When Do New Technologies
Become Economically Feasible?
The Case of Electronic Products
A/Prof Jeffrey Funk
Division of Engineering and Technology Management
National University of Singapore
For information on other technologies, see http://www.slideshare.net/Funk98/presentations
Some Theory: Modeling
Improvements in Products
Learning curve
Costs fall as cumulative production rises
Assumes most improvements occur on factory floor
Experience curve
Costs fall and performance rises as cumulative production increases
Assumes that increasing cumulative production encourages product
and process R&D, thus leading to improvements
But which improvements are most prevalent?
Learning in factories, product and process R&D?
We analyzed technologies that experienced rapid rates of
improvement before commercial production began in order to
eliminate factory floor learning
Rapid Improvements with No Commercial
Production: How do the Improvements Occur?
Analyzed how improvements in cost and performance
occurred for 13 technologies that
experienced rapid improvements (>10%/year)
without commercial production
13 technologies
Organic transistors, solar cells, LEDs; Quantum dot displays and
solar cells; Superconducting Josephson Junctions, Quantum
computers; Superconducting cables, Carbon nano-tube
transistors; Non-volatile memory: PRAM, MRAM, FeRAM, ReRAM
Most common methods of improvement
New materials (and new processes for them)
Reductions in scale of featuresSource: Funk J and Magee C 2015. Rapid Improvements with No Commercial Production: how do the improvements occur? Research Policy
Are there other Technologies
that Contradict the Learning
and Experience Curves?
Rapid improvements occur but…
Improvements in assembly or
product and process R&D for the
final product cannot be the
explanations for the rapid
improvements
What Happens When Cost of Standard
Components are far Higher than Cost
of Assembly Operations?
Low contribution of assembly to total costs means that learning in assembly or process R&D for assembly cannot be key sources of improvements
Standard components are used
by multiple suppliers of end products and/or
in different types of products from the same (or different) end product supplier
Large contribution of standard components
Means that opportunities for product R&D are limited
Improvements in the end products come mostly from improvements in the standard components

Cost Breakdown for Electronic Products
1 Values as a percent of total and material costs
2 Excludes mechanical components, printed circuit boards, and passive components
Preliminary Conclusions
Cost of assembly is very low
Improvements in assembly operations or process R&D
for assembly cannot be important sources of cost
reductions
Contribution of standard components is very high
Design space and opportunities for product R&D are
limited
Demand for the standard components are not driven
by a single end product
What is Driving the Improvements?
Let’s look in more detail at the standard components
in these products

Interpretation
A small number of standard components play important role in electronic products and improvements in them
Enable improvements
Determine new types of functions
This is why many people emphasize Moore’s Law
Because it is really changing our world
To investigate the role of these components in more detail, we now consider two types of products

For the first iPhone
What Levels of Performance and cost
were needed in each Component
before the iPhone was economically
feasible?
Touch Screen and Overall Display
DRAM and Flash Memory
Microprocessors
Can we use such an analysis to better
understand the future?
Let’s look at flash memory
The 4GB iPhone could store
760 songs, 4000 pictures (4 megapixel JPEG),
four hours of video, or 100 apps/games, or
some combination of them
Equal usage
190 songs
1000 pictures
one hour of video
25 apps/games
Was 4GB of flash memory necessary, or would
less have been sufficient?
Sensitivity Analysis of Flash Memory Price
Cost of iPhone 5 varied from $207 to $238 depending
on flash memory capacity
16GB, 32GB, or 64GB
For iPhone 4s, costs range from $196 to $254 for same
range in flash memory
For iPhone 3GS, 16GB of flash memory are $24 thus
suggesting costs for same change in capacity would
range from $179 to $251
In percentage terms, same changes in flash memory
capacity led to increase of 40% in iPhone 3GS and
increase of only 15% in iPhone 5
Interpretation of Previous Slides
Improvements in flash memory were
essential for the iPhone to become
economically feasible
Similar analyses could be done for
microprocessors and displays
And would probably show similar results

For the first iPad
What Levels of Performance and cost were
needed in each Component before the iPad
was economically feasible?
Touch Screen and Overall Display
Memory
Microprocessors
Can we use such an analysis to better
understand the future?
Let’s look at display, memory and
microprocessors
For the first iPad (2)
Touch Screen and Overall Display
Much larger and thus more expensive than one for iPhone – probably was a bottleneck
But falling cost (12%), price 20%) of displays
Memory and microprocessors
Cost of iPad Air varies from $274 to $331 depending on flash memory capacity (16GB, 32GB, 64GB) and whether cellular processor is included
For earlier iPads
From $316 to $406
From $229 to $346
Percentages for memory and microprocessors drop from 50% in first iPad to 21% in iPad Air
Did the first iPad need a cellular processor?
Interpretation of Previous
Slides
Improvements in displays, memory and
microprocessors were essential for the
iPad to become economically feasible
Let’s now think about the future – for
smart phones, what will be next?
For Smart Phones, What will be Next?
What components are experiencing rapid
improvements?
Can they tell us something about the “next big thing”
Improvements will probably continue in
Microprocessor, memory and other ICs
MEMS, bio-electronic ICs
Displays including flexible ones
Lasers, LEDs, photo-sensors, and other sensors
Speeds of cellular networks and WiFi
New forms of user interfaces (gesture, touch)
Open source software is becoming more available
What will be Next? (1)
New features, perhaps for high-end phones
Health care: phones monitors health (heart rate, brain wave, blood pressure) using sensors
Home automation: use phones to control homes
Better navigation, sharing economy
Engineering assistant: environmental data (temperature, pressure, air and water quality) and also data from satellites
Different phones for different applications?
One phone does everything?
Multiple segments each with multiple applications for phone?
Specific phones must be defined for specific users
What will be Next? (2)New forms of computers
Wearable computing?
Smart watches?
Wrist displays?
Google glasses or something similar?

Contribution of “Standard Components” to Costs
of Selected Electronic Products
Can any of these components be eliminated?
Are there improvements in components and/or
technological trends that can help us think
about components to eliminate?
What will be Next? (3) Can microprocessors and memory be eliminated to
create low-end phones that bypass network providers (SingTel, StarHub)
Lower cost phones
Lower cost services
Cellular processors are eliminated as WiFi becomes more available?
If WiFi is main connection and it works good enough
Can we reduce memory capacity?
Can we reduced performance of application processor?
Lower resolution cameras, displays, and other components will also reduce costs
How might open source software enable lower costs?

How About the Other 8 Products? How might improvements in electronic components
change the other products that were briefly mentioned?
Tablet computers, eBook Readers
Game consoles, MP3 Players
Televisions, Internet TVs, Google glasses
All of these products are being improved with new
electronic components
WiFi may eliminate cellular processors in tablet computers
and reduce memory in game consoles
What will these products become?
Will they become more important in our lives?
Or will they disappear as their functions are absorbed
by other products?
How About Still Other Products (2)
Improvements in computers: logistics, free routing if aircraft,
pre-fab housing, computer assisted-doctors, Big Data, online
universities
Improvements in ICs, MEMS, GPS, other electronic components:
Smart homes, Internet of Things, Drones, Autonomous Vehicles,
Sharing economy including shared bicycles, GPS for buses
Improvements in displays and ICs; rolled displays, wrist displays,
wearable devices
Improvements in microprocessors and power electronics: cheaper
electric vehicle chargers that enable more frequent recharging
and thus reduce the need for high energy storage batteries
Many of these products can contribute towards sustainability
These things and more are discussed in MT5009, Analyzing Hi-Tech
Opportunities (for more info, see http://www.slideshare.net/Funk98/presentations)
Comments on Learning and Invention
When standard components contribute much more to costs than do assembly operations and they experience rapid improvements
Factory floor learning and process R&D for assembly are not important sources of improvements
Product design opportunities are also limited since most of the components are standard ones
Demand for the standard components is driven by multiple products and thus the volumes for a new product have little impact on the standard components
Instead, learning revolves around the standard components and how to use them to introduce better products
Comments on Learning and Invention (2)
Contrast this with automobiles
Discussions of automobiles emphasize speed,
acceleration, fuel economy, smoothness,
quietness, and interior and exterior aesthetics,
measures
These depend more on overall product and
process design than any one component
Even speed, acceleration, and fuel economy
depend on many design factors
and not just the engine design since they involve
the aerodynamics and weight of the overall
automobile
Comments on Learning and Invention (3)
When standard components contribute much
more to costs than do assembly operations
and they experience rapid improvements
Monitoring these components is essential for
“inventing” and developing new products
What components are in the new product?
What levels of performance and cost are
needed in this product and in its components
before the product will become economically
feasible?
