Enterprise Transition Community | Glossary

Definition:

Enterprise Transition Community (ETC) is a small group in an organisation that supports the initiatives, efforts to introduce and improve Scrum. It exists to create a culture and environment where change can be released by members who are passionate about the success of the organisation. The acronym ETC is consistently used by Ken Schwaber in “The Enterprise in Scrum”.

It does this by not imposing changes but by guiding groups who are implementing changes, by removing obstacles, by creating energy and excitement for the change. The members of ETC are not more than a dozen but comes from the highest level involved in the transition to Scrum. If the company is adopting Scrum organisation-wide, the ETC should include senior people from Engineering, Development, VPs where the key is that ETC is made up of most senior people for the level at which transition is happening.

This is created around a concept with a image or keyword in the centre to which associated ideas are added as words, images connected through lines.

Mind maps are considered to be a type of spider diagram. Mind map was popularised by Tony Buzan a British psychologist, author and television personality. Buzan suggests few guidelines to create effective mind maps like starting at centre of blank sheet, using atleast 3 colours, images, symbols to be used, use of keywords, lines connected starting from the central image.

Keep the mind map clear using radial hierarchy or outlines to embrace branches. Mind maps are used as a simplified content management system.
