What it means
The method grew out of wartime manufacturing shortages and is now standard practice in construction, engineering and product design. The central question is not what does this part cost, but what does this part do, and what is the cheapest reliable way to do it.
The financial appeal is that the savings are permanent and repeat on every unit produced. Taking a few dollars out of a product built hundreds of thousands of times a year moves gross margin far more reliably than a one off round of budget cuts ever will.
A typical exercise runs as a workshop with design, purchasing, production and finance in the same room, working through a function analysis before generating and scoring alternatives. Candidates are ranked on annual saving against the cost and risk of making the change, and only those that leave the function intact go forward.
Timing matters enormously. Most of a product's cost is locked in at the design stage, so value engineering applied before tooling is committed is far cheaper than a redesign after launch, when retooling and re-testing can swallow the whole saving.
The obvious failure mode is quietly reducing function and calling it value engineering, which resurfaces later as warranty claims, returns and lost customers. A genuine exercise measures the function the customer perceives just as carefully as it measures the cost.
In practice
Real-world examples.
Example
A construction firm bidding for a school building comes in $2,000,000 above the client's budget. A value engineering session swaps a glass curtain wall for a brick and window system that holds daylight and thermal performance at the same level while removing $2,300,000 of cost.
Example
An appliance maker finds its dishwasher uses three different screw types where one would do. Standardising the fastener cuts 40 seconds from assembly time per unit and shrinks the spare parts catalogue, saving on both labour and inventory.
Example
A medical device company must re-certify any change to a part that touches a patient. It confines its value engineering exercise to packaging and the outer casing, where the regulatory risk is low, and still finds a 9% reduction in total unit cost.
Think of it
“Value engineering is finding cheaper ways to deliver what customers need-cutting cost without cutting value.
Formula
Calculation
Value = function delivered / cost of delivering it
Annual saving = saving per unit x annual volume
A garden equipment maker builds a cordless trimmer at a unit cost of $180 and sells 240,000 units a year. A value engineering workshop replaces a machined aluminium bracket with a moulded part and consolidates eleven fasteners into four, with independent testing confirming no loss of strength or working life.
The change removes $27 from the unit cost, so the new cost is $180 - $27 = $153, a reduction of $27 / $180 = 15%. Because the function is unchanged, each dollar now buys $180 / $153 = 1.176 times as much function as before, an improvement of about 17.6%.
Across annual volume the saving is 240,000 x $27 = $6,480,000. The workshop, retooling and re-testing cost $400,000, so the first year net benefit is $6,480,000 - $400,000 = $6,080,000, and every year after that carries the full $6,480,000.Case study
Seen in the real world.
The following is an illustrative and entirely fictional case. Kestrel Mobility, an invented maker of folding wheelchairs, was losing tenders to imported rivals on price and its board pushed for a 20% cost reduction across the range. The first attempt was pure cost cutting: thinner tubing, a cheaper seat fabric and a lower grade bearing.
Returns rose sharply within a year, and the warranty provision consumed more than the savings had delivered. On the second attempt the fictional company ran a proper value engineering exercise, starting from what each part had to do rather than what it cost, and found that a redesigned folding hinge could replace nine parts with three while improving the fold action customers had complained about.
Kestrel's illustrative outcome was a 16% unit cost reduction with a lower warranty rate than before. The difference between the two attempts was not effort or ambition but whether function was protected as the starting point.
Watch out
Common mistakes.
- Treating value engineering as a polite name for cheapening the product, which trades a visible cost saving for invisible losses in returns, reputation and repeat sales.
- Running the exercise only in purchasing, so the conversation is limited to squeezing supplier prices instead of questioning the design that dictates those prices.
- Starting after the product is already tooled and certified, when the cost of changing it often exceeds the saving available.
Questions
People also ask.
Is value engineering only for manufacturers?
No, and it is used heavily in construction and increasingly in service design, where the functions being analysed are process steps rather than physical parts.
How is it different from target costing?
Target costing sets a cost the product must hit before design begins, while value engineering is the technique used to reach that number or to reduce cost on an existing design.
Who should be in the room?
Design, purchasing, production, quality and finance at minimum, because a saving that looks obvious to one function is often the very thing another function depends on.
