The right Forensic Schedule Analysis?

In Forensic Schedule Analysis, it's essential to understand the difference between prospective and retrospective methods and when to use each.

Prospective vs. Retrospective Analysis

Prospective Analysis:

• Purpose: To predict future impacts of delays on the project timeline.
• Use Case: Best used during the project to forecast and mitigate potential delays.
• Benefits: Helps in proactive decision-making. Useful for ongoing projects. Assists in preparing for future disruptions.

Retrospective Analysis:

• Purpose: To understand the impact of past delays on the project.
• Use Case: Best used after the project or when significant delays have occurred.
• Benefits: Provides a clear picture of what happened. Essential for resolving claims and disputes. Helps in learning lessons for future projects.

Methods of Forensic Schedule Analysis

1. Time Impact Analysis (TIA) - Prospective:

• Adds the impact of delays to the original schedule to see how the project timeline changes.

Salient Points:

• Predictive Approach: Looks forward to predict the impact of potential delays.
• Decision-Making Tool: Helps justify time extensions and forecast future project performance.
• Claim Support: Provides a basis for negotiating claims for time extensions and additional costs.

2. Static As-Planned vs. As-Built - Retrospective:

• Compares the original planned schedule with the actual schedule.
• Simple Comparison: Highlights deviations from the original plan.
• Clear Accountability: Easy to identify discrepancies and responsible parties.
• Ideal for Minimal Changes: Best for projects with fewer changes and straightforward timelines.

3. Windows Analysis - Retrospective:

• Breaks the project timeline into windows (time periods) and analyzes delays within each window.

Salient Points:

• Detailed Examination: Provides a period-by-period analysis of delays.
• Identifies Responsibility: Helps pinpoint when and who caused delays.
• Complex Projects: Suitable for projects with multiple phases and overlapping delays.

Choosing the Right Method

The choice between prospective and retrospective analysis depends on your project's stage and the nature of delays. Prospective analysis, like TIA, is invaluable for ongoing projects needing future delay predictions. Retrospective methods, such as Static As-Planned vs. As-Built and Windows Analysis, are essential for understanding past delays and resolving claims.

Each method, as guided by the SCL protocol, plays a critical role in effective project management, ensuring accurate analysis and mitigation of delays.
