FROM SKETCHING TO PROTOTYPING

Cons of low-tech prototyping

Cannot be used to get feedback about aesthetics or usability issues Users might question design quality Requires lots of hand-holding

10 plus 10 method

1. State your design challenge 2. Generate 10+ different design concepts that addresses that challenge 3. Reduce the number of design concepts OR repeat OR Based on reflection, repeat step 2 4. Choose the most promising concept(s) 5. Produce 10 details / variations of that concept 6. Present your ideas to a group 7. As your ideas change, sketch them out

Pros of high-tech prototyping

Better sense of finished product More realistic experience Can evaluate experience

Pros of low-tech prototyping

Fast and Cheap Does not require technical skills to produce Stakeholders might be encouraged to iterate on its design Users might be encouraged to provide feedback Useful for quick feedback

Fundamental prototyping principle

Prototyping is an activity with the purpose of creating a manifestation that in its simplest form filters the qualities in which designers are interested without distorting the understanding of the whole.

prototyping techniques

STORYBOARD - Sketches or screen shots illustrating key points in a usage Narrative PAPER OR CARDBOARD "MOCK-UP" - Fabricated devices with simulated controls or display elements (seen in C07) WIZARD OF OZ - Invisible human assistant who simulates input, output, or processing functionality not yet available VIDEO PROTOTYPE - Video recording of persons enacting one or more envisioned tasks WORKING PARTIAL SYSTEM - Executable version of a system with a subset of intended functionality

Best practice of sketching

Sketch alternatives (getting the right design) Sketch details (getting the design right) Annotate drawings Don't erase ideas Don't use it for other things for design only

Sketches vs. Prototypes

Sketches are about exploring ideas Prototypes are about testing ideas

Use of sketching

Sketching is a tool to help you: Express develop, and communicate design ideas Sketching is part of a process: idea generation, design elaboration design choices, engineering

Preprotyping

Testing the initial appeal and actual usage of a potential new product by simulating its core experience with the smallest possible investment of time and money. The word came from "pretending" and "prototyping"

Pretotypique techniques

The Mechanical Turk - Replace complex and expensive computers or machines with human beings The Pinocchio - Build a non-functional, "lifeless", version of the product The Minimum Viable Product (or Stripped Tease) - Create a functional version of it, but stripped down to its most basic functionality The Provincial - Before launching world-wide, run a test on a very small sample The Fake Door - Create a fake "entry" for a product that doesn't yet exist The Pretend-to-Own - Before investing in buying whatever you need for your it, rent or borrow it first The Impersonator - Put a different label on an existing product that looks like the product you want to create.

Economic principle of prototyping

The best prototype is one that in the simplest and most efficient way makes the possibilities and limitations of a design idea visible and measurable. This principle should guide the nature of the manifestation in a prototype

Cons of high-tech prototyping

Users and stakeholders might focus on unnecessary details Costly to make Requires technical skills

Why service blueprint

When thinking about the UX of an interactive design, you need also to think about the big picture. It helps you take a step back and contextualize the UI of your product and service in the larger context of the user actions and business operations.

Service blueprint

is a model that clarifies interaction between customer interactions, employee roles, operational processes, and information technology

Prototype

represents enough of the appearance and function of the product that it can be used for user research
