Usability Methods Explained: Design Patterns – Part 1

In this blog post I shall look at design patterns as a usability method in 2 parts. In part 1 I shall look at what design patterns are and the advantages of using them in interface design.

What is a design pattern?

Design patterns are a useful method for the interface design of websites and software programs. One of the hallmarks of humanity is the evolution of our empirical collective body of knowledge that succeeding generations have built upon to get us, a relatively feeble creature, to where we are today. Anyone wishing to start a fire to prepare a meal does not have to accidentally discover fire first! In the same vein design patterns are a collection of solutions to typical problems encountered during the interface design of web sites and software programs. Over time these interface design problems have been documented and paired with solutions to assist all interface designers be they a novice or a seasoned professional.

What are the advantages of design patterns in interface design?

One of the ways of ensuring good usability in interface design is to always adhere to usability standards. These standards have been tried, tested and proven to work. Design patterns are there to assist you in solving the common problems encountered during interface design, including usability issues, thus enabling you to optimize your time much like a shortcut takes you to your destination faster. Design patterns sum up best practices and can be thought of as a template or guide that interface designers can use as a direct solution or a starting point to fine tune their interface designs.  Design patterns are also useful because they function as a code or standard that can be used by software developers, interface designers and other stakeholders to communicate and collaborate more efficiently. Novices can become accustomed to them and rely on their proven success, while professionals can share and show their expertise. Design patterns are also continuously being updated, tested and improved upon by an ever growing community of information architects and interaction or interface designers.
