RESPONSE

1. Explain the concept of system design and how it approaches product specifications.

Systems design is defined as a process of defining the hardware and software architecture, components, modules, interfaces,
and data for a system to satisfy specified requirements. In other words, systems design is the preparation of an assembly of methods, procedures, or techniques united by regulated interaction to form an organized whole. Products specification is one of these methods. In other words, products specification is incorporated into the overall systems design to meet the initial stated goals and objectives of the demands of the system design. Let's look at an example, of one generic product design, which is part of an overall systems design and how it approaches product specification as one of the steps in the process.

Example:

A systems design, such as ISO/TR 14062, includes a product design and development model as part of their systems design system. For example, a generic model of product design and development in ISO/TR 14062 consists of six stages (and as we will see, product specification occurs in the detailed design stage and is checked in the testing/prototype stage of the design):

1. Planning,
2. Conceptual design,
3. Detailed design,
4. Testing/prototype,
5. Market launch, and
6. Product review.

1. The planning stage encompasses planning and formulation of product requirements.
2. The conceptual design stage is for defining the requirements for the product.
3. The detailed design stage is for meeting the product design specification and specifying the product prior to production or introduction into service.
4. The testing/prototype stage is for checking the detailed design against environmental targets and other product specifications. The environmental performance of the product such as life cycle assessment results can also be assessed in this stage.
5. The market launch stage consists of delivering the product to the market and communicating information on the product's features and benefits to the customers.
6. Lastly the product review state involves reviewing the entire product design and development process.

2a. Discuss how to convert the PERT diagram to a system design.

The PERT diagram is part of the overall system design. It is not converted to a system design, per se, rather it is part of the overall system design process.

Lets look at an example of a checklist of the tasks involved in a systems design to get an idea of what it entails. For example, in number 7 below, the PERT diagram is used to indicate the estimated schedule of the project. The information in the chart assists in assigning tasks (see http://66.102.7.104/search?q=cache:dRHM8JcDKiIJ:www.montgomerycollege.edu/faculty/~rcromwel/public_html/2chapter.ppt+convert+the+PERT+diagram+to+a+system+design&hl=en).

Example of one Systems Design (and where PERT fits into the overall design process): (excerpt)

Solution Summary

This solution explains the concept of system design and how it approaches product specifications. It details how to convert the PERT diagram to a system design. The value of design reviews is explained, including how often they they should occur as well as who should be there, and why.
