School of Business ISY00243: Prototype Presentation Analysis

This presentation, prepared for the ISY00243 Systems Analysis and Design course, focuses on the significance of prototypes in product development. It begins by defining a prototype as a preliminary version of a product, crucial for outlining design and concept to users before full-scale development. The presentation then distinguishes between low-fidelity prototypes, often paper-based and lacking user interaction, and high-fidelity prototypes, which offer a realistic user experience. It highlights the benefits of prototyping, such as improving the quality of requirements and specifications by gathering customer feedback to refine designs, reduce costs, and incorporate user-suggested features. The presentation also acknowledges potential drawbacks, including the risk of developers misinterpreting user objectives and the possibility of users perceiving prototypes as final products, potentially leading to product failure. Finally, the presentation includes visual examples of smartphone interface designs to illustrate the evolution of a product from low-fidelity prototypes through to the final design.

Slide 2:
Prototype is a draft version of the finished product which outlines the overall design and
concept of the product to the users before being developed. The prototypes allow to explore the design
of the product before the actual product is produced or manufactured.
Slide 3
The first one is the Low-fidelity prototype that is mainly prepared by paper and it has no chances
of user interaction. E.g: this prototype is mainly hand drawn mockups to printouts. On the other hand
high fidelity prototype allows the realistic experience to the user and it is almost as same as the actual
product. High fidelity prototypes can collect the user experience data (Homburg, Schwemmle and
Kuehnl 2015).
Slide 4:
Prototype can improve the quality of the requirements and specifications that is provided to the
customers. After taking feedback from the customers, the company can modify the design, lower the
cost and can add more features to the product that is suggested by those customers (Odom et al. 2015).
Slide 5:
The focus on limited prototype design can misguide the developers from properly analyzing the
actual product. In some cases, users think the prototype as the final product and reject the product. In
some cases the misunderstanding of the user’s objectives by the developer can cause a severe failure of
the product (Odom et al. 2015).
Slide 6:
The image shows four designs of a smart phone interface. The first two designs are low fidelity
prototypes, the third one is a high fidelity prototype while the final design is of the actual product. These
images show the evolution of the design of the smart from the first prototype to the design of the
finished product as a step by step process.
