Question

1. a. list the 5 ms (inputs) to the technology systems model.

b. why is each important to consider?

1. what feature distinguishes a closed - loop from an open - loop system?

Explanation:

Question 16 A

The 5 Ms (inputs) to the Technology Systems Model are Manpower (human resources), Materials (raw materials or components), Machines (equipment/tools), Methods (procedures/processes), and Money (financial resources). These are core inputs for technological systems to function, covering human, physical, procedural, and financial aspects.

• Manpower: Important as skilled/unskilled labor is needed to operate machines, manage materials, and execute methods. Without appropriate human resources, the system can't function efficiently.
• Materials: Essential because they are the raw inputs transformed into outputs. Quality and availability of materials affect the end product/service quality and production continuity.
• Machines: Critical for performing tasks, especially repetitive or complex ones. Advanced/well - maintained machines improve productivity, precision, and output quality.
• Methods: Necessary to define how tasks are done. Efficient methods optimize resource use, reduce waste, and ensure consistency in output.
• Money: Required to acquire materials, machines, hire manpower, and develop methods. Adequate financial resources ensure the system can be established, operated, and maintained.

The key feature distinguishing a closed - loop from an open - loop system is the presence of a feedback mechanism in a closed - loop system. In an open - loop system, there is no feedback; the output is not used to adjust the input or the process. In a closed - loop system, the output is monitored, and feedback is sent back to the input or the controller to adjust the system's operation, aiming to achieve the desired output more accurately.

Answer:

The 5 Ms (inputs) to the Technology Systems Model are: 1. Manpower (human resources involved in the system), 2. Materials (raw materials or components used), 3. Machines (equipment and tools utilized), 4. Methods (procedures and processes followed), 5. Money (financial resources to support the system).
