What characterises a critical system in terms of its operation and evolution?
What characterises a critical system in terms of its operation and evolution?
- It is costly to maintain and evolve, but highly reliable.
- It can undergo changes frequently, but at high costs.
- It must be highly reliable and maintain that reliability as it evolves without excessive costs. (correct)
- Its reliability is optional as long as costs are minimal.

What distinguishes a mission-critical system from other types of systems?
What distinguishes a mission-critical system from other types of systems?
- It is required to be highly reliable.
- Its failure leads to the failure of a specific goal-directed activity. (correct)
- Its failure leads to potential injury or loss of life.
- Its failure results in high costs for the business.

Study Notes
- Critical systems must be highly reliable and retain their reliability as they evolve without facing excessive costs.
Safety Critical Systems
- Failure can lead to injury, loss of life, or major environmental damage.
- An example is a control system for a chemical manufacturing plant.
Mission Critical Systems
- Failure results in the failure of a goal-directed activity.
- An example is a navigational system for a spacecraft.
Business Critical Systems
- Failure may cause substantial expenses for the business using the system.
- An example is a customer accounting system in a bank.
Dependability
- In systems engineering, dependability measures availability, reliability, maintainability, and sometimes durability, safety, and security.
- In real-time computing, dependability concerns providing trustworthy services within specific timeframes.
System Dependability
- Availability measures the system's ability to deliver services when required.
- Reliability measures the system's ability to consistently deliver services as specified.
- Safety measures the system's ability to operate without catastrophic failure.
- Security measures the system's capability to protect against accidental or intentional intrusion.
Safety-Critical System Example
- A software-controlled insulin delivery system uses a micro-sensor to measure blood parameters proportional to sugar levels.
- The pump controller receives data, calculates sugar levels and insulin needs, and signals a miniaturized pump to deliver insulin through a needle.
Insulin Pump Dependability
- The system should always be ready to deliver insulin when necessary.
- Insulin pump systems need to reliably deliver the correct amount of insulin to counteract blood sugar levels.
ERP Systems
- Enterprise Resource Planning (ERP) integrates main business processes in real time through software and technology.
- ERP systems are business management software suites that collect, store, manage, and interpret data from various business activities.
Odoo
- Odoo is a suite of web-based open-source business applications.
- Main applications include Open Source CRM, Website Builder, eCommerce, Warehouse Management, Project Management, Billing & Accounting, Point of Sale, Human Resources, Marketing, and Manufacturing.
- Odoo applications can be used on their own or integrated for a full-featured Open Source ERP system.
