Have you ever wondered how you could be calculating risk in investments and engineering projects? Risk is a term that describes the uncertainty of the outcomes of an action or a decision. The risk can be measured by the probability and the magnitude of the potential losses or gains. Risk can be found in many domains, such as investments and engineering projects, but how are they calculated and compared?

In this article, I will explore the methods and challenges of calculating risk in these two fields, and how they differ from each other. I will also provide some examples and tips on how to manage risk effectively and efficiently.

## Calculating Risk in Investments and Engineering Projects – Investments

Investments are financial assets that are expected to generate returns in the future. Examples of investments include stocks, bonds, mutual funds, real estate, and cryptocurrencies. The risk of an investment is the possibility that the actual return will be lower than the expected return, or even negative. The risk of an investment depends on various factors, such as market conditions, economic trends, political events, company performance, and investor behavior.

## How To Calculate? Calculating Risk in Investments and Engineering Projects

One way to calculate the risk of an investment is to use the standard deviation, which is a statistical measure of how much the returns vary from the average. The higher the standard deviation, the higher the risk. For example, if an investment has an average return of 10% and a standard deviation of 5%. It means that 68% of the time, the return will be between 5% and 15%, and 95% of the time, it will be between 0% and 20%. However, this method assumes that the returns follow a normal distribution, which may not be true for some investments. Especially those with extreme outcomes.

Another way to calculate the risk of an investment is to use the value at risk (VaR). Which is a measure of how much money an investor can lose in a given period with a certain probability. For example, if an investment has a VaR of $10,000 at a 95% confidence level for one day. It means that there is a 5% chance that the investor will lose more than $10,000 in one day. However, this method does not tell us how much more than $10,000 the investor can lose. Which can be very large in some cases.

## Calculating Risk in Investments and Engineering Projects – Engineering

Engineering projects are activities that involve designing, building, testing, and operating systems or products that meet certain specifications and requirements. Examples of engineering projects include bridges, dams, buildings, roads, airplanes, rockets, software, and robots. The risk of an engineering project is the possibility that the project will fail to meet its objectives or constraints. Such as cost, time, quality, safety, and performance.

## How To Calculate? Calculating Risk in Investments and Engineering Projects

One way to calculate the risk of an engineering project is to use the failure mode and effects analysis (FMEA), which is a method of identifying and evaluating all the possible ways that a system or a component can fail, and their effects on the overall system or product. The FMEA assigns a risk priority number (RPN) to each failure mode based on three factors: severity (how bad is the effect), occurrence (how likely is the failure), and detection (how easy is it to find and fix). The higher the RPN, the higher the risk. For example, if a failure mode has a severity of 10 (catastrophic), an occurrence of 9 (very high), and a detection of 1 (very low), its RPN is 90 (very high).

Another way to calculate the risk of an engineering project is to use the Monte Carlo simulation (MCS), which is a method of generating random scenarios based on probability distributions and evaluating their outcomes. The MCS can estimate the range and likelihood of possible results for complex systems or processes that involve uncertainty and variability. For example, if an engineering project has several uncertain factors that affect its cost and duration, such as material prices, labor rates, weather conditions, design changes, and technical issues, the MCS can simulate thousands of possible scenarios and calculate their probabilities and impacts.

## Calculating Risk in Investments and Engineering Projects – Challenges

- Investments are more affected by external factors that are beyond the control of the investor or manager
- Engineering projects are more affected by internal factors that can be controlled or mitigated by the engineer or manager
- Investments are more focused on measuring financial losses or gains
- Engineering projects are more focused on measuring technical failures or successes
- Investments are more likely to have skewed or fat-tailed distributions
- Engineering projects are more likely to have normal or symmetrical distributions

### However, there are also some similarities and connections between these two fields. For example:

- Both investments and engineering projects require careful planning and analysis before making decisions
- Involve trade-offs between risk and reward
- Both investments and engineering projects can benefit from diversification and portfolio optimization
- Can use similar tools and techniques for risk management
