SVES Colleges of Engineering
UML – ATP
Lecture 2
Step One
Research the Problem
• Gather all the information needed to
consider this project
• Define the Problem
• Completion is realized with a
project proposal
Step Two
Define the Problem
• Study the problem and list as many facts
as possible to fully define the problem
• Completing the design specifications
• Set Objectives
• Outcome is a set of specifications
Step Two
Develop Design Specifications
Define the Problem
• Specifications are a formal document
listing the requirements of a project
• Define details that must be met
• Can be used as a guide in future projects
• Market Specifications
Develop Design Specifications
& Specification Format
•
•
•
•
•
•
•
•
•
General description
Performance
Power requirements
Packaging
Environmental
Operation
Project and production cost
Agency approvals
Special requirements
Develop Design Specifications
Packaging
•
•
•
•
•
Mechanical size limits
Environmental rating
Shape
Material
Human engineering aspects
Develop Design Specifications
Environmental
•
•
•
•
•
Ambient temperature
Humidity
Vibration
Shock
Electromagnetic interference (EMI)
– Immunity
– emissions
Develop Design Specifications
Manufacturing Cost Goal
• Total cost of purchased parts
• Labor cost to manufacture
• Manufacturing overhead
• The projected costs should be stated at
the volume of manufacture for the costs
Develop Design Specifications
Software
• Outline of the planned method of software
operation
• All operations that involve the end user
• All operations that involve the hardware
• Flow charts ( top level )
• Flow charts ( sublevel operations )
Step Three
Plan the Solution
•
•
•
•
Develop a Plan
Outline Strategy
List steps intended to solve the problem
Outcome is a Project Schedule
Step Four
Execute the Plan
•
•
•
•
•
Preliminary design
Component selection
Breadboarding
Prototype development
Outcome working Prototype
Step Five
Verify the Results
•
•
•
•
Test design to set design specifications
Review measured results to specifications
Does it meet the specifications ?
Outcome is a reasonable solution to the
problem
Step Six
Develop a set of conclusions
• Results of the project are summarized
• Design improvements and performance
monitoring
• Design documentation
• Outcome is a Final Report
