• prototypes - the fundamental

  activity in structured innovation,

  collaboration, and creativity in

  design
• Its primary purpose is to involve

  the users in testing design ideas

  and get their feedback in the early

  stage of development, which will

  reduce the time, cost, and effort.- prototypes
• The goal in prototyping is not

  the prototype itself, but it's

  feedback.
• • Benefit of prototyping,Much cheaper to change the system,Collect the feedback coming from the user, define you idea polish and shape it , Explanatory but less risky than presenting final product without planning, Great tool that you can use to explain your ideas to your client.Can act as you vision and identify any loopholes or need for improvement of the system
• It's not the actual system or

  product. Don

  't treat it as a fully functional

  system or product.
• Refrain from adding too many

  complex features at this phase. - Do not make it too complicated.
• Do not over-spend- It is unnecessary to invest too much on

  the resources that incorporate highly

  advanced technology unless it is a must to

  represent your prototype.
• Don't let the schedule slip.-Refrain from confusing others and

  getting yourself confused. Use a

  tracker to avoid confusion and

  keep everyone on the same page.
• Don't lose sight of your idea - Don

  't create a replica of an existing

  system or product in the market. Focus

  on your plan, study about it thoroughly,

  and build your vision to reality.
• Target users


  The users of your proposed system or product
• Define the product's vision

  1. Determine the long-term and short-term goals

  2. Identify the main features

  3. Identify the requirements to define the system's goal
• Create a clear set of requirements

  1. Make a list of minimal and most essential features

  2. Prioritize the requirements

  3. Remove what can be avoided at this phase
• Divide the project into small tasks


  1. Group the similar ones

  2. Prioritize them first

  3. Prioritization of tasks will help set timelines to stay on track
• Use smart hacks to save time and effort

  1. Develop

  2. Test

  3. Lock out one section first

  4. Use it as a base for other similar sections
• Set timelines for all the individual tasks of the entire project


  1. Achieve a clearer vision of your achievements

  2. Identify what is pending from the tasks
• Document the entire process


  1. Document blockers

  2. Document loopholes

  3. Document any other important stuff encountered while working on the prototypes

  4. It will come handy when the existing system or product building phase starts
• Prototype


  • Keep it simple
  • Avoid adding too many complicated features
  • Avoid adding advanced technology at this stage
  • Appreciate the beauty of a prototype in its simplistic and minimalistic features
• Low Fidelity

  Prototype

  Low Fidelity Prototypes

  enable early visualization of

  alternative design solutions to

  innovate and improve the

  product or system.
• High Fidelity

  Prototypes

  high fidelity prototypes take

  you close as possible with a

  real-time representation of

  the user interface
• Verbal prototypes

  ideas can be depicted by

  discussing something

  thru speaking or

  communicating.

  focuses on discussing

  your project or system

  by seeking feedback,

  asking questions, sharing

  details, and pitching your

  idea
• Paper prototypes

  a technique that consists of

  creating hand drawings of

  user interfaces to be rapidly

  designed, simulated, and

  tested.

  can provide useful

  feedback to aid the design

  of more accessible to use

  the products.
• 2 Significant Uses of

  To communicate ideas: between

  designers, developers, users, and other

  stakeholders in the first stages of the user-

  centered design process.

  use as a usability testing technique:

  observe human interaction with user

  interfaces even before these interfaces

  are designed and developed.
• • Advantages of paper prototyping
  • Involvement of user in early phase
  • Does Not require coding and designing skill
  • Cost effective
  • Less resource consuming
  • Rapid evaluation testing
• • Disadvantages of paper prototyping
  • Lack of realism 
  • Lack of user control
  • Inappropriateness in some context 
  • Must interpret result carefully
• Interactive prototypes

  it is considered a visual

  language that enables

  designers to represent their

  idea in a series of

  interactions.

  It is a process of exploring

  design ideas by building an

  interactive experience that

  helps the users understand

  your vision better.
• Working prototypes

  represents an early example

  or model of a product or

  system, built to test a

  concept or process to be

  learned from or to show with

  clients to understand its

  features better.

  implemented using 3D

  printing, usually the best to

  build and develop real-life

  functioning product
