It is easy to look at a product range and decide that “one more product” is missing. The harder part is determining whether the missing product represents a useful new function or simply another variation of something already available.
Without separating these two issues, filling gaps in a product range can quickly turn into simply adding more SKUs.
A Real Gap Comes From a Need Existing Products Cannot Address
Suppose an existing kitchen faucet range mainly provides standard hot and cold water.
When considering a Three Way Kitchen Faucet, the important question is not whether three water paths are better than two. The question is whether the product addresses a use case that the existing range cannot cover.
For example, Rubinetti da cucina a 3 vie can bring different water supplies together at a single kitchen water point. This is fundamentally different from changing the handle shape or finish of an existing faucet.
The first may expand the functional coverage of the range. The second is usually another product variation within an already covered need.
This is the starting point for identifying a functional gap.
Look at the Existing Range, Not Just the New Product
A new function may sound attractive, but that does not necessarily mean the range needs it.
Start with the existing portfolio. Which kitchen water requirements are already covered? Which needs currently require another product or an additional fixture? Do any existing SKUs already provide a similar solution?
If the function offered by a three way tap kitchen faucet is already effectively covered by another product, adding it may simply provide a different way to achieve the same result.
If it addresses a clearly missing application within the current range, however, it represents a genuine portfolio extension.
For models that include a separate drinking-water path, product selection should also take into account the target market’s requirements for water-contact materials and overall product compliance. These are basic conditions for placing the product in a particular market rather than benefits created by the three-way function itself.
Functional Gaps and Style Gaps Should Be Evaluated Separately
A product range may genuinely be missing a certain color, shape or design style, but that is not the same as a functional gap.
Both can justify adding a product, but they should be evaluated separately.
A functional gap asks:
What user requirement can our current range not address?
A style gap asks:
Which product expression is missing even though the underlying function is already covered?
When these questions are mixed together, a range can appear extensive because it contains many visual variations while still leaving important functional needs unaddressed.
Instead of beginning with “Which product don’t we have yet?”, a better starting point is to ask which clearly defined usage requirements remain unresolved by the existing range.
Only when that answer is clear is a new product truly filling a portfolio gap rather than simply increasing the SKU count.
