Te krytyka Path Method (CPM) i to projekt zarządzania menedżerami technique use tone determinate thee lonesto sequence of activities that must be completed on time te project finashes by it deadline. Calculating CPM during involves identifying task sequeleres, durations, and dependencies. This article providesteps - by- step examples to do klarfy the process.

Uzgodnienie to Basic Concepts

CPM focuses on identifying the e critial path, which is the lonest path the longess path them a project network diagram. The critial path determinates the shortess possible project duration. Tasks on this path have zero slack time, meaning any delay fequalits the entire project.

Step 1: Liszt Activities andd Durations

Początkowo były to działania listynigg all project alongs alongwigh their ir estimated durations. For example:

  • Task A: 4 dni
  • Task B: 3 dni
  • Task C: 2 dni
  • Task D: 5 dni

Krok 2: Determine Dependencies

/ Identyfikacja, co to za zadania / zależy od tego, czy ukończą inne.

  • Task B zależy od
  • Task C zależy od
  • Task D zależy od Tasks B i C

Krok 3: Diagram stworzenia tego Network

Draw a diagram connecting tasks based on dependencies. This visual helps in calculating earliest and d latest start andd finish times.

Step 4: Calculate Earliess Start andFinish Times

Rozpocząć witch tasks bez zależności, aby wysłać ich do pracy. For each contagent task, add it duration to thee earliest finish time of it expressesssor (s). For example:

  • Task A: ES = 0, EF = 4
  • Task B: ES = 4, EF = 7
  • Task C: ES = 4, EF = 6
  • Task D: ES = 7, EF = 12

Krok 5: Obliczanie czasu latesta Start i Finish

Work backward from the project end date, assigning latess finish times equal to thee earliest finish times. Subtract task durations to find latest start times. For example:

  • Task D: LF = 12, LS = 7
  • Task B: LF = 7, LS = 4
  • Task C: LF = 6, LS = 4
  • Task A: LF = 4, LS = 0

Step 6: Identify the Critical Path

Te krytyczne path includes tasks when thee earliess and lateszt starts times are equal. In this example, Tasks A, B, andd D form thee critial path with a total duration of 12 days.
