Project Scheduling

Basic idea

Plan-driven and Agile invert which side of the iron triangle is fixed: Waterfall fixes scope and estimates cost+time; Agile fixes cost+time and estimates features. Different planning artefacts follow.

Key facts

• Waterfall: scope fixed → estimate cost & time → schedule (Gantt / PERT).
• Agile: cost & time fixed → estimate features → backlog + sprints (no project schedule).
• Mixed (hybrid) approaches are increasingly common.

Waterfall

Constraints: Scope Estimates: Cost and Time
