Explore, create, evaluate

Plan it, make it, then test it

Research, build and finally sell

Sketch, mould, then finish off

A written exam paper and a spoken presentation

A chronological portfolio and one final prototype

Two finished prototypes and a display poster

A measurable specification document and nothing else

The final working prototype, ready to hand in

A full production plan with stages and tools

A design brief and a measurable specification

The final evaluation of the finished product

Primary research is always done last in a project, while the secondary research is always done first of all

They are really the same thing and the two words mean exactly the same in design work

Secondary research is always far more reliable than primary research, whatever the project is

Primary is gathered first-hand for this project; secondary already exists and was gathered by others

To find and fix faults cheaply and early, before committing time and materials

Simply to use up any spare materials that are lying around the workshop

Because the rough models are actually counted as the final product itself

To avoid having to write a measurable specification at the start of the project

Only the final selling price of the finished product, with nothing else at all included in there

The stages in order, tools and materials, dimensions and tolerances, quality checks and safety

Only a long list of early design ideas, sketched out before any making begins

Only the user's feedback collected after the prototype has already been made

Only right at the very end, once the prototype is fully finished

Only right at the very start, before any designing has begun

Throughout the project, with a final evaluation at the end

It does not happen at all because it is never assessed

Just by looking carefully at it and deciding whether it seems alright to you

By comparing it only to a rival product's advertisement in a magazine

By measuring nothing about it except for its total weight in grams

Against each measurable specification point and with the intended user

It shows critical judgement and identifies real improvements that feed the next iteration

It is not valuable at all; you should simply go ahead and claim that everything worked perfectly

It saves a useful amount of time when you are writing up the final portfolio

It removes the need to carry out any testing of the prototype at all

A single neat and tidy final idea presented with no changes ever made to it along the way

Testing that leads to documented changes and improved versions, with more than one loop

A long and detailed list of all the materials that were used in the project

Only the final evaluation written up at the very end of the whole project

How cheap the prototype turned out to be to make, from the very start right through to the finished item

How heavy the finished prototype is when you weigh it on the scales

How well the prototype meets the need it was designed for, judged against the specification and user

How quickly the whole prototype was made from start through to finish
