Revenue From Contract With Customer [Abstract]

Schedule of Reportable Segment Revenues, Disaggregated by Revenue

The following table presents the Company’s reportable segment revenues, disaggregated by revenue type. The Company disaggregates revenue from contracts with customers into major services lines. The Company has determined that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The Company’s reportable segments are Maintenance Services and Development Services. During the second quarter of fiscal 2021, the Company reclassified revenue related to a second quarter fiscal 2020 acquisition from the Maintenance Services segment to the Development Services segment to align with changes in how we manage our business. Prior period segment results have been reclassified with no significant impact on Net service revenues. See Note 15, “Segments”.
