Third Stone caters process to project, according to technical demands, resource availability and project scope.

For mainstream application development projects Third Stone has adopted a primary subset of the Extreme Programming development methodology complemented with additional principles from Agile development and Third Stone's own experience with projects of varying size: From one developer working on a small- to medium-sized site to a team of developers making solutions for large to very large project scope.

Central to all of our approaches, however, is the idea of user stories and continual customer interaction in the development process. This is our cornerstone for ensuring satisfaction of customer expectations.
