Understanding Windows Analysis for Delays and Extensions of Time (EOTs)

In the world of project management, delays are often inevitable. Understanding how to analyze these delays effectively can significantly impact the outcome of a project, especially when it comes to claiming Extensions of Time (EOTs). One method widely used for this analysis is Windows Analysis.

What is Windows Analysis?

Windows Analysis is a technique used to evaluate delays in a project schedule. It breaks down the project timeline into specific "windows" or segments, allowing project managers to isolate and analyze delays more accurately. This method helps in determining whether the delays were caused by the contractor, the client, or other external factors.

Step 1: Define Your Time Windows

To begin, divide your project timeline into distinct windows, typically ranging from two weeks to one month. Each window will serve as a segment for detailed analysis.

1. Identify key milestones or phases of your project.
2. Establish timeframes for each window based on these milestones.

Step 2: Gather Schedule Data

Collect all relevant data regarding the project schedule. This includes:

1. Baseline schedule: The original project plan.
2. Updated schedules: Any revisions made during the project.
3. Daily reports: Documentation of any delays and their causes.

Having this information readily available is crucial for an accurate analysis.

Step 3: Analyze Each Window

For each defined window, analyze the activities and their respective statuses:

1. Compare the baseline schedule with the actual progress for each window.
2. Identify delays: Determine which activities fell behind schedule and categorize the causes (e.g., weather, resource availability, client changes).
3. Document findings: Keep detailed notes on the delays, including their impact on subsequent activities.

Step 4: Determine Responsibility for Delays

After analyzing the windows, determine who is responsible for each delay:

1. Assess the causes: Was the delay due to factors within the contractor’s control or external influences?
2. Establish entitlement: This will form the basis for your EOT claim, showing that the delays were not the contractor’s fault.

Step 5: Claim Extensions of Time (EOTs)

With the analysis complete, you can now prepare your EOT claim:

1. Compile your findings: Summarize the delays and their responsibilities in a clear format.
2. Provide supporting documentation: Attach relevant data, including schedules, daily reports, and communications.
3. Submit the claim: Present your claim to the relevant stakeholders, following the project's contractual procedures.

Conclusion

Windows Analysis is a powerful tool for managing delays and claiming Extensions of Time in project management. By systematically breaking down the project timeline into windows, collecting relevant data, and analyzing each segment, project managers can effectively assess delays and establish clear responsibility. This approach not only aids in claiming EOTs but also improves overall project control and transparency.
