Software Prototype – The First Step in Custom Software Development

Software Prototypes Importance in Software Development
Think of a software prototype as a scale building model that is used in architectural design projects. When it comes to large buildings, architects invariably build a scale model to give stakeholders a better understanding of what the end product will look like. A blueprint may not be enough.

While an architectural scale model is a sophisticated prototype, a software prototype might not always be this extensive but it serves the same purpose. A software prototype is needed to gather early feedback making it easier (and cheaper) to make necessary changes at the start rather than a few months down the line after the development team has fully coded the application

Why does prototyping matter for custom software development? 

A software prototype is worth 1000 meetings. That may be a bit of an exaggeration but it still conveys the importance of creating a software design wireframe before entering into coding.

A prototype is an essential first step in the development process of creating a web software or mobile app. Designers, developers, stakeholders, and even end users can review the user flow and design and address pain points in advance.

Prototyping is the third stage in design thinking and the first step from the development side. The different stages in design thinking are

  • Research users’ needs: Empathize 
  • What will your product solve: Define
  • Brainstorm ways to meet these needs: Ideate
  • Experiment through trial and error: Prototype
  • Show users a prototype for feedback: Test

Software design prototypes can be as simple as pen-on-paper mockups, wireframes using design tools or a simplified coded version of a functioning app.

SDLC Phases in Prototype Modelling

Types of Software Prototypes

There are 4 practical classifications for a software prototype and businesses need to know which one will work for their situation.

1. Rapid Prototyping: This is ideally suited for Agile development methodology where the project is divided into short sprints. In such an SDLC – software development lifecycle – prototypes are made of smaller functionality or additions. It is also called throwaway prototyping because prototypes from earlier sprints might no longer be relevant since there is an addition of new functions through various sprints.

For instance, when iTech builds a rapid prototyping model, we prepare data, build the first version of UI, and Integrate APIs if required for a basic end-to-end experience so that it can be presented to the stakeholders. It also must be said that not all projects need a prototype. If a client already has tech advisors and the requirements and specifications are clear, we go directly into development.

2. Feasibility Prototypes: This type of prototype is opted for when fundamental answers to the product are needed that research alone doesn’t provide. It usually is asked when developing an innovative product to know if greater investment is called for and if the idea is worth pursuing. It could also be called a minimally viable product or MVP. Feasibility prototyping will also provide the development team and stakeholders an insight into which part of the product might have technical difficulties in implementation.

One of the main benefits of feasibility prototypes is to spend a minimal amount of time in development at the fraction of the cost of a full product. It ensures that it significantly reduces future development risk.

3. Low-fidelity prototypes: The
