request to the finance department.

A routine audit of a cost reimbursable (CR) contract determines that overcharges are being made. If the contract does not specify corrective action, the buyer should: A. Continue to make project payments B. Halt payments until the problem is corrected C. Void the contract and start legal action to recover overpayments D. Change the contract to require more frequent audits

A. Continue to make project payments. Halting all payments would be a breach of contract on the buyer's part. Voiding the contract and beginning legal action is too severe and connot be done unilaterally. Changing the contract to require more frequent audits does not solve the problem presented. A choice that said, "Halt payments on the disputed amount" would probably be the best answer. But, this choice isn't there, so best answer is to continue to make project payments.

C - It looks as if the vendor is asking for a cost-plus-fixed-fee contract. However, by asking for a fixed $12,500, the vendor is actually asking for a fixed-price contract. The cost and fee are just the components the vendor has estimated to come up with a final price. [PMBOK 5th edition, Pages 362, 363] [Project Procurement Management]

Typical Contracts

Firm Fixed Price (FFP) Fixed Price Incentive Fee (FPIF) Fixed Price Economic Price Adjust (FP-EPA) Cost Plus Fixed Fee (CPFF) Cost Plus Incentive Fee (CPIF) Cost Plus Award Fee (CPAF) Time &Materials (T&M)

What are the contract modifiers?

Fixed Fee- Incentive Fee Award Fee Economic Adjusted Fee

What are the types of contracts?

Fixed Price - Scope must be well known. Requires more work from buyer to set up and write procurement SOW. But, less work for buyer to manage. Big advantage is cost risk reduction for buyer. But, changes in scope must be carefully observed, otherwise the cost of the project may be elevated significantly because it is seen that the contractors get the contract by bidding the lower price and then try to cover the cost with any opportunity, such as added scope. Cost Reimbursable - Higher cost risk for buyer. Used when scope is less understood, and you need expert resources. MUST AUDIT seller invoices. More management from buyer required than fixed. This contract is also known as a Cost Disbursable Contract. In this type of contract, the seller is reimbursed for completed work plus a fee representing his profit. Sometimes this fee will be paid if the seller meets or exceeds the selected project objectives; for example, completing the task before time or completing the task with less cost, etc. Time and Materials (T&M)- done when you need resources quick but for SHORT DURATION. Needs lot's of day to day mgmt by buyer. A Time and Materials type of contract is generally used when a precise SOW can not be quickly created. In this type of contract, the project manager or the organization will provide the qualification or experience to the contractor to provide the staff.

What type of contract involves a fixed total price for a well-defined product or service.

Fixed-price/lump-sum

Benefits of having a contract change control system and what is in this system?

Having a contract change control system will allow you to establish the processes and procedures should you need to modify a contract. It contains paperwork, tracking systems, dispute resolution procedures, and approval levels necessary for authorizing changes. [PMBOK 5th edition, Page 383] [Project Procurement Also contains an extensive procurement changes approval process?

Cost Plus Award Fee (CPAF)

Here, the seller is paid for all his legitimate costs plus some award fee. This award fee will be based on achieving satisfaction on the certain performance objectives described in the contract. The evaluation of performance is a subjective matter, and you cannot appeal it. There is a difference between the incentive fee and the award fee. An incentive fee is calculated based on a formula defined in the contract, and is an objective evaluation. An award fee is dependent on the satisfaction of the client and is evaluated subjectively. Award fee is not subjected to an appeal. Example: If the seller completes the task meeting or exceeding all quality standards, based on his performance he may be given an award of up to $10,000 USD.

Fixed Price Economic Price Adjust (FP-EPA)

If the contract is multi-year long, a Fixed Price with Economic Price Adjustment Contract is used. Here you include a special provision in a clause which protects the seller from inflation. Example: About 3% of the cost of the project will be increased after a certain time duration based on the Consumer Price Index.

Cost Plus Incentive Fee (CPIF)

In a Cost Plus Incentive Fee Contract, the seller will be reimbursed for all costs plus an incentive fee based upon achieving certain performance objectives mentioned in the contract. This incentive will be calculated by using an agreed predetermined formula. Here the risk also lies with the buyer; however, this risk is lower than the Cost Plus Fixed Fee where the buyer has to pay a fixed fee along with the cost incurred. In a Cost Plus Incentive Fee Contract, the incentive is a motivating factor for the seller. If the seller is able to complete the work with less cost or able to complete it before time, he may get some incentive. Most of the time incentive is a percentage of the savings, which is shared by the buyer and the seller. Example: If the project is completed with lesser cost, 25% of remaining fund will be given to the seller.

Fixed Price Incentive Fee (FPIF)

In this type of contract, although the price is fixed, the seller is given an additional incentive based on his performance. This incentive lowers the risk borne by the seller. The incentive can be tied to any project metrics such as cost, time, or technical performance. Example: 10,000 USD will be paid to contractor as an incentive if he completes the work before two months.

Cost Plus Fixed Fee (CPFF)

In this type of contract, the seller is paid for all his cost incurred plus a fixed fee (which will not change), regardless of his performance. Here, the buyer bears the risk. This type of contract is used in projects where risk is high, and no one is interested in bidding. Therefore, this type of contract is selected to keep the seller safe from risks. Example: Total cost plus $25,000 USD as a fee.

Sharing Ratio?

Incentives are usually expressed as a ratio such as 90/10 sharing of savings. The buyer portion is always the first number. So, in this example, buyer gets 90% of the savings while the seller gets 10%.

IFB

Invitation for bid- generally this term is equivalent to RFP, but in some application areas may have a narrower or more specific meaning. But, Usually request for just a total price to do all the work. Is usually a sealed bidding processes used by Govt. contracting Contract type- FP Procurement SOW- Design

Which technique is mandatory in Procurement Management?

Make or Buy decisioning - determining which products or services will be bought, leased, rented or made in-house. This drives which outputs need to flow through rest of Procurement Management (Conduct Procurement, Control Procurement and close procurement).

Does buyer have the right to ask for anything not in contract?

What is the cost at which contractor assumes total responsibility for each additional dollar of contract cost?

Point of Total Assumption (PTA)

What is in Procurement Management Plan

Processes to be followed by Procurement Management process, Make or buy decision, sourcing strategy, types of contracts to be used, metrics used to measure sellers, procurement document formats, risks, constraints,assumptions

Type procurement where seller organization is preferred seller?

Single Source

Type procurement where seller organization is only seller?

Sole Source (e.g. Has patent)

Point of total assumption (PTA)?

The amount above which the seller bears all the loss of cost overrun. PTA = ((Ceiling Price - Target Price) / Buyer's Share Ratio) + Target Cost

When is fixed price contract right or wrong?

The main advantage of Fixed Price Contract is that both parties know the scope of the work, and the total cost of the task before the work is started. This type of contract is very useful if the scope of work is defined accurately. If done right, risk is with seller. Fixed price contracts are good for controlling the cost. However, changes in scope must be carefully observed, otherwise the cost of the project may be elevated significantly because it is seen that the contractors get the contract by bidding the lower price and then try to cover the cost with any opportunity, such as added scope.

Some procurement related items that would be tracked in the records management system:

The proposal, procurement statement of work, contract terms and conditions, etc.

Time & Materials (T&M)

This is a hybrid contract of Fixed Price and Cost Reimbursable Contracts. A Time and Materials type of contract is generally used when a precise SOW can not be created quickly. In this type of contract, the project manager or the organization will provide the qualification or experience to the contractor to provide the staff. This type of contract is used to hire some experts or any outside support. Here the buyer can specify the hourly rate for the labor with a "not-to-exceed" limit. Example: Technician will be paid $20 USD per hour.

Firm Fixed Price (FFP)

This is the simplest type of procurement contract. In this type of contract, the fee is fixed. The seller has to complete the job within an agreed amount of money and time. Any cost increase due to bad performance of the seller will be the responsibility of the seller, who is legally bound to complete the job within the agreed amount. Since the risk is borne by the seller, the cost tends to be higher. Another drawback of a Firm Fixed Price Contract is that, if the scope is not clear, there can be disputes between the buyer and the seller. Moreover, any deviation from the original scope can cost you a lot. Example: The seller has to complete the job for $100,000 USD within 18 months.

A leading telecom network operator has signed a procurement contract with an international telecom equipment vendor company to extend their network infrastructure nationally by 50%.
