Design Process 2.0

Question 1

Stakeholder analysis

Answer 1

Y axis - level of power and control
X axis - Level if interest
Bottom left sector - Low priority
Top Left Sector - Keep Satisfied
Bottom right sector - Keep up to date
Top right sector - Most important key players

Question 2

Needs assessment

Answer 2

Asking a bunch of questions to help define the problem
However, not all needs will be identified at the beginning of the design process
The needs assessment is used to produce the PDS

Question 3

Subtitles of PDS

Answer 3

Product identification - key criteria
Special features
Key performance targets
Service environment - environment conditions
Key Project Deadlines
Physical Description
Manufacturing specifications
Market identification - identifying the market that the product will be in
Financial Requirements - money details
Life cycle Targets
Social, Political & Legal requirements

Question 4

Brainstorming stages

Answer 4

Brain dump phase
Idea trigger phase - share ideas and trigger new ideas
Compilation phase - discuss, develop and discard

Question 5

Objective tree

Answer 5

Method of idea generation
Look like probability trees
First branch gives a aspect of the design
Secondary branches are ideas to resolve the aspect

Question 6

Morphological Analysis

Answer 6

Write a column of the features
In each row, give solutions to each feature
The thing we did for design project 2

Question 7

PMI

Answer 7

Gives a list of plus, minus and interesting aspects of an idea
Assign points to each aspect, depending on the importance of the aspect
Plus ideas get + points
Minus get - points
Interesting gets either + or -
Add up points and then compare totals to other ideas

Question 8

MART

Answer 8

Multi-Attribute Rating technique

Question 9

Weighting Matrix

Answer 9

Each criteria is compared to each other, and given 2,1 or 0 points depending on this comparison
Then once this is done the criteria will add all the points it got to get a final weight

Question 10

Valuation of Alternatives

Answer 10

Each aspect for each design is given points 0-4 depending on how well it fits the criteria
These points are then multiplied by the weighting’s for each criteria to get a final rating
The design with the highest rating should be chosen

Question 11

Trade Off Analysis

Answer 11

PMI and Mart are examples of this
Used to find the best option
PMI used for simple problems
MART used for more complex

Question 12

Validating the design

Answer 12

Market testing
Peer review
Mathematical Modelling
Simulation
Experimentation

Question 13

Next steps in design process

Answer 13

Build
Test
Acceptance - accepted by client
Operations & Support - design is manufactured
Maintenance

Question 14

Iteration

Answer 14

Design is non linear and the design is constantly developed and improved as it progresses through the design process. Going backwards is part of the design process and necessary the test, check, validate and modify/redesign or even start again

Question 15

What is a concept design

Answer 15

A concept design is an outline solution
That identifies all key components
Detailed enough to prove all feasibility of the concept
Detailed enough to be developed into a final design by others

Question 16

What is PDS and why is it important

Answer 16

PDS is a definition of what the stakeholders want/need, usually contains outcomes, functional requirements and key parameters
PDS should be unambiguous and should not be open to interpretation at a later date as this causes confusion and disagreement about what has been designed and what was intended

Question 17

Main sections Of PDS

Answer 17

User requirements
Constraints and Controls
System Requirements

Question 18

Parallel Design

Answer 18

Multiple designs are developed simultaneously with iteration occurring for all designs
Parallel design improves the final design as each idea is fully developed and so strengths from each design can be used in the final design
