Developments and articles of interest from the last week.

• This article notes that the US Government is establishing a platform for its agencies to run innovation challenges and competitions. The site, Challenge.gov, will be launched in the next few months. As the article mentions, the Case Foundation and the White House, held a forum on challenges recently and have produced a short overview of prizes, challenges and open grantmaking with some advice as to when they are best used.
• The Australian Social Innovation Exchange (ASIX), the Center for Social Impact (CSI), and the Australian Centre for Social Innovation (TACSI) recently hosted a Social Innovator Dialogue with Ezio Manzini on designing innovation.
• Michael Schrage writes of the importance of simplicity in good innovation and how Tesco’s insists that innovations make things not only better but simpler.
• In this post Roberto Verganti writes about how to sell an idea to your boss, and the advantages of involving senior executives in the framing of the challenge the innovation is needed for, rather than coming to them with the solution.
• James Todhunter writes about why pervasive innovation is necessary in organisations and why they need to make the effort to establish a productive and sustainable innovation culture.
