Solved Problems On Critical Path Method
The Critical Path Method (CPM) is a project scheduling technique that helps determine the shortest possible time to complete a project. It identifies the critical tasks that must be completed in a specific order to avoid delays in the overall project timeline. In this article, we will dive into some solved problems on the Critical Path Method to showcase its practical application and effectiveness in project management.
Problem 1: Construction Project
Let’s consider a construction project that involves six major tasks: A, B, C, D, E, and F. The table below shows the duration of each task and the immediate predecessors:
| Task | Duration (days) | Predecessor |
|---|---|---|
| A | 3 | None |
| B | 4 | A |
| C | 2 | A |
| D | 5 | B |
| E | 6 | C, D |
| F | 3 | E |
To determine the critical path, we need to find the longest path through the project network. We start by calculating the early start (ES) and early finish (EF) for each task. The ES of the first task is always 0, and the EF is equal to the duration of the task. For the remaining tasks, the ES is the maximum EF of its predecessors, and the EF is obtained by adding the duration to the ES.
- Task A: ES = 0, EF = 3
- Task B: ES = 3, EF = 7
- Task C: ES = 3, EF = 5
- Task D: ES = 7, EF = 12
- Task E: ES = 12, EF = 18
- Task F: ES = 18, EF = 21
Next, we calculate the late start (LS) and late finish (LF) for each task. The LF of the last task is equal to the EF, and the LS is obtained by subtracting the duration from the LF. For the remaining tasks, the LF is the minimum LS of its successors, and the LS is obtained by subtracting the duration from the LF.
- Task A: LS = 0, LF = 3
- Task B: LS = 3, LF = 7
- Task C: LS = 3, LF = 5
- Task D: LS = 7, LF = 12
- Task E: LS = 12, LF = 18
- Task F: LS = 18, LF = 21
The critical path is determined by tasks with zero slack (LS – ES = 0). In this example, tasks A, B, D, and F are on the critical path, with a total duration of 21 days.
Problem 2: Software Development Project
Consider a software development project with the following tasks: Requirements Gathering (RG), Design (D), Development (Dev), Testing (T), and Deployment (Dep). The table below shows the duration of each task and the immediate predecessors:
| Task | Duration (weeks) | Predecessor |
|---|---|---|
| RG | 2 | None |
| D | 3 | RG |
| Dev | 5 | D |
| T | 2 | D |
| Dep | 1 | Dev, T |
To find the critical path, we follow the same steps as in the previous problem:
- Tasks RG, D, and Dev are on the critical path, with a total duration of 10 weeks.
Problem 3: Advertising Campaign
Let’s consider an advertising campaign with various tasks: Market Research (MR), Creative Design (CD), Content Creation (CC), Ad Production (AP), and Campaign Launch (CL). The table below shows the duration of each task and the immediate predecessors:
| Task | Duration (days) | Predecessor |
|---|---|---|
| MR | 2 | None |
| CD | 3 | MR |
| CC | 4 | MR |
| AP | 2 | CD, CC |
| CL | 1 | AP |
The critical path analysis for this advertising campaign yields the following result:
- Tasks MR, CD, AP, and CL are on the critical path, with a total duration of 8 days.
These solved problems on the Critical Path Method demonstrate its usefulness in project management. By identifying the critical tasks and their dependencies, project managers can prioritize their efforts and allocate resources efficiently. Understanding the critical path helps ensure timely project completion and minimizes the risk of delays.
According to a study, over 80% of projects that follow the Critical Path Method are completed on time. This highlights the effectiveness of this project scheduling technique in meeting project deadlines and achieving successful outcomes.
