Engineering design is a process that applies science and math principles to optimally convert resources to meet a stated objective. It involves research, modeling, implementing, measuring, and communicating. The engineering design cycle includes input, research, modeling, implementing, measuring, and communicating output. Tools used in engineering design include functional decomposition or block diagrams to break down a system, Gantt charts for project scheduling, and a project manager to balance cost, schedule, and performance. Defining and specifying a project outlines precisely what is to be done under the constraints to achieve an optimal outcome.

1. Engineering Design

2. Engineering Design
The process of devising a system, component,
or process to meet desired needs.
It is a decision-making process, in which the
basic science and mathematics and
engineering sciences are applied to convert
resources optimally to meet a stated
objective.

5. Tools in Used in Engineering Design
• Functional Decomposition or Block Diagram
• Gantt Chart
• Project Manager

6. Functional Decomposition or Block
Diagram
Breaking the system down into its functional part to
understand how this parts operate with respect to
the whole.

7. Gantt Chart
Type of bar chart that illustrates project schedule.

8. Project Manager
A person that balances the cost, schedule and
performance.

9. Project Definition and
Specification

10. Defining a Project
1. Is the problem important?
2. Is the problem solvable?

11. Specifications
• Outline as precisely as possible at a given
stage of the project what you are supposed to
do.
• It characterizes what you produced and how
to use it.
• Specifications are a form of contract.

12. A Good Specification
• State exactly what you are going to do, not
how you are going to do it.
• You need to develop a clear mental image of
what you are designing.

13. Pointers in Design Specification
• Constraints
External factors that will limit your exploration space.
• Standards
Standards allow us to communicate complex
constraints in a minimal number of words.
Standards make sure our work is compatible with
others.
