Project contracts

A contract is a written, verbal or implied offer with agreement to provide a good or service in return for some kind of benefit.
Benefit is known as ‘consi­der­ation’
Both parties must receive consid­eration for a contract to be binding
Client receives as consid­eration some type of product or service
Vendor’s consid­eration often represents some form of payment
Within Australian contract law, a contract is only valid where there is an offer and agreement and the contract incorp­orates consid­eration for both parties.
When consid­eration takes the form of a monetary payment the type of payment agreement maybe ‘fixed price’, ‘cost plus percen­tage’ or ‘cost plus fixed fee’.

Costs plus percentage contract

Payment amount to the vendor is an agreed upon percentage of the overall project costs.
Works in the vendors favour.
No incentive for the vendor to control costs
The higher the costs the more the vendor earns.
Vendor is incent­ivised to augment their costs to increase the projects profit margin.
The client would almost certainly end up overpa­ying.

Cost plus fixed fee

Payment to vendor is a fixed fee + actual costs of the project
The cost of the project and the amount payed to the vendor are separated, removing a common conflict of interest
This time the vendor has no incentive to offer only the most expensive software on the market
Vendor is more likely to recommend software which best suits the needs of the client
Rather than focusing on augmenting their profit margin the vendor may choose instead to focus on reputation and work to keep the client as happy as possible
Price of the software will have no effect on the behaviour of the vendor
Protects the vendor from costs incurred through accidental undere­sti­mation, and protects the client from unnece­ssarily augmented costs when a cost plus percentage type contract is negotiated
It seems this contract meets the needs of both parties’ best

Cost plus contracts

Two types of ‘cost plus’ contracts
Cost plus percentage
Cost plus fixed fee
Cost plus contracts are useful when long term quality of the project is a priority
An obvious disadv­antage of ‘cost plus’ contracts is reduced unders­tanding at the beginning of the project of what the final cost may be.

Fixed price contract

Contract in which final payment amount is agreed to and set in stone at the very start of the project.
Know what you are going to pay and do not need to worry about unpleasant surprises or haggling.
Accurate estimation of time required is extremely difficult in system design and/or implem­ent­ation projects
Risk of undere­sti­mating is high and common, which means the risk to the vendor is high
Conseq­uences of an inaccurate estimation could have the vendor’s team working at a loss to complete the project.
Common strategy to avoid inaccurate estimation is not ideal either: the vendor would pad their estimate to allow for every possib­ility and the client would almost certainly end up overpa­ying.
Vendor is incent­ivised to keep his costs as low as possible to increase the margin on the project, this encourages cutting corners to produce the product as quickly and cheaply as possible, which is exactly the opposite of what most clients would hope for.
Quality of the project output long term may be undermined by use of this contract type.
