More models of the design process:

One of several models from book on advanced technology design.

Formal process from Australian Standard for Product Design based on British standard:

Extended model from Standard for Product Design

Model from statistical process control, and quality assurance.

Note the inclusion of design for manufacture, for building and construction projects could replace this task with design for construction. Alternatively consider design for production, which comprises of design for manufacture and design for construction. Where manufacture concerns fabrication  which can be done off-site or on-site, and where construction concerns that activity which can only be done on-site. (eg. construction tends to include earthworks, and pouring of concrete, and lifting items into place using cranes.)

Though an alternative meaning of construction can be considered to be assembly. Fabrication and manufacture, include assembly and the shaping of materials. The shaping of materials can be by material removal processes, or by molding, or by additive processes. I prefer to limit the term construction to large scale works on site. Thus aircraft and ships are assembled, whilst dams and bridges are constructed.

Another criteria concerns whether materials are brought to the tools, or tools brought to the materials. Construction typically involves bringing the tools to the materials, that is typically the construction site. In a workshop, workpieces typically move from tool to tool, or workstation to workstation.

Anycase the important point is that do not just design the end-product but also design the process to make the end-product. Cannot assume that people are available who will know how to make the end-product or have the necessary tools and resources.

Often builders tell us that something cannot be made. What they really mean is that they are not willing to make it the way specified, and that is because they do not have the necessary resources and such are not readily available to them. Or put another way they don’t want to subcontract the work to some specialist, and thus have no work themselves to do.

So design of an end-product is dependent on the available resources, which includes materials, tools and the skills of the people involved. Owner-builders typically are more willing to try new things, they typically choose to be owner-builders because they cannot find a builder willing to construct their project, or a willing builder with a price they find acceptable. Owner-builders may be willing to take longer and spend time learning to achieve their objective. More detailed drawings are beneficial to owner-builders, whilst builders are likely to ignore the drawings. Though builders choosing to ignore drawings and charge ahead with what they expect typically results in a failure to build to the intent of the drawings. The typical result of such action is loss of features in a building, or delays in putting things right.

The design of a new product thus involves the design and implementation of all the infrastructure required to bring the product into existence. Until such infrastructure is available the product cannot be made.

So setting up manufacturing in a place like Australia is not just a matter of having a product idea, it’s also a matter of having the necessary infrastructure to support manufacture. Part of the support infrastructure concerns the logistics of supply and distribution. Where are the raw materials coming from (supply), and where are the finished products going to (distribution)? Which is part of the reason I have been messing with the 5km diameter circular cells.

Basically the internet is important to creating connections between Australian business, so that all know the resources available in Australia and can thus make use of local resources: rather than finding  the more commonly known multinational players and using their services.

For example suppose have a small general purpose workshop on the Yorke Peninsula, is it possible to put enough work through that workshop to keep it going indefinitely, or can it only have a small intermittent workload, with the owners having to find other work during the lulls? Can the internet help remove those lulls?
