Step 1 – has it been done? Step 2 – can it be done? Step 3 – can I do it? Step 4 – what do people want? Step 5 – getting it on paperStep 6 – show me the money ! Step 7 – is my idea worth protecting ? Step 8 – who will make my prototype ? Step 9 – do I sell direct ? Step 10 – testing timesStep 11 – the final product ?Step 12 – Show me the money ! ( Investors )Step 13 – Marketing Strategy ?Step 14 – Organization setup

Prototyping or Trial ProductionDesign Review

Manufacturing Setup including test SetupDocumentation

Agency Compliance

Follow up Sizing up the task

Idea for a new product, A variation on an existing product, The identification of a need for an undefined product

Concept

Research is to drive realisation of Concept by Identifying Technology Finding Methods People/Company Producing

Research

Creation of Schematic Diagram BOM generation Prototyping the functional blocks Final Integration

Circuit Design

Selection of Suitable shape and size, Mechanical drawing to be designed using CAD/CAM

Material for Housing based on application requirement.

PCB is finalised accordingly. This is final PCB which is easy to assemble.

Packaging & Printed Circuit Design

3D plotting / Hand made prototyping Post mould production for design and function finalisation

Prototyping or Trial Production

Evaluation of Prototype for Function Appearance Built- cost reduction / optimisation possible enhancements to exceed the original goals even marginally

Design Review

Production line for manufacturing Testing on Line, Calibration and Final Testing of finished product. Long term testing of each lot of produce.

Manufacturing Setup including test Setup

Concept HLDD ( High Level Design Documentation) Circuit diagrams with functional explanation Schematics and PCB designs Parts List / BOM with pricing Sources of procurement Mechanical Drawings of the Enclosure Mould usage documentation Assembly line documentation Assembly process and Time Lines Product Packaging ( Cushions etc.. )

Goal is to Document complete Life cycle and Production process for enabling any EMS provider to manufacture the product.

Documentation

Agency compliance may be required by law. For product liability insurance coverage. Agency compliance can cost several thousand dollars per agency Can add months of time to accomplish. It is not to be taken lightly or left as an afterthought.

Agency Compliance

The manufacturing facility experience, The product support data, The user responses,

Follow up

Review for the purpose of steering future designs and marketing.Don't forget this crucial step on the road to improved quality, value, and often lower cost.

If you can buy something, do not build it or anything similar without some truly overwhelming justification.

Always make a mock up or model, even if it is cardboard with hand drawn features. It will pay for itself again and again, and you will learn something crucial each time you build one.

Sizing up the taskThere is Good, Cheap, and Fast.

You can only have two of the three at any one time.
