Right Answer: A database index improves the performance of queries by allowing faster access to rows, reduces the amount of data that needs to be scanned, and can enforce uniqueness. A composite key is used to uniquely identify a record using two or more columns, which helps maintain data integrity and allows for more complex relationships between tables.
Right Answer: When a project is delayed, we assess the situation to identify the causes, communicate with stakeholders, adjust the project schedule, allocate additional resources if necessary, and implement corrective actions to get back on track.
Right Answer: Project selection methods are techniques used to evaluate and choose projects based on their potential value and alignment with organizational goals. Common methods include:
1. **Cost-Benefit Analysis**: Comparing the expected costs and benefits of a project to determine its feasibility.
2. **Scoring Models**: Assigning scores to projects based on predefined criteria to rank them.
3. **Payback Period**: Calculating the time it takes to recover the initial investment from the project's cash flows.
4. **Net Present Value (NPV)**: Assessing the profitability of a project by calculating the difference between the present value of cash inflows and outflows.
5. **Internal Rate of Return (IRR)**: Determining the discount rate that makes the NPV of a project zero, indicating its potential return.
6. **Portfolio Analysis**: Evaluating projects as part of a larger portfolio to balance risk and return.
7. **Expert Judgment**: Relying on the insights of experienced stakeholders
