Earned Value Management (EVM) is a technique used to assess project performance by comparing the planned progress with actual progress. It helps in tracking the project's cost and schedule to identify any variances, allowing you to make timely adjustments to ensure the project stays on track. EVM is an essential tool for determining whether the project is under or over budget and if it is ahead or behind schedule.

Task Dependency Mapping involves creating a Network Diagram, which visually represents the sequence and relationships between tasks. It outlines which tasks need to be completed before others can start (dependencies) and helps identify the flow of the project. This ensures efficient task scheduling and resource allocation.

PERT (Program Evaluation and Review Technique) is used to plan and schedule tasks that have uncertain durations, typically with a focus on estimating the time needed to complete the project. On the other hand, CPM (Critical Path Method) helps identify the longest sequence of tasks that determine the project duration, highlighting the critical path. Both methods help with project scheduling by providing insights into timelines, risks, and critical tasks.

Scope Definition involves clearly outlining the project’s objectives, deliverables, and boundaries to ensure everyone involved understands what is expected. It sets the foundation for planning the project schedule, budget, and resources. Proper scope definition ensures that the project remains focused, prevents scope creep, and ensures that all project activities are aligned with the initial goals.
