Rough vs Polished Prototype: What is Your Best Option?

You have an idea for a new or improved product and you want to get an idea of how it will be received by the public. You’re ready to create a prototype, get feedback and move forward with your project. But, should you go with a rough prototype or a more polished prototype? The answer to this question depends on your plans for your product.

What is the Purpose of Your Prototype?

Is your product a component of another piece? Is what it looks like as important as what it does? If you are trying to prove that your product functions as it should, then a rough prototype will be the best option. A rough prototype can be reworked and redesigned if there are mechanical or design flaws1. Aesthetics, on the other hand, may be as important as function if the product will be purchased based on looks as well as function. In this case, a polished prototype may be the way to go.

Who is Your Audience/Customer?

Are you talking to potential customers or end users? Or are you pitching your product to potential investors? Customers may be more interested in whether your product works as it should and less interested in what it will look like as a finished product, so a rough prototype is appropriate. For end users, knowing that you have a viable idea is more important than seeing a pretty object1. Potential investors may want both, seeing that a product works and what the final aesthetics will be. Investors want to know that their money is going to help create a workable product that will be popular with customers and end users, so a polished prototype would be the best option2. Customers want a product that works, and aesthetics can come later. Therefore, your audience will help determine whether to use a rough vs a polished prototype.

Who is Your Audience/Customer?

What Type of Feedback Are You Looking For?

Do you want to know if the product functions as you want it to? Are there design flaws or mechanical problems that need to be addressed before full production? If this type of feedback is what you’re looking for, a rough prototype is the place to start. With a rough prototype you can test function and design features before putting the product through full production. If there are issues with the rough prototype, you can start over and make changes to the design or function, saving time and money in future production delays and waste3.

Do you want to know if your product will be popular with the public? Does your product make potential customers say “Yeah, I want one of those!”? If this is the type of feedback you’re looking for, a polished prototype may be what you need. With a polished prototype you can find out if potential customers would want the product as is or whether the customer would prefer some changes be made. When a potential customer sees a functioning, aesthetically pleasing prototype, they will be more likely to provide feedback that lets you know if your product is desirable enough to purchase. Choosing a rough vs polished prototype is important in gaining the correct feedback for your product2.

When using a rough prototype, you will most likely get more open feedback. A rough prototype also allows you to determine if the product is working as expected or if you need to make structural or design changes. Each type of prototype will garner different feedback depending on your audience. A polished prototype may confuse your audience into thinking the prototype is the finished product. Be sure to emphasize the difference between the two types of prototype with your audience to ensure you get the correct type of feedback3. Prototypes are very advantageous for production of a well-functioning product that will satisfy both investors and end users. Determining rough vs polished prototype is an important decision, so know what outcome you are looking for when making that decision.

7 Benefits of Prototypes in Manufacturing

Do you have a business dream you want to bring to life? Or maybe you already have a business that you want to expand with new products. Do you think using prototypes to obtain funding or garner enthusiasm for your product may be a good idea, but aren’t sure if the costs outweigh the benefits? Here is a list of 7 benefits of prototypes and a possible way to bring down the costs of their production.

What is a prototype?

All types of industries use prototypes, but in manufacturing a prototype is typically an early model of a product used to develop aspects of the actual finished product. Prototypes provide proof a design is viable and an idea of the aesthetics of the design. Prototypes also provide information on production techniques, materials, and costs. Prototypes allow you to receive feedback from stakeholders, such as distributors, retailers and customers.

Categories of prototypes

There are several categories of prototypes that provide feedback during different stages of manufacturing. Each category has a different function and look. Prototypes can be made from different materials, on a different scale, and with a different appearance than the intended finished product. The benefit of each prototype also differs.

One category is the Proof of Concept prototype that tests design function of a product without full functionality6. This prototype determines if the materials and the product perform as they should. A benefit of this prototype is it allows you to make design changes before the manufacturing process starts, saving time and money.

A Visual prototype does what it sounds like. This prototype shows the size and appearance of the finished product, but not the functionality of the product5. A Visual prototype is used in marketing for ads and packaging. Part of this category is the Form Study prototype which emphasizes the design’s geometric features, but not other aspects such as color or texture6.

A Working prototype provides the functionality of the finished product, but not the final appearance of the design6. This prototype determines if the final product will function as it should. This prototype makes it possible for you to change the design to improve functionality.

A User Experience prototype has enough of the final product’s appearance and function to be used for end-user research6. This allows for consumer testing to determine if the product is user-friendly and satisfactory for the end-user. The benefit of this prototype is in allowing you to see how customers are going to interact with the product. Data from this type of prototype research provides the opportunity to make improvements for customer satisfaction.

A Functional prototype has the full appearance and functionality of the final product6. However, this prototype may be made with different materials and techniques than the final product. Possibly even on a different scale than the finished product to save on production costs. The Functional prototype is often employed to obtain funding for production.

What are the benefits of prototypes?

Prototypes provide many benefits to you. Everything from basic design to end-user satisfaction can be benefited by use of prototypes. Several of the benefits of prototypes include2:

  • Early discovery of design problems
  • Estimate production costs, manufacturing time, and requirements for materials
  • Determine machinery necessary for production
  • Testing to determine fit and durability
  • Receive feedback from client and end-users/identify improvements
  • Determine final function and design
  • Aid in obtaining funding and investors

The first benefit of prototypes is determining design problems and other manufacturing issues. Early detection can avoid issues further down the road during manufacturing, limiting costs of waste and reproduction of flawed parts.

Prototypes aid in estimating material requirements and costs. Prototypes also aid in determining manufacturing time and personnel requirements. These elements help you to acquire funding, create budgets, and determine the final cost of the product4.

Can the product be produced with existing machinery? Are adaptations necessary to manufacture the product? Is it necessary to purchase new machinery? Creating prototypes helps you to determine if any adaptations to current machinery, or new machinery, is needed for production.

When making assembly parts, creating a prototype makes it possible to determine if the fit of the parts is correct. This saves money in time lost to rework and the cost of wasted materials. Prototypes also help determine if the materials used are durable and capable of withstanding the wear and tear of use.

Another benefit of prototypes is the ability to receive feedback from clients, distributors, and customers. Feedback such as this helps determine the final function and design of the product4. Customer research and feedback helps to create customer satisfaction and provide you with confidence in the product’s marketability.

Are there disadvantages?

One of the main disadvantages mentioned by developers and manufacturers is the cost of creating prototypes. According to Tamara Monosoff in “Entrepreneur” magazine, prototypes in the United States can cost “from $10,000 to $100,000”3. However, a recent process called rapid prototyping, can save you thousands of dollars1. Rapid processing uses 3D printers to create prototypes quickly and for just a few hundred dollars compared to thousands.

A 3D printer can run between $200 to $2500 or more, depending on the size and purpose. Material for printing can be plastic or metal. The cost for printing plastic can be as low as $25 per kg to more than $48 per kg. Therefore, even purchasing on the high end could save you thousands of dollars in prototype creation. If you don’t want to purchase a 3D printer, there are companies that will do the work for you.

The benefits of prototypes are many and can be used in almost any business environment. With the variety of prototypes available you can find the one that will suit your needs. Whether you need to identify production issues, improve design elements and functionality, estimate costs, conduct research or obtain funding, there is a prototype to help. New technologies, like 3D printing, help to bring down costs and make prototyping available to almost any business or budget. Overall, now would be the time to take advantage of the benefits of prototyping and technological advances for your business.

Difference Between Evolutionary Prototyping and Throw-away Prototyping

The prototype converts industrial ideas to concrete realities. A highly trained professional team will adopt your entrepreneur idea specifications and sketch your ideas using the latest CAD technology. Next, with the help of computer simulation, these CAD drawings are transformed into a prototype which is an exact copy of the final product.

Prototyping helps you get an accurate and complete working model of innovation, adjust the weight of several different options, adjust them, and ultimately create the perfect design.

Evolutionary Prototyping

In evolutionary prototyping, the concept of the system will be developed as the project progresses. First of all, we will develop the most visual aspect of the system. You present a portion of the system to the customer and continue to develop prototypes based on the feedback received. At some point, you and the customer agree that the prototype is “good enough” and release the prototype as the final product.

It is may be best suited for business systems where developers can interact frequently and informally with end users. However, it is suitable for commercial, shrink wrap, and system projects as long as end-user involvement is obtained. Communication with users of these projects is generally more structured and formal.

If evolved prototyping does not provide more control than is necessary or if you already know what the system should do, you can use evolutionary delivery or gradual delivery instead.

Evolutionary Prototyping Model

Advantages of Evolutionary Prototyping

  • It’s useful for exploratory programming, such as Artificial Intelligence applications, where it is difficult to frame specifications.
  • If big problems are anticipated, developers can stop development after several iterations.
  • This model is very suitable for research projects. For example, in order to develop software for automatic speech recognition, it is possible to take a small vocabulary and develop a system. After successful, you can gradually increase your vocabulary. This approach is superior to starting the development of an unlimited vocabulary speech recognition system directly (I recognize it is very difficult in two years).

Disadvantages of Evolutionary Development Model

  • As the project is open-ended, no time frame is able to be set.
  • It is difficult to monitor the project.
  • The visibility is low compared to the waterfall model.

 

ThrowAway Prototyping

The throw-away prototype is cheap, fast ones, which is designed to model an idea or feature. They are commonly used in early phases of design when a large number of ideas are still being considered. throw-away prototypes may also be used in late stage design in industries in which products are launched at a low state of refinement.

The throw-away prototype sounds like what it is. You make a prototype, then when you are done with it, you abandon it. For example, you and your colleagues go to lunch, you come up with an idea of the new product. When you discuss the idea, write down the idea and pull out the original design of the paper napkin. When you return to the office, take out the prototype of the paper napkin and transfer it to your computer. You throw out the napkin. In that case, the napkin is considered a thrown away prototype.

The throw-away approach is most appropriate in the project acquisition stage, where prototypes demonstrate the feasibility of new concepts and convince potential sponsors to fund the proposed development projects. In this situation, available resources are limited and the ability to convey the benefits of a new approach with a very low-cost demonstration is essential to create a new project.

You can also skip or omit the throwaway code document. If this trial is not recorded, lessons learned from prototyping efforts may be lost, and without the documentation or deterioration of the initial design simplification, progress in prototypes is hampered and customer needs Regarding the scope of prototype effort. The throw-away approach can be a drawback for insufficient level of technology and is best suited for rough system mockups used very early in the project.

Advantages of Throw Away Prototyping

  • Save time and money
  • Promote consistency of user interface design
  • Enable early customer engagement
  • Show concrete ways to show and believe in management to management. Instead of telling the administrator
  • Marketers and planners guarantee that customer needs are met.

Disadvantages of Rapid Prototyping

  • User confusion for prototypes and completed systems
  • Excessive development time of the prototype
  • Normally it does not generate reusable code
  • The development process slows down when placed under formal configuration control
  • There is no clear stop point

How to Develop a Prototype for Your Website or Application

Developing a prototype, an example or model, is part of every software development today. But what are the advantages of a prototype, compared to the simple concept development? And how do you make the step from prototype to finished product?

The development of a prototype

A prototype can have different shapes and can be very little developed or very accurate. Wikipedia defines a prototype as follows:

A prototype is an early sample, model, or release of a product built to test a concept or process or act as a thing to be replicated or learned from. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming.

The advantage of a prototype is that it can be changed faster and changes cost less money and time. The development of a prototype should therefore be at the beginning of a product development.

Prototype Developments
Prototype Developments

A prototype can also be used to inform investors about a product or to gain initial user experience. A prototype should answer a concrete and not an abstract problem.

Prototype + User testing = Better products?

Developing prototypes can help you to develop a great product.

It’s a relatively inexpensive way to test an idea and get the first user feedback. If a prototype fails, this is far less serious than if a finished product failed, as the investment was far lower.

In addition, a prototype has the ability to completely rethink and redesign it, which is rather difficult for a finished product.

Prototypes are a great opportunity to collect and respond to user feedback. As bad as shown here, it should not be better 😉

High fidelity and low fidelity prototypes

When you look at prototypes in software development, you find the terms “high fidelity” and “low fidelity”, which can also be equated with “high tech” and “low tech”.

A low-fidelity prototype can e.g. B. the conception by means of paper and pen or post-its. Often, the low fidelity prototype is also the starting point for the high fidelity prototype.

Sketch Low-fi High-fi Website Mockups
Sketch Low-fi High-fidelity Website Mockups

By contrast, the high-fidelity prototype presents the future product at a high-tech level. Designs are created here and often the high-fidelity prototype is fully functional. However, this also means significantly higher costs and time, which flow into a high-fidelity prototype. Of course, one can understand low and high fidelity prototypes as two instances, but rather as two ends of a spectrum in which there are many intermediate possibilities.

What should your prototype look like?

Before you start to develop a prototype, you should answer the following questions:

  • How far should my prototype be developed?
  • How much budget and resources do I want to spend on developing the prototype?
  • Who is involved in the development?
  • What will the workflow and internal communication look like?
  • How do I get first user feedback?
  • Which tools are available to me

The right tools

Especially if you are developing a high fidelity prototype, you need the right tools for your project.

Depending on whether you are developing a mobile app or a browser application, the tools you need can vary greatly. Also, depending on where you are in development, you need different tools.

I can therefore recommend this article, which gives you a good overview of tools such as Briefs, Atomic.io or Axure. Here you can see how different tools perform in terms of speed, high fidelity, user testing and customer support.

User feedback

User testing used to be the last step in software development. As a result, user feedback could only be incorporated at the very end and sometimes costly changes. Fortunately, that has since changed and user feedback is now part of every design process.

When developing an application, it may make sense to ask users for a prototype for feedback. Everything you learn in this step will save you a lot of effort afterward.

Conclusion

The advantages of a prototype are obvious: you can show an example or model very quickly, you save costs, resources and time. It is therefore worthwhile to plan the development of the prototype exactly, from the tools to the team to communication channels.
