In project management, where stakes are high and mistakes can be costly, being able to foresee, spot, and fix delays is crucial. Delay analysis is a key tool in this process. It helps project managers and legal teams make informed decisions and keep projects on track.
This article looks at why delay analysis matters. It explains how it can reduce uncertainty and shows best practices for proactive management. It also highlights how project managers can strategically adjust plans to better serve the client.
I. Understanding the Origins of Schedule Impacts
Project delays can happen for many reasons. These include incomplete initial planning that makes decision-making difficult, unexpected changes in project scope, geotechnical issues, or underestimating the resources needed.
A careful delay analysis does more than identify causes. It also shows how delays affect the whole project according to the planned schedule. This involves looking at how tasks depend on each other and how a delay in one area can slow down overall progress.
II. Tools and Methods of Analysis
Modern project management tools, such as Primavera P6, Oracle Primavera Cloud, and Tilos for linear scheduling, offer advanced features for delay analysis.
These tools allow project teams to extract useful information about project events from their databases. In some cases, this data is transferred into simple spreadsheets, like Excel, to make it easier to understand.
Ultimately, the approach to delay analysis depends largely on the quality of information provided by the client.
III. Strategies for Mitigating and Negotiating Delays
After analysing the causes and impacts of delays, it is important to prepare a claim report. This report covers all the points to discuss and renegotiate with the client.
The claim report is an important document in contract and claims management for projects. It is used to record all claims related to delays, costs, and project execution conditions. The goal of the claim report is to:
- Document impacts: It explains each event that affected the project, showing the causes, consequences, and responsibilities.
- Support requests: It provides evidence and analysis to justify requests for financial compensation or extra time.
- Prepare negotiations: It is a base for discussions with the client, partners, or in legal disputes.
- Follow contract rules: It ensures that all actions follow contract clauses and legal obligations.
IV. Training and Skills in Delay Analysis

Analyzing delays requires special skills and a good understanding of the methods used. Delay analysis uses several methods:
Total impact method: Overall evaluation of project disruptions
Time window method: Detailed analysis of changes in the critical path. This method requires careful attention and analysis.
Impact on planned schedule method: Comparison between the initial schedule and the real situation
Usually, the method used is mentioned in the client contract.
V. Conclusion
Given the complexity of projects and the difficulty of meeting contractual commitments, delay analysis is therefore an indispensable component to defend the interests of the holders or clients (Project Owners).
Indeed, 80% of complex, large-scale projects are subject to delay analyses. These analyses are essential for informing strategic reorientation for each stakeholder.
Moreover, support from experts can significantly assist in producing a defense argument in the form of claim reports. As a result, this maximizes the chances of success by transforming the challenges posed by delays into opportunities for project optimization.
