LEARNING HUB
Project Management Tools
Explore reviewed PMP and project-management guidance, practical examples, and connected tools.
CPI and SPI Calculator ↗
Calculate cost and schedule performance indexes from earned value data, then interpret efficiency without confusing value-based schedule results with time.
Communication Channels Calculator ↗
Calculate the number of potential one-to-one communication channels in a group and understand why the formula is not a workload forecast.
Critical Path Method Calculator ↗
Calculate a simple finish-to-start network duration and critical activities from activity durations and predecessors, with clear scope and model limitations.
EAC and ETC Calculator ↗
Forecast estimate at completion and estimate to complete from BAC, EV, and AC when current cost efficiency is expected to continue.
Earned Value Management Calculator ↗
Calculate CV, SV, CPI, SPI, and a CPI-based EAC while learning what each earned value result means and which assumptions limit the forecast.
PERT Three-Point Estimation Calculator ↗
Calculate a PERT expected estimate, standard deviation, and variance from optimistic, most likely, and pessimistic values using consistent units.
Project Schedule Variance Calculator ↗
Calculate earned-value schedule variance and SPI, then interpret results in value units without presenting schedule variance as days or weeks.
Risk Probability and Impact Matrix ↗
Calculate an illustrative probability-impact score and priority band while preserving organization-specific scales, thresholds, and risk appetite.
