It is easy to make the simple complicated. That is commonplace. It is difficult to make the complicated simple. That is art.
Too many organizations fail at Salesforce.com because the roadmap for driving processes becomes clouded by complexity and details. Adding superfluous fields creating numerous and disparate data relationships makes the database the central focal point rather than your people. Your people are trying to get things done. There is an inflection point where meaning can disappear and data entry takes precedence over productivity and sales effectiveness.
Success in Salesforce.com requires a focus on convergence. There should be a central focal point to drive the architecture and customization of the system. The opposite is divergence. The minutiae of adding more selections without purpose can overwhelm your team and prevent successful adoption.
Convergence requires leadership. It requires a clarity of thought and execution on how to capture your processes and make them work without friction in Salesforce.com. The system works. The question is whether it converges or diverges in its use cases.
