Salesforce.com underwent a major enterprise-wide transformation to Agile Development Methodology (ADM) over 3 months in order to address issues like a lack of visibility, resource bottlenecks, and unpredictable release dates that were causing customer unhappiness and a decline in productivity. This "Big Bang" approach resulted in significant improvements like a 61% reduction in time between major releases, a 94% increase in delivered feature requests, and a 38% increase in features delivered per developer. While the transition was challenging and faced some initial resistance, continuous improvements and refinements over time helped ensure the success and sustainability of the new Agile approach.
