PMP Tutorial | Critical Path Method, Forward Pass and Backward Pass Are Explained with PMP Question

BlindTutor.com presents: 📘 In this video, you are gonna see what the Critical Path Method (CPM) is, including Forward Pass and Backward Pass calculations, and we’ll solve a real PMP-style question about it together 🎯 The Critical Path Method (CPM) is a schedule analysis technique used to determine the longest path through a project network diagram 🔥The Critical Path represents the shortest possible time needed to complete the project. 🔹 What it does: identifies the project's critical activities 🎯 determines project duration ⏳ calculates float (slack) 📊 highlights activities that cannot be delayed without delaying the project 🚨 🔹 Forward Pass The Forward Pass is used to calculate: ✅ Early Start (ES)✅ Early Finish (EF) It answers the question: "When is the earliest this activity can start and finish?" ⏩ Formula: EF = ES + Duration Rule:Start from the beginning of the network and move forward ➡️ 🔹 Backward Pass The Backward Pass is used to calculate: ✅ Late Start (LS)✅ Late Finish (LF) It answers the question: "When is the latest this activity can start and finish without delaying the project?" ⏪ Formula: LS = LF - Duration Rule:Start from the end of the network and move backward ⬅️ 🔹 Float (Slack) Float is the amount of time an activity can be delayed without delaying the project ⏳ Formula: Float = LS - ES = LF - EF Activities on the Critical Path have: ✅ Float = 0 🔹 Simple Example 🏠 Activities: A (Foundation) → 5 daysB (Framing) → 3 daysC (Roofing) → 2 days Path: A → B → C Project Duration: 5 + 3 + 2 = 10 days Since all activities are on the longest path and have zero float, they form the Critical Path 🔥 🎯 Forward Pass calculates the earliest dates, Backward Pass calculates the latest dates, and together they help identify the Critical Path and schedule flexibility within a project 🚀 For Complete PMP Tutorial, Check out: BLINDTUTOR.COM #NavEskand #BlindTutor #blindtutor.com #FreePMPTutorial #PMP #PMPCertification #ProjectManagement #PMI #PMPExam #ProjectManager #PMPLessons #PMPPrep #PMPTraining #PMPStudy #PassPMP #PMPExamPrep #PMP2026 #PMPStudyPlan #PMPTips #PMPTricks #PMPSuccess #PMPMockExam #PMPQuestions #PMPBootcamp #Agile #Scrum #Waterfall #ProjectPlanning #RiskManagement #ScheduleManagement #PMBOK #AgilePM #HybridProjectManagement #CAPM #PMPMindsets #FreeCAPMTutorial #PMBOK6 #PMBOK7 #PMBOK8 #Agilepracticeguide #FREEPMPMockexam #FREEPMPTEST #PMPMindsets #mindset #PMPQuestion #PMPPracticeTest
