Earned Schedule Myth

A LinkedIn Post Summary

Alex Lyaschenko addresses a common misconception surrounding Earned Schedule in Earned Value Management (EVM) discussions in a LinkedIn post. While some view Earned Schedule as a solution to EVM's time management issues, Lyaschenko argues that it only addresses one aspect, leaving other significant challenges unresolved. Earned Schedule introduces the concept of Time Performance Index (TPI) as a better proxy for project progress, but it does not provide reliable forecasts for project delivery dates, as it overlooks critical path considerations and changes in project risk profiles.

Lyaschenko also highlights several challenges beyond time management in EVM and Earned Schedule methodologies. He points out that traditional approaches fail to account for critical path activities, changes in risk profiles, and the evolving nature of projects through various stages. He emphasises the importance of analysing remaining work and project risks rather than solely relying on past performance for accurate completion date predictions, suggesting that performance metrics should be complementary rather than foundational in such analyses.
