Much of current design practice has been influenced and guided by design methods. For example, the influential IDEO consultancy uses design methods extensively in its 'Design Kit' and 'Method Cards'.[40][41] Increasingly, the intersections of design methods with business and government through the application of design thinking have been championed by numerous consultancies within the design profession. Wide influence has also come through Christopher Alexander's pattern language method,[42] originally developed for architectural and urban design, which has been adopted in software design, interaction design, pedagogical design and other domains.
