The
product life cycle (PLC) is one of the best-known marketing
concepts in the world. First referenced in the 1920s
by economists reporting on the automobile industry,
the term applies biology to new brands, makes, and models
of package goods, cars, magazines, electronics, and
so on, tracing each as it passes from birth to growth,
growth to maturity, maturity to decline, and ultimately
to death. But while it's universally known, it's not
unanimously accepted. In fact, manyCopernicans
among themthink it's downright absurd to try to
draw kinship between living things, which have a finite,
genetically predetermined, uncontrollable course of
development, to products, services, and, especially,
brands, who's "life" is completely in the
hands of its management and competitors.
Unlike
living things, there are no statistics published on
the average life of brands, in general or by category.
Given that the vast majority of new products and services
barely make it to their third birthday, we'd estimate
the average is 13 years, about the same as lions and
tigers. But this number is really meaningless. Brands
do not necessarily have a finite end; well-managed,
they can live forever. The American Express, Budweiser,
Camel, Coca-Cola, Gillette, Western Union, and Wells-Fargo
brands, for instance, are all still going strong in
their respective categories after 100+ years. And even
if a brand dies, it can rise again from the dead, though
perhaps in more limited distribution. Take PanAm Airlines.
Another
problem is that one of the basic premises of PLC is
that products require different strategies at different
stages of the life cycle. All marketers need do, PLC
proponents explain, is plot where their brand is on
the PLC continuum and follow the prescribed strategies
to maximize profits at that stage. For example, during
the growth stage, action plans include improving the
quality of a product or adding more features; entering
new market segments; or increasing distribution. At
the decline stage, action plans include cutting prices
and reducing marketing budgets.
Sounds
nice and easy, but understand that researchers have
identified as many as 17 different PLC patternsthere's
the growth-slump-maturity pattern, the cycle-recycle
pattern, the classic S-curve, and more. How are you
supposed to know what pattern fits your brand? If you
don't know what PLC pattern applies, how do you know
that your brand is truly in decline? Maybe it's just
a slight decline before a dramatic increase in another
growth period, or maybe it's a leveling off of sales
with no more peaks and valleys, just perpetual maturity.
There's just no way for a marketer to know, nor is there
a scientific way to measure and pinpoint an exact location.
There's no way to know because the pattern is as much
a function of academic researchers attaching a label
on a random phenomenon as it is a serious taxonomic
classification of a real underlying pattern.
Also
bear in mind that the recommended actions at each stage
are based purely on observations and anecdotes of what
other companies have done. There's nothing proprietary;
it may or may not be relevant for a particular brand;
and it certainly isn't directly linked to increasing
profitability. As Nariman Dhalla and Sonia Yuseph wrote
in the Harvard Business Review nearly 30 years
ago, "the PLC is a dependent variable which is
determined by marketing actions; it is not an independent
variable to which companies should adapt their marketing
programs."
As
an alternative to PLC, customer equityin the simplest
terms, the lifetime value of all of a brand's customers
(for more on the topic click
here)is a much more predictive measure of
how much longer a brand is likely to live if the company
maintains the status quo. The more equity a brand has
relative to competitors, the longer it will live irrespective
of its chronological age. It's also a much more prescriptive
tool; if a brand has weak equity, a transformational
marketing program can improve it and prolong its life.
While
there's nothing you can do to make a dog live to age
75, there are many things you can do to double the life
expectancy of a brand.
