In terms of KPI's, the standard is covered given the appropriate configuration (Plan-vs-Actual,WC Productivity,Backlog MH,%BreakDown Work,%Overtime, etc.).
In terms of configuration it depends on the KPI's you pick (i.e. Plan-vs-Actual will require confirmation of GoodsIssue for Stock Material, the use of electronic Time Sheets and of course use of confirmation to log any other activites performed(bottom line:appropriate codification of activities, items, and damage codes will be required)).
In terms of functionalities you will be required to maintain revisions,work centers, and may even need personnel masters.
