The overarching theme of the Lightning Project implementation is to migrate our teams onto the awesome new Lightning Experience UI where possible. We have to analyze the current state and understand the limitations of Lightning Experience UI (such as it does not support custom Java and URL buttons yet!).
Our deliverable will include a full analyses and milestone project plan and a rollout project plan with go-live dates and a communication plan for the affected users (including training schedule!). Everything you need to get started is in the plan, take a look and start modifying to meet the requirements of your org!!
