ECRS is a lean tool used to analyze a process and remove the non-value added steps from it. It stands for Eliminate, Combine, Rearrange and Simplify. This also happens to be the order in which the solutions are to be designed - first try and eliminate, if not, then combine or rearrange or simplify.
Eliminate - Remove or get rid of the steps.
Combine - When steps cannot be eliminated, then seek to combine multiple steps into one.
Rearrange - Reorder the steps to smoothen the flow.
Simplify - Uncomplicate the steps.
