What is Prototyping Software?

Software design takes time. Between design development and code simulation, there are many phases involved in the design process that culminate into a finished product. One of the first steps is prototyping, or making incomplete versions of a product to see whether or not it’s viable before coding anything. This process is used to present an idea of a design without the effort involved in building an entire code from scratch. Prototyping software also simulates the design to give developers an idea of whether or not specific parts work in a simulated and responsive environment. These simulations can be horizontal or vertical. Horizontal prototyping helps users see a design through a basic, interactive interface that gives them a broad idea of the visual and interactive aspects of the design idea. Horizontal prototyping doesn’t get into the nitty-gritty details of the code itself, just the superficial basics. This is ideal for users that want to present their design idea without dedicating much effort into the process. Vertical prototyping helps users visualize the deeper details of a design or the later stages of a design idea. This type of prototyping is more robust and is typically used by developers that are trying to understand specific facets of features and subsystems within the design.

Prototyping software gives developers a chance to test various versions of the software to ensure it’s functional and visually represents what the project requires. This platform allows users to collaborate on the development and discuss the prototype during various stages of the development process. The main benefit of this tool is to test a design in an internal collaborative environment against all possible scenarios that could stress or break the design. Users can switch between a design environment and prototyping environment for efficient workflow.

Key Benefits of Prototyping Software

  • Simulates software designs in horizontal and vertical environments
  • Lets developers collaborate and edit the code within the platform
  • Gives developers simulation test results that help improve the design

Why Use Prototyping Software?

Prototyping software is beneficial for software designers because it helps them build better designs in a collaborative environment. Prototyping software is ideal for users looking for direct feedback on their design in real time to help mitigate design flaws at various stages of development due to its collaborative features. Feedback can range from simple comments to direct edits by another user.

Prototyping software is also beneficial for companies that require approval before starting a design project. For example, a product design team may present a design to a development team using prototyping software since it does not require coding or development knowledge. This tool lets users present the idea in a visual manner without spending time completing the entire project. It’s also useful for software design teams that need to troubleshoot specific issues of a complicated design and require a visual representation of the issue at hand.

Who Uses Prototyping Software?

Prototyping software is mainly used by software designers, but can also be used by other types of developers including web designers. In addition, prototyping tools are used by professionals that have no software design experience, as they often don’t require any coding to use.

Software designers — Software designers mainly benefit from prototyping software as its a simulated environment for early software design projects. Teams can use this tool to analyze design ideas and pitch ideas to management.

Web designers — Due to its visual nature, prototyping software benefits web designers. Web designers can use this tool to visualize specific aspects of a web page and identify issues within the design based on simulated interactions with the web page in the testing environment.

Product designers — Since prototyping tools typically don’t require the user to code anything, this tool can be used by product designers that don’t have development experience. Product designers can use this tool as a way to brainstorm and preset product design ideas, which can be passed to developers.

Prototyping Software Features

Prototyping software typically includes the following features:

Prototype workflow — With prototype workflow, users can easily switch between design mode and prototyping mode within the platform. This lets users identify issues in the design in prototyping mode and quickly switch to design mode to fix it.

Wireframes — Wireframes are a blueprint, or a template, for specific sets of designs used within a designated prototype. Users can add included wireframes into a design within prototyping software. Wireframing software can be implemented to create these wireframes, also known as design models or blueprints, for specific aspects of a design.

Automated interactions — Users can add custom micro and macro interactions in design mode and test it in the prototyping mode. This feature ensures that each interaction works as it should in the simulated environment. For example, a prototype for a web page may require interactions for buttons leading to other web pages. This feature simulates the act of pressing the digital button.

Mobile preview — Since mobile devices are smaller, designs need to be optimized for changes in size. The mobile preview feature lets users view a prototype in a mobile device environment to see if it’s compatible.

Collaboration — Users can collaborate on projects by adding comments and feedback. When more than one person is working on a prototype, real time comments and feedback ensure errors and adjustments are communicated and resolved quickly by other team members.

Coediting — Coediting allows multiple users to edit a design at the same time. This is particularly beneficial for teams that are working on the same prototype at once. This feature also encourages remote team members to collaborate on the design without the need for physical presence.

Prototype sharing — Prototype sharing lets users share designs directly from the platform and control viewer access. This feature ensures that only a specific set of authorized users can see a prototype, which is especially helpful for prototypes that are confidential. Sharing directly from the platform is also more efficient for users since it involves less steps than downloading the file and exporting it elsewhere for sharing purposes.

MP4 download — MP4 downloading is a feature that provides users with a video download of the design that can be easily shared and presented. Video downloads are beneficial for users that plan on presenting their design externally. Video downloads can be shared or embedded on websites.

Asset management — This feature lets users store and manage designs in a cloud-based environment. Storing designs in a cloud-based environment ensures the designs are automatically backed up and lets users organize their library of designs as they see fit.

Potential Issues with Prototyping Software

Incomplete analysis — Prototyping software lets users hone in on specific, unfinished aspects of a design. Despite the time-saving advantages of analyzing an incomplete design, this can lead to issues once the design evolves outside the prototyping tool and is actually completed. Since a good amount of time is dedicated to testing the design of a product in a prototyping environment, developers may not feel the need to test the design as vigorously as they did in the prototyping software. Design testing should be an integral part throughout the development process.

Increased development time — While prototyping is a great way to granularly plan out a design, it adds time to the development process. Many design teams forgo prototyping due to time constraints. In some cases, a team’s design may be approved without a prototype. However, prototyping software is an essential part of building a product, especially enterprise products. The time and effort it takes to prototype a product pays off when the design reaches the end stages of development. For example, prototyping helps prevent unforeseen issues and bugs. It also helps convey the idea in a visual manner, preventing misconstrued end-result expectations.
