Agile Evaluation Framework or Agile: EF was introduced by Krebs and Krell in 2008, an approach to assess how well agile teams are doing. Here they advice to keep things simple and is therefor less of an actual framework than a process for assessing teams.
In this approach Krebs and Krell suggest having team members complete a very short questionnaire at the end of every sprint. Each question concerns an agile practice which is answered with a score in range of 1 – 10, where 10 indicates done 100% of the time and 1 indicating never done. The assessment may be reported in a graph where solid bars indicate the team’s result. The darker, thinner line indicates how widely opinion vary, calculating standard deviation.
