Yellow Belts conduct projects within their work area. Yellow Belt projects are of low complexity and normally yield lower financial returns than either Green Belt or Black Belt projects. Yellow Belts need to be sufficiently knowledgeable in six sigma concepts and principles to support Green Belt in defining processes, gathering data, solving simpler work related problems, implementing changes, and keeping controls in place to maintain the gains. Yellow Belts may be team members in Yellow Belt or Green Belt project teams. Yellow Belts are well versed in their job processes, and are proactive in identifying and analysing problems. People suitable for Yellow Belt training are those who are either already in work group leadership roles or those who are being ear marked for such positions.
