So welcome back to our course on stretegic innovation.
Today, we're starting on our second module.
We're going to look at different types of innovations, and how organizations
can effectively take advantage of the opportunities that these present.
If you remember, in the first module, we talked about some of the generic
challenges that young markets, and young technology present for
firms and the idea that firms need to develop a ambidexterity.
A capability to be able to effectively align themselves for
the needs of mature markets as well as young technologies and young markets.
And we talk a lot about how to do that but
what we didn't talk about is differences between kinds of innovations and
technologies, and there are such differences.
The idea of ambidexterity is going to continue to be a theme, but
scholars have developed several different typologies of innovations.
Perhaps, the most important of these is the distinction between disruptive
technologies and sustaining technologies that Clayton Christensen developed.
And that's where we'll be going next and that's where we'll be spend most of
our time but we'll take a look at others as well.
And then in the second half of this module,
we're going to think about how an organization can respond to innovations.
If we think of them as coming in a stream where there is different kinds
of innovations and technoloies, and market opportunities that
are working through the organization's different units and so on.
And how do we go ahead and manage those as a portfolio, so to speak.
So the first lesson will be about disruptive technologies.
We'll introduce that term and talk about what Christensen meant by it.
The second lesson we'll talk about responding to dsruptive technologies.
And also we'll get into other typologies of innovations,
competence destroying versus competence sustaining.
The third lesson we'll talk about this idea of innovation streams and
the last one will be about corporate entrepreneurship.
So in this video, we're going to talk about disruptive technologies.
I'm sure you've heard and maybe used the term disruption.
It comes out very frequently, you hear that firms are disrupting a market or
that they have a disruptive strategy.
What does this mean?
Well, the idea of disruption is not something that you might have
heard 25 years ago, and in fact, it was popularized by Clayton Christensen,
who was a professor at Harvard Business School at this point.
Now his research showed that what he called disruptive technologies
were very hard for established market leaders to respond to.
And that's something that we've seen already but
we haven't actually talked about the idea of a disruptive technology.
He had a very particular meaning for that term.
And in fact, it's almost like disruptive technologies have become too popular.
He and others have suggested that it's the term disruption has come to be used for
many more things than disruptive technologies as such,
and you know that's fine, right?
If we take disruption just to mean something that means your competitor
can't succeed by doing what they've done before that's perfectly fine.
And in fact, there is a book by Professor Gans who goes ahead and
uses that very definition for disruption.
But I do think is worth us looking at what Christensen had to say, because he
had a very interesting way of bringing together the dynamics of organizations,
and markets, and technologies that builds on what we've talked about already.
And so what we're going to do in this video is to talk through to Christensen's
idea of disruptive technology and
make sure that we have a good sense of what that is.
And then as the module proceeds, we'll expand on this groundwork.
So what exactly is a disruptive technology?
See, Christensen really focuses on categories,
ways where we can say this is in this category, this is in this category.
There's two types and it's really important to get the category right.
What he said is that there were a number of categories,
radical versus incremental innovations.
Competence destroying versus competence sustaining or preserving innovations.
He said look, those actually are not the right categorizations.
The right categorization is between what he called a sustaining technology and
a disruptive technology.
And the way that you distinguish between these two is by
looking at customers' reactions to them.
Sustaining technologies are ones that a firm's major customers demand.
They're ones that they want.
They're ones that satisfy needs those customers know that they have.
Disruptive technologies on the other hand are technologies that might
offer interesting new capabilities, but
they're not capabilities that are valued by those existing customers.
The customers don't want them and so this sets up a very interesting dynamic.
To illustrate this, I'm going to take us through a diagram.
And in fact, this is a diagram that's adapted from Christensen's
original path breaking work.
The example's going to look at the development of the disk drive industry,
right?
One of the core technologies that powered revolution and
computers that happened from the 1970s to 1990s.
This is what Christensen's actually studied.
And so if you look at this diagram, we're simply going to have
performance on a vertical axis in time on a horizontal axis.
Now start by thinking about the market from the customer's perspective and
what customer's demand.
Performance in this case could be the amount of storage,
the speed with which the data is accessed.
We're going to keep it a little bit abstract, right?
But if you look at the arrow, right, this arrow shows that
customers demanded a certain level of performance initially.
And then overtime, that level of performance increased.
The customers found new ways to use the disk drives that disk drive
manufacturers were producing, and the market expanded.
So their demand shaped a trajectory,
the market trajectory as to what was needed, right?
What companies in the disk drive industry were being asked for by their customers?
Now, at the time that Christensen started his research window,
the first disk drives that he was looking at,
the first generation, were known as 14 inch disk drives.
That's the size of the circular platter that the data's stored on.
So 14 inches and these were the disk drives,
that disk drive manufactures like control data corporation were producing.
And if you notice where we have the dot placed over at the left,
that technology met customer needs.
Now overtime, as the technologies advanced the capabilities of those disk drive
manufacturers showed what Christiansen called the technology trajectory.
You can see that line is actually moving up more quickly than customer demands.
This is pretty common.
Now, the important point to note is that as disk drive
manufacturers improved their 14 inch disk drives.
And there were a number of major improvements that took a very significant
investment in technology, very significant engineering work.
Christiansen described these innovations as sustaining because these were ones
that improved performance on dimension storage, speed that customers demanded.
And the large disk drive manufacturers did just fine with this.
This is the point of sustaining technologies is that you're staying close
to your customer doing what your customer demands.
And as long as you're doing that, it doesn't matter if the elevation is radical
or incremental or competence destroying or competence sustaining.
Christensen said the key is what you're customer is looking for.
Okay, so now, let's talk about what ends up being the disruptive technology.
Now, the point is, it isn't disruptive at first.
What you see here that little dot, right,
represents the performance of a new kind of this drive.
One that only uses 8 inch platters.
Okay, now this has lower performance than the 14 inch disk drives.
All of the major disk drive manufactures explore this technology.
It had some advantages, right?
It's smaller, and so if space is important,
you can build a smaller disk drive.
But this is not a key dimension for
existing customers of the disk drive manufacturers, right?
These are customers who typically are using mainframe computers.
That are in a dedicated computer room, size is not that important.
So the key is that we've got a technology which is less capable in terms
of raw storage and speed.
It has something interesting, it's smaller, but
it's not what our customers demand.
Our customers stay with the 14 inch drives.
Now at this point we really have one of Christensen's
critical insights, the reaction of the existing disk drive
manufacturers was driven by their customers.
And in fact, what they were doing those disk drive manufacturers was what
managers are often told to do, right?
They're staying close to their customers and
using their customers' express needs to drive their technology strategy.
So they've backed off from developing those 8 inch disk drives.
Kept them in reserve, so to speak.
But this new technology didn't simply languish.
All right, there were in fact customers who could use the new smaller disk drives.
They weren't large customers these were mini computer makers such as DEC or
data general.
They were marketing smaller less expensive machines and the 8 inch technology here
matched their needs and was valuable to them because they weren't selling their
computers to customers who had an entire room to devote to the computer.
In fact, this is the period when I was actually working
in the computer industry as an entrepeneur.
And I remember as those smaller disk drives came out we were,
the company I was developing was selling computer systems to dentists, right?
Where space is at a premium, so those smaller disk drives were valuable.
But it was a tiny market, so it wasn't attractive.
That a market was not attractive to large disk drive manufacturers.
It was attractive to some of the smaller ones.
Some new ones who saw the potential.
