One platform to run the whole company is everlasting dream and obsession of IT world. Many companies consider it a blessing to decrease a number of deployed IT solutions. Few, however, think that it is exactly this diversity and complexity that ensures stability and flexibility of corporate IT systems.
Blind reliance on a single, even perfect in every way, solution is among most deadly illusions capable of destroying a successful business. Objective versatility of IT landscape, which appears with time in every company, is a natural safety belt against dependency from a single vendor and powerful long term reservation strategy.
Growing complexity of corporate IT system is an objective reality expressing increasing complexity of the business in digital age. Any attempts of artificial simplification of this complexity lead to degradation of the whole business infrastructure.
The epoch when one hero warrior (or worker, or system) was able doing every mission have gone forever. We live in the time of deepening specialization. It concerns IT same or more than any other sphere of business. Be prepared to manage more IT solutions in your organization day to day.

There always exists a discrepancy between a model of business process, however well designed and accurate, and real execution of this process in a business environment. The reason for this gap is an unforeseen depth and hidden details inherent to any real process. Real business model of organization is ultimately unlimited in its depth. Going from highest management levels, it descends to individual departments, client relations, production units, technical code of equipment and controllers etc. In vast majority of cases, it is impossible and senseless to build a complete model covering all and every fine detail of the business. Omitted lower layers of the model create (pseudo) random fluctuations during execution of the model. Real execution paths of a process never follow its model exactly. However, in case of the correct model, we can expect to see that an ensemble of execution paths statistically converges to the model as to its average path over a significant set of observation...
