Design Process and Project Mgt
Many models and tools Design Process
o Mechanical Engineering • Ullman’s - 6 steps
o Engineering Your Future• 10 steps
o Different Companies use different models • They all use some process
Avoid “hobbyist approach” and inefficient project progress
EPICS teaches a model that fits community-based designs
EPICS Design Process
Six Phases
1. Problem Identification
2. Specification Development
3. Conceptual Design
4. Detailed Design
5. Production
6. Service/Maintenance
7. Redesign or retirement

Problem Identification
Tasks – o Identify problemo Determine project objectiveso Determine motivation for projecto Identify outcomes or deliverableso Determine duration of the projecto Identify community partner contact
Deliverables - Project Charter
Specification Development
Tasks o Complete users and beneficiaries analysis o Define the customer requirements o Evaluate design constraints o Develop engineering specifications o Compare to benchmark products (prior art)o Determine design targets
Deliverables- Project Specification Document
Conceptual Design
Tasko Complete Functional Decomposition of
projecto Complete Decision Matrix of requirementso Define how users will interact with projecto Analyze/evaluate potential solutionso Choose best solution
Deliverables- Project Conceptual Design Report
Detailed Design Tasks
o Complete top down specification/ bottom-up implementation (freeze interfaces)
o Analysis/evaluation of project, sub-modules and/or components
o Prototyping/proof-of-concept of project, sub-modules and/or components
o Field test prototype/get feedback from userso Complete DFMEA analysis of projecto Determine what user training is necessary
Deliverables o Project Detailed Design Reporto Prototype version of project
Production Phase
Taskso Complete production version of the projecto Complete user manuals/training materialo Complete delivery review
Deliverableso Delivered projecto Project Delivery Report o Delivery checklisto User manuals
Service/Maintenance Phase
Taskso Evaluate performance of fielded projecto Determine what resources are necessary
to support and maintain the project
Deliverableso Fielded Project Report

Seeking and Selecting
Each phase of the design process has divergent (creative) steps and convergent
steps where options are selected

Design Record A design record is a (short) report of an engineering
analysis that has been completed regarding your project. o They should be named as follows:
• TEAM-PROJECT-SEM-Number (example SLAC-VLM-F04-1). Example activities recorded in a Design Record:
o Circuit simulationo Education materials o CAD modeling of projecto Safety calculationso Experimental measurementso Design rational: Why did you choose a particular design
approach, algorithm, etc.o Component selection: Why did you choose a particular
component? Sr. Design Students should Author Design Records
Design Decision Table
A table with summarizes design decisions which you have made.
They should reference a Design Record.Design decisions could include:
o Architectureo Algorithmso Tools/Environmento Component selectiono Material selection
