👉PROJECT SCHEDULING IN A NUTSHELL

🕓 PERT (Program Evaluation & Review Technique)
Used when activity durations are uncertain.

⭐️It uses three time estimates:

• ⚡ Optimistic (O)
• ⚙️ Most Likely (M)
• 🐢 Pessimistic (P)
Formula → Te = (O + 4M + P) / 6

🎲Helps predict project duration and risk of delay.

🧭 CPM (Critical Path Method)
Used when durations are known.
It finds the longest path in the project network — called the Critical Path.
Any delay on this path = delay in the entire project!

📅 Scheduling Steps

1️⃣ List all activities.
2️⃣ Estimate duration & sequence.
3️⃣ Draw a network (PERT/CPM chart).
4️⃣ Identify the critical path.
5️⃣ Track progress using Gantt Chart, Primavera, or MS Project.

💡 Critical Path = Project Lifeline
💡 PERT = Handle Uncertainty
