Human-Centered Design

Human-Centered Design as a Process

Human-Centered Design as a Mindset

EPICS Design Process

Project Identification Phase

Project Identification Phase: Goal is to identify a specific, compelling need to be

addressed

Com

mon t

ask

s

Conduct needs assessment (if need not already defined)

Identify stakeholders (customer, users, person maintaining project, etc.)

Define basic stakeholder requirements (objectives or goals of projects and

constraints)

Determine time constraints of the project

Gate 1: Continue if have identified appropriate EPICS project that meets a

compelling need

Specification Development Phase

Specification Development Phase: Goal is to understand “what” is needed by

understanding the context, stakeholders, requirements of the project, and why

current solutions don’t meet need, and to develop measurable criteria in which

design concepts can be evaluated.

Understand and describe context (current situation and environment)

Create stakeholder profiles

Create mock-ups and simple prototypes: quick, low-cost, multiple cycles

incorporating feedback

Develop a task analysis and define how users will interact with project (user

scenarios)

Compare to benchmark products (prior art)

Develop customer specifications and evaluation criteria; get project partner

approval

Gate 2: Continue if project partner and advisor agree that have identified the

“right” need, and if no existing commercial products meet design specifications.

Conceptual Design Phase

Conceptual Design Phase: Goal is to expand the design space to include as many

solutions as possible. Evaluate different approaches and selecting “best” one to

move forward. Exploring “how”.

Conduct Functional Decomposition

Brainstorm several possible solutions

Create prototypes of multiple concepts, get feedback from users, refine

specifications

Evaluate feasibility of potential solutions (proof-of-concept prototypes); select

one to move forward

Gate 3: Continue if project partner and advisor agree that solution space has

been appropriately explored and the best solution has been chosen.

Detailed Design Phase

Detailed Design Phase: Goal is to design working prototype which meets

functional specifications.

Com

mon t

ask

s

Design/analysis/evaluation of project, sub-modules and/or components

(freeze interfaces)

Complete DFMEA analysis of project

Prototyping of project, sub-modules and/or components

Field test prototype/usability testing

Gate 4: Continue if can demonstrate feasibility of solution (is there a working

prototype?). Project Partner and advisor approval required.

Delivery Phase

Delivery Phase Tasks: Goal is to refine detailed design so as to produce a product

that is ready to be delivered! In addition, the goal is to develop user manuals and

training materials.

Common tasks: Complete user manuals/training material

Complete usability and reliability testing

Complete delivery review

Gate 5: Continue if Project Partner, Advisor and EPICS Admin agree that project

is ready for delivery!

Service/Maintenance Phase

Service/Maintenance Phase Tasks

Common tasks: Evaluate performance of fielded project

Determine what resources are necessary to support and maintain

the project

Gate 6: Project Partner and Advisor approve continued fielding of project. If not,

retire or redesign.

Retirement or Redesign Phase

Retirement or Redesign

Why is design difficult?

Engages different types of thinking

o Design is one of the most cognitively complex forms of “problem solving”

Requires designers to manage so many ideas and aspects

Addresses different types of problems

o Ill-defined

o Complex (number of requirements and constraints)

Seeking and Selecting

Divergence Convergence

Expand possibilities Narrow Focus

Name the

problem

What will could I or others do in light of this learning

Can be applied to personal/professional, disciplinary, and civic learning.
