A series of three presentations were delivered at the NZ Health Congress by Jono Jones (Locus Research), Professor Simon Fraser (Victoria University), and Timothy Allan (Locus Research). On the topics of FEA and Analysis in Healthcare, Additive and Rapid Manufacturing and Lean Startup
From this presentation, you will learn why mistakes continue to happen within your organization even with preventative solutions like training, wikis, checklists, and manuals. You'll learn why those solutions aren't effective and what you need to do to become a true learning organization that can effectively prevent mistakes from happening again.
The thousands of others around the globe that have adopted this approach have a competitive advantage over their competition because their recurring mistakes are eliminated, costs are cut, output quality is improved, and workers have more time to focus on continuous improvement and can spend less time putting out fires!

Conference description:
How will Project Data Analytics (PDA) change project controls in the future?
We all know that one of the key elements to successful project delivery is a robust project control system. But while many of these processes are well established, the ability to make maximum use of the resulting data has often proved challenging. But this is changing.
For those involved in project controls in any way, this conference shared the latest practical uses of PDA as well as a glimpse into the future!
The conference provided insight from a range of PDA practitioners as well as feedback from a recent Delphi research study on the topic.
PDA will be key to the profession as we look forwards, make sure you help us shape it to deliver what we really need.

Chinese factory managers often say things such as “these three people caused this issue”, “it is their fault”, and “these are human mistakes and they can’t be avoided”. However, one could argue that the factory’s systems are at fault. And who can develop and implement systems? The managers themselves, not their employees.
Which systems need to be put in place to avoid mistakes and improve product quality? Let’s look into 7 mistake proofing approaches that work...

Some years ago, Eric Ries, Steve Blank and others initiated The Lean Startup movement. The Lean Startup is a movement, an inspiration, a set of principles and practices that any entrepreneur initiating a startup would be well advised to follow.
Projecting myself into it, I think that if I had read Ries' book before, or even better Blank's book, I would maybe own my own company today, around AirXCell or another product, instead of being disgusted and honestly not considering it for the near future.
In addition to giving a pretty important set of principles when it comes to creating and running a startup, The Lean Startup also implies an extended set of Engineering practices, especially software engineering practices.

A guide to generating insight through research for product development
Research is the primary risk management tool you have in product development. It is also the biggest driver of insight and breakthrough ideas. The challenge many people face is doing it in a way that retains creativity and objectivity. Balancing the technical and human centred approaches can be a challenge but the results are worth it.
Understanding people’s needs and requirements is the key to unlocking insights, but is not enough on its own. It must be coupled with a broader understanding of the
business, product, and technical context; the product system.
This presentation sets out a practical approach to undertaking research for product development. It provides guiding principles for primary research and how to interpret information and create insights. Our approach has been developed from a range of other approaches and our own experiences. It provides a common approach that can be applied across all types of research.

Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.

Lean Startup
A different approach to commercialisation
PRESENTED BY: Timothy Allan
TO: Health Congress 2013
DATE: 25.06.13
19. Re-Track
So we have heard about:
⧁ New methods of development & analysis.
⧁ New approaches to the rapidly developing wave of
manufacturing methods.
⧁ Do we need a new business model?
20. The Lean Start-up
This can apply to both established businesses & new
business ~ it is an approach.
⧁ Originally proposed in 2008 by Eric Ries.
⧁ Based on simple principles.
⧁ Uses the 'Minimum Viable Product' MVP concept.
⧁ Is heavily based on the principles of Lean.
21. Back to Lean
Lean is a concept that is well established in New
Zealand manufacturing.
⧁ Create Flow
⧁ Eliminate Waste
⧁ Flexibility ~ Sensitive to Change
⧁ Pull - Processing
⧁ Customer Oriented (not push)
23. Learning First
A method of product development.
⧁ Drives development of knowledge initially not just
products
⧁ Knowledge is then used to develop products
⧁ Wright Brothers to Team New Zealand.
⧁ Iterative in nature.
24.
25. Minimum Viable Product (MVP)
The cornerstone of the Lean Startup
⧁ Does not mean 'Minimal' product.
⧁ An iterative process of idea generation,
prototyping, presentation, data collection, analysis
and learning.
⧁ Delivers the features that enable a product to be
deployed an no more.
26. Build-Measure-Learn
"The fundamental activity of a startup is to turn ideas
into products, measure how customers respond, and
then learn whether to pivot or persevere".
"All successful startup processes should be
geared to accelerate that feedback loop".
~ Eric Ries

28. Healthcare's Challenge
There are some key issues that have to be considered
at the start of the process.
⧁ IP - your investment requires you to protect it.
⧁ Process - emerging compliance requires you to
follow a structured process.
⧁ MVP - can you get by with a minimum level when
you are dealing with medical devices, software and
pharmaceuticals?
⧁ Access to patients/clinicians- can be hard if your
just starting out.
29. IP
It is possible to protect in an iterative cycle.
⧁ File pro-actively in advance of disclosure.
⧁ Create a small group of users where disclosure
can be adequately controlled.
⧁ Decide what is important, rather than trying to
protect everything.
⧁ Place a commercial value on speed to market.
30. Process
An iterative process can still fall within a structured
development process.
⧁ Build, measure, learn is a principal which should
be a core part of NPD activity.
⧁ Document all activity and outcomes and build in
higher level reviews.
⧁ Create a Meta Structure above your iterations to
document and drive change and improvement.
31. MVP
'Minimum Viable Product' is as important in medical as
in other applications.
⧁ Don't polish the silverware.
⧁ Focus on the essential and critical elements and
drive into the feedback loop as quickly as possible.
⧁ Have a culture that accepts change is ok and it
sometimes has to be significant.
⧁ Build releases into your development timeline
rather than waiting to finish.
32. All Together
⧁ Simulation/Analysis - can speed up iterations
and reduce waste.
⧁ Rapid and Additive Manufacturing - can produce
products more quickly after analysis.
⧁ Lean Startup - pushes you to market quickly and
forces you into a fast feedback loop.
Editor's Notes
Finite element analysis is the computational approach to solving complex problems with boundary conditions by dividing it into many small sub-functions and solving each in turn. This is commonly used to analyse physical performance and integrity of manufactured parts before commitment to production to provide surety the part will perform as required Used for part design optimization such as minimizing weight while maximising performance. Software such as ANSYS or FEMAP import parametric 3D file from CAD for the analysis
A virtual mesh is applied to the model and the intersection points are called nodes. Material characteristics and parameters are applied to the nodes to simulate the material. Bed slat shoe for the Evolution sleep system This was a productionisation and Santoprene - Hytrel, half weight. Same feel
FDA encouraging simulation as parts of submission packages. To support animal, bench and human testing FEA is a requirement to achieve FDA approval for many devices that are implanted in the body – e.g. stents Recognised that better results can be derived from computational process
Finite element modelling and analysis is increasingly being used in medical device developments. This is an example by Bausch and Lomb the contact lens and eye health specialist who used FEA in a biomedical context to develop highly flexible intraocular lenses (IOL) for cataract surgery. During cataract surgery a small incision is made in the cornea and the lens is inserted. Bausch and Lomb set the target to reduce this slit from 1.8mm to 1mm to reduce patient recovery time. What we are looking at here is a cross section of a lens insertion tool. The green shape is the highly flexible hydrophobic acrylic and silicone intraocular lens and the blue part is the inserter tip . As a result the flexible lens’ have to fold in the inserter tool and pass through the slit so FEA was used to analyse the strain on the lens and visualise the deformation as it passes through the applicator channel into the eye The FEA model was compared and calibrated against physical test data to ensure the peak strain measurements correlated to previously experienced real-world failures points. This simulation approach has resulted in higher assurance of what will work when production is committed and failure modes mitigated in use.
The traditional engineering development process places the analysis after the development to validate the design pre-compliance
Integrating analysis and simulation into the design cycles moving it forward in the process means designs can quickly evolve and improve. This is effectively making the shift from using simulation as a validation tool to a research tool which can be used to derive insights early in the process that can be translated into innovation.
This is an example where we used FEA to explore and research in a biomedical context. Since early 2011 we have been working with a start-up company in Tauranga to develop and take to market a range of hip protectors aimed at preventing hip fracture in the elderly. Hip fracture is a growing and pressing global issue with projections of hip fracture incidence to exceed 6 million annually by 2050
Describe the product
Designed and built a rig to the IHPRG standard but achieved different results when tested on another rig with a different configuration soft tissue model Background to project - Completed a research project at the start of this year with an intern from the bioengineering faculty of Auckland University to explore the use of FEA in the development of biomechanical test apparatus for hip protectors. Use the tool to model and analyse biological components which means replicating these materials in the software package - this is complex because these materials aren't linear isotropic materials like engineering polymers or metals, these are biology materials which have complex non-linear behaviours
Literature research to identify the mechanical characteristics of the bio components. Important point for the process that requires a range of research skills for the best results. Required digging deep into biological research to identify the parameters. Biological materials are complex and highly non-linear which is difficult to model. They are filled with water which is affected hydration levels and the collagen fibres create an anistropic property where the mechanical characteristics differ in different directions which means they require more complex computation. This demonstrates the need to currently run physical testing to best gather this information - stress/strain sample testing or indentation testing of biological tissues.
A long way to go with this model to calibrate it to a realworld response but plenty of insight was derived from the preliminary model A view into the leg making what was previously invisible, visible Which soft tissue areas are best to shunt the fall energy Stresses in the proximal femur Stresses in the femoral neck
Then we moved to translate the material knowledge into a more representative physical model Matching to artificial materials - silicone is the closest match because of the non-linear, viscoelastic properties 2 grades identified - one to represent skin and muscle, a softer grade for fat
Further physical impact testing to clarify the position
Once the model has been developed and calibrated we can then iterate our parametric CAD models, adjusting materials and geometries, import into the model and validate before committed to material expense Thermal analysis can be run to evaluate comfort related factors Pressure analysis for understanding pressure sores Possible that soft tissue can't be accurately represented in artificial materials due to material limitations so the most accurate simulation is computationally.
Lean manufacturing is well established in New Zealand. It is a philosophy which was originally develped withing Toyota after the war. Tai-ichi Ono is considered the father of the 'Toyota Production System' which has become internationalised as Lean Manufacturing and in relative terms has spawned all the other elements of this. Tai Ichi Ono - Toyota Production System - Beyond Large Scale Production. Brilliant in its symmetry and how it has come about. Essential if you want to really get it from the horses mouth.
The japanese have a poetic way of considering even the driest of topics. I have always loved their ceramics packaging and many other things. I consider Hideuki Oka's How to Wrap Five Eggs as master piece. Like the Haiku.
Learning first is a structured method of product development which places a value on the development of knowledge.
