Understanding the value for money principle
Launch library · evergreen read

Value for money is the idea that a purchasing decision should weigh price against quality, risk and whole of life cost, rather than simply accepting the lowest bid on the page. A cheaper option that fails early, needs constant rework, or carries hidden risk can easily cost more overall than a pricier option chosen at the outset.
Applying the principle well requires evaluators to define, in advance, exactly what quality and risk mean for the particular purchase, since vague criteria leave far too much room for a decision to be justified after the fact rather than reached honestly through the process itself. Clear, published criteria protect both the buyer and every bidder involved.
Critics sometimes worry that value for money becomes an excuse to avoid awarding the contract to the cheapest bidder for less defensible reasons, which is exactly why documentation matters so much. A properly recorded value for money assessment shows precisely how each factor was weighed, rather than asking anyone to simply trust the final outcome.
