To promote open access to information use story cards; that are public property, as is visible documentation of all status information such as the tracking data. Collective code ownership encourages everyone to contribute to the project. Customer and developer are placed in close proximity via on-site customer to promote an open exchange of information.
To promote open information, try a variety of techniques like:
• Place team members within close proximity of each other whenever possible.
• Make use of information radiators such as whiteboards, charts, etc to disseminate information
• Rather than have status meetings with the project sponsor(s) in an office or conference room, bring him/her to the project room for public status reports and hands-on demos.
• Use a team wiki (free form web site written by users) to share information.
• Establish daily status meetings to promote the flow and exchange of information.
• Sustain open information exchange between business domain experts and the development team.
