What is the typical time frame for an ERP Implementation consisting of Finance, HR, Supply Chain and Production in a mid-sized multinational organisation?

A period of 18 to 24 months in a traditional roll-out is the reasonable time frame for a complete roll-out of an ERP implementation consisting of all the key modules. The process can be streamlined and optimized to incorporate best-of-breed, pre-integrated, and cloud base solutions in a shared eco-system model. The best-of-breed solutions focus on Ease of Onboarding, Ease of Integration, and Ease of Change Management, especially in the Supply Chain and Finance areas. The business doesn't have the luxury to wait for a long duration and expects a 3x to 4x faster roll-out to see immediate benefits and productivity improvements in 3 to 6 months. The system players who are able to solve the implementation timeline problems at a faster rate, will surely be a disruptor in the ERP implementation process.
