Design Projects
Project Management
Many of our BSME graduates early in their careers find themselves
managing projects.
Following years of project management, a good number go on to
program management.
It’s What ME’s do …
Effectively and efficiently using the resources available to bring the
project to a successful conclusion.
Project Management
• Time• Money• Facilities and Equipment• People
Resources
• Once it’s gone, it’s gone
• Manage project time w/ Gantt chart
• Manage individual time w/ schedule/calendar
• 2nd most difficult resource to manage
Time
• A graphical representation of the duration of tasks against the progression of time
• Use for scheduling & planning (Begin with course calendar)
• List tasks and their time periods
• Living document
• Identify critical time paths
Gantt Chart
Typical Gantt Chart
From: http://www.jiscinfonet.ac.uk/InfoKits/infokit-related-files/gantt-chart-pic/view
• Progress• Problems• Plan
Weekly Meetings
• Financial Planning• Budget Tracking• Budget OveragesAny projects that will expend more than $1000 must provide a rationale to their faculty advisor, who must submit a budget overage request to Dr. R.

• Computers & Data Projectors• Digital Cameras• Computer Software• Shared Computer Drives• Machine Shop• Meeting Rooms - Teleconferencing• ME IPL (Industrial Projects Lab)• Video Conferencing
Facilities and Equipment
• Professional Advisor• Faculty Advisor• Other Faculty• Dr. R.• Jill Bielawski• Roy Bailiff• Craig Gunn• Software Consultants
People
• Act professionally• Communicate• Maintain high morale• Organize a fair workload
Identify major groups of tasks
PeopleYour Student Design Team
Major Task Groups
• Liaison– Communication
• Logistics– Order and Order Tracking
• Planning– Gantt Chart, Meeting Chair
• Reports & Records– Web, Network files, Report Follow-up
Your First Team Task:Define The Problem
• A good Problem Definition is– A set of REQUIREMENTS for good solution – A set of SPECIFICATIONS for good solutions
• A good Problem Definition allows– UNAMBIGUOUS SELECTION of the best
solution to THE problem from a set of possible solutions.
Definition Parameters(see Design Parameters.pdf on the web)
• 26 are listed… Don’t use them all
• Pick a smaller relevant set
Function/performance , Product cost , Delivery date , Quantity , Environmental issues , Safety , Quality , Energy consumption , Reliability , Maintenance , Mechanical loading , Size , Weight , Spatial constraints , Aesthetics , Transportation and packaging , Personnel , Service life , Noise radiation , Operating instructions , Human factors , Health issues , Government regulations , Shelf-life storage , Operating costs , Environmental conditions , …
Bad DefinitionThe design must be
LightInexpensiveSafeSmall Easily usedAsthetically pleasing… (The list is long)
These are unusable to evaluate & rank potential solutions because they do not allow unambiguous selection of the best design
Better Definition …The design must• be lightweight. Acceptable designs will weigh
less than 5 pounds. Design quality is inversely related weight measured in pounds. (W < 1 lb => 5, W>10 lb => 1 in decision matrix)
• Be inexpensive. Acceptable designs will cost less than $9.59 to produce. Design quality is inversely related to manufacturing cost in US dollars ($).(Cost < $1=> 5, Cost>$10 => 1 in decision matrix)
Definitions• Include both
– Constraints: Limits of measurable performance qualities
– Objectives: Statement of what measurably objectively changes as solution quality changes.
• May be Qualitative or Quantitative– BUT all elements must be unambiguous– DEFINE Qualitative Scale
Qualitative Scale
On a 1-5 point Scale … (You can do better)
5 Best in Class performance
4 Better than 90% of Competitors
5 Better than 75% of Competitors
2 Better than 50% of Competitors
5 Worst in Class performance
The key… Define how you will evaluate solutions BEFORE you develop them
