Quantitative Schedule
Risk Analysis

TBZ Group helps project teams understand programme uncertainty and assess the likelihood of achieving key milestones. Our quantitative schedule risk analysis identifies the main drivers of completion and supports informed decisions on programme commitments, mitigation priorities and time contingency.

How we support your project

Programme review

We review programme logic, calendars, constraints and milestone definitions to assess whether the schedule provides a suitable basis for risk analysis. We identify issues that could undermine the reliability of the results.

Risk modelling

We work with your project team to establish realistic duration ranges and relevant risk events. We document the assumptions behind the model and examine existing programme allowances to reduce the potential for double counting.

Risk reporting

We report the modelled probability of achieving key milestone dates and present completion forecasts at selected confidence levels, such as P50 and P80. Our reports explain the main risk drivers and support decisions on time contingency.

What you receive

Each assignment is tailored to your programme and the decisions you need to make. Depending on the agreed scope, deliverables may include:

  • Programme review findings and recommendations
