Exercise: Early Finish Calculation

Scenario:

You are managing a project with the following activities and their dependencies:

• Activity A: Duration = 2 days (Start of project)
• Activity B: Duration = 3 days (Dependent on Activity A)
• Activity C: Duration = 4 days (Dependent on Activity B)
• Activity D: Duration = 1 day (Dependent on Activity C)

The project starts on May 1st.

Techniques

Chapter 1: Techniques for Calculating Early Finish

This chapter delves into the various techniques employed for calculating Early Finish dates in project management.

1.1 Forward Pass Method:

The most common approach is the Forward Pass method, described in the introductory text. It involves moving forward through the project schedule, activity by activity, calculating Early Finish based on the Early Start and activity duration.

1.2 Critical Path Method (CPM):

The CPM is a powerful technique that identifies the critical path, a sequence of activities where delays would directly impact the overall project completion.

• Early Finish Calculation in CPM: Within the CPM, Early Finish dates are calculated for each activity along the critical path. Any delay in an activity on the critical path directly impacts the project's overall finish date.

1.3 Precedence Diagramming Method (PDM):

The PDM uses a network diagram to visually represent project activities and their dependencies.

• Early Finish Calculation in PDM: In PDM, the Early Finish date of an activity is calculated by considering the latest Early Finish date among all its preceding activities. This method helps visualize activity dependencies and facilitates accurate Early Finish calculations.

1.4 Other Techniques:

• Gantt Charts: While not a direct calculation technique, Gantt charts visually represent project timelines, including Early Finish dates, allowing for easy project progress tracking.
• PERT (Program Evaluation and Review Technique): PERT utilizes statistical analysis to estimate activity durations, incorporating uncertainty and risk. Early Finish calculations in PERT account for potential delays and variations in activity completion times.

1.5 Importance of Accuracy:

Accurate Early Finish calculations are crucial for:

• Realistic Project Scheduling: Avoiding unrealistic deadlines and setting achievable goals.
• Resource Allocation: Ensuring resources are available at the right time.
• Risk Management: Identifying potential bottlenecks and taking proactive measures to mitigate risks.

1.6 Conclusion:

This chapter explored various techniques for calculating Early Finish dates. Choosing the appropriate technique depends on the project's complexity and the need for accuracy and risk management.

Chapter 2: Models for Early Finish Calculation

This chapter delves into the mathematical models used to calculate Early Finish dates, providing a deeper understanding of the underlying principles.

2.1 Basic Formula:

The core formula for calculating Early Finish is:

Early Finish = Early Start + Activity Duration

2.2 Applying the Formula:

• For the first activity, the Early Start is usually the project start date.
• For subsequent activities, the Early Start is determined by the latest Early Finish date among its predecessors.

2.3 Network Diagram Approach:

Network diagrams, often used in CPM and PDM, depict activities and their dependencies.

• Forward Pass Calculation: Using a forward pass analysis, one can traverse the network diagram, starting from the first activity, and calculate Early Finish for each activity based on the formula.

2.4 Example:

Consider a project with three activities:

• Activity A: Duration = 3 days (Early Start = Day 1)
• Activity B: Duration = 2 days (dependent on Activity A)
• Activity C: Duration = 4 days (dependent on Activity B)

Using the formula:

• Early Finish (A) = 1 + 3 = Day 4
• Early Finish (B) = 4 + 2 = Day 6
• Early Finish (C) = 6 + 4 = Day 10

2.5 Importance of Dependencies:

Accurate representation of activity dependencies is crucial for accurate Early Finish calculations.

• Incorrect Dependencies: Misrepresenting dependencies can lead to inaccurate Early Finish calculations, resulting in unrealistic schedules and potential delays.

2.6 Conclusion:

This chapter discussed the underlying mathematical models for calculating Early Finish dates, emphasizing the importance of accurate activity duration estimation and dependency representation.
