According to the scenario, customers' demand changes regularly but the construction project commencement often delays. If the contractor and the customer mutually sign a legally binding contract too soon long before the commencement, the contractor may suffer poor cash flow (it must buy the materials first but has to wait for long time to be paid). A framework agreement may help both parties.
A framework agreement is a formal agreement between two organisations that is intended to become legally binding in the event that a contract is created.
A framework agreement could benefit the both parties in the following ways:
- At the time of signing, the framework agreement has not yet become a legally binding contract. The contractor and client only agree on the principles of future contracts (such as whether the work can be subcontracted or how payment will be proceeded). A well structured framework agreement will allow both parties to apply changes before contract commencement, especially regarding price and quality.
- The framework agreement assures a certainty between the contractor and client.
- The administrative works is reduced under a framework agreement.

Lead time is the amount of time that passes from the start of a process until its conclusion. In procurement, lead time can be understood as the amount of time that passes from placing an order until the delivery.
In the scenario, the contract requires the supplier to make a delivery within 3 days since the order. This contract can only be amended with written consent from both parties. Therefore, there is no ground for shortening the lead time to 1 day because the new lead time is only the request of buyer. Then the supplier still makes delivery within agreed lead time.

The best way to manage conflicts of interest is through transparency and fairness. Including multiple suppliers in the market engagement process ensures no single supplier, including the one with a perceived connection, gains an advantage. This protects the integrity of the procurement process.

Express terms are the terms of the agreement which are expressly agreed between the parties. Ideally, they will be written down in a contract between the parties but where the contract is agreed verbally, they will be the terms discussed and agreed between the parties.
Implied terms are terms implied into the contract by the courts. They are not expressly set out in the contract but are taken to be as effective as if they were and as if they had been included from dayone of the contract.
The express terms and any implied terms together create the legally binding obligations on the parties.
Express terms are explicit and will normally override implied terms unless the implied term is created by statute and the law states that it cannot be overridden.

Advantages of using invitation to tender may be as below:
No Nepotism: Tenders or bids are evaluated on the basis of certain predetermined criteria, such as price, quality and value for money. In other words, the firm offering the highest quality product or service at the lowest price point would win the contract. As most tender documents are opened and evaluated in a public process, I think that there remains little room for nepotism or favoritism of any kind.
Value for Money: From the perspective of the client, tenders offer the greatest value for the amount of money spent. This is due to the fact that the client can choose from a wide pool of potential suppliers to select the ones that can produce the highest quality product or service at the lowest price point. This allows the company, establishment or organization to save money without having to compromise on quality. Therefore, despite being quite time consuming, tendering is, in my opinion, a profitable long-term process from an organization's point of view.
Encourages Competition: The process of tendering helps promote a competitive market. This is because a number of potential contractors, firms or suppliers get a chance to bid for every project. And because selection depends on quality and price, every bidder tries to reduce operational inefficiencies and redundancies as much as possible in order to lower expenses and improve quality. This entire process encourages healthy competition in the market and prevents complacency and laziness, which in turn provides a boost to innovation and new ideas.
Easier Entry: The system of tendering makes it easier and simpler for new firms to enter the market or even a particular industry. This is due to the fact that contracts under this system are awarded on the basis of predetermined, objective criteria. As a result, even a firm that is a new entrant to the market, having no connections or contacts in the industry, can win a prestigious and lucrative contract by providing the highest value for the client's money. This process therefore helps new firms to quickly get a foothold in the market or industry, thus significantly lowering the traditional barriers to entry.
