Published on

Presentation delivered by Craig Smith at Agile Australia 2011. Ensuring that the approach to testing and quality is understood and appropriately valued in an Agile world can be a struggle for many organisations, especially when resources are limited and our customers are expecting business value in a timely manner. In this session Craig Smith will define what quality means, share a number of tools for measuring it as well as discussing approaches to improving the skills, empowerment and role of testing in the organisation and share why testing is the coolest role on the team and why it is everyone's responsibility.
