Below is some information about a project to implement a new manufacturing cell to assemble personal digital assistant devices. Note: this exercise is about the logical flow of the projects tasks. Map out the projects work using activity on arrow for success.TaskDuration EstimatesImmediate PredecessorsA. Determine process requirements2 weeksNoneB. Benchmark competitors processes4 weeksAC.
