Design Iterations

Design iteration is a methodology which has an endless cycle around the process of prototyping, testing, analysing and refining a product or design. This methodology is ultimately determined to improve the quality and functionality of any design however with iterative design, the interaction with a design is formed from research allowing the best results to be published within a product/design in which adapts a concept from reaching its highest potential within projects.

This process is intended to improve and refine designs back and forth to find any tweaks that needs to be handled before any final project is released.

Below is a diagram showing the iterative design process showing each point in which gathers information and research to move onto the next step that leads towards the final design and publishing.

When problem solving another method is used within the world of design especially in software development which is called the’ Waterfall model’ as the process requires a step by step guide from a simplistic approach by flowing steadily downwards just like a waterfall. Within this methodology it is easier to structure as it can be applied to the current time frame through each stage of development.

Here I have a clear example of how the Waterfall Model methodology works:

The limitation of the Waterfall Model is that it does not give the designers themselves to experiment or enhance any further solutions once the task has been solved as there is no re-evaluation or refinement unlike the Design Iteration methodology which gives the designers more free will to build there skills in both technical and visual knowledge.

In the world of design, designers prefer to use the iterative method as there is a repeat of looking back and forth within the concept through the use of experimentation, prototyping/testing and evaluating. Just like I said before they go through a endless cycle until they believe they have a finished product before the client themselves evaluate the product, this way the designer has solved more problems as well as having a few extra back up ideas which could meet the requirements of the client and satisfy both parties by enabling more skills within the designers side and a better product for the client.

An example of iterative design could be used within the company of Apple.Inc, with there product of the iPod. For instance the iPod Nano evolved into a slim Mp3 player which displayed on a small screen and adapted to a tiny square touch-screen additionally to a longer and thinner touch screen version. From the simple idea of just playing music of Mp3 files to adding apps that allow the user to be flexible with there own preferences and custom settings, this was achieved by using the iterative design process making sure each step was re-evaluated and refined to different customers. This from a designers point of view shows different aspects of iteration through the same product as the goal from designer to audience is to find the perfect combination of features that satisfy both the needs of the customers and designers ability to problem solving.(YourDictionary, 2014)
