Alexei Zheglov is a software consultant and co-creator, with Anderson, of the Fit for Purpose framework documented in fit-for-purpose. The framework extends the kanban-method into product management territory, providing fitness-criteria — metrics for evaluating whether a service meets customer expectations — as the bridge between flow management and business outcomes.
Zheglov's contribution to the maturity-and-enterprise-era of Anderson's work reflects the method's evolution from a team-level flow management tool toward a comprehensive approach to organizational fitness and customer value delivery.
