9.  Common Challenges to Effective Risk Analysis

 1.    Objectives

Learn internationally-recognized best practices for managing project risks

Assess the potential variability in project duration resulting from identified project risks

Assess how risks and opportunities may influence the project schedule

Understand which paths in the schedule have the highest probability of impacting the schedule completion or key milestones

•Understand which risks have the most impact on overall schedule variability

2.    A brief to Schedule Risk Analysis

You may have said to yourself something like:-

• “If it goes well,we will have that foundation completed in 10 days, but there is a chance the ground could be rocky and it may even take 20 days, but that is really the worst-case and is unlikely. So my best guess is 13 days”

• So in your project schedule you enter13 days against the task "Foundation". The other information (i.e. the best case estimate of 10 days and worst-case estimate of 20 days) are not entered into the project at all


• By entering only the most likely duration a lot of additional information that would be of great benefit in producing a much more realistic plan is lost


Using risk analysis allows you to easily enter extra information about the uncertainty of the duration of your tasks.


This extra information can be used to produce more accurate and realistic schedules. It can also help you manage your project more effectively by answering questions such as:

• What is the chance of finishing the project on time?

• What date can I be 90% confident of finishing by?

• What tasks are most likely to cause project delay?

3.    Risk Analysis Software

Primavera Risk Analysis uses advanced Monte Carlo-based cost and schedule analytics to provide full-lifecycle risk management through risk models: estimate uncertainty, probabilistic branching, fixed-cost

uncertainty, variable-cost uncertainty, resource uncertainty and weather modeling.


Some major customers using Primavera Risk Analysis as part of the ongoing project management process:


• ExxonMobil, Petronas, ARAMCO, SABIC, TOTAL

• British Petroleum

• Shell, ONGC, Qatar Gas

• DoW Chemical

• BASF

• Santos

• Siemens,

• Worley Parsons

• Fluor, Saipem

• Technip, Techinicas Reuidas

• Bechtel, JCC, CCC

• Samsung, Hyundai, GE, SK, Doosan

• Etc….

4. Influential Factors and Project Specifics

Every project has its own unique risks that need to be managed

5.    The Three Levels of Risk Assessment

Level 1: Risk Identification is the formal act of identifying risks and opportunities for a project. Typically, this includes the use of a risk checklist and/or the start of a project risk register

 Level 2: Deterministic Risk Analysis is the act of analyzing risks through a single-point estimate of potential impacts. Typically, this involves a probability x impact matrix and a prioritized lists of risks

 Level 3: Probabilistic Risk Analysis is the act of analyzing risk through probability distribution estimates of potential impact, known as Monte Carlo simulations. Typically, this approach involves the determination of the probability of meeting project targets

6.    Project Risk Factors Checklist

7.  Minimum Conditions of Satisfaction

There are certain conditions required before starting the Schedule

Risk Analysis:  Scope of work, execution plan, cost estimate, and schedule consistent with each other

 A quality schedule : that includes activities for all project scope; has realistic durations for activities; has logic links that reflect the sequence of work and the dependencies between activities, and realistic critical and near-critical paths

 A team-approved schedule :  A risk register with a comprehensive list of all identified project-specific risks, an understanding of the likely impact of each of those risks, and risk response actions for each risk

Logic Tie Considerations

• How duration variability in B any sequence passes from one activity to another depends on the logic ties that are used to connect these two activities.

• The types of logic ties used in the schedule risk model will have a significant impact on the results of the risk model in a Monte Carlo simulation


• The triangles included in the figures represent the duration variability of the activity



8.  Schedule Risk Modeling (Case Study)


• What is the project context?


• What is the chance of finishing the project on time?


• What chance do we have of finishing the project in Q4 2021?

• What date can be P50 Scheduling and Pertmaster for risk analysis or most likely scenario?


• What date can be P90 Scheduling and Pertmaster for risk analysis or worst-case scenario?

• What tasks are most likely to cause project delay?


• What are the major risks delaying the project?


• What will be the finish date after risk mitigations?

9.  Common Challenges to Effective Risk Analysis

• Dangers of double-counting risks

• Danger of missing important risks

• Danger of ignoring secondary risks

• Danger of using deficient schedule

• Disconnection between risk rating scales and project objectives

• Inclusion or not of rare (catastrophic) events

• Too many different risk assessments are performed across the organization

• The amount of information and data gathered is difficult to interpret and use.

Each country pavilion will give the visitors a taste of their distinctive culture, growth, and future vision.

What are the Three Main Pavilions at Dubai Expo 2020?

The three main pavilion groups at Expo 2020 Dubai are the following.
1. Mobility District

This sub-theme has different topics, like digital connectivity, logistics, and travel exploration. Mobility district explores the concepts of connections, human progress, etc. The pavilions in the mobility district explore connections that drive the world ahead and how to eliminate the divide between physical and digital worlds. Visitors can explore future vehicles, developments in space exploration, and innovative mobility devices.
2. Sustainability District

The sustainability district explores the balance in the world we inhabit to ensure a sustainable future. The main aim is to motivate people to join small actions that grow into positive global movements that will help preserve the world around us.

You can explore how the country aims to achieve its vision of becoming a trading hub that connects Africa to the world.
7. Belgium

The Belgian pavilion reflects the country’s status as a European mobility powerhouse. The lush Green Arch facade is the main talking point here as it promotes biomimicry, a concept in which solutions to modern-day problems are modelled after nature. Visitors can explore Belgium’s industrial, technological and scientific know-how, reflecting ‘belgitude’, a mix between Latin romanticism in art and Anglo-Saxon technical precision in the industry.
8. Jamaica

At Jamaica’s country pavilion, guests can meet some of the country’s most famous athletes while learning about their lives and taking in the country’s rich art and culture.

6. Seychelles

You can participate in a treasure hunt beneath the waters at the Seychelles expo pavilion. Visitors are accompanied by a strong theme of preservation throughout the tour, and the quest is as entertaining as it is educational. Visitors can literally discover a treasure untouched by men and that money can’t buy – The Seychelles Islands! Holiday destinations researchers make up most of the visitors to the Seychelles pavilion and in two weeks of opening, more than 7,800 visitors have been recorded.

7. The Netherlands

The Netherlands expo pavilion presents a cone-shaped vertical farm that creates its own microclimate while gathering water, food, and electricity.

Final Thoughts

Since the world’s first Expo in London, these gatherings have facilitated worldwide collaboration while making significant contributions to design and architecture. As we saw, the Dubai Expo is the most remarkable expo to date, in terms of scale and innovation. There’s no question that the design world will keep talking about these remarkable pavilions until Osaka hosts Expo 2025, which will include even more thought-provoking and creative architecture.
