Quick Answer
Project management is the process of leading work to achieve goals within scope, schedule and budget. The two dominant approaches are Waterfall (sequential, plan-driven) and Agile (iterative, flexible). Most modern teams use a hybrid of both. Start with the methodology guide that matches how your team works.

Methodology Overview
Agile
An iterative approach that delivers work in short cycles, adapts to change and focuses on collaboration and customer value. Agile is not a single method — it is a mindset with many frameworks underneath it including Scrum, Kanban, SAFe and XP.

Framework Overview
Scrum
The most widely used Agile framework. Scrum organises work into fixed-length sprints, assigns three defined roles, runs five ceremonies and maintains three artifacts. Simple to understand, but takes practice to master.

Methodology Overview
Waterfall
A linear, sequential approach where each phase must be completed and signed off before the next begins. Still the dominant method in construction, engineering, government and highly regulated industries where requirements are fixed and well-defined upfront.

Approach Overview
Hybrid
A hybrid approach combines elements of both Waterfall and Agile — planning and governance from Waterfall, with iterative delivery from Agile. It is now the most common approach in large organisations and is explicitly tested in the PMP exam.

Technique Overview
Earned Value Management
EVM is a performance measurement technique that integrates scope, schedule and cost to give an objective view of project health. By comparing what was planned (PV) with what was earned (EV) and what was spent (AC), it enables accurate forecasting of final project outcomes.

PM Guides — 6 Common Questions
Project management is the process of leading the work of a team to achieve goals within a defined scope, schedule and budget. It involves five key phases — Initiating, Planning, Executing, Monitoring & Controlling, and Closing — and uses structured methodologies like Agile, Waterfall or hybrid approaches. See our complete beginner's guide →
Agile project management is an iterative approach that delivers work in short cycles (sprints or iterations), adapts to change and prioritises collaboration. Instead of planning everything upfront, Agile teams respond to feedback continuously. Common frameworks include Scrum, Kanban, SAFe and XP. See our full Agile guide →
Waterfall is linear and sequential — each phase is completed before the next begins. Agile is iterative and flexible — work is delivered in short cycles with continuous feedback. Waterfall suits projects with fixed, well-defined requirements. Agile suits projects where requirements are likely to change. Most modern organisations use a hybrid of both. See our full Agile vs Waterfall comparison →
EVM is a technique that measures project performance by comparing planned value (PV), earned value (EV) and actual cost (AC). It produces metrics like CPI (Cost Performance Index) and SPI (Schedule Performance Index) that tell you whether your project is on track, ahead or behind — and forecast what it will cost to complete. Try our free EVM calculator →
The five PMBOK process groups are: (1) Initiating — defining the project and getting authorisation; (2) Planning — establishing scope, schedule and budget; (3) Executing — carrying out the project plan; (4) Monitoring and Controlling — tracking progress and managing changes; (5) Closing — formally completing the project. See our full process groups guide →
Scrum is an Agile framework that organises work into fixed-length sprints (typically 2 weeks). It defines three roles (Product Owner, Scrum Master, Development Team), five ceremonies (Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective, Backlog Refinement) and three artifacts (Product Backlog, Sprint Backlog, Increment).
