NSEI 6.1 WARM-UP

NSEI 6: REVIEWING DESIGN FEEDBACK

Interns actively read the feedback letter and discuss as a group in order to set goals for the criteria and prepare for final iterations. (15 min)

To understand whether the

feedback suggests that your

results are strong, moderate,

or weak, look for phrases that

state if something is good, just

okay, or not great and needs a

lot of improvement. These

phrases are clues for how to

make changes to your next iterations.

•Each Design Team has submitted a

design to Ken Tapaha and you will use it

to demonstrate how to interpret his

feedback.

•The project director has given

suggestions, but not answers, about

how to improve your designs. Look for

whether your design strongly,

moderately, or weakly addressed each

criterion.


I highlighted parts of this section in green

because the language

suggests that

you strongly addressed

the criterion of

Minimizing Drug Resistance.


I have highlighted in yellow the portions of

this section that state

you have moderately

addressed the criterion of Patient Side Effects.


I have highlighted in pink the portions of

this section that state

you have weakly

addressed the criterion

of Treatment Cost. Your

design is too expensive.


You will use this table

to help them

summarize the

feedback they received

from Ken Tapaha.

Connect feedback from

your example letter to the criteria in the table.


Locate the design they

submitted and to

complete the first row

on the Design

Feedback Summary

sheet with their test results.


As you read your feedback

letters, interns will record

notes in the second row of

the table on the Design

Feedback Summary sheet.

If you are providing printed

feedback letters, let interns

know that they can annotate

the printed letters and then

transfer notes to their

Design Feedback Summary sheets.


Color-code your entries on

the Summary sheet, using

the highlighters to indicate

whether the feedback

suggested their design

strongly, moderately,

or weakly addressed the

criteria. In this example, it is

clear that the design

strongly addressed the

criterion of Minimizing Drug

Resistance, but needs work in the other criteria.


Who received

feedback that

indicated their

design strongly

addressed the

criterion for

Minimize Drug

Resistance to

share their values.


Who received

feedback that

indicated their

design

moderately

addressed the

criterion for

Minimize Drug

Resistance to

share their values.


You will have

some time today

for more iterative

testing to improve

upon their designs.

NSEI 6: REVIEWING DESIGN FEEDBACKIt is very hard to

address all three

criteria equally well,

but it’s important to

try to improve your

designs as much

as possible for

each criterion.

Sometimes, to

strongly address

one criterion, you

have to moderately

address another.

These are trade-

offs, and you

probably

experience these

trade-off decisions

in your daily lives.


A trade-off happens in a

situation where a design

has good results in one

criterion but not in

another. Often, you will

find that you need to

prioritize one criterion

over another when

considering changes to your designs.


Remember, the point of

iterative testing is to

gather information that will

help inform and improve

your next test. Based on

the ranges from Ken’s

feedback, you should set

a target value in the third

row of the Design

Feedback Summary. Then

describe a strategy for

achieving those targets in

the last row. For example,

to reduce cost, I can use

less of Drug A and more

of Drug C.

To reduce cost, I can

use less of Drug A

and more of Drug C.

Complete a redesign strategy for each criterion, based on these ranges and on the analysis of your feedback letter.

NSEI 6: LEARNING ABOUT OPTIMAL DESIGNS

It was nearly impossible

to strongly address all

three criteria equally, so

interns had to make

choices, prioritize each

of the criteria, and

accept trade-offs.

Through this process,

they should have a

better idea of what their

optimal design might look like.

NSEI 6: LEARNING ABOUT OPTIMAL DESIGNS

Video Engineering Tip: Optimal Designs.

•In order to identify an optimal design you

must decide on a priority.

•Since each project has several criteria,

there will be trade-offs among them,

especially when you plan designs that

target or emphasize one priority over the

other criteria.

•Each engineer’s optimal design may be

different from another based on the priority

they set and the trade-offs they accept.
