The Real ServiceNow Implementation Timeline: Why Six Months Rarely Means Six Months
A COO signs a Statement of Work in January. The SI has quoted a 24-week ServiceNow implementation timeline, ITSM Pro plus a light ITOM footprint, go-live in early July. She circulates the plan internally. Marketing pencils in a launch webinar. Finance builds the licence spend into the Q3 forecast. HR schedules the change-comms rollout. By late April the delivery lead sends the first quietly worded status note. Discovery took longer than planned because the CMDB source data was worse than anyone admitted. Two integrations were re-scoped when the SAP team said their middleware team is booked until September. Change requests are stacking up. The July date is now "at risk". By June it has slid to October. By October it is November with a phased approach. The webinar is cancelled. None of this is unusual. It is the average ServiceNow implementation timeline for a mid-market rollout done properly. The problem is that almost nobody quotes it that way at the sales stage, so every project starts with a plan that was already fiction on the day it was signed.
