Analysing the analysts:
Should we trust them?
silicon.com. 20/02/2001
There are lies, damn lies and statistics. It's
a famous quotation and one sure to wrap up conference presentations with
a chuckle. But is the issue of analyst accuracy all too often
overlooked? Analyst quoting reporter Ben King investigates...
The market for mobile ring tones and related
products will be worth £3.7m by 2005, says Gartner Group. It sounds
credible enough and it's an interesting statistic - one that has even
appeared in a couple of magazines. Trouble is, it isn't true, at least
not according to Gartner, which doesn't even study the mobile
accessories market.
No-one is quite sure where this figure came from,
but such is the faith analysts inspire, it was a while before anyone
exposed it as a fake. Who knows, major business decisions may even have
been based on the forecast.
As technology develops, we rely on industry
analysts and their predictions more. Businessmen trying to sell
technology and related services use them. Politicians and civil servants
do too. Journalists are the worst culprits for mindlessly regurgitating
statistics.
The above figure happens to be made up, but how
accurate are the real ones? Often, they're not.
Take a classic analyst miscalculation -
videoconferencing. It's pretty easy (and possibly slightly unfair) to
find examples that just didn't happen. Here are a few:
- In February 1997, IDC published a report
forecasting about 600,000 desktop videoconferencing units to ship to
business customers, and some 5.4 million to sell into the home market
during 2001. Most analysts joined in the frenzy. A month later, Frost
and Sullivan predicted the market would be worth an anticipated $43bn by
2003.
- Will Strauss, president of US-based market
researchers Forward Concepts, pushed the boat out furthest. He told
Newsbytes in March 1997: "Within three years videoconferencing will be
standardised on all PC operating systems including Windows and Mac."
We couldn't get up to date figures. IDC hasn't
published anything on videoconferencing for a while. Let's just say
nothing like 5.4 million domestic terminals have ever been sold.
Various other technologies, like ISDN and ATM, have
also underperformed expectations. Every analyst has their favourite
prediction that went wrong - usually something strange, like integrated
voice-data terminals or mobile base stations for the home.
For various reasons, they tend to over-hype flops
more often than they dismiss things that turn out to be huge. A rare
exception is the exponential growth of SMS text messaging. It was
largely unforeseen two or three years ago, but a staggering 15 billion
messages were sent globally in December 2000, analysts say. (Actually it
was the GSM Association.)
There are more examples, but they're slightly
harder to track down. Analysts like to shift categories to make old
(wrong) predictions seem closer to the mark.
How do they come up with their projections? It's a
sensitive issue, and quite a lot of analyst houses are reluctant to talk
about it on the record, either in detail or at all.
When researchers come out with predictions for most
markets they rely on a variety of factors. They'll look at current
market size (if there is one). They'll look at how fast a market is
expected to grow. Take something like suntan lotion - they'll look at
when people use suntan lotion, how fast the holiday market will grow,
how many people are potential suntan oil users, how many people will
have disposable income to spend on suntan lotion, whether there are
competing products.
All this is fed into massive spreadsheets. Out the
end spurts a figure.
Mary-Ann O'Loughlin is chief analyst at Ovum, one
of the few analyst houses prepared to discuss the business with us and
how accurate predictions are. She didn't want to put a figure on
forecast accuracy. "It's our best estimate," she said. "No forecast is
infallible."
And apparently it's not really a numbers game,
anyway.
"Ninety per cent of the value is in the qualitative
part of our reports," she added. "It's more in the scenario than the
numbers that come out at the end."
IDC also fought shy of making specific claims for
its data accuracy. "As a services company we are driven by the
capabilities and characters of our analysts as much as a rigorous
methodology when commenting on the market," said IDC's Martin Hingley,
VP EMEA Systems Group, in a written statement.
All the analysts we spoke to emphasise they work
closely with the industries they comment on and have a position of trust
allowing them to get 'inside information' from the major companies in
sectors they cover.
So why do they sometimes get it spectacularly
wrong? Besides drawing on their own expertise, they are known to follow
what other analysts' publish and say. They sometimes even credit each
other as sources, typically for figures. This means mistakes tend to be
across the board, even though some analysts do go out on a limb
sometimes.
A possible hole in their information - which might
explain occasional misjudgements - is a lack of accurate information
about what customers will actually use. Most examples of great
analytical pratfalls concern consumer products which consumers just
didn't bother with.
In the B2B arena analysts tend to have a much more
accurate grasp of what's going on because they spend so much time
talking to businesses. Indeed, through their consulting work they help
to guide - to an extent - what businesses actually buy. They're the
ones, primarily, who dream up the three letter acronyms - ERP, CRM, even
TLA - which keep the IT industry busy. Directly or indirectly, they help
to tell the vendors what to produce and the buyers what to buy.
"When we get it wrong, it's because we don't
understand what people really want," Ovum's O'Loughlin admitted. "That's
the hardest thing to discover."
There are ways to avoid this - market research,
focus groups and so on - but they can be blunt tools. At best, they give
a rough indication, and can seem unscientific.
"There's a lot of common sense, and a little bit of
intuition [in our predictions]," added O'Loughlin. "My teenage daughters
are an invaluable resource."
It seems business intelligence comes from many
sources, and like anything, we develop trusted suppliers.
