Who Had A Bad Experience?• 91 ( 2.15% ) respondents had at least one really bad experience:

– 19 (0.45%) had much lower productivity

– 18 (0.43%) had much lower quality

– 73 (1.72%) had much higher cost

– 20 (0.47%) had much lower business satisfaction

• 709 (16.74%) had some bad experience– See above, plus:

– 140 (3.31%) had somewhat lower productivity

– 64 (1.51%) had somewhat lower quality

– 539 (12.72%) had somewhat higher cost

– 59 (1.39%) had somewhat lower business satisfaction

• There was a correlation between knowledge and results– E.g. The people knowledgeable with agile approaches had better quality,

stakeholder satisfaction, … than those who weren’t knowledgeable


Whence Modeling and Documentation?

• There was a statistical correlation between adoption of newer methods such as Agile Unified Process (AUP) or MSF Agile and adoption of Agile Model Driven Development (AMDD)

• Feature Driven Development (FDD) and Dynamic System Development Method (DSDM) have modeling, and arguably documentation, as explicit parts of the methods

• There was no correlation between adoption of Extreme Programming (XP) and AMDD– This leads me to believe that the question may not have

been clear to people, as many XPers are clearly taking an agile approach to modeling and AMDD came out of XP to begin with
