Moreover, the iteration concentrates on a particular assemblage of specifications. Every cycle finishes with a system that is used, for instance, a specific iteration outcome in an implementable release. The iterative Model enables obtaining previous stages, in which the alterations are made respectively. The ultimate outcome of the product is restored at the finish of the SDLC, the life cycle of software development. Usually, development in the iterative model is utilized in connection with accumulative development, in which an extended cycle of the software development is divided into shorter sections that are created upon one another. In brief, development in the iterative model is a manner of shattering down the software development of a huge application into shorter sections.

Specifically, Design Thinking is used at the beginning of development, and Lean Startup and Agile are combined for the definition and development of the different concepts. Lean Startup is a form of Lean defined for new product development by Eric Riese in 2012 in his book The Lean Startup [51]. This methodology emerged to create successful companies using continuous improvement. According to Riese, the success of start-ups lies in designing the right processes.

Agile Resources

The more adaptive your processes are to change, the better the output of your product. Remember that implementation and testing are sometimes repeated concurrently to guarantee no defects re-occurs. During this phase, you will construct your first iteration module’s technical architecture, database, and programmes.

It focuses mainly on people, interaction, community, skills, talent, and communication. Episodes are small developments that are the basis for different components. Once the different iterations are finished, the project is integrated, verified, and delivered [49]. In 2001, several agile design experts created the Agile Alliance, a non-profit organisation to promote agile development and support organisations that wanted to implement these methodologies [38]. Although Agile was created for software development, the philosophy promoted by this manifesto can be extended to any other product.

What is agile, iterative development, or the PDCA cycle?

Design Thinking is a human-centred approach to product design, innovation and problem solving. The first reference to the Design Thinking methodology dates back to 1969. Herbert Alexander Simon, Nobel Prize winner, mentioned this concept in his book The Sciences of the Artificial [54]. It was not until 2008 that Tim Brown defined the methodology as it is known today. This approach was published in an article entitled “Design Thinking” in the Harvard Business Review [55].

For example, SpaceX invested in an end-to-end 3D modeling system to view and manage their simulations. The system also enables them to 3D-print models to study what they would look like and how they would work in real-life. Today, you can find Casper mattresses in retail stores, and this decision has significantly contributed to the company’s growth. Had it not established feedback loops with its customers, Casper’s sales would have continued to plummet and its technology would not have continued to improve.

These boundaries keep the project on track and help developers focus on product design and quality. Iterative development contrasts with the traditional waterfall model of development in which each phase of the SDLC is carried out in a step-by-step manner. With the waterfall method, coding doesn’t begin until the design of the entire software application design is complete and has gone through a phase gate review. Likewise, testing doesn’t begin until coding is complete and has passed necessary reviews.

  • Gather feedback from your team members regularly, embrace the changing landscape, and celebrate every little win.
  • Each stage involves completing an increment of the overall software development cycle and adding it to the final product.
  • Incremental development involves breaking down the development process into smaller, manageable portions known as increments.
  • It includes items such as new features to be implemented and areas of redesign of the existing solution.
  • Each cycle is intended to bring the solution closer to completion and is always a collaborative process.

Therefore, this methodology seeks to minimise the investment made during the phases of maximum uncertainty. This methodology is defined in different stages so that by partially executing it, it can also be applied in those developments where both the requirements and the technical solution are clear. It covers the regulatory requirements for these types of devices and can therefore be applied to any embedded medical device development team. Agile methodologies, particularly Scrum, constitute a useful tool for start-ups as this methodology offers tools that quickly answer customer needs. On the other hand, Scrum requires experienced managers to apply the method to be effective. In addition, this methodology is not easy to integrate with the classical project management approach usually employed in medical device development.

Lean Startup is a product design methodology that focuses on customer needs. This method was born as an evolution of the Lean Manufacturing methodology. The origins of Lean go back to 1890, when Sakichi Toyoda, a textile entrepreneur, created several patents for machines that helped automate the work of operators. Kiichiro iterative development definition Toyoda developed this philosophy by focusing on the collaborative work of machines and humans to add value to production without generating waste. The SDLC (Software Development Life Cycle) is notably huge and abundant in numerous testing and development actions, techniques, methodologies, tools, and others.

However, it avoids traditional and rigid medical product development methodologies that do not allow for changes and customer feedback in the early stages. Finally, the third stage, Medical Product Consolidation, proposes the consolidation of the development through a V-model that meets all the regulatory requirements for the design and development of embedded medical devices. This methodology is particularly interesting for start-ups due to the type of solution they usually have, innovative ideas but with high technical and economic uncertainties. Its use is recommended in cases where the requirements are expected to remain stable throughout development [16].
