Agile Considerations and Emerging Practices
Among some of the newer emerging practices in the project management profession is the expansion of earned value management concepts. Earned schedules (ES) has surfaced as an adaptation to the schedule variance (SV) measure to include ES - AT (actual time) where a calculated result greater than 0 indicates the project is ahead of schedule, and a value less than 0 indicates the project is behind schedule. The schedule performance index (SPI) can also be adapted with this approach using ES/AT to indicate the project’s efficiency of executing the work. Similar to the existing SPI result interpretation, a value greater than 1 indicates an efficiency better than project schedule, while a value less than 1 indicates an efficiency leaving the project behind schedule.
Earned schedule (ES) and actual time (AT) offer an emerging variant
to the schedule variance (SV) calculation, where;
SV = ES - AT
