In part 2 of a Case Study about Thursday 22nd February 2024 – specifically looking at Aggregate Dispatch Error across all Semi-Scheduled units (and in this part 2 looking just at 14:15).
Finding some time to make some progress in compiling GenInsights Quarterly Updates for 2024 Q1, here’s a short Case Study of Thursday 22nd February 2024 (a day that saw significant collective under-performance of Semi-Scheduled units with respect to their Targets).
Also from GenInsights Quarterly Updates for 2023 Q4, the particular case of Tuesday 31st October 2023 is also worth sharing (and a broad audience understanding).
Returning a focus to GenInsights Quarterly Updates for 2023 Q4, here’s a particular example from Sunday 24th December 2023 worth sharing (and a broad audience understanding).
