Sketching is the generative part of prototyping, the idea is to get your ideas out of your head in a more tangible.
Give reviewers the ability to reach agreements how to improve the work and reach the conclusion for fast imprvement.
Every designer has to answer to someone. Freelancers turn their work in to a client, company guys hand theirs over to a team or supervisor, there’s always someone next in the chain of command that gets to take a look and offer an opinion. It’s at this point that the initial draft ends and the creative review begins.
Sketching out the revisions ensures that every stake holder walks away from from collaborative design meetings on the same page. Written notes leave too much room for misinterpretation.
By sketching your revisions, the risk of misinterpretation is reduced. And since sketching is collaborative the client can easily contribute to it.
It’s in indirect opposition to”designing ib a vacuum” or “design in an ivory tower”. It’s design with and for people.
A presentation prototype provides a visual representation of a manufactured product and a demonstration of its functionality. It typically consists of a mixture of off-the-shelf components and production-grade material to achieve a balance between design, quality, and cost efficiency. A presentation prototype is typically used to demonstrate the product’s viability before it enters mass production.
A visual prototype is designed to illustrate the product’s overall shape and dimensions. It doesn’t typically contain moving parts, and the materials in this prototype usually aren’t those that will be used to make the final product. A visual prototype may be painted to more realistically portray the final product, but it may also be presented as the raw material.
A proof-of-concept prototype demonstrates the product’s core functionality in the technical aspects of its design. It may not physically resemble the final product, since this prototype is often constructed of off-the-shelf components. Proof-of-concept prototypes rarely use production grade materials in the interest of cost savings.
