Software Costing

There is an old saying that goes something like this: “hardware is almost free and comes from China; but software is actually free and comes from India”. Actually not such on old saying, and certainly not true. But we do see signs of this myth being alive and well when providing project pricing and estimates for new clients. I covered some of this in Software Estimation.

Software Estimation

Software Estimation

This was about how to try and work out a Software Development Budget in advance. Including forgetting that the entire Software Development Process involves more than just typing. So is it possible to know what it really  costs from real world (non-imaginary) data?

Software Cost

The answer is that it is. My thanks got to VDC Research who recently did a survey of Embedded Developers and made the data available to subscribers of The Embedded Muse, a software development newsletter authored by Jack Ganssle. If you develop software, especially for Embedded Systems, I recommend you sign up if you aren’t already a subscriber.

Here is a summary of some statistics that gave me insights into real Software Development Costs.

Average Median
Project Team Members 19 7
Project Cost $27,000,000 $250,000
Lines of Code 627,000 20,000

So that is a big spread. Our projects are often below the median level shown here so I was interested to work out what these statistics translate to in cost. The $ are all USD$. And the large lines of code average probably represents larger projects using a major Operating System such as Linux as part of the project.

Cost per team member Cost per line of code
Average $1,421,052 $43.06
Median $35,714 $12.50

My first thought is that we don’t charge enough if these are industry typical figures. A bit more thinking shows the process costs of much larger systems. As far as I know there would be few software developers actually getting $1M for their part in the project. And there will be tools costs also included. The statistic missing for me was the duration the money was spent over. We typically budget $5 per line of code for larger projects (20K lines is a decent sized project for a small embedded system) and $2.50 for smaller ones (say 5K lines of code of less).

So there you have a really rough way of estimating cost based on Lines of Code and number of Software Developers involved.

The above is a very small example of the data collected by VDC Research so consider signing up if you want to see all of it.

Software Lines of Code

Software Lines of Code, or LOC, is only one measure of a project. There is much more to consider. We had a recent project where we were asked to fix 50K lines of code for a product that was proving unreliable. So I ran RSM over the top of it to get the average Cylcomatic Complexity and got 6.2! Those who know what that means probably have no idea how you could write code that hard to debug. And no, it wasn’t lots of switch statements. So is the correct answer $250K at $5 per line of code for a complete rewrite?

The answer is a resounding “NO”!

And the reason is because we redesigned the control flow and changed the UI to a table driven design and reduced a spaghetti mess of 50K lines of code down to 10K lines of cleanly designed code. Which is a budget more like $50K. In this case, it was much more cost effective to redesign from scratch than to try and rescue it. We also fixed the hardware design as that was in part responsible for the unreliability.

So the other answer is that good requirements analysis and good design will reduce Software Cost.

Power Supply Specification

The idea for this post came from a discussion in IEEE Collabratec on how to design a Power Supply. The question of how to design a Power Supply seems innocuous enough until you really start to think back on past Power Supply designs. I was originally concerned that this was a student wanting someone else to do their coursework assignment for them but the discussion progressed into something quite useful. Here is what I posted after getting the following specification:

  • Output Voltage: -300VDC
  • Output current: 0.5-20mA
  • Tolerance: 30Volts
  • Input Voltage: 220-240 AC

Analysing Requirements

Hi …

is this project part of your course work?

The reason for this question is that the intent of coursework is to help you come to grips with what you are being taught and learn it from a practical perspective as well. Among other things, this helps a lot with retention.

I run a company that designs products for other people. I only employ graduate engineers who have demonstrated the capacity (though their academic results) and inclination (through their having done their own projects and learned how to use the teaching they have received) to do engineering and to be capable of quickly learning all the things they can’t teach in a course.

So if it is coursework, what subject is it part of?

Because if they want you to design a switching mode power supply, that is very different to an AC rectified transformer design.

You also need to be careful with a design assignment like this (coursework or a product that will be manufactured) because it is capable of killing you if you don’t use good safety practices.

I’ll assume your tolerance figure is +/-30V = +/-10% of -300VDC. So the voltage at its maximum excursion from 0V could be -330. And the maximum current is 20mA. This is 6.6W of power so it will get hot. And again, there is enough voltage to kill you.

If it is for a commercial product, then there are usually other constraints. Here are some of the questions I would be asking:

  • The input voltage range is specified as 220VAC to 240VAC but it is normal to allow for short term transients. So does the output voltage have to be clamped during mains transients?
  • Is soft start required?
  • How quickly must it respond to load transients?
  • What is the load and how much does it vary?
  • Does the input stage need to be designed so that it keeps harmonics and power factor under control (this is a legal requirement for some product types)?
  • Is there a maximum size?
  • What is the design life and/or MTBF (Mean Time Between Failure)?
  • Is fan forced convection allowed, and if so, is that even a good idea because of the MTBF or because it goes inside a sealed cabinet)?
  • What is the maximum temperature rise allowed on any of the outside surfaces?
  • What type of connections for the input and output voltages?
  • What has to happen if the output goes short circuit or open circuit (you had a minimum current of 0.5mA so is there a minimum external load and what is allowed to happen if that isn’t there)?
  • What is the environmental specification (0->70C, -20->85C, -40->85C etc)?
  • Is there a manufactured cost target?
  • Do you have to simulate it only, or are you building one and proving the performance?
  • Are there any special safety or EMC compliance requirements for this application?

And there are lots of other questions like this for a real product design.

So regardless of the reason for the design, understanding the intent of the exercise is important to delivering a satisfactory outcome.
This is one of the reasons engineering is not easy. We create the future. Others say that as well. But we also create the infrastructure and products that make a more advance future possible. And there are always lots of constraints.

I hope that has maybe encouraged you to think a bit deeper about the question. It is unlikely you will solve a problem you don’t fully understand. And an answer you don’t work through for yourself will probably not expand you understanding.

Making Music is Creative

Making music is a creative process. At every level. There is not only composing and playing, but there is the instruments themselves and also how we record and play back music. Technology and creativity abound at every level.

I’m a musician. That is how I ended up in Electronics Engineering. I even wrote a blog piece about how Music Electronics was where my passion for creating new electronics devices all began.

Miller Puckette

I learned something new this week about music creation. I use Ableton Live as my sequencer and it incorporates a product from Cycling 74 called MaxMax was created by Miller Puckette quite a while ago. So I see another soul keen to push the boundaries of what is possible and was fascinated to read his history. Everything from Teaching Music at UCSD to creating music software like Max in 1988, its successor starting around 1996 which is Pure Data, or Pd as it is usually abbreviated, and which was set up to be an open source project so others could contribute and it wasn’t locked down by commercial constraints like Max is.

Miller Puckette - musician and music technology creator

Miller Puckette

I was also pleased to hear that Miller Puckette continues to perform music. This is something I also enjoy.

The only way to understand what is possible with tools like Pd is to see it in action. Enjoy.

Did you notice that the player on the left is moving his hands on a cloth covered platform. This is being tracked by a camera and the hand movements are used to trigger notes and other controllers and effects. You can reach him at Jaime E Oliver and the cellist accompanying him is Michael Nicholas.

PdCon

And if you found that interesting, then check out the concert video from PdCon16~ . That’s right, Pd has its own conference.

The first video has Miller Puckette as a contributor.

And the last one also has Miller Puckette as part of a duo. This is all very avant-garde yet the degree of expression possible is amazing.

Self Thinking Robots

Although that is what they are called, I’m not convinced it is actually thinking. It certainly wouldn’t pass the Turing Test. But I thought this showed a good comparison as to how far the state of the art has come.

Lets start off with a look at the very beginnings of software controlled autonomy.

Shakey

Above we have the first Autonomous Robot, Shakey, that could learn about its surroundings and adapt. Today any Roomba or equivalent can do better. But this is the same time period as we first went to the moon. And I believe my wrist watch currently has more computing power in it than the whole of the 1960s possessed.

Handle

And below we have an example of the latest offerings from Boston Dynamics named Handle.

Quite a bit different in capability. This might still be a 1 word robot by name, but you can see a lot of possibilities that weren’t even on the radar back in 1968.

Industry 4.0 and Bosch Australia

This is the first of a 2 part past covering the SEBN (South East Business Networks) business breakfast just before Christmas 2016. The first speaker was Gavin Smith of Bosch Australia. His talk was title “Life After Auto” and here is my summary.

Gavin Smith - Bosch Australia

Gavin Smith – Bosch Australia

In the 1960s you could make anything in Australia because the import tariffs were high and we were a long way away from the rest of the world. But by 2008 all that had changed. Although Robert Bosch is the largest tier 1 automotive supplier in the world, and the largest automotive company that doesn’t assemble vehicles, the original Bosch Australia factory is no longer there and a new one built and they are about to expand again.

So there is a lot of change. He also quoted Jack Welsh of GE fame: “If the rate of change on the outside exceeds the rate of change on the inside, the end is near”!

High volume no longer has to be a lot of the same thing. They are now doing high mix electronics manufacture and are about expand that as they have run out of capacity. This follows the Industry 4.0 model rather than traditional manufacturing.  The design team is also expanding s they are now do bespoke product design with the intention of making them locally.

Bosch are also keeping track of the following Megatrends:

  • Demography
  • Urbanisation
  • Energy and climate
  • Connectivity
Bosch - Megatrends

Bosch – Megatrends

And all of this relies heavily on IoT (Internet of Things) devices and Big Data. To be a global supply chain player or to have a modern product you will have to have connectivity and visibility of every part of your process and your supply chain as well. And for Industry 4.0 you will especially need it for inside the factory. This is already happening.

Robert Bosch are also looking at incubation for new ideas internally and also externally. This is a great idea and something we are also doing with both clients and prospects.

They are also looking to attract more women into STEM (Science, Technology, Engineering and Maths). Something I am also keen to see happen.

Industry 4.0 example

Gavin finished with a video that showed just how streamlined the Design to Manufacture path could become. Something essential to the realisation of a true Industry 4.0 mass customisation.

While it is worth remembering that some of the above is a view of how the Industry 4.0 future could be, rather than what today looks like, Europe have been pursuing this trend for 15 years. So we have quite a bit of conceptual catching up to do as well as implementation capability. And we need to start early which is why the Casey Tech School project and Schools of the Future are so important.

IoT Interoperability

There are several big issues with IoT. The primary 2 are Security and Interoperability. We have tackled IoT Security and so this post looks at how different devices and systems can work together. This is Interoperability.

The first thing to understand, is that middle ware providers like IBM do not want you to be able to exchange data independently of them. They want you captive to their ecosystem. They make money from you having to pay them for continued access to your own data. This inherently works against one aspect of interoperability.

IEEE has put together a useful introduction which you can access at Interoperability in the Internet of Things. This includes a useful audio explanation and detailed articles on each area plus sample projects.

IoT Interoperability

IoT InteroperabilityIoT

The IoT vision is for a highly connected and interoperable system but most systems do not interoperate well. And standards development is still ongoing which means there is no agreement in sight.

To explore further, there are some excellent resources at:

As usual, Europe seems to be doing more to foster unity and collaboration and has many excellent projects to help this. The Unify IoT project has published results which are freely available. They conclude that there are 300 IoT frameworks in use and 20 of them are quite popular. But no standards are expected anytime soon and the lack of standardisation is a big impediment to getting the full benefit from the technology.

Brain Scanning

The ability to scan details of the brain is a common theme of both science fiction and also modern medicine’s wish list. So just how likely is it that we will be able to do that anytime soon?

Check out this image captured by a project focused on capturing the Wiring Diagram of the Brain.

MRI Brain Activity Scan

MRI Brain Activity Scan

Well in June 2016 researchers showed that they could uniquely identify a person with 99% confidence based purely on their brain scan. This uses newly developed magnetic resonance imaging equipment that has come out of the Human Connectome Project and can also show the following:

  • how you will perform on an IQ test
  • how you will perform on a memory task
  • how you will perform on a reading task

That seems pretty specific.

What we have learnt is that while we are all unique, there are some common elements we can use to define capabilities. We are still a long way from Gattaca and I am OK with that.

Digital Tomorrow is Today

The most recent Casey Cardinia Business Group breakfast heard from Chris Riddell, futurist. This is a summary of what he said.

Chris Riddell - Futurist

Chris Riddell – Futurist

The future is already here. The digital revolution has happened. So what about tomorrow?

This is the question Chris posed to the room at the start of his presentation.

Chris asserts that the technological revolution has already happened. Now it is Velocity that counts. So what does Velocity mean?
In Software Development, Velocity refers to the rate with which you are completing a project. If Velocity is too low, you will not finish on time. Ideally Velocity is above the original planned value and you will deliver ahead of schedule. At the very least, this allows you time to test comprehensively. Projects running late often compromise on test in order to save time. This tactic usually adds time in the long run.

His first example was OTTO. This is a start-up of ex Google employees who are developing self-driving track technology that can be retrofitted to existing trucks. So you don’t need to design a new vehicle, you can add their system to your existing fleet. They have early adopted product in the market (delivering beer via self-driving trucks) and hope to be fully market ready in 9 months. And uber bought OTTO. This rapid time to market is an example of the increasing Velocity available today.

OTTO self-driving truck

OTTO self-driving truck

A local example we are working with is Maintabase. This is a Melbourne based start-up that came to us 2 months ago with some “off the shelf” hardware to try and configure it as a demonstration of their asset management concept where you can monitor machine cycle and operating time automatically and identify when maintenance points will be reached. Like OTTO, this can be retrofitted to any existing machine. They were trying to use “off the shelf hardware” for good reason; low development cost. However the hardware was difficult to configure and use, not very flexible, and ultimately not what they wanted in a final product. It was never going to do what they needed and was only ever an interim measure. So we created the product they need and they are launching it at Future Assembly in the IoT Category. See Future Assembly – IoT – Maintabase for more details. So idea to launch in 8 weeks!

And then there is Tesla who have reinvented the modern passenger automobile and already offer autonomous cars.

And now a medical example. 23 and Me will send you a DNA kit. You provide a saliva sample in the test tube they provide. They then send you a detailed report describing your genetic ancestry, what health issues you will expect have in the future and even what kind of children you will have with your partner (you need 2 samples for that). This was banned in the USA due to concerns about how to regulate it so they moved to Europe and launched there. Now they are also able to operate in the USA. 5 years ago a service like this would have been prohibitively expensive. Now it is a very affordable tool to allow you to manage your life better.

23 and Me - Welcome to You

23 and Me – Welcome to You

We also see the huge burst of activity in Wearables that allow you to quantify things like quality of sleep, activity level and a whole range of health and other indicators. The Quantified Self requires measurement and these devices do a good deal of that already.

Lean Digital Start-Up

Computing technology is also changing so rapidly that you can do a hugely scalable start-up in a shed. This is technology going full circle. HP started in a shed. So did Google and Apple. The shed may become the new business launch model.

This allows a new class of business opportunities lumped under the banner of the Lean Start-Up. I’ve added “Digital” to the mix because there is a lot of emphasis now on being able to scale quickly. So we have the Lean Digital Start-Up. So low investment, low risk, potentially huge upside, potentially scalable. The failure rate of Lean Digital Start-Ups is unfortunately also huge. About 25 times the failure rate of conventional businesses. The risk due to failure is much lower and they can pivot rapidly. This is Agile applied to the Business Model.

Old world businesses are like huge plantations and have a specific focus and everything is about optimising that focal point. By comparison, the new business paradigm is like hacking your way through a rain forest looking for a breakthrough plant or animal that holds the cure to something incurable. The latter is a much more chaotic process and results are unpredictable.
Access to technology means that even mobile phone calls and SMS are old hat and is all about video, high speed data sharing and experience.

The Future – What Next?

BMW have just celebrated 100 years in business. That is a great achievement. If you go back 50 years, it was all about the product, the technology, the reliability. Today it is all about the experience. And they are talking about selling transportation services rather than vehicles in 10 years time.

Super Fluidity is now the norm. You can transfer data almost instantly to anywhere in the world. Today you can design a product , send the file somewhere else on the planet and have it 3D printed . You can now 3D print food. Oreos can be custom designed by you and then made for you and shipped to your address.

Why is Google self driving cars happening? Google do search and other data stuff. The answer from Google is that a driver-less car is a mechanical problem that needs an information solution. And Google are an information solution company.

Why is Lego still in business? It is a plastic block. Easy to copy and many have done it. Yet today they are the most influential toy company in the world. Everything is about the user. You can design your own kit, select the blocks, buy it and have it delivered to your door. You can build it on screen, have it 3D rendered and sent to your device to show or share with your friends.

Apple have enough cash on their books to pay out Greece’s national debt 3 times over and still run their business for a year even with no sales. And they did it by making their product easy to use and putting a full ecosystem together to support the user.

Air bnb, uber, Spotify and many other companies are leveraging great user experiences and offering great value.

We are headed into an era of no screens, augmented reality and where the world is your screen and data is your overlay.

Pretty exciting times lay ahead as we catch up with the capability the Digital Revolution already lays before us.

IoT Security

The Internet of Things, or IoT, is a pivotal component of the future and is driving initiatives from Smart Cities through Ubiquitous Computing and Augmented Reality. Of course the next step up from Smart Cities is a Smarter Planet. But we aren’t at Smart Cities yet.

An enabling technology like IoT can also have roadblocks to adoption. The principal ones being addressed now are:

  • power consumption
  • cost of goods
  • size
  • security

The biggest issue right now is IoT Security. Recent DDoS (Distributed Denial of Service) attacks have used IoT Devices as the attack launchers. They are being selected because many have weaker security than fully fledged computing devices.

DDoS or Distributed Denial of Service

DDoS or Distributed Denial of Service

In a recent article on IEEE Spectrum on the Path to IoT Security it is argued that IoT Manufacturers must take responsibility and not leave it up to end users. There is also a role of industry standards however no clear set of standards have yet been agreed. So although 2016 is the Year of IoT, with this being the single biggest category of product shipped, it is still very early days where things like IoT Security and IoT Interoperability are concerned.

IoT Security versus Software Security

This is not a new dilemma. Software Security is always important and it becomes increasingly important as Internet Communicating IoT Devices become more widespread. One apparent assumption underlying all this is that an IoT Device must be a fully IP Stack capable platform. That is not necessarily the case. In the video I shared about our Water Metering Remote Telemetry project one thing I didn’t mention is that the data stream is all driven from the IoT Device. There is nothing to log into. You can’t patch it with a Windows, Linux or other OS patch to override its function. It is not capable of being used in a DDoS attack because you can’t get to anything in it that can do that. So it is inherently secure against that form of risk.

Internet of Things Cconnectivity

Internet of Things Connectivity

However there are other risks. Nick Hunn has an insightful piece on Wireless Security for IoT where he argues that we are declaring security is present while having no evidence of proving it. That article is a little dated but the basic tenets still seem to apply. Just because a manufacturer or industry alliance states they have addressed security, it doesn’t make it automatically true.

So IoT Security is Software Security with the added component of protecting the physical hardware.

IoT Security in the Future

We still don’t have standards, so for now, individual device manufacturers and alliance members will need to ensure they have adequate security out of the box. The level of security required is determined by the importance of the data, either its security against unauthorised access, or its integrity against falsification. And at the asset level, its proof against either being disabled or used as an attack vector.

As an example, I am personally not so concerned if a hacker can find out how much electricity use my smart meter is reporting. Unless they get time of day usage and can correlate with other data sources to work out in advance when we aren’t home so they can rob us. My energy provider probably cares more about this data for all its customers coming into a competitors hands. Or maybe not. But I do care that I don’t get an outrageous bill because they were able to send fake data for my account to a server.

And energy grid managers care about usage data and Smart Meter appliance management being used to crash an entire electricity grid!

In the case of the Water Metering Remote Telemetry project I care that it remains online and working because otherwise someone will have to travel a long way to fix it. We have a facility in Gilgandra that is 892Km away as the crow flies. It will take a full day to get there and then another to back again. So I want it to be proof against some hacker disabling its communication ability. Since it has a physical antenna, I do care about that being hard to break. So some of these devices are put above normal reach and everything is inside a secure plastic case including the antenna. And our customer wants to know the reported water usage is correct. This means no missing data, and no incorrect data. They use the data to bill their customers.

One simple way to mess up data is a Replay Attack. If you can intercept and copy a data transmission, then you can play back that transmission any time you want to. You don’t even have to understand the content, the encryption, anything. Simply capture a HTTP POST or GET and replay it. Why does this matter? Because if the data transmitted is the volume of water used since the last report, then every time you play it back, you add to someone’s water bill. Or you distort the level of water the system believes is in a tank or reservoir. You can protect against these attacks in a number of ways but you have to consider the need to protect against them first of all.

There is a large volume of material on this topic. Here are some additional articles you might find useful for broadening your perspective on this topic:

I’m sure you won’t find it hard to search out a lot more articles. Just consider this. Once it has an Internet connection, any device can access anywhere in the world. And most firewalls protect against incoming attacks. A corrupted device on the inside can get out any time it wants to.

Internet of Things Global Reach

And if you want a really interesting view of what this could be like 10 years from now, I recommend reading Rainbow’s End by Vernor Vinge. Enjoy. And this isn’t my first reference to this book because I think it is fairly prescient in its exploration of a most probable future.

DSLR or Digital Single Lens Reflex Camera

Ignoring the play on words, the light camera is a major breakthrough in the use of multiple optical viewpoint cameras to create synthetic images that can be taken with something the size of a smart phone and rivals DSLR Camera photographs.

And spoiler alert, I’m getting one as soon as I can. Read on to find out why.

I enjoy photography and appreciate the balance between the size and convenience of my phone camera and the control and quality of image possible in my DSLR (Digital Single Lens Reflex) camera.

Lets look at how a DSLR camera works. This image is by en:User:Cburnett – Own work with Inkscape based on Image:Slr-cross-section.png, CC BY-SA 3.0, Link.

Single Lens Reflex Camera Cross Section

SLR Camera Cross Section

The photographer can see the subject before taking an image by the mirror. When taking an image the mirror will swing up and light will go to the sensor instead.

  1. Camera lens
  2. Reflex mirror
  3. Focal-plane shutter
  4. Image sensor
  5. Matte focusing screen
  6. Condenser lens
  7. Pentaprism/pentamirror
  8. Viewfinder eyepiece

For a Film SLR camera the sensor is the film. For the DSLR Camera the sensor is a digital image sensor CCD or Charge Coupled Device. These cameras use precision ground lenses and are capable of high levels of control and image quality. They also don’t fit in your pocket unless you have a very large one.

The Light Camera

Light - a new camera concept

Light – a new camera concept

I am very grateful to Dr Rajiv Laroia who co-founded Light. Not only has he developed a breakthrough concept in portable digital photography, but he has been very open about how he went about it and how it works. This is an excellent example of the new Collaboration landscape we now work in. He took his idea to experts to validate it rather than hiding it and hoping no-one would steal it.

IEEE Spectrum have a very detailed article Inside the Development of Light which outlines the whole journey. There are several stand out points here:

  • he solved a problem he had – it represented a practical need he understood
  • he got expert advice early
  • it required a significant shift from the best of breed technology in place now
  • he knows his first version is just that
  • there is a long term product strategy in place
  • he is teaching the world how to do it so that he has first mover advantage rather than a monopoly

The last point is interesting for me. The days of monopolies are coming to an end. The days where a Brand could overcome deficiencies in an offering aren’t yet over but they are fading. Today you can source reviews from peers and industry forums and a Brand can’t as easily dominate a market just by reputation or marketing blurb. The products have to be as good as the Brand claims they are.

Dr Rajiv Laroia - cofounder of Light

Dr Rajiv Laroia – co-founder of Light

So back to Light. Dr Rajiv Laroia has started something we will all benefit from. The concept is brilliant and the results and funding are in place to make is commercially successful.

Will we see it in a smart phone soon?  I can see cut down versions of this concept being deployable in the very near future. The processing power is the challenge in a low power hand held device that is also doing cellular communications. So battery life versus quick availability of the finished pictures is the trade-off right now.

Is it doable in the long run? Absolutely!

Light in Action

Here are some videos covering the development journey, the first commercial version and the use of the camera.
